Insulating walls with foam chips reviews. Insulation with foam ball

Lightweight, spherical polymer granules foamed with isopentane gas or produced from residual parts of expanded polystyrene are called foam chips. It is durable and environmentally friendly pure material, which has found wide application in the construction and repair industry.

Properties and characteristics

Expanded polystyrene chips have the following properties:

• thermal insulation (complete filling of the air cushion with small granules in the insulated area removes any cold bridges);
• sound insulation (granules have a rough surface that does not conduct sound vibrations well);
• environmental friendliness (the material is non-toxic and safe for people);
• shock-absorbing abilities (when squeezed, the balls do not lose their structure and quickly take their previous shape);
• performance characteristics (operating temperature range from -190°C to +87°C);
• moisture resistance (lack of absorbent properties);
• fire resistance (granules are treated with a fire retardant substance);
• ease of operation and transportation (light weight and fills the required space as much as possible);
• has no odor and does not cause allergic reactions;
• profitability (relatively low prices for the product and the possibility of reducing prices for other materials by mixing solutions with foam chips).

However, there are a number of restrictions on working with raw materials. Avoid exposing it to a direct open source of fire and do not add it to hot asphalt. Also, if dichloroethane, acetone, benzenes, ketones or their vapors contained in some varnishes and paints come into contact with the material, it is destroyed and almost completely loses its properties. Therefore, it is necessary to strictly follow instructions and safety precautions when working with granules.

Varieties and applications

Foamed polystyrene foam granules have a smooth spherical surface white with a diameter of 1 - 8 mm, which does not deform when compressed.

Granulated polystyrene foam is produced by heating glassy PS beads at temperatures above 80°C and subjecting them to isopentane vapor pressure, which expands the polystyrene into a granule. After this, they are dried and cooled. Such balls become very dense and elastic, which allows them to withstand heavy loads and also be used in the temperature range from -65°C to +75°C.

Due to many specific properties, this material is widely used in industry. Insulation with foam chips is considered the most reliable cold-resistant method of thermal insulation of floors, walls or roofs. In addition, it is added to building mixtures and solutions for the purpose of lightening and insulation. Granular foam is used as a filler for upholstered furniture or children's toys, as bulk packaging material, in the production of polystyrene concrete and as a filter component in water purification. The balls are also used as bait when fishing, to lighten structures in unmanned aerial vehicles and when lifting sunken ships.

Varieties of granules differ in physical and mechanical characteristics. Important indicators The durability of expanded polystyrene foam are:

• dimensions that comply with standards (the granule diameter must be from 1 to 8 mm, and maximum deviations in linear dimensions must be less than 0.5mm);
• coverage density of the space being filled (from 8 to 30 kg/m 3);
• correct geometric shape and color (spherical white balls);
• compressive strength with a low probability of deformation (0.005 - 0.026 kg/cm2);
• low thermal conductivity of dry granules at a temperature of 25°C (0.053 - 0.036 W/mxK).

The product is packaged in plastic bags with a volume of 0.25 - 1 m 3.

The price of foam chips ranges from 1270 to 1400 rubles/m3.

Characteristics and application of "Crushed"

Foam chips "Droblenka" are polymerized round crushed balls with a diameter of 2 - 7 mm, which are produced from recycled (crushed) PS waste. This manufacturing method helps reduce the cost of this material with partial loss of its primary shape in the foam. However, other original properties are preserved during the crushing process.

“Crushed” expanded polystyrene is used as a moisture-resistant, heat- and sound-insulating building material. The insulation made from foam chips is of high quality and inexpensive.

In addition, crushed polystyrene foam is used:

• insulating foundation slabs and walls;
• in the production of polystyrene concrete;
• in the form of shock-absorbing bedding;
• for device roofing coverings With flat slope;
• for mixtures with concrete or cement with foam chips;
• for thermal insulation of trench pipes;
• for the manufacture of cement-sand screed;
• as the best backfill material for walls with an air gap.

