Insulation of the warehouse. Insulation of warehouse walls

For development industrial production, wholesale trade, the logistics business always requires the availability of warehouse space of decent size. In addition, warehouse stores and online trading platforms that do not have separate areas for selling goods are becoming more widespread.

What's the problem?

Of course, it is not particularly difficult to erect a small warehouse building from materials that already have heat-saving properties. But if we are talking about areas and volumes for organizing the storage of products, raw materials or goods, amounting to hundreds and thousands of square and cubic meters, That traditional ways construction will not be economically justified.

Hangars and warehouses of large areas are most often built according to frame technology or using prefabricated structures. An example is the well-known arched metal structures assembled from steel sections wave-shaped.

The steel sections do not retain heat at all in winter and do not protect the internal volume from heating in the sun in summer. There are also warehouse structures made from concrete slabs, also requiring thermal insulation. What methods and materials are used to improve hangars and other large premises?

Methods for insulating structures made of metal and concrete

Among the variety of methods for preserving heat in a warehouse, several basic ones that are acceptable in terms of efficiency deserve attention.

Method 1: Creating an Inner Outline

The method of insulation by building an internal contour consists of erecting a lightweight, insulated, non-load-bearing frame structure inside the hangar.

Installation can be done according to various technologies- using wooden slatted or metal profile frames with the installation of foam or slab insulation in them and then facing with panels.

Significant disadvantages of the method are the reduction in the usable area of ​​the warehouse and the high cost of the structure.

Method 2: insulation with basalt and glass wool slabs

Insulation with slab, basalt or glass wool material as a method is effective in terms of heat conservation, but is inconvenient to implement. Essentially, this is the same option as with internal contour, but the frame is mounted directly on the walls of the warehouse.

This places additional stress on the hangar sections and may affect its stability. In addition, it may be difficult to attach slats or profiles to steel walls. Another disadvantage of this method is that moisture inevitably accumulates in the thickness of the insulation and does not escape.

Method 3: foam as insulation

Polyurethane foam insulation has become popular. This material exists in two forms - in the form of slabs and in the form of a liquid mixture, which foams on its own after application. Plates are used to insulate the external surfaces of wooden or concrete walls, and foam is used to treat indoor walls. Liquid polyurethane is probably the most suitable insulation for steel structures.

Construction foam has good adhesion to any surface. Its thermal conductivity properties do not depend on the shape of the walls, and the degree of insulation can be adjusted by the thickness of the layer. The disadvantage can be considered the inability to process when negative temperatures air and walls.

Materials: properties and comparison

Let's consider several main characteristics that are essential specifically for insulation of warehouses and hangars:

• thermal conductivity, i.e. the degree of insulation of a layer of a certain thickness;
• flammability or ability to sustain combustion. The fire protection of premises depends on this parameter;
• specific gravity or the load that the building structure will bear due to insulation.

This insulator has the following characteristics:

• specific thermal conductivity: about 0.030 W/m*K. This figure characterizes both glass wool and basalt materials;
• flammability: do not burn and do not support combustion. Glass wool slabs can withstand temperatures up to 400°C without loss of properties, and basalt fiber slabs can withstand temperatures up to 1000°C. The walls of a warehouse covered with basalt fiber can withstand open fire for a long time;
• specific gravity: depends on the density of the slab and ranges from 35 kg/m3 to 180 kg/m3. For insulation steel wall A 15 cm layer with a density of 100 kg/m3 is sufficient. Thus, for an area of ​​1 m2 the load will be 15 kg.

Polystyrene foam and polystyrene foam

Polystyrene foam or expanded polystyrene in solid, slab form have the following qualities:

• thermal conductivity: for foam plastic - 0.037 kg/m3, for expanded polystyrene - 0.027 kg/m3, which is quite comparable to the characteristics of mineral wool;
• degree of flammability: polystyrene foam and expanded polystyrene can burn, however, in modern production, fire retardants are added to them, which allows these materials to be assigned a flammability class of G1 and called non-flammable. The heat resistance of foam materials is low - they cannot withstand heating even up to 250-270°C, and when burned they emit gases that are dangerous to humans;
• specific gravity: polystyrene foam - 100 kg/m3, polystyrene foam - 40 kg/m3, polyurethane foam ( polyurethane foam) - 40-80 kg/m3. 1 m2 of polystyrene foam with a layer of 15 cm will weigh 15 kg, polystyrene foam - only 6 kg, and polyurethane foam - from 6 to 12 kg.

Insulation materials such as polyurethane or construction foam have the same characteristics as slab polyurethane foam materials.

Comparative analysis

A basic comparison of characteristics shows that the degree of insulation of all materials is almost the same; polystyrene foam and polyurethane foam have the minimum weight. Moreover, the calculation did not include the weight of the frame structure, which is necessary if mineral wool or hard foam material. What is the safest way to use fire protection? stone wool. However, liquid polyurethane is the easiest to install.

Another important characteristic is the cost of materials. The most expensive are stone wool insulation, the cheapest are foam boards. The choice of thermal insulation for a warehouse depends on the design features, wall material and financial capabilities.

Installation work

The technology of insulation with fibrous and slab materials can be described in the following steps.

The frame is assembled from wooden slats(usually for foam plastic) or metal profiles.

The frame is fastened to the walls either with self-tapping screws or with dowels; metal profiles can be secured to steel structures using wire and welding. The thickness of the frame elements must correspond to the thickness of the insulation sheets.

To prevent the accumulation of moisture inside the mineral wool layers, it is advisable to place a vapor barrier on both sides, and if the installation is carried out outside the walls, a windproof, vapor-permeable membrane. The films should be secured with slack so that thermal fluctuations in the dimensions of the hangar structures do not damage them.

The frame is usually located inside the building. However, to preserve useful volumes, it is possible to insulate from the outside, followed by cladding.

Laying slabs

Plates, sheets or rolls are laid between slats or frame profiles and secured. Possible joints are carefully sealed with scraps of the same material or polyurethane foam.

Facing

It is carried out not only for the purpose of making appearance more presentable, but also to prevent damage to the insulation. Another technology is used to apply a layer of polyurethane to the walls. Liquid composition applied by spraying from special sprayers. Work must be carried out in protective clothing, and ventilation must be provided in the room.

After application, the composition expands on its own for some time and fills all the unevenness and cracks in the walls. The hardening time is about 1 hour. As a result, it appears textured surface, which can subsequently be painted with water-based paints.

