How to fix penofol to the ceiling

What is "Penofol" and its analogues

Thin polymer insulation is made from the following materials:

The main insulating layer is 3 ... 10 mm thick foamed polyethylene with closed air pores. The thermal conductivity coefficient λ of this interlayer lies within the range of 0.037—0.051 W / (m • ° С), depending on the operating conditions.
The outer reflective layer is 14 micron thick aluminum foil, securely glued to the polymer base.
The third layer on the back of the polyethylene can be glue for ease of installation, or the same aluminum.

Reference. All specifications are taken from the manufacturer's official website. Thermal insulation performance of other brands may vary. For example, the thickness of a similar material reaches 150 mm.

The peculiarity of the material is impermeability to moisture, the declared indicator is simply scanty - 0.001 mg / m • h • Pa. The insulation is quite light - the density is in the range of 16 ... 35 kg / m³, it is sold in rolls. Due to these parameters, the material serves well as an internal vapor barrier.

Penofol is available in 3 versions:

two-layer type A;
three-layer - the base is covered with aluminum on both sides (type B);
the same, with an adhesive layer - Type C.

The foil side acts as a reflector of the radiant (infrared) component, the polyethylene foam resists direct heat transfer. For wall cladding outside, the perforated version of "Penofol" is offered, shown in the photo. Many small holes are intended for the escape of water vapor from the thickness of building structures.

The outer wall cladding is made with a special perforated insulation

How to insulate walls, ceiling and floor with penofol ...

It is quite simple to insulate various designs with penofol, primarily because this material is very light and malleable, it is cut, takes shape ... But is it necessary to insulate with penofol? What is the effect of this compared to the cost of materials and labor? After all, insulation should be economically viable and create additional comfort.

Many sellers of penofol deceive buyers, ascribing qualities that are physically unattainable to the material. For example, it is stated that 5 mm of foam foam is equivalent to 45 mm of foam in terms of thermal insulation qualities. Let's figure out where this fiction comes from.

Penofol for insulation - foamed polyethylene foam

Penofol - foamed polyethylene, - has a thermal conductivity coefficient of the order of 0.04 - 0.05 W / (m • ° C), depending on the production. But when its layer is compressed, the coefficient increases sharply, therefore, penofol compressed by 2 - 3 times no longer has significant resistance to heat transfer.

For example, foam plastic has a thermal conductivity coefficient of 0.037 W / (m • ° C) on average, which is comparable to previous values. Consequently, penofol with a thickness of 5 mm will be approximately equivalent in resistance to heat transfer of 5 mm of foam or 5 mm of mineral wool, which also refers to effective insulation.

But penofol is more often sold, and then installed as a sheet of foamed polyethylene covered with foil. What is the role of foil and does it have "miraculous" qualities?

Foil - infrared reflector

Foil on expanded polyethylene acts as a reflector of infrared waves. Installing foil in structures is one of the energy saving methods. True, it did not receive wide distribution.

Partly due to the fact that very little infrared heat escapes through dense heavy structures that are insulated from the outside, since it heats up the structures, i.e. stays indoors. Most of the radiant energy escapes from the building through the windows. But nobody hangs foil on them, and glass with metallized spraying is used ...

Secondly, wrapping the house with foil distorts the electromagnetic background in it, which is not useful at all. The operation of radio devices may also be affected.

The foil will work well as a reflector of thermal energy coming from the room if in front of it, from the side of the warm space, there is an air gap (a gap with loose material), into which the actual electromagnetic wave of the infrared range will be reflected.

Can penofol replace foam 10 times thicker ...

In laboratory conditions, if an infrared heat emitter is directed at the foam foil insulation, then almost all the radiation heat reflected from the foil can be caught. In this case, the effect of energy saving will turn out as if foam was used 10 times thicker.

But it should be noted that with the same success you can use any other foil insulation - foam with foil, or mineral wool. Or just foil without insulation.

Such far-fetched experiments have almost no practical meaning, since they run counter to the classical methods of insulating buildings from the outside, foil is almost never used in typical structures of residential buildings. And where is it needed, where is penofol suitable in the best way?