The technical characteristics of crushed foam plastic should approximately correspond to the parameters of granular PS. At the same time, the distinctive indicators of the quality of “Droblenka” are the absence of large parts of uncrushed foam in the material and the low number of deformed elements.

The product is packaged in plastic bags of 0.5 and 1m3.

Prices for crushed polystyrene foam are several times lower than for granulated polystyrene and range from 150 to 250 rubles/m3.

Application of foam chips

Application can be carried out in several ways: by backfilling, laying or blowing.

• The backfilling process is quite simple. Hollow spaces in inter-wall ceilings, cavities in walls, uneven surfaces, underground space, the attics are filled with balls in an amount sufficient to level or fill the required space;
• The laying technique is carried out using foam concrete made from a mixture of cement and crumbs. To obtain the laying material, 60 kg of sand-cement mixture, 0.5 liters of plasticizer, 60 liters of granules and 8 liters of water are poured into a compact concrete mixer. Then everything is mixed. However, the solution must be made sufficiently viscous, since the balls may float to the surface while laying the screed;
• screed with foam chips is performed in two stages. First, the first half of the screed (rough) is poured, and after it dries and hardens, the second half (finish). The screed is periodically moistened to avoid cracking and low surface strength. So after final stage works, the floor structure with foam chips becomes insulated, lightweight, moisture-resistant, and fire-resistant;
• blowing is carried out using a specialized blower. This technology allows you to completely fill any void structures. Under the influence of air flow, balls with a diameter of less than 8 mm fill all irregularities and crevices in an even layer.

The homogeneity, softness and elasticity of foam balls means that they can take any shape of the space being filled. They are an excellent substitute for others traditional insulation(expanded clay, foam plastic, mineral wool), since they do not completely fill the required space and over time move away from the insulated surface, which can lead to the appearance of a dew point or cold bridges, and then to destruction wooden elements the buildings.

Thus, the foam chips become the best solution when choosing insulating, fireproof, high-quality and economical material among most traditional substitutes.

Foam chips are polymerized round balls with a diameter of 3 to 7 mm. Crushed foam plastic (so often called this type crumbs) is obtained by industrial crushing of foam production waste. Economically, this method is more effective, since thanks to this method of processing foam, it becomes cheaper as a primary material, and the original properties of the foam when crushed remain the same.

Application of foam chips:

Expanded polystyrene chips have found wide application in the industrial, construction and repair sectors. Crushed foam is mainly used as a building material and excellent insulation. Insulation with foam chips is considered the most economical and reliable method for thermal insulation of foundations, floors, walls or roofs. Let's consider the basic principles and methods of use:

• Filler: foam chips are used to fill holes and cavities in ceilings between walls, into brickwork or to level surfaces. Due to their technical characteristics, foam granules can take any shape, which avoids any cold bridges. High strength allows you to avoid deformations, unlike insulation materials such as expanded clay and mineral wool.
• Floor screed with foam chips: the process of preparing polystyrene concrete takes place in several stages. Initially, prepare the solution: take a small amount of water and cement, mix until a creamy consistency is obtained. The second stage: while continuing to mix the solution in a concrete mixer, add crushed foam. The ratio of the material depends on the expected result of thermal insulation. The higher the percentage of foam granules, the greater thermal insulation properties your screed. However, the following must be taken into account: if the material is distributed incorrectly, the density may decrease. For example, if you plan to use linoleum on the floor, the percentage of foam granules used should be less than when laying parquet.

If you yourself want to make a floor screed with foam chips at home, then to obtain the solution you must observe the following proportion (*builders’ recommendations):

• 4-5 buckets of expanded polystyrene crumbs
• 2 buckets of sand
• 1 bucket of cement
• 1 bucket of water

It is important to note that when working with expanded polystyrene crumbs, it is necessary to adhere to the standards of use and observe safety precautions: avoid open flames, do not use various chemical solutions.

Styrofoam crumbs - efficient material for insulation of concrete floors, will last a very long time and will not lose its operational properties. Comfort and warmth guaranteed!