Roof structure

The construction of roof structures is divided into attic and non-attic. Industrial buildings are made at a slight slope to drain precipitation; they are usually roofless. Attic types roofs are basically pitched structures with an inclination angle of about 30-70° and load-bearing elements in the form of rafters, large panels and trusses.

The rafters and trusses are covered with sheathing, usually made of wooden beams, or plank flooring. It serves as the basis for a roof made of rolls waterproofing materials. Additionally, before laying the rolled carpet, if there is such a need, vapor and heat insulation is made with special materials.

For spans of 10-12 m, they are built as a system with hanging rafters. It is a structure, the main load-bearing part of which is roof trusses resting on the walls of the building. A vertical headstock (suspension) is installed in the center of the truss. It is connected to the walls rafter legs, serving as a load-bearing basis for the roof. To give the structure rigidity, struts running from the base of the beam rest against them.

The following materials are most often used for this design:

• for hanging rafters - boards or beams;
• for the lower belt and tensile posts - steel profile or pipes;
• for farms - reinforced concrete or steel.

Single or gable roofs from large ribbed reinforced concrete panels are built with a central support, which can serve as interior wall. The panels rest on it and the outer walls of the structure. The span of the structure, as a rule, is 6-6.4 m. Fastening is steel anchors. Asphalt or cement strainer and the rolled carpet is glued. Nowadays, panels are predominantly made from waterproof concrete, which does not require waterproofing, so there is no need for it.

Industrial roofs of buildings with a height of more than two floors are protected with brick parapets.

Industrial roofing without purlins is formed by reinforced concrete slabs, which are both a load-bearing element and the base of the roof. Cold roof built from heavy concrete, after laying the surface is leveled with asphalt mastic or cement mortar followed by gluing the rolled carpet.

For insulation, foam concrete and mineral insulation are used, a screed is made on top of them and roll waterproofing is glued.

Sometimes flat roofs are made without a slope. To avoid overheating, in some cases they are protected by filling them with 5-15 cm of water; before the onset of winter, the water is drained.

Chimneys and ventilation outlets require a special device for connecting the roof to them. To do this, collars are made of tin, closely adjacent to the pipe; the collar is placed above the plane of the roof. If the covering is asbestos-cement slate, then the collar on the ridge side is inserted under the roof, and on the overhang side it is placed on top of the slate sheets.

Industrial buildings with a height of more than two floors are fenced with brick parapets or gratings according to MRTU 20-4-65.

Basic requirements for thermal insulation of industrial and administrative buildings

When we talk about thermal insulation of an industrial building, we immediately mean the presence of an aggressive environment, large areas, metal structures and, as a rule, short deadlines for completing work. Therefore, the materials that will be used to insulate an industrial building must:

• be installed quickly so as not to slow down production processes for a long time;
• do not be afraid of the alkaline and acidic effects that are present in the air;
• if possible, protect metal structures of walls and roofs from excess moisture and corrosion;
• inexpensive.

If there is a question about insulating an administrative building, then there are also some requirements:

• insulation should not spoil the overall aesthetic appearance of the building;
• be installed quickly, since the administrative building is constantly in sight;
• thermal insulation should have a low price
  ;
• The service life of the insulation should be as long as possible in order to avoid costly repairs.

And in both cases, of course, we should not forget about EFFICIENCY. The building must maintain the required temperature conditions.

As we can see, there are many requirements for insulation of industrial and administrative buildings and all of them are quite serious. But for sprayed polyurethane foam insulation this is not a problem.

Materials for insulation of industrial buildings

It is important to remember that the specifics of thermal insulation industrial buildings determined, first of all, by their purpose and location. In all cases it is required complex work to improve the overall thermal protection of the building

Therefore, it is quite logical that for each individual part of the structure should be used different material, suitable for specific purpose. You can read more about ways to insulate buildings here. For example, mineral wool slabs with combined insulation are best suited for roofing.

In general, the process of insulating an industrial roof includes several stages:

• Laying galvanized steel profile sheet.
• Installation of vapor barrier (polyethylene film).
• Installation of insulation (mineral wool).
• Installation polystyrene foam boards followed by installation of the roofing system.

Stages of thermal insulation of walls of industrial buildings

The load-bearing walls of the structure must be made of brick, concrete and its varieties (foam concrete, aerated concrete). The structure of these materials has specific features that prevent the passage of cold air.

When using cement or bitumen glue, PPS boards are installed. It is necessary to use only varieties that are designed specifically for the facades of premises. For greater safety, you can install fireproof cutouts made of mineral wool.

The final stage is to give the walls the desired appearance using decorative plaster. To do this, a reinforcing mesh is applied over the slabs, and then a layer of plaster.

This method insulating the walls of industrial buildings is very popular in Europe. Its peculiarity is that after using this technology there is no need to update the insulation itself. It is enough just to change the outer decorative layer from time to time, which can crumble over the years.

Speaking about industrial insulation, it is worth considering the fact that thermal insulation industrial buildings must be comprehensive. In this regard, we must not forget about floor insulation.

Stages of floor insulation

Installation of floor slabs to provide stability to the future insulated structure.

Laying PPS slabs. Their size depends on the area of ​​the room and is selected individually in each specific case.

Installation of the waterproofing layer.

The final stage is screed. Laying plywood and gypsum fiber to increase the thermal insulation properties of the floor, as well as the stability of the entire structure.

This insulation technology is usually used specifically for reinforced concrete coverings of premises (industrial buildings). She has best characteristics and is designed to increase the thermal stability coefficient of the building as a whole.

Features of industrial thermal insulation using polyurethane foam

The methods described above are classic and provide good performance in terms of thermal protection. However, technology does not stand still, and the thermal insulation of industrial buildings is also taking on new forms. In particular, this applies to the use of polyurethane foam (PPU), applied by spraying.

• Long service life. If technology is followed using modern equipment, polyurethane foam can last more than 50 years.
• Safety for human health.
• He endures negative impacts environment and is resistant to fungi and mold.
• No technological seams. Thereby thermal insulation characteristics industrial buildings are increasing significantly.
• The process of spraying polyurethane foam can be carried out in as soon as possible, which is also a plus for the entire production rhythm.

Of course, when insulating industrial facilities, many nuances always arise. This applies to both the choice of materials and the method of application (which in turn depends on the purpose of the object and its location).

Ignoring at least one of the points can significantly reduce the thermal protection of production premises, which will inevitably lead to additional costs in the future. Second required condition - A complex approach to the entire industrial facility. If these conditions are met, the best effect is achieved. And the process of insulating an industrial building will be practical and effective.