Penofol insulation of the balcony

Balcony fencing can only be provided with a lattice or plastic sheathing. There is nothing to get stuck in the infrared wave here, therefore the leakage will be the same as through the window opening. Foil insulation will help out. If there is no foil-clad foam, then you can use the usual one - plates 10 cm thick and, plus, sheathe them with foil-clad foam.

The thickness of the foamed polyethylene itself 5 or 7 mm does not play a practical role. Against the background of the thickness of the more heat-saving foam 50 - 100 mm, these figures are not indicative. Therefore, you can use the thinnest and cheapest, but foil-clad penofol.

The balcony is insulated from the inside. It is better to insulate its ceiling, floors, sides made of reinforced concrete slabs from the inside with extruded polystyrene foam, which does not accumulate moisture. At the same time foil - why?

If they were insulated outside according to the classical technology, then the plates would be heated and there is no point in installing reflective foil in front of them. But in the case of a balcony, which is insulated from the inside, the slabs will remain behind the insulation in the cold zone, cold, and here the infrared heat will already warm the street, so it is more expedient to reflect it back into the room with the foil installed inside.

Where you do not need to use penofol

The strangest solution is to put penofol under the screed. There it turns into a thin film that negligibly affects heat transfer, and the foil under the concrete does not help in any way. In addition, aluminum foil is not friendly with cement products; in contact with them, it quickly collapses, unless it is separated by another layer of film or lamination. Therefore, rolling penofol into concrete is a strange way to throw money down the drain.

Also, the insulation of concrete walls, structures outside with penofol does not at all represent expediency.

Laying a layer of foamed polyethylene foam between the rafters of the roof or attic floor can serve as a good cause of reflecting infrared heat back into the room, if not for the harmfulness of creating a metallized tent.

But laying penofol between the logs of a wooden floor looks more purposeful.

The use of foamed polyethylene with a layer of 5 - 8 mm, as thermal insulation, plays in most cases a very small role in comparison with the norms of conventional insulation - from 50 mm of effective insulation. Therefore, it can be significant only where it is necessary to fight with air permeability at the same time, laying such a layer of insulation instead of a plastic film, closing the joints in something and at the same time slightly warming, for example, when building a doghouse.

Penofol properties and characteristics

Penofol is a rolled multilayer insulating material consisting of expanded polyethylene with a closed cell structure and a layer of aluminum foil. It has the property of reducing heat loss in a convective and radiative way. In terms of efficiency, the material surpasses other insulating materials due to its high moisture resistance, minimal weight and several times smaller thickness.

The efficiency of reflection of heat waves due to the use of a polished foil layer is more than 97%. Its thickness is only 12-30 microns.

Due to the cellular structure filled with air, the thermal conductivity is significantly reduced, which is 0.037-0.052 W / m · K, with a thickness of the polyethylene layer up to 10 mm. The level of water absorption is also minimal and does not exceed 0.7% of the total volume.

It is important to note that the vapor permeability of the insulation is not violated, the value of which is from 0.001 mg / m ∙ h ∙ Pa. This allows it to contact without problems with wood and other natural materials without the appearance of condensation, mold and mildew.

Penofol close-up

Insulating a house from the inside with penofol is also beneficial due to its following characteristics:

operating temperature range from -600C to + 1000C;
resistance to compressive stresses up to 0.035 MPa;
sound insulation level up to 32 dB;
the material belongs to the class of hardly flammable;
standard roll sizes: width from 58 to 120 cm, insulation area 18-36 m2;
specific gravity 44-74 kg / m3;
specific heat capacity 1.95 J / kg · K.

What is better foil foam or basalt insulation

The building materials market is full of types of insulation. They have their own characteristics, positive, negative sides.
General parameters of thermal insulation:

The weight. The insulation should not weigh much, because when mounting it on the structure there should be no weighting.
Thickness. The thinner the material, the more space is left in the room.
Low thermal conductivity.
Moisture permeability. The material should absorb moisture as little as possible.
Noise isolation. Does not pass sounds from the street.
Environmentally friendly material. Should not emit harmful substances.
Easy to install.

Comparing basalt insulation and foil foam, you need to compare their characteristics.

Basalt wool

Produced from rocks of volcanic origin. It does not burn, has good sound insulation performance, and does not lose its qualities over time. It is completely safe for health.