Int-Deco offers to buy foam chips in Kyiv or with delivery throughout Ukraine. Crushed polystyrene foam is packed in polyethylene bags of 0.33 m3 each.

Foam chips for insulation

One of the most popular materials for insulation can be considered foam chips. The choice of consumers is justified, since this is a high-quality, environmentally friendly material that will help make the house warm and comfortable without significant damage to family budget.

Foam chips properties and applications

Foam chips have a number of advantages compared to other thermal insulation materials.

Foam chips - what is it?

Foam chips or granules are bulk material, which is noted for its versatility and is made of foam balls with a diameter of approximately 5-6 mm.

Characteristics and properties of foam chips

Polystyrene foam granules have all the properties of a solid sheet, but unlike foam plastic boards, granules can take the shape of any container where they are placed. Expanded polystyrene granules have a number of features:

1 Almost does not conduct heat. Polystyrene foam tens of times exceeds the thermal insulation of conventional concrete and almost ten times ceramic bricks.

2 Safe for people, does not contain toxic substances, does not cause allergic reactions, odorless, no organisms live in it.

3 Light weight. For comparison, 1 cubic meter of foam chips weighs about 15 kg, and plywood weighs about 500 kg.

4 Wear resistance. Data from laboratories that test expanded polystyrene will determine the durability of the material - approximately 80 years.

5 Very resistant to temperature changes and can withstand changes from -170 to +90.

6 Sound insulation due to the elasticity of granules and cellular structure, which reduce sound vibrations.

7 Ability to restore the original shape during deformation.

8 Ensuring air exchange of the surrounding space, i.e. Unlike regular polystyrene foam, the granules are able to “breathe”. This prevents Greenhouse effect and future mold formation.

Foam chips are characterized by the following criteria

1 Density of the material from which the balls are made. The high density of the substance determines the increase in the mass and strength of the granule.

2 The diameter of the granules can be varied from 1 to 8 mm by specifying right size when crushing.

3 Flammability. That is why this material is used in inner layers walls To increase fire resistance, fire retardant is added to the foam. After this, the material becomes self-extinguishing.

Pros of foam chips

All materials have their advantages and disadvantages. Foam granules are no exception.

The following advantages can be highlighted in using foam chips:

Less weight of the final structure.

Savings on future finishing materials due to heat and soundproofing properties.

Simplicity in operation.

Low cost.

Disadvantages of using foam chips

The soft structure of the foam makes the screed made from such a solution not so wear-resistant.

The need to isolate from air due to its flammability. Foam concrete is capable of rapid destruction if it comes into contact with air.

Types of foam chips

There are two ways to obtain polystyrene foam granules and, accordingly, two types of them:

Primary processing, when special technology is used to foam polystyrene beads. This is an expensive process.

Crushing foam waste. This is a secondary production, so it is more economical. The remaining foam is placed in special machines that crush the material until homogeneous. If necessary, you can set the desired ball diameter.

Cost of foam granules

The efficiency of foam chips was noted as quality material for insulation compared to others. Depending on the characteristics of the foam granules and the method of their production, the price per cubic meter can vary significantly. The smaller the diameter of the granule, the higher its price. Foam chips obtained by crushing are much cheaper than those obtained by primary foaming.

Application of foam granules in various fields

Foam chips are used to insulate attics, walls, floors and floors.

1 Insulation of the attic. A room loses a significant percentage of heat through the roof. Foam granules great option insulation of the attic due to the low degree of moisture absorption and resistance to temperature changes.

2 Wall insulation. In addition to the main characteristics, foam chips take the shape of the container in which they are located, this is especially important when insulating a facade with shaped elements.

3 Insulation interfloor ceilings. Sound insulation and the specific weight of the final structure are important when forming and insulating interfloor floors. Foam chips are also useful for floor insulation if there is a basement under the house that is not heated and is required additional insulation.

Brief summary

Consumer interest in foam granules is justified by its versatility and low price. Due to its unique properties, foam chips are in demand in many areas from construction and furniture making to the creative process design decorations and fishing.