How to insulate a cold warehouse in winter

How to insulate gates in a warehouse

Photo: insulated warehouse gates

To insulate gates in a warehouse, you can use polystyrene foam or penoplex. The material is light, durable, and not afraid of precipitation. You can use sheets 50 mm thick, which are inserted into a frame made of 50x50 mm wood blocks. The timber is pre-treated with an antiseptic, and all remaining seams between the foam sheets are sealed with polyurethane foam.

When the entire gate area is insulated, moisture-resistant plywood or OSB is mounted on top. The whole technology is no different from insulating garage doors. The gate can also be insulated with mineral or glass wool, which is also placed in a frame made of wooden blocks. The width of the beam must correspond to the thickness of the thermal insulation layer, which can be calculated using a calculator.

Before installation basalt wool the entire frame and gate are covered with a moisture-proofing membrane. After laying the insulation, the frame is again covered with moisture insulation, so that the mineral wool is protected from getting wet on all sides. Next, bars are attached to the frame to create a ventilation gap so that moisture evaporates from the surface of the film, and the gate is covered with plywood or OSB.

How to insulate a roof in a warehouse

Insulation of a metal hangar roof

Insulation of a hangar roof is often difficult due to the significant height of the structure and its lightness, which is why it is often impossible to use heavy structures. A simpler, but more expensive way to insulate the roof in a warehouse is to hire specialists who will quickly spray polyurethane foam onto the structure. Polyurethane foam will create a continuous layer without seams and will not load the hangar roof.

A cheaper, but at the same time labor-intensive method is to create and insulate the ceiling. In many cases, this method is simply impossible to implement due to significant loads on the light structures of the walls and roof of the hangar. If the warehouse has concrete walls and ceilings, then there should be no problems. You can use any roll or slab insulation for this.

Mineral wool or expanded polystyrene slabs should be laid in a pre-constructed timber frame. The distance between the bars should be 1-1.5 cm less than the width of the mineral wool or glass wool sheets so that the insulation fits as tightly as possible to the bars. Additionally, the thermal insulation should be secured with dowels using fungi and covered with a vapor barrier to protect it from moisture.

How to insulate a concrete floor in a warehouse

Scheme of insulation of concrete floors on the ground

The concrete floor should be insulated during the construction of the hangar. Thermal insulation is produced by insulating the earthen floor with polystyrene foam or penoplex. Insulation slabs are laid on pre-leveled ground (to do this, fill the foundation from the inside with soil or sand). A caracas of reinforcement is knitted on top, and the floor in the hangar is filled with a thick layer of concrete.

If you need to insulate the floor in a hangar after construction is completed, then this work will require significant financial costs. Because it will be necessary to re-lay insulation and pour concrete where cars and forklifts will drive. In those rooms where there is no significant load, you can insulate the floors along the joists, using polystyrene foam or mineral wool as a heat insulator.

This floor insulation technology was described in detail earlier in the article “Floor insulation in wooden house which one is better” and will not be difficult. All work on insulating the hangar from the inside for the winter can be done in stages, so as not to completely stop the work of the organization.

The issue of insulating warehouses is as pressing as the problem of reducing heat loss in winter when the gates are open. Sometimes vestibules are used for these purposes, which significantly complicates the loading and unloading process. Another popular option is the use of heat guns, which can quickly warm up the air in the room after it has cooled down with the gates open.

Warehouses are designed to store various materials and goods. Often, storing certain groups of goods requires special conditions, including a certain temperature, humidity, and generally microclimate. To create these conditions, the room must be isolated as much as possible from the effects of conditions external environment, that is, to seal and thermally insulate. In cold climates, house facades are not able to retain heat indoors on their own. The result is high heating costs, the low efficiency of which is due to the high thermal conductivity of building materials.

POLYURETHANE FOAM – THE BEST SOLUTION FOR WAREHOUSES

Today, for thermal insulation of premises of any type, many modern insulation materials are used, which are designed to solve various problems. However, polyurethane foam, or PPU, is best suited for insulating warehouses. This heat insulator has unique characteristics that are still unattainable for other materials. In particular, polyurethane foam has the lowest thermal conductivity coefficient, which allows you to recoup investments in thermal insulation in just two seasons, and subsequently save up to 50% on energy resources for a long time.

PROPERTIES OF POLYURETHANE FOAM, SO NECESSARY WHEN INSULATING A WAREHOUSE

The only drawback of polyurethane foam is its exposure to ultraviolet rays. However, this problem can be solved by simply painting the thermal insulation with any paint that will protect the surface.

Naturally, it is impossible to create the necessary microclimate in the warehouse only by thermal insulation of the room. Therefore, in combination with insulation, it is necessary to take care of high-quality, well-designed ventilation. Such a complex will help make your warehouse premises ideal place for storing any goods.

Most modern private entrepreneurs, as well as various firms, enterprises and factories, have warehouses at their disposal. As a rule, they are stored in warehouses finished products, goods for sale, consumables, raw materials and much more.

Whatever is in these buildings, if the warehouse is not properly insulated, in cold winter or hot summer periods years, the contents of the warehouse run the risk of becoming unusable or losing their original characteristics.

Advantages of using polyurethane foam as roof insulation

Roof insulation using polyurethane foam has many advantages over other insulation materials:

• there is no need to dismantle the old roof;
• polyurethane foam insulation has the lowest thermal conductivity coefficient, which makes it possible to reduce the thickness of the thermal insulation layer;
• no special preparation of the roof surface is required;
• PPU material has great adhesion to most building materials;
• the ability of polyurethane foam to flow around surfaces of any shape and any bends;
• fill defects and cracks, forming a continuous, smooth, seamless coating;
• short deadlines for completing roof thermal insulation work using polyurethane foam (work speed is about 300 m2 per day);
• Icicles do not form on a roof insulated with polyurethane foam.

Thanks to the unique properties of polyurethane foam, it is possible to insulate the roof both from the outside and from the outside. inside. When applying polyurethane foam to the outer surface of the roof, the PPU coating must be protected from sun rays. For these purposes, you can use liquid rubber or urethane mastic. Coatings made from these materials will protect the thermal insulation layer of polyurethane foam from ultraviolet rays, create additional waterproofing of the roof and increase its service life.

When using sprayed rigid polyurethane foam for roof insulation in comparison with traditional methods thermal insulation saves time by 80%, and saves money by 50%. In terms of quality and durability, PU foam insulation technologies are many times superior to other insulation methods.

