Insulation penofol type a foil. Foil penofol - technical characteristics of foil

Thermal insulation materials are widely used to insulate various elements of buildings. Penofol is often used as insulation. It not only helps prevent heat loss, but also reduces moisture absorption and also protects the room from noise.

Description and technical characteristics of penofol

Foil penofol refers to reflective thermal insulation. It is worth noting that all the pores of the material are closed, and there is polished foil on one side. Thanks to this, the product has increased heat saving characteristics. Separately, it is necessary to mention the hydro- and vapor barrier characteristics. These properties make it possible to reduce the cost of insulation and speed up construction work.

There are several varieties material:

• penofol A: this material is used for insulating walls and various engineering systems;
• penofol B: a product with foil on both sides, intended for insulation interfloor ceilings, as well as various partitions;
• penofol C: this type has a layer of glue on one side and foil on the other, making penofol C optimal for installation in hard to reach places under unfavorable conditions.

It is worth mentioning the main specifications this insulation:

• thermal reflection 95–97%;
• thermal conductivity coefficient 0.37–0.51 depending on the type;
• water absorption 0.3–0.7% of the total volume;
• Possibility of use at temperatures from -60˚С to +100˚С.

Advantages and disadvantages

Many people prefer foil penofol, shown in the photo, because of its large list of advantages.

Naturally, foil penofol there are a number of disadvantages.

• The material does not have sufficient rigidity. For this reason, it cannot be finished with plaster or wallpaper.
• Some people use staples to fix the insulation, but in this case thermal insulation characteristics material may deteriorate. Accordingly, you should choose a special glue for fastening. As an option, you can purchase a roll of penofol, which has a self-adhesive backing.
• To really avoid heat loss, it is recommended to combine penofol with other insulation materials.

Application

Due to its versatility, the material is suitable for thermal insulation of apartments in multi-storey buildings, country cottages and small summer houses. It can also be office centers, industrial premises, hospitals, baths, warehouses and shopping kiosks. In addition, using penofol insulate the cars, shield heating radiators and wrap ventilation or water pipes.

The material is used separately or combined with other materials. Thanks to this insulation, it will be possible to insulate the walls, ceiling and floor. Many professionals use foil foam to process air ducts and hoods.

When using penofol, no special equipment is needed, which is important advantage. You can also perform work at any time of the year. In order for the insulation to hold well and not lose its characteristics, it is important follow simple recommendations.

Penofol recognized as excellent heat-insulating material . It can be safely combined with other insulation materials and installation can be carried out without the help of professionals. This type of finishing will help to preserve the optimal microclimate for a long time.

Today it is known a large number of insulating building materials. Every day, the market thermal insulation materials is expanding, and manufacturers are striving to improve their quality indicators.

Among various types insulation, it is worth highlighting reflective thermal insulation - foil penofol, produced in rolls. Let's find out what this material consists of and what characteristics it has.

Material structure

Foil penofol - refers to a type of reflective insulation. Such material has been created solely for the purpose of protecting various designs, from factors such as: draft, cold, wind, moisture and vapor. It went through several stages of improvement, as a result of which, combines such qualities as: sound, heat, steam and waterproofing.

Consists of several main layers:

1. The first layer is polyethylene , foamy consistency with closed pores. The pores are filled 90% with air, so the material prevents heat transfer. The first layer can vary in material thickness, density and structure.
2. Second layer - aluminium foil which reflects heat. Foil - penofol can be covered on one or both sides, which is reflected in the technical characteristics of the product, as well as its features. It is worth noting that the connection of foil with polyethylene is carried out by heat welding.

Available in thicknesses from 2 to 40 mm. The thickness of the foil varies: from 12 to 30 microns. The operating principle of foil penofol is based on the functioning of a thermos. Thanks to the air cushion, which is covered with a reflective element in the form of aluminum foil, it is possible to retain heat long time. The use of such thermal insulation material in the construction of a house makes it possible not only to significantly save on heating, but also to slow down the process of warming up the house in the summer.