The cost of foam granules depends on technical characteristics the granules themselves and the method of their production.

Leveling the ceiling using “warm” plaster based on polystyrene foam chips

Leveling the ceiling by applying thick layers of plaster is not always justified: you will need to attach a reinforcing mesh, and if significant difference ceiling level - the layer will not withstand and will collapse. Adding polystyrene foam balls to the plaster will help you in this case, as well as when repairing walls, masonry in a well, joints of external panels of a house and internal slabs ceilings, attics, roofs and floors. When connecting polystyrene foam balls with cement-sand or concrete mortar, ready mix Excellent heat retention indoors.

To work with the ceiling, we will need the same tools as for regular plastering and at least two plastic buckets.

After cleaning the ceiling from old layers, carefully prime the ceiling using a “fur” roller. For concrete slabs“Betonokontakt” primer is suitable. Complex and hard to reach places prepare the ceiling several times with a brush.

The drying time of the primer is indicated on the packaging - from different manufacturers different time from 3 to 8 hours. Experienced craftsmen They never follow the recommendations for hardening, but try the surface by touch. If the ceiling is still damp, then you should wait, otherwise leveling the ceiling will be in vain - the further layer will collapse in a few weeks.

Polymeric plaster mortar prepared from Styrobond glue in a 1:1 ratio to M400 cement in a bucket. Mix everything with a drill and a mixing attachment until the mixture is homogeneous, gradually adding water until it becomes “sour cream” thick. If the mixture seems too thick, you can add a little water to it.

Now we add polystyrene foam, and you have 2 options: use ready-made crumbs, which are sold in construction stores by weight, or take a regular foam board and crumble it over a bucket. Fill a separate clean bucket 75% full, then add half of the glue solution you just prepared from the first bucket. The proportion of crumb solution will be somewhere around 1:2.5. Mix the composition until all polystyrene foam granules are colored dark color.

If your screed (cement + sand) is too high, then it is better to avoid unnecessary overloading of the floor slabs and use a lighter material - expanded polystyrene concrete. Its composition is simple: cement not lower than M400, polystyrene foam balls and foaming agent “Saponified wood resin” (SDO). Leveling the ceiling with expanded polystyrene concrete makes the layer not only light and warm, but also not subject to shrinkage and cracks.

Table 1. Methods for manufacturing expanded polystyrene concrete

Description	Advantages	Flaws
“Encapsulation” when it is necessary to reduce the density of the material. The granules are covered with cement glue, and the voids are not filled with sand. No special equipment and chemicals It is impossible to prepare such a mixture with additives!	Possibility of producing PS concrete with a density less than 200 kg/m3, using granules of the same size	The mixture delaminates when pressurized or transported, low bending strength (in case of a block)
“Porization” of the solution, which means replacing sand with air granules	Possibility of producing PS concrete whose density is less than 300 kg/m3, and changing this indicator in a wide range	It is quite difficult to obtain a stable characteristic due to the complexity technological process: bubbles are lost when stacked, transported or pressurized
Creation of PS concrete with a high-density structure that will not allow water to pass through even at a pressure of 2 MPa	All the advantages of method 2 + stability and preservation of its characteristics during transportation and spraying. Products are even formed from such PS concrete using a 3D vibrating press.	Special equipment is required

Leveling the ceiling with plaster and polystyrene foam requires the presence of SDO in the form of a powder or solution, but if you don’t find it in your store, then you can do without it. A screed without SDO will not be as warm and light as with this additive, but it is better than a regular screed made of cement and sand.

We apply plaster to the prepared ceiling in two passes. The first stage is a layer of 1 bucket (thickness up to 3 mm), then immediately apply the mixture from 2 buckets. The ironing board is constantly wetted with water. Drying time is 3 days, after which we proceed to leveling the ceiling with gypsum putty from 1 to 5 layers. Each layer must dry well before applying the next (1-3 days).