When repairing roofs with polyurethane foam, there is no need to remove the worn-out coating; in addition, all structures present on the roof are additionally sealed, and the absence of thermal bridges prevents the formation of condensation. During roof thermal insulation work using polyurethane foam, there is no need to stop the activity of the entire room, which is also an important advantage of using polyurethane foam.

Polyurethane foam is applied to the surface using a special spraying unit high pressure and within a few minutes the polyurethane foam becomes rigid.

Nuances of fastening insulation

Whatever material is chosen, it must be firmly fixed to the base. For these purposes, you can use two methods:

1. Bonding to bitumen. A labor-intensive and expensive process, justified only if there is concrete base, since more expensive specialized dowels will not be required and there will be no need to drill holes for them.
2. Mechanical fastening using special telescopic dowels. They have a very wide cap, due to which they cannot pierce the waterproofing and thus do not violate the tightness flat roof.

There is a building rule according to which the waterproofing carpet is attached to the insulation in the same way as it is attached to the base. At mechanically fastenings, it is better to use a polymer-bitumen weldable material as a vapor barrier. Its special elasticity helps to tighten without consequences the small holes inevitably punched by the dowel on which the insulation is attached. If two-layer insulation is used, the slabs must be laid “in a staggered manner” so that the joints of the slabs of the lower layer are necessarily covered by the upper one. In this case, the so-called “cold bridges” do not form. Each insulation board is secured with at least two dowels.

The layers of the “roofing cake” must be securely fastened

Temperature and comfort inside a building largely depend on proper insulation of the flat roof. By choosing the right materials and carefully observing construction technology, you can get a magnificent structure that will last flawlessly for many years, both as a traditional covering and as the basis for a relaxation area, terrace or roof garden.

Calculation of the roof covering of an industrial building

Required heat transfer resistance.

The parameters of the enclosing structure are selected based on the required heat transfer resistance, calculated using the formula:

— heat transfer resistance of the enclosing structure; — estimated indoor air temperature (); — minimum temperature outside air(); n— coefficient taking into account the location of the enclosing structure, is adopted according to the table SNiP -3-79 (accepted for roofing n=1); — heat transfer coefficient, depends on the smoothness of the inner surface of walls and ceilings and takes values ​​according to SNiP (smooth ceilings); — heat transfer coefficient, determined according to SNiP (for roofing); - the standard temperature difference between the air temperature in the room and the temperature of the internal surfaces of the enclosing structures is accepted according to SNiP (based on the condition “industrial buildings with normal operation”); R— thermal resistance of the construction material, determined by the formula

- thickness of the total layer,

Thermal conductivity for normal mode and normal climate, i.e. mode A:

Knowing this, we derive from formula (*) the thickness of the roofing materials:

where is the thickness of the insulation, hence,

For roof insulation we use mineral wool mats, and for waterproofing - three layers of roofing felt on a bitumen base with a total thickness of 15 mm.

Thermal characteristics of roof insulation materials.

Table No. 2.

— mineral wool mats at density.

As waterproofing:

- roofing material for density and -bitumen for density. From here we find the average thermal conductivity value for waterproofing: .

We substitute these values ​​into the formula (**):

We round the resulting value to a multiple of 50 mm. Then, the thickness of the mineral wool layer should be at least 0.05 m

Examination.

Because — the condition for heat transfer of the enclosing structure is met, therefore, the calculation is correct.

Thermal inertia:

— thermal resistance of the i-th layer.

S 1 = 0.46 - heat absorption of mineral wool, W/ (m2*C);

S 2 = 4.425 - average heat absorption of roofing material and bitumen, W/ (m2*C);

d 1 = 0.05 - thickness of the mineral wool layer, m;

d 2 = 0.015 - thickness of three layers of roofing material on a bitumen base, m.

l 1 = 0.05 - thermal conductivity of mineral wool, W/ (m*C;

l 2 = 0.19 - average thermal conductivity of roofing felt and bitumen, W/ (m*C).

Conclusion: for roof insulation we use mineral wool mats, and for waterproofing - three layers of roofing felt on a bitumen base with a total thickness of 15 mm.

As a filler window openings We choose double glazing in metal frames.

Advantages of polyurethane foam insulation of buildings

Firstly, the thermal conductivity of polyurethane foam is quite low, so even with a small thickness of this insulation on the roof or walls of a building, we can always talk about high efficiency (30 mm polyurethane foam with a coefficient of 0.019 W/m*K).

Secondly, the closed cellular structure of polyurethane foam does not allow water or steam to pass through, so the water absorption rates of polyurethane foam are also low. And this speaks not only about preservation of insulation properties
throughout the entire service life, but also about the anti-corrosion protection of metal structures.

Thirdly, polyurethane foam is installed using a foam generator spraying method
, which implies the absence of fasteners, guides, as well as acceleration and simplification of the installation process. In addition, sprayed polyurethane foam is held so tightly that its dismantling is possible only by crude physical methods.

Fourthly, polyurethane foam is not afraid of exposure to any chemical reagents (except concentrated alkalis and acids).

Fifthly, polyurethane foam is applied to the surface in a seamless layer that completely repeats its structure and shape, so you don’t have to worry about a damaged facade. When insulating the facade of a building, you can always paint it with polyurethane foam, apply plaster over it, or use a ventilated facade system.

Choose single-layer or double-layer thermal insulation

First of all, you should consider the installation of a flat roof - insulation can be planned in two ways:

Single-layer thermal insulation system. home distinguishing feature: the entire insulating layer is made of flat roof insulation of the same density. If it is planned to construct a roof that is in use, then a concrete screed is laid on top of the heat-insulating layer. This system is most often used when repairing old roofs or in the construction of garages, warehouses and industrial buildings. The two-layer thermal insulation system is designed differently. Upper layer 30-50 mm thick is made of insulation of increased strength and density. It is designed to redistribute mechanical load. The lower one, with a thickness of 70 to 170 mm, performs the main heat-insulating function

This design allows you to significantly reduce the weight of the roof and, accordingly, reduce the load on the floors, which is very important when renovating old buildings. There are modern materials that combine the properties of both layers

These insulation materials have a hard top edge and a softer bottom edge. Installation of such slabs occurs very quickly and reduces the time and labor costs for installing the coating.

The two-layer system guarantees the absence of through seams in the thermal insulation layer

To get rid of the so-called “cold bridges” in warehouses, it will be necessary not only to seal all the cracks. Considering that such rooms have a large area, all walls must be well insulated. It is necessary to get rid of such a phenomenon as leakage of warm air.