Advantages and disadvantages

Penofol, like any other building material, has its advantages and disadvantages. Thanks to these important factors, manages to choose best option for insulating the house.

Benefits include:

Despite such a complex of advantages of penofol, has some disadvantages:

• The material is excessively soft, so it cannot be plastered like polystyrene foam;
• To secure it to the surface, you will need to use additional glue. Self-adhesive penofol is produced, which is free from such a drawback;
• Use penofol as an independent insulating layer for external walls buildings are not recommended. It can be used as an additional insulating layer.

Main technical characteristics

Having learned about the advantages and disadvantages, it is worth finding out what the main technical parameters This material has:

Kinds

Depending on the intended use of the material, manufacturers produce the following types:

• type A, covered with foil on one side only. It is also called one-sided;
• type B, presented in the form of a double-sided foil coating. Used for autonomous type of insulation;
• type C, self-adhesive penofol, which at its base consists of foil, polyethylene and a layer of moisture-resistant glue. This option is convenient for installation and does not require additional installation tools.

In addition to the three main types, manufacturers also produce the following options:

• type ALP, which is additionally covered with plastic film. This film is designed to protect the material from aggressive environments;
• type M and R, presented in the form of one-sided insulation with a relief base;
• type AIR, special materials, with the help of which air vents are arranged.

Application

As a heat insulator:

As additional element facilities:

Installation rules

Depending on the scope of penofol application, the methods of its installation differ. For installation work When laying material on the balcony, you should be guided by the following technology:

We insulate the walls of the house with penofol from the inside

To insulate walls from the inside, it is recommended to use penofol up to 5 mm thick. You should use a material with a one-sided foil element. If 5 mm of insulation is not enough, then it is better to additionally insulate the walls with polystyrene.

The installation principle consists of the following steps:

• First you need to measure required size insulation and cut it off;
• Using a stapler, you need to attach the material to the wall. For concrete wall you can use glue or staples;
• The material should cover the entire surface of the wall;
• The joints of the sheets should be taped with adhesive tape;
• A frame made of slats or plywood is installed on top of the foam foam;
• Then, plasterboard or chipboard is installed.

After the entire room has been covered with plasterboard, you can additionally insulate the house from the outside using polystyrene foam.

Using penofol, you can insulate the walls of the house from the outside, but after installation, you will need to protect it by covering the walls with plastic or corrugated sheeting.

Using this material as insulation for your home, you can significantly reduce your heating costs, since the material copes well with its main purpose - saving heat.

For a roll intended for insulation 25 sq. meters, 5 mm thick, total: 1200 rubles.

This video presents step-by-step insulation of a loggia using this material:

If you closely follow the market for building materials, in particular thermal insulation, read various reviews, we could not help but notice the appearance of a new thermal protection product with high technological qualities, penofol. This material can be classified as one of the types of reflective insulation; it consists of several layers - a base and a reflective foil.

The basis of penofol, which actually gave it its name, is polyethylene foam, which has different structures and density indicators. The foil is applied to the base by heat welding.

The penofol base has a thickness of 0.2 to 1 cm, the thickness of the foil is 20 microns, the reflection coefficient is 97%. For use in harsh climates, manufacturers produce a special type of penofol with a main field thickness of up to 40 mm.

If in the construction industry the material penofol appeared relatively recently, this does not mean that its high-tech qualities were not known. For interest, I can provide information that the first spacesuits for NASA astronauts were made using penofol.

What can the effect of this be compared to? With a vacuum cleaner! If you have used penofol to insulate a house or apartment, rest assured: you will always be warm in winter and cool in summer. The fact is that penofol does not retain the heat emanating from the room, but reflects it.

This modern technological material creates a barrier to direct heat transfer due to foamed polyethylene, which contains a large number of pores filled with air or carbon dioxide.

The use of penofol is possible both independently and also in combination with others. It is especially convenient when you, wanting to insulate some surface, do not want to lose the size of the usable area of ​​your room.