ADVANTAGES OF FOAM CHIPS

It is perfect for inter-wall ceilings and uneven surfaces in wall voids, inter-wall partitions, floors, underground, attics (on joists, boards and other materials), where it is inconvenient to lay slabs, and is also used instead of expanded clay.

High-quality foam chips have many advantages! The main advantages of the material include:
Environmentally friendly - does not contain substances harmful to humans. For example, polystyrene, from which foam granules are produced, is used to make packaging for various products and tableware.
Resistance to various atmospheric conditions - effectively protects surfaces from moisture.
Excellent thermal insulation properties - foam balls come in different diameters and shapes. As a result, it increases total area contact of foam granules with air, so the material is excellent for insulation various rooms and objects.
Excellent sound insulation - the material has excellent wave absorption properties. It is often added to cement and poured into cavities during renovation or construction.
Durability - foam granules do not change shape, physical or Chemical properties under the influence of changes in temperature or humidity.

Due to its structure and properties, foam granules are considered a reliable and inexpensive packaging material: they are actively used to protect especially fragile products.

Blowing with foam chips is one of those services that our company has been offering to its customers for several years. This is done for heat and sound insulation of residential, office and industrial premises. IN last years This method of insulating houses has gained great popularity due to the fact that there has been a steady increase in prices for public utilities, and the cost of the insulation itself is relatively low, and allows you to save a significant amount of money in the future.

This method of insulation is excellent for ceilings between walls, uneven surfaces and voids, partitions between walls, floor insulation, basements, attics, and any places where laying sheet insulation is impossible.

Insulation of a house with polystyrene foam occurs using a special industrial installation under pressure. Due to the large air flow, a foam ball of various diameters is evenly placed and compacted in the voids - almost to the density of sheet foam. Under the influence of pressure, the material clogs all the uneven walls, cracks, and potholes, thereby not giving the cold the slightest chance to penetrate the room. It is also possible to carry out pneumatic placement of such bulk materials thermal insulation materials, such as perlite, ecowool, etc.

Insulation with crumbs

Advantages of using such material:

• Insulation with crumbs gives a kind of “thermos” effect, due to which indoors comfortable temperature and the absence of its changes;
• Insulation with foam chips is much cheaper than mineral wool(by about 35-40%);
• The material itself is absolutely non-toxic to humans and does not emit harmful substances neither immediately nor after a while;
• Loose foam balls do not harbor rodents;
• It has good vapor permeability - which means that vapors freely escape outside, and the movement of air between what is inside and outside is free. This will save the walls from the appearance of such unpleasant signs of material deterioration as fungus or mold, which in itself is very harmful. That is why insulating walls with polystyrene foam will not harm the criterion.

In our country there are many private houses that were built according to the same principle - they all have a fairly wide air gap between the internal and external walls (the so-called “well” masonry). Our company will help you turn this feature of your building into its main trump card! Into the voids between the walls we blow foam chips, crushed basalt wool, perlite, etc., thus, the house is not only protected from heat loss, but also acquires additional sound insulation.

Insulation with foam chips

Insulation with foam plastic, namely blowing in inter-wall voids, occurs as follows: holes with a diameter of 35 mm are drilled in the walls (for comparison, this hole is slightly larger than a five-kopeck coin), their number can range from 5 to 10 pieces, depending on the area of ​​insulation of the wall. Very important point- the minimum layer for pneumatic laying of a foam ball should be 3 centimeters. After all the holes are made, foam balls of different calibers are blown into the cavity under strong air pressure and compacted. The procedure is repeated until all cavities are filled with material.

Insulation with foam plastic from the outside occurs in three to four hours and can be done regardless of the season. Most often, work of this kind is carried out in spring, summer or autumn, however, if necessary, we also carry out work during winter cold, there is no strict connection to the time of year.
Our company has been working in the field of thermal insulation of buildings for more than a decade. We have acquired a wealth of work experience and valuable skills. All this allows us to say that working with us is profitable, fast, and reliable!

They have firmly entered almost all areas of modern industry and National economy. Most artificially synthesized materials are widely used in construction industry as insulation.