What is the difficulty?

Today, when constructing new warehouses, they are immediately used. But what to do if this is an old room and it is necessary to place goods in it, which must be stored at above-zero temperatures in winter? In this case, you need to think about performing repair and finishing work using insulation. And first of all, you will need to insulate the walls. But no matter what kind of insulation is used, it will be of little use if the issue with the gate is not resolved.

The thing is that the gates of many warehouses open almost every day to carry out the process of unloading and loading products from trucks. Therefore, two questions need to be resolved at once:
— the gates must be opened for the shortest possible time;
— the process of loading and unloading goods must be minimized in time.
In most cases, hangars and warehouses have a large area. In addition, they are built using a special frame technology. During their construction, metal structures and steel sections are used, which are completely unable to retain heat. Therefore, they must first be insulated.

Not every warehouse can suspend its activities in order to produce Finishing work for insulating walls from the inside. Therefore, such work often has to be done at night. When insulating walls warehouse still needs to be taken into account important nuance: many works will have to be done at height, so additional equipment will be required in the form of a tour - a mobile tower or convenient stairs.

The main types of warehouse insulation materials most often used are the following:
- mineral wool;
— sprayed polyurethane foam;
- sandwich panels;
- Styrofoam.
Each of these insulation materials has its own advantages and disadvantages. Therefore, they should be considered separately.

1. Mineral wool: is in the classic way insulation of warehouse premises. This method of insulation is cheap. In addition, mineral wool fireproof, which is very important for such premises. But it also has its drawbacks. For example, it can absorb moisture. In addition, it has a decent weight for insulation, which can be dangerous for thin walls made of galvanized steel.

2. Spray polyurethane foam has become very popular lately. It is able to seal all cracks, is not afraid of fire, and has low thermal conductivity. It is very easy and quick to apply to walls. But its disadvantage is its high cost. And the warehouse must be stopped during such insulation.

3. Sandwich panels are very beautiful and quite durable. Their advantage is that they do not require further finishing. But the disadvantages of such insulation include the labor intensity of the work and their decent weight. This means that the load not only on the walls, but also on the foundation will increase significantly.

4. Polystyrene foam is the cheapest insulation material. Once the walls are insulated, the warehouse won’t even need to be shut down. It also differs in that it is very light. But it also has disadvantages: rodents love it and it is a highly flammable material.

Therefore, how to insulate your warehouse is up to its owner to decide. In this case, it is necessary to take into account its size and what material it is built from.

Antipyretics for children are prescribed by a pediatrician. But there are emergency situations with fever when the child needs to be given medicine immediately. Then the parents take responsibility and use antipyretic drugs. What is allowed to be given to infants? How can you lower the temperature in older children? What medications are the safest?

For the development of industrial production, wholesale trade, and logistics business, it always requires the presence of decent-sized warehouse space. In addition, warehouse stores and online trading platforms that do not have separate areas for selling goods are becoming more widespread.

What's the problem?

Of course, it is not particularly difficult to erect a small warehouse building from materials that already have heat-saving properties. But if we are talking about areas and volumes for organizing the storage of products, raw materials or goods, amounting to hundreds and thousands of square and cubic meters, then traditional construction methods will not be economically justified.

Hangars and warehouses of large areas are most often built using frame technology or using prefabricated structures. An example is the well-known arched metal structures assembled from wave-shaped steel sections.

The steel sections do not retain heat at all in winter and do not protect the internal volume from heating in the sun in summer. There are also warehouse structures made of concrete slabs, which also require thermal insulation. What methods and materials are used to improve hangars and other large premises?

Methods for insulating structures made of metal and concrete

Among the variety of methods for preserving heat in a warehouse, several basic ones that are acceptable in terms of efficiency deserve attention.

Method 1: Creating an Inner Outline

The method of insulation by building an internal contour consists of erecting a lightweight, insulated, non-load-bearing frame structure inside the hangar.

Installation can be carried out using various technologies - using wooden slatted or metal profile frames with the installation of foam or slab insulation in them and then cladding them with panels.

Significant disadvantages of the method are the reduction in the usable area of ​​the warehouse and the high cost of the structure.

Method 2: insulation with basalt and glass wool slabs

Insulation with slab, basalt or glass wool material as a method is effective in terms of heat conservation, but is inconvenient to implement. Essentially, this is the same option as with an internal contour, but the frame is mounted directly on the walls of the warehouse.

This places additional stress on the hangar sections and may affect its stability. In addition, it may be difficult to attach slats or profiles to steel walls. Another disadvantage of this method is that moisture inevitably accumulates in the thickness of the insulation and does not escape.

Method 3: foam as insulation

Polyurethane foam insulation has become popular. This material exists in two forms - in the form of slabs and in the form of a liquid mixture, which foams on its own after application. Plates are used to insulate the external surfaces of wooden or concrete walls, and foam is used to treat interior walls. Liquid polyurethane is probably the most suitable insulation for steel structures.

Construction foam has good adhesion to any surface. Its thermal conductivity properties do not depend on the shape of the walls, and the degree of insulation can be adjusted by the thickness of the layer. The disadvantage is the inability to process at subzero air and wall temperatures.

Materials: properties and comparison

Let's consider several main characteristics that are essential specifically for insulation of warehouses and hangars:

• thermal conductivity, i.e. the degree of insulation of a layer of a certain thickness;
• flammability or ability to sustain combustion. The fire protection of premises depends on this parameter;
• specific gravity or the load that the building structure will bear due to insulation.

This insulator has the following characteristics:

• specific thermal conductivity: about 0.030 W/m*K. This figure characterizes both glass wool and basalt materials;
• flammability: do not burn and do not support combustion. Glass wool slabs can withstand temperatures up to 400°C without loss of properties, and basalt fiber slabs can withstand temperatures up to 1000°C. The walls of a warehouse covered with basalt fiber can withstand open fire for a long time;
• specific gravity: depends on the density of the slab and ranges from 35 kg/m3 to 180 kg/m3. To insulate a steel wall, a 15 cm layer with a density of 100 kg/m3 is sufficient. Thus, for an area of ​​1 m2 the load will be 15 kg.