Foiled penofol: technical characteristics of the material

— heat transfer resistance for double-sided foam foam with a thickness of 4-5 mm is 1.2-1.23 m2xC/W
— vapor permeability is about 0.001 mh/mhch Pa

Foiled penofol It is used both as the main insulation and as a layer of a thermal insulation system.

The photo below shows an example of foil foam foam 10 mm thick.

Foiled penofol

Foiled penofol and its use

It can be used for:

- insulation of walls inside and outside the premises, attics and basements
— water and vapor barrier of saunas and baths
- roof insulation and
— insulation of water pipes
— heat reflection of heating batteries
- sound insulation and insulation of ventilation and sewer systems
— insulation and sound insulation of cars
— arrangement of residential and commercial trailers
— insulation of refrigeration chambers

Foiled foam foam has its advantages and disadvantages, which will have to be taken into account when choosing thermal insulation. I’ll immediately note that there are many more advantages from using penofol and I’ll start with a fairly moderate price, in comparison with other materials.

What other benefits does the consumer receive:

- high environmental friendliness
- the material is very thin compared to others
- low vapor permeability
— good sound insulation
- ease of installation
— high fire safety
- ease of transportation
— the material is difficult to reach for rodents

To the main disadvantages I'll take:

- high flexibility at the slightest pressure due to the softness of the material

— some inconveniences during strengthening: special glue compositions are needed, etc.

- if you need to insulate the walls outside your home, foil penofol is only suitable as an additional layer of thermal insulation to reflect thermal energy and protect against moisture.

We test penofol for strength - watch the video:

So, we decided that we need exactly this type of thermal insulation.

What types of penofol are presented on the market and features of their use

1. Type A— in this type of penofol, the aluminum layer is applied only on the outside.
It is used more often with polystyrene foam and styrodur.

2. Type B- coating on both sides.
Suitable for independent use.

3. Type C— self-adhesive penofol.
Him outer side covered with a layer of aluminum foil, and on the inside - polyethylene foam with contact adhesive.

4. Type ALP.
Glued on top of the aluminum layer polyethylene film. This type of penofol is called laminated. Effectively used for the needs of rural areas.

5. Type R and M— one-sided foil embossed penofol.

6. Super NET, which means "network".
Used to isolate networks.

7. Penofol AIR for air ducts.

If you see penofol brand on the store counter Penofol-2000, know that this insulation is the most inexpensive view penofol, i.e. worse in all technical characteristics and, above all, in strength.

Basic methods of installing foil foam foam

— the reflective layer of material is always laid towards the source of heat transfer
- it is necessary to leave an air space of 10-20 mm on both sides of the insulation
— for 100% waterproofing and tightness, all joints are taped with foil tape
- the most important thing: remember that foil is a very good conductor of electric current, carefully check the insulation of the electrical wiring

As mentioned above, one of the remarkable qualities of penofol is its ease of installation. Therefore, even without any special knowledge, you can use it yourself when insulating your house with your own hands.

Insulation of walls with penofol from the inside

For fastening you will need a stapler or self-tapping screws. Indoors, as a rule, penofol with a thickness of 4-5 mm is used. If you have ordinary apartment or home, take one-sided material. If the walls get very cold, you will have to additionally insulate them with cotton wool or.

Insulation of walls with penofol from the inside

Procedure:

- roll out the foam foam roll and cut a strip from it, the length of which will be equal to the length of the wall

- using a stapler, nail it to the wall, starting from the ceiling

- if the wall is wooden, take a screwdriver; if it is concrete, put it on glue or nail it with staples

- cover the entire wall with penofol so that there are no overlaps

- cover the board with aluminum adhesive tape

- nail a frame made of river or a layer of plywood 2 cm thick onto the penofol

- place plasterboard or chipboard on top of the sheathing

In order to insulate the ceiling using penofol, cut it and attach it along the wall, starting from the middle. When you reach one corner, nail the side that is closest to the wall. Next, move from the middle in the opposite direction and attach the strip further.

Then move perpendicular to the material sheet towards the corners, all the while smoothing the penofol across the ceiling.