One of the most common polymers with a wide range of uses is better known as polystyrene foam. The material is used in the form of slabs, sheets or complex structures. Small fractions of polystyrene foam – polystyrene foam chips – are also in great demand.

Due to low cost, availability and good consumer and technological qualities, the material has found many areas of application - from raw materials to creating various decor, to the base of lightweight concrete.

Production and main types

Foam chips can be obtained in two ways:

• primary. To do this, polystyrene balls are foamed using a special technology. As a result, the so-called “primary” is obtained - granules of a certain size. This technology is quite expensive and the resulting raw materials are practically not widely used in the construction industry;
• recycling. This is a secondary production method, the basis of which is pieces of foam packaging and other leftover polystyrene foam. Raw materials are placed in special devices - crushers, which crush the waste to a homogeneous fraction. The crumb diameter can be set in the machine settings. The resulting fraction is called “secondary” or “crushed”. The low cost of production has allowed this type of raw material to be widely used in many areas.

Main Applications

Foam chips, the use of which is determined by the size of the fraction and the method of production, is widespread in the construction industry.

The main use of “crushed” is the basis for lungs and. When producing polystyrene concrete, a certain amount of granules is gradually added to the solution, and the entire mixture is placed in a concrete mixer. The resulting solution is poured onto the floor, making a warm and light screed. Using a polymer concrete screed not only significantly insulates the floor, but also saves costs concrete mixture, and given the significant reduction in the total mass of the solution, the load on the foundation is reduced.

The second way to use “crushed” is pneumatic insulation. Waste is converted into liquid composition, which is pumped under slight pressure into the interwall space of houses. This method is considered the most effective when insulating old private houses.

It was these structures that were built with an additional air chamber between internal wall and outdoor. In Soviet times, this was not a tribute to fashion, but significant savings building material, since a layer of 10-15 centimeters was equivalent to another row brickwork. Unfortunately, it was almost impossible to take advantage of the full potential of the invisible layer - construction technologies of those times it was not possible to make the air chamber sealed and in winter time lost the house most heat precisely because of this design.

The insulation process itself occurs as follows:

• first, experts study the possibility of insulating a house using this method;
• then, at regular intervals, holes are drilled in the outer wall using a hammer drill;
• liquid polystyrene foam is supplied through a hose under slight pressure into the cavity, which fills the space between the walls;
• The holes are closed with special plugs.

Despite the advantages of using molten foam chips in this way, the method has some disadvantages. The most significant of them is the lack of ventilation, which leads to the accumulation of moisture in the form of condensation, gradually destroying the load-bearing structures. wooden structures Houses.

The third popular way to use crushed polystyrene foam is to fill the space between walls with dry granules during construction. without mixing with cement mortar . In the end it turns out high-quality insulation with the possibility of unobstructed ventilation. Compared to standard façade cladding foam boards, this method is much cheaper.

Additional uses of granules

Granulated polystyrene foam is used not only in construction, but also in other industries. First of all, this furniture manufacturing. There, the crumbs are used to fill frameless models of armchairs, sofas or poufs.

The next industry is the direct production of other configurations, as well as packaging materials and permanent formwork at monolithic construction. Some manufacturers use exclusively “primary”, others add some of the “crushed”.

One of the promising uses of granular foam is as an absorbent for outdoor septic tanks. Tests have shown almost complete absence of odor and higher efficiency compared to modern drugs based on bacteria.

As additional directions, granulated raw materials are used for various items decor. Synthetic snow based on foam plastic has become very popular and quite widespread. One of the hits of the last two or three years has been ball plasticine, the basis for which is fine-grained polystyrene foam and a binding gel.

Brief summary

Granulated polystyrene foam, the use of which is not limited to manufacturing polymer concrete, has become widespread in other areas due to its low cost and unique properties. Depending on the size of the fraction and the method of production, the cost cubic meter granules can vary greatly. The most expensive is the fine-grained granule"primary" polystyrene foam, and most affordable option- large “crushed”