Polystyrene foam and polystyrene foam

Polystyrene foam or expanded polystyrene in solid, slab form have the following qualities:

• thermal conductivity: for foam plastic - 0.037 kg/m3, for expanded polystyrene - 0.027 kg/m3, which is quite comparable to the characteristics of mineral wool;
• degree of flammability: polystyrene foam and expanded polystyrene can burn, however, in modern production, fire retardants are added to them, which allows these materials to be assigned a flammability class of G1 and called non-flammable. The heat resistance of foam materials is low - they cannot withstand heating even up to 250-270°C, and when burned they emit gases that are dangerous to humans;
• specific gravity: polystyrene foam - 100 kg/m3, polystyrene foam - 40 kg/m3, polyurethane foam (spray foam) - 40-80 kg/m3. 1 m2 of polystyrene foam with a layer of 15 cm will weigh 15 kg, polystyrene foam - only 6 kg, and polyurethane foam - from 6 to 12 kg.

Insulation materials such as polyurethane or construction foam have the same characteristics as slab polyurethane foam materials.

Comparative analysis

A basic comparison of characteristics shows that the degree of insulation of all materials is almost the same; polystyrene foam and polyurethane foam have the minimum weight. Moreover, the calculation did not include the weight of the frame structure, which is necessary if mineral wool or hard foam material is used. The safest way to protect against fire is to use stone wool. However, liquid polyurethane is the easiest to install.

Another important characteristic is the cost of materials. The most expensive are stone wool insulation, the cheapest are foam boards. The choice of thermal insulation for a warehouse depends on the design features, wall material and financial capabilities.

Installation work

The technology of insulation with fibrous and slab materials can be described in the following steps.

The frame is assembled from wooden slats (usually for foam) or metal profiles.

The frame is fastened to the walls either with self-tapping screws or with dowels; metal profiles can be secured to steel structures using wire and welding. The thickness of the frame elements must correspond to the thickness of the insulation sheets.

To prevent the accumulation of moisture inside the mineral wool layers, it is advisable to place a vapor barrier on both sides, and if the installation is carried out outside the walls, a windproof, vapor-permeable membrane. The films should be secured with slack so that thermal fluctuations in the dimensions of the hangar structures do not damage them.

The frame is usually located inside the building. However, to preserve useful volumes, it is possible to insulate from the outside, followed by cladding.

Laying slabs

Plates, sheets or rolls are laid between slats or frame profiles and secured. Possible joints are carefully sealed with scraps of the same material or polyurethane foam.

Facing

This is carried out not only to make the appearance more presentable, but also to prevent damage to the insulation. Another technology is used to apply a layer of polyurethane to the walls. The liquid composition is applied by spraying from special sprayers. Work must be carried out in protective clothing, and ventilation must be provided in the room.

After application, the composition expands on its own for some time and fills all the unevenness and cracks in the walls. The hardening time is about 1 hour. The result is a textured surface that can subsequently be painted with water-based paints.

Insulation various types hangars with sprayed polyurethane foam in the agricultural complex

In this article we will try to substantiate the thesis stating that today one of the most effective, inexpensive and fastest methods of thermal insulation of large non-residential premises is insulation with sprayed polyurethane foam density PPU from 45-60kg/m3 on a freon basis.

Probably, it will not be a revelation to anyone to say that a building of enormous area and height, which does not have high-quality thermal insulation, is capable of bankrupting its owner in one winter due to astronomical heating costs. You don’t need to have knowledge of higher mathematics to calculate how much it will cost to heat volumes measured in tens of thousands of cubic meters.

If such a structure is not located in the subtropical climate zone and the average winter temperature outside its walls fluctuates below zero on the thermometer scale, the only solution to the problem of maintaining the required temperature inside is high-quality thermal insulation. No one will argue with this axiomatic statement. Another question is the choice of the type of thermal insulation and the material on the basis of which it will be implemented. Let's produce brief analysis main heat-insulating materials and impartially compare their advantages and disadvantages.

The main types of thermal insulation materials for hangar insulation

First of all, it should be noted that all thermal insulation materials are divided into two main groups - inorganic and organic.

Inorganic thermal insulation materials

The most common inorganic thermal insulation materials include the following:

mineral wool;

glass fiber (glass wool);

foam glass.

We will not go into the intricacies of the production technology of these materials, since this is of little interest to the end user. Let's dwell on their properties.

All of the above materials are characterized by fire resistance, low thermal conductivity and resistance to chemical and biological influences (mold, pests). However, despite the above-mentioned advantages, they also have a number of serious disadvantages. Mineral wool And fiberglass They are characterized by high hygroscopicity, which leads to the fact that these thermal insulation materials become completely unusable after just a few years, if they are not impregnated with special hydrophobizing (giving water-repellent properties) compounds, and mineral wool also requires mandatory waterproofing.

The above-mentioned disadvantages are devoid of such insulation like foam glass, however, it has high rigidity, which limits its use in conditions where the surface has a complex shape.

For the most part, the above-mentioned insulation materials are supplied in the form of blocks, which are fixed using fasteners of one type or another on the walls of the room to be insulated. This inevitably leads to damage to the integrity of the structure, which, in turn, reduces its service life to a greater or lesser extent. It is also possible to fasten these materials with glue, but this method also has its drawbacks: the glue does not hold so firmly, and as a result of temperature changes, peeling of certain sections of the insulation may occur. With both fastening methods, due to the fact that the heat-insulating coating is not monolithic, so-called cold bridges will inevitably occur, reducing the overall effectiveness of the heat-insulating layer.

You can also mention in this section such a material as foam concrete, which is not just T heat-insulating material, but a building material with low thermal conductivity. But this is still a building material, not insulation.

Organic thermal insulation materials

The most common organic thermal insulation materials include the following:

polystyrene or Styrofoam;

polyethylene foam;

polyurethane foam.

We have all been familiar with the first type of the above-mentioned organic insulation since childhood: who among us has not annoyed our beloved parents by driving a piece foam plastic on glass? This lightweight material consists of 90% air, and air is known to be a good heat insulator. Insulation with expanded polystyrene has been widely used for a long time, but this material has one significant drawback - it is very fragile.

Polyethylene foam- one of the most promising modern materials, which has almost all the advantages of polyurethane foam, which will be discussed a little below. But it also has a significant drawback - like any polyethylene, it is not heat-resistant.

Now let's move on to considering the properties of polyurethane foam - a material that combines all positive traits the above-mentioned heat insulators and practically free of their disadvantages.

One of the main advantages of polyurethane foam is the ability to be sprayed onto a surface of any size and shape, resulting in a uniform layer of thermal insulation without any joints or gaps. The result is a complete absence of cold bridges.

Due to the fact that polyurethane foam has exceptionally high adhesion to surfaces of almost any type, the possibility of peeling off the heat-insulating layer is completely eliminated. In addition, spraying technology significantly reduces the time required for insulation of various buildings.