I would like to remind you that penofol is a very unpretentious material to use. When installing it, you don’t have to treat the surface with anything or even pre-prepare it for work.

It should be taken into account that steam entering building structures can lead to the appearance of mold and mildew. But when using penofol indoors, your walls will not accumulate moisture.

Choose penofol types A, B, C for installation inside the house.

Now let's try them insulate the walls of the room from the outside.

By the way, many professionals claim that this insulation method is much more effective than internal insulation, especially if you have a wooden house.

For insulation work on the outside of the house, use perforated penofol; it will protect the walls from precipitation and wind, and will also preserve the integrity of the area of ​​your home without reducing it.

Insulation of external walls with penofol

The insulation is installed between the wall and the cladding of the house. Better work to insulate the walls from the outside in the summer, because there are no sharp temperature fluctuations and the walls are already sufficiently dry.

Procedure for insulating a house with penofol from the outside

- remove all coverings from the walls and carry out antiseptic treatment, be especially careful and meticulous when processing corners and the bottom of the walls, because... it is these areas that are prone to freezing and putrefactive processes

- build a frame from bars and attach it with self-tapping screws

- lay penofol, not forgetting to leave a gap for air

- seal all joints with foil tape

- mount the outer frame and begin cladding the room

So, today we have studied in some detail the properties of penofol, one of the most popular modern thermal insulators. If you want to protect your home not only from cold and moisture, but also from noise, if you are interested in maintaining maximum usable area premises and still be in financial gain, give your preference to this magnificent material.

The name Penofol has become so popular that this foamed polyethylene with foil is sometimes used where it is not needed, to the detriment of the result with monetary losses. The frenzied popularity is facilitated by sellers who, for the sake of sales, attribute foamed polyethylene miraculous properties. Let's look at how Penofol is used correctly and why owners sometimes experience losses with this material...

What is Penofol?

Foamed polyethylene with foil is a soft and elastic rolled material, usually from 3.5 to 10 mm thick, for use as a substrate, vapor barrier, wind barrier, insulation layer.

According to the manufacturer, the thermal conductivity coefficient of uncompressed material is in the range of 0.037 - 0.05 W/m °C. For comparison, foam has 0.035 - 0.04 W/m °C - the material is a little warmer...

The glued layer of aluminum foil reflects infrared radiation, preventing it from escaping from a heated house to a cold street. And also impermeable to water vapor.

Available in thicknesses of 3 - 10 mm, most often in rolls up to 36 meters long, with a width of 1200 mm.

The material is very light and easy to process, cut with scissors, attached with glue, or pressed with screws or lathing. Convenience and ease of use, as well as low price, contribute to popularity and... misuse.

Types of Penofol

There are:

Thermal insulation qualities of Penofol

It should be noted that when compressed to 2–3 times the original thickness, air is partially displaced from the material, and the thermal conductivity coefficient increases significantly. At the same time, reducing the thickness of the layer leads to a proportional decrease in heat transfer resistance. This means, at least, that Penofol, as insulation, should not be used in a compressed state.

On the manufacturer's website you can find the following values:

• heat transfer resistance R of PENOFOL® insulation in a structure with a closed air gap is 1.175 – 1.362 m2C/W.

Apparently so high value for a thin layer of insulation we obtained by adding up the heat transfer resistance of directly foamed polyethylene with a thickness of 5 - 10 mm - only 0.15 - 0.3 m2C/W, and also by adding here the heat saving from foil (a barrier for radiant heat), which completely depends on the radiation power from the inside, the temperature in the room, the presence of heating sources, the degree of absorption of radiation by structures, and also, apparently, also adding resistance to the “closed circuit” air gap» design, which can actually reach 1.0 m2C/W, for example, in a double-glazed window.

However, the obvious fact is that Penofol really does insulate, all that remains is to apply it correctly.

Basic rules for using Penofol

Where and how is Penofol mainly used in practice?

Experts warn. Large-scale use of shielding with conductive foil can disrupt the natural magnetic background, increase (decrease) electromagnetic intensity, disrupt the operation of transmitting and receiving devices, which cannot be called useful and correct...

Examples of incorrect and dangerous use of Penofol

• Laying Penfol under a cement (reinforced concrete) screed. The foil is destroyed by the alkaline aggression of concrete, the insulation layer is compressed excessively. There is no warming effect.
• The use of Penofol as the main insulation layer in structures that must be insulated in accordance with standards - in floors, in roofs, in walls. At the same time, users are usually guided by sellers’ assurances that the material replaces “5 centimeters of polystyrene foam” or “6 centimeters mineral wool" As a result, without a main insulating layer (in most cases, it is economically optimal from 10 cm effective insulation...), the structures remain cold.
• Application from the living space directly onto Penofol, without leaving an air gap, finishing panels, wood finishing, structures made of wood, which entails dampening of the finish, the development of mold, and rotting of the wood due to condensation accumulated on the vapor barrier insulation. After a year of such use, according to the owners, Penofol is “black with mold.”
• Laying inside panel structures along the foil side of the electrical wiring.
• Joining Penofol sheets leaving gaps, which, in addition to a general reduction in insulation, in some structures leaves greater air permeability (drafts), which completely eliminates the presence of an insulating layer.

The construction of any facility is impossible without the use of thermal insulation materials. With their help, resource costs for heating are reduced. One of the popular solutions is foil penofol. It is chosen for its excellent characteristics. The installation procedure for the material does not contain any difficult aspects. Even a beginner can easily handle this work. Compared to other solutions, it costs significantly less. As a result, quality and inexpensive insulation premises.

Penofol is one of the most popular and widespread types of insulation.

Features of the structure

Penofol is usually classified as a reflective insulation product. It was developed specifically for protection various surfaces from negative factors such as cold, moisture and steam. Over the years of its production, the product has been improved. As a result, he acquired not only wonderful thermal insulation properties, but also protection from water and sound. Its structure contains several layers:

This material belongs to the heat-reflecting category thanks to the foil, which is attached to the polyethylene “foam”

1. The first one is polyethylene foam. It has many pores closed type. They are 90% filled with air. This is what prevents heat transfer.
2. Aluminum foil is the second layer. It provides effective heat reflection. Penofol can be covered with foil on one or both sides. This point influences its main technical characteristics and also determines the application features. To reliably connect the base with the metallized layer, the heat welding method is used.

If you have not yet decided on the choice of foil insulation for your home, be sure to watch this video:

For polyethylene, the thickness varies from 2 to 40 mm, and for foil this parameter ranges from 12 to 30 microns. The presence of an air cushion, which is covered with a reflective element, ensures heat retention for a long time. The use of penofol during the construction of a house makes it possible to save on heating the home. In summer, the heating of the object slows down noticeably.

Specifications

Penofol differs from most other materials in that moisture does not have any effect on its characteristics.

When studying foil penofol, consumers study the characteristics first of all. They are one of its advantages. Such an important parameter as thermal conductivity of this solution is quite comparable with the indicators present in mineral insulators. Its use for attic insulation reduces heat loss in winter time. Thanks to the metallized layer, the material is able to reflect up to 97% infrared radiation. As a result, its use is an opportunity to create comprehensive thermal insulation of a room.

The insulator absorbs moisture well, and its vapor permeability tends to zero. It differs from most other materials in that moisture does not have any effect on its characteristics. Change temperature regime also does not change them. When penofol is used for thermal insulation work, there is no need to create steam protection. The insulation acts as a good barrier to its penetration.

To solve problems of effective sound insulation, foil penofol is mounted directly on top building structures. At the same time, in terms of environmental friendliness, it is one of the most best solutions. The durability of the insulator is also at a high level. Its use allows not only to insulate the room, but also to prevent the penetration of electromagnetic radiation inside.