Polyurethane foam very effective and lightweight: a ten-centimeter layer of this substance is equivalent in its thermal insulating properties brickwork two and a half meters thick. The lightness of the material in question is due to the fact that it consists of 85% - 97% (depending on density) of air or gases.

Polyurethane foam is heat-resistant and frost-resistant, which allows it to be used in all climatic zones. It does not require any additional waterproofing, and even moreover, its rigid version can itself serve as an excellent waterproofing agent and is widely used in construction as such.

Another advantage of this material includes excellent noise insulation properties.

Taking into account all of the above, we can safely say that polyurethane foam is most suitable for insulating metal structures such as hangars. The lightness of polyurethane foam makes it possible not to overload the structure made of a metal sheet slightly more than 1 mm thick; heat resistance will be needed in the hot summer months when metal heats up to very high temperatures; frost resistance allows you not to worry about the strength of the thermal insulation layer even in severe frosts, and the absence of cracks ensures that not a single drop of precious heat leaks out. If we add to this the speed with which polyurethane foam insulation is carried out, it becomes clear that prefabricated hangars and this insulation are simply made for each other.

Insulating a polyurethane foam warehouse is beneficial

Many shopping complexes, manufacturing companies, shops and firms require their own warehouse space. The key task of such structures is to ensure proper storage conditions various cargoes. The storage area must comply established standards storage to avoid damage to the cargo and changes in its parameters. Maintaining a certain temperature and humidity conditions in a warehouse is a top priority for every business owner. An uninsulated warehouse leads to a lot of trouble. The problem of maintaining the required temperature arises, as a result of which the storage conditions of goods are violated and the work of equipment and people is hampered. Condensation forms, leading to rust on equipment, rotting of ceilings and dampness of stored products. As a result, electricity costs increase and company losses increase. This kind of consequences can only be avoided through competent means.

Insulating a warehouse with polyurethane foam effectively solves a number of problems. This option is rightfully considered one of the best from a technological and economic standpoint. Sprayed polyurethane foam has a mass positive aspects, which sets it apart from other outdated alternatives: polystyrene foam, fiberglass, basalt wool slabs.

Warehouse before and after applying polyurethane foam

Insulating a warehouse is a rather complex and costly process. The complexity of thermal insulation of warehouses is due to their design features. Typically, such structures are based on prefabricated frame structures with an arched dome shape. Standard methods of thermal insulation of a room, applicable for residential buildings, are unprofitable here. In many cases, they do not achieve the desired result. Highly effective people come to the rescue modern techniques– insulation of the warehouse with polyurethane foam.

Insulating warehouses using the indicated method provides many advantages. The material is easy to apply. The composition, the components of which are liquid polyol and isocyanate, is sprayed onto the surface under high pressure. When applied, it increases in volume many times over and hardens almost instantly. Therefore, insulation of large warehouses can be done in a day with just two people. The material has the lowest thermal conductivity coefficient in comparison with other building materials - 0.019 W/M*K.

Polyurethane foam can be applied to surfaces made of iron, concrete, and brick that have not been previously prepared. A frame is not required for this, nor is the use of special fasteners. The shape of such surfaces does not matter - the material fits perfectly into all the recesses, filling them with itself. The complex geometry of a warehouse will not be a problem for this polymer. It fits snugly to all surface irregularities.

Insulating a polyurethane foam warehouse is beneficial from an economic point of view due to the fact that the material minimizes heat loss and energy consumption. The resulting coating has no seams, gaps, or joints. The polymer layer is equivalent to 500 mm thick brickwork. At the same time, for insulation of warehouses, a coating with a thickness of 50-80 mm is quite sufficient. This ensures savings in usable space required for storing products, cargo, etc.

The advantages of polyurethane foam are obvious:

It is not afraid of moisture, which eliminates the need for waterproofing.

Incombustible. The material is not flammable and does not support combustion. Garage insulation with polyurethane foam provides fire safety designs.

Capable of effectively filling all existing voids.

Provides good sound insulation.

Protects metal structure garage from the emergence and spread of corrosion processes.

Thermal insulation is completely moisture-proof, there is no formation of gas condensation, the development of fungus and plaque. The low density of the material leads to a decrease in the overall load on bearing structures. The cellular structure of the material ensures proper vapor permeability of the heat insulator. This guarantees the absence of dampness and mold, which is especially important during storage. food products in stock.

Polyurethane foam does not react with water and chemicals. Excellent adhesion of the polymer ensures an excellent connection between the heat insulator and any type of wall.

PUF is environmentally friendly and safe for health. Its composition does not contain harmful impurities. It can be freely used for insulating food warehouses. It is resistant to combustion and temperature changes, and successfully copes with both frost and heat. The flammability class of the material ГЗ guarantees that it is not capable of becoming a source of fire and does not support the combustion process. The created thermal insulation can last 30-50 years without any repairs.

This material organically combines excellent heat, noise and waterproofing. Insulation of PPU warehouse – great way provide high-quality thermal insulation of this type industrial facilities at maximum speed carrying out work over large areas.

If you are running a business, then it is not for us to tell you how important the reliability of warehouse facilities is. Just imagine that there was a frost and all your goods suffered from it. Such situations must be thought through in advance. This will avoid losses.

Insulation of warehouses will help preserve the presentation of your products all year round. This procedure also allows you to save money, since after thermal insulation you will be able to heat your warehouse less intensively than before. After all, insulated walls retain heat inside the room.

What material should you choose for thermal insulation of a warehouse?

If you decide to insulate your warehouse, then it is best to choose polyurethane foam for these purposes. It has a lot of advantages:

Easy to install. Insulation work using this material will take no more than 1 day. Agree that such terms are quite attractive;

Saving. In addition to the fact that your goods will always be safe, you can save on heating. Insulating warehouses with polyurethane foam reduces energy costs by 50%. A one-time investment in insulation will help you save for years to come;

Durability. Polyurethane foam as insulation can last for several decades.

Warehouses are designed to store various materials and goods. Often, the storage of certain groups of goods requires special conditions, including a certain temperature, humidity, and generally microclimate. To create these conditions, the room must be insulated as much as possible from the influence of external environmental conditions, that is, sealed and thermally insulated. In cold climates, house facades are not able to retain heat indoors on their own. The result is high heating costs, the low efficiency of which is due to the high thermal conductivity of building materials.