The main application of this insulation is the roof, walls, bathhouse, loggia, where there is a layer for reflection

Advantages and disadvantages

Like any solution in the field of thermal insulation, penofol has certain advantages. They are the first thing consumers consider when looking for an effective insulator. Positive characteristics:

1. The versatility of the material. It is actively used for work during the construction of facilities and during repairs. It is often used as the main insulation to improve the performance of balconies.
2. Minimum thickness. Low values ​​of this parameter do not affect the insulating properties in any way. For example, penofol with a double-sided foil coating 4 mm thick is an excellent replacement for an 8.5 cm mineral wool layer.
3. Easy installation procedure. The absence of difficult moments during installation allows you to refuse to purchase special tools. To cut the fabric, you can use a regular knife. For secure fastening, a regular one is suitable. furniture stapler, tape or nails small size.

   The ease of installation of penofol allows even non-professionals to work with penofol independently

4. Penofol is an environmentally friendly material. The components that are used to create it are often used for storage food products. Some companies producing this solution claim that it is able to provide protection against radiation.
5. High fire safety. This insulation will never cause a fire, since it is classified as a low-combustible material.
6. Rodents are indifferent to this heat insulator.
7. Ease of transportation. Penofol is produced in the form of rolls. They are easy to place even in the luggage compartment of a car.

Although penofol has many advantages, it is still not without its disadvantages. One of them is excessive softness. This feature imposes certain restrictions on use: the material cannot be used for thermal insulation of walls under plaster or wallpaper; in some cases, special fixing is required adhesive composition(this minus is absent if the consumer has chosen self-adhesive insulation for the work).

Although the foil insulator has good characteristics in terms of thermal insulation, it should not be used as the main solution to improve the performance of external walls. It is ideal as an additional layer of insulation to improve the protection of the structure from moisture and enhance the reflection of thermal energy.

Scope of application

Speaking about foil penofol, the use of this insulator can be varied. In this regard, he is universal material. It can be used to insulate surfaces in apartments and country houses. Due to its characteristics, it is often chosen for thermal insulation of the foundation, as well as when performing repair work in the house. This solution is most effective for thermal insulation:

1. Residential buildings.
2. Baths and saunas.
3. Administrative and industrial facilities.

It can also be used to improve the structural performance of public buildings. For example, in hospitals and kindergartens. It is excellent for insulating heated and cold hangars, as well as warehouse buildings.

Surfaces insulated with this insulation do not release heat to the outside in the winter. In the summer months, penofol provides comfortable conditions for accommodation. To keep the house from getting hot, it is enough to simply arrange a layer of this material in the under-roof space of the structure.

Installation nuances


This soft material, therefore it cannot be laid under plaster; another finishing coating will be required, for example, plasterboard or Wall panels

The procedure for laying a heat insulator has certain features. Taking into account the nuances can be provided high quality works and exclude extra costs for heating:

1. When laying penofol with a one-sided metallized layer, it should face towards the heat source.
2. During installation, it is necessary to arrange air gap. His optimal size- 2 cm. It is necessary for effective ventilation.
3. When fixing the insulation, any joints that arise between the sheets must be eliminated using foil tape.
4. The butt-to-end connection method ensures uniform thermal reflection from the insulator. However, when work is carried out on a loggia, joining the material with an overlap of up to 10 cm is quite acceptable.
5. When carrying out the procedure, you need to remember that one of the layers of this solution - aluminum foil - conducts well electricity. Therefore, if the insulation is located close to the electrical wiring, then you need to think about high-quality insulation wires

When thermally insulating roofs or inclined walls of attics, installation of penofol is carried out by attaching to the lower planes of rafter boards

When choosing penofol, the technical characteristics should be found out first. This will allow you to choose the best option to solve the problem at hand. Foil insulator is good decision when it is necessary to perform high-quality thermal insulation object. Its advantage is its small thickness and ease of installation. Even a beginner can handle the installation work. You just need to know the basic nuances when carrying them out.

Many consumers who have chosen penofol are also interested in the flammability of the insulation. There is no need to worry about this - it is classified as low-flammable. When installing it, it is worth using the overlap method. It is best to use aluminum tape to seal joints.

At making the right choice Insulation can be omitted from installing a waterproofing layer. The result is good savings for the owner of the facility and a serious improvement in the thermal insulation characteristics of the room.