POLYURETHANE FOAM – THE BEST SOLUTION FOR WAREHOUSES

Today, for thermal insulation of premises of any type, many modern insulation materials are used, which are designed to solve various problems. However, polyurethane foam, or PPU, is best suited for insulating warehouses. This heat insulator has unique characteristics that are still unattainable for other materials. In particular, polyurethane foam has the lowest thermal conductivity coefficient, which allows you to recoup investments in thermal insulation in just two seasons, and subsequently save up to 50% on energy resources for a long time.

PROPERTIES OF POLYURETHANE FOAM, SO NECESSARY WHEN INSULATING A WAREHOUSE

The only drawback of polyurethane foam is its exposure to ultraviolet rays. However, this problem can be solved by simply painting the thermal insulation with any paint that will protect the surface.

Naturally, it is impossible to create the necessary microclimate in the warehouse only by thermal insulation of the room. Therefore, in combination with insulation, it is necessary to take care of high-quality, well-designed ventilation. This complex will help make your warehouse an ideal place to store any goods.

Print

In many regions, insulated warehouses are needed to store products. They allow you to store products that require certain climatic requirements. Thanks to the presence of such premises, all work related to long-term storage of agricultural products can be carried out even in severe frosts. Therefore, when designing a building, it is necessary to consider high-quality insulation warehouse This can be done in several ways: choose a two-layer hangar design from metal profile or sheathe the structure with one of the insulating materials. Each option has its own advantages and disadvantages, so they must be taken into account when constructing the structure.

To keep products in stock, the following conditions must be met:

• sufficient air conditioning of the room;
• stable temperature maintenance;
• lack of conditions for the development of pathogenic bacteria.

Reliable insulation of the warehouse will help achieve this. The following materials can be used for this: polyurethane foam and tepofol. The technology of constructing an arched hangar in the form of sandwich panels can also be used. Each of the materials used is modern, but has a number of features.

Polyurethane foam

Foamed polyurethane insulation is considered a reliable and time-tested material. His main feature– it can be applied both to the outside of the structure and to the inside. Reliable treatment of walls with such insulation allows you to protect the warehouse from hypothermia and dampness, and prevent overheating of the structure. Due to the characteristics of spraying, it can be applied to any type of surface.

Advantages of PPU

Among the main advantages of insulation it is worth noting the following:

• affordable price in comparison with similar types of insulation;
• high degree thermal insulation;
• waterproofing;
• sound insulation;
• aesthetically attractive appearance;
• the ability to perform any interior decoration;
• durability of the material (up to 30 years of service);
• absence of joints and seams;
• safety for humans and food products stored;
• no weighting for the structure;
• Increased elasticity of the material prevents deformation of the hangar.

It not only protects the room from the cold, but also prevents the structure from overheating. Sheathing with polyurethane is not only fast, but also cost-effective.

Flaws

Among the disadvantages, one can highlight the need to use special equipment for applying sprayed polyurethane foam. At the same time, no work can be carried out in the hangar at the time of installation work.

Violation of the technology for laying polyurethane foam can lead to the appearance of moisture between the wall and the insulation. Over time, this can provoke the destruction of the wall and, accordingly, the entire structure.

Tepofol

Tepofol thermal insulator is available in various types. There are two key categories:

• coated with foil;
• with metallized coating.

This modern insulation with many useful characteristics. Its structure resembles foamed polyethylene. Its thickness can vary from 2 to 10 mm.

Advantages

The insulation has the following positive features:

• environmental safety due to the absence of harmful fumes;
• lightness of the material;
• reflectivity reaching 97%;
• resistance to rotting, mold and harmful fungus;
• no threat from rodents and insects.

Thanks to its porous structure, the material absorbs sounds, while the surface “breathes”.

The foil version of tepofol has the following advantages:

• preservation of the original form;
• mechanical strength;
• hydrophobicity;
• safety for human health;
• good noise absorption;
• long service life;
• resistance to corrosion damage;
• ease of installation.

Also distinguish the following types insulation:

1. Tepofol type A is available in a roll consisting of a one-sided coating of metallized film. Perfect for insulating ceilings, walls and pitched roofs. It is perfect for thermal insulation of pipelines.
2. Tepofol type B consists of a double-sided reflective aluminum foil and foamed polyethylene between layers. It is this structure that completely eliminates all types of heat loss: from thermal radiation to convection.
3. Tepofol type C consists of 4 layers: metallized film, polyethylene foam, adhesive layer and protective film. It protects against moisture and noise and does not require additional styling vapor barrier material.

Any type of tepofol can be used in regions with temperatures from -60 to +100 degrees.

Flaws

The disadvantage of insulation is its vulnerability to mechanical damage. Even minor damage to the film can lead to rupture of the entire layer. In this case, a complete replacement of the material will be required.

Double layer hangar

The best option is to build an insulated hangar for a warehouse. This design is reminiscent of sandwich panels: two sets of arches are erected, one above the other, and insulation material is placed between them.

Advantages

The advantages of a two-layer hangar are:

• higher degree of protection from winds and frost;
• fire safety;
• protection of insulating material both outside and inside;
• the ability to choose colors for arches;
• variety of material filling the space between the arches.

Foamed polyurethane, mineral wool and expanded polystyrene are suitable for insulating a warehouse of this type.

Flaws

The main disadvantage of this option for warehouse insulation is the high cost of the structure. In fact, instead of one, two almost identical hangars are being built.

It is also worth noting that violation of installation technology can lead to icing in winter. Mechanical damage to the insulating material will require dismantling and complete replacement insulation. If there is no possibility of heat exchange, condensation may occur.

And if the slab exceeds the length of 7 m, it will not be able to withstand the additional load.

Warehouse floor insulation

For reliable protection To protect against cold and frost, care should be taken to ensure reliable insulation of the warehouse floor. It can reduce the amount of heat loss, maintain the temperature at the required level, improve the soundproofing characteristics of the warehouse, and also avoid drafts and humidity.

Most often in such arched hangars the floor is concrete. Therefore, insulation is carried out with foam plastic or penoplex. During the construction process, these works involve the following sequence:

1. Clearing the area from construction waste, dust and dirt.
2. Leveling the ground. Sand can be used if necessary.
3. Laying insulation boards and securing them.
4. Creating a frame from reinforcement.
5. Pouring a layer of concrete.

If the floor insulation is carried out after completion construction work, such manipulation will require large financial investments, since the layers will be laid anew. At the same time, in places where transport (forklifts or cars) will operate, additional concrete flooring will be required.

Sheet insulation is considered the best option for insulating warehouse floors. They are denser and create an additional basis for the reinforcement frame. Used for these purposes.