Penofol - application

Produced from polyethylene foam with a porous structure. A layer of foil is glued on top as a heat reflector. This heat-insulating material is several times thinner than basalt wool. In addition, it reflects heat and practically does not absorb it.
Which insulation to choose depends on the budget for the insulation, as well as personal preferences.

Scope of application

Due to its high technical characteristics and versatility, penofol is widely used as a heater, both in the industrial sector and in the arrangement of residential buildings, household agricultural buildings.

In the construction of buildings, foil-clad material is used for thermal insulation:

ceilings;
floors;
external and internal walls;
windows and doors;
roofs and attic spaces;
basements.

Penofol is used for thermal insulation of various types of pipelines, ventilation, heating and water supply systems, as well as railway cars, trucks and cars.

Pros and cons of wall insulation with Penofol from the inside

The material has more than enough advantages - it is not for nothing that it has become so widespread. Let's name the following positive qualities:

Saving usable floor space
... This became possible due to the small thickness of Penofol in comparison with other heaters. At the same time, it can replace heat insulators with a thickness ten times greater.
Good thermal insulation
... Provided by the reflective ability of the material.
High degree of environmental friendliness
... The insulator is practically non-toxic, because it is made on the basis of aluminum foil and polyethylene, which have long been used in the food industry.
Fire safety
... This quality is due to the fact that Penofol is classified as a non-flammable material.
Low vapor permeability
... In this case, it does not matter what the weather is outside the window, since moisture is not absorbed by the insulation.
Sanitary safety
... Penofol is considered a material that is difficult to reach for rodents.
Convenient to transport
... This is due to the fact that the heat insulator is rolled up and easily transported.
Excellent sound insulation
... If this material is mounted on the main structure, then it will help protect against acoustic noise.
Ease of installation
... Penofol can be easily cut with any knife, and it can be fixed not only with small nails, but even with tape. But at the same time, it is difficult to break or crumble.

However, as is the case with other heat-insulating materials, Penofol has certain disadvantages. They are as follows:

The need for an additional layer that will help in reflecting heat energy and protecting against moisture ingress.
The lack of sufficient rigidity does not allow using it under plaster or wallpapering. The material can be pressed through with light pressure.
The need to use special adhesive mixtures, since the insulator is not recommended to be nailed to the wall - from this it loses some of its thermal insulation qualities.

Views

There are 3 main types of penofol, depending on the production technology, dimensions and technical characteristics:

Type A

Polymeric insulation material of various thicknesses, foil is applied only on one side of the building material. This type of heater is popular in the complex insulation of building structures; it can also be combined with some heaters: glass wool, mineral wool.

Type B

Insulation covered with foil on both sides. Thanks to this design, the material has the maximum insulation effect.

This type of insulation is used for thermal insulation of load-bearing structures of the attic, waterproofing of basements, floors and walls. The foil material laid under the roof prevents heat from entering the room.

Type C

Self-adhesive penofol, which is covered with foil on one side, and on the other, a thin layer of adhesive is applied to it, covered with a film. Depending on the size of the product, it is used on almost any surface, which saves time. Before starting work, this building material must be cut into strips of a certain size.

Regular penofol (types: A, B, C) has a white base, while penofol 2000 has a blue base.

There are several more types of penofol that are not in great demand among consumers.

R type

One-sided insulation, which has a relief pattern on the foil side of the insulation. It is similar to type A penofol, but it is mainly used as a special decoration element for interior decoration.

What is Penofol

The material belongs to a new generation of ultra-thin polymer insulation made using foaming technology. In this case, we are dealing with expanded polyethylene welded to a layer of reflective aluminum foil.

Thanks to the manufacturing technology, small pores inside the foam foam have a closed structure, which makes the insulation practically impervious to water vapor. According to the manufacturers' assurances, the foil layer is designed to reflect infrared heat streams coming from inside the premises. There are 3 main types of penofol:

with one layer of heat-reflecting foil (type A);
the foil is welded to the insulation on both sides (type B);
on one side of the material there is foil, on the other - an adhesive layer (type C).

Note. One of the latest innovations is one-sided (type A) perforated penofol. Many tiny holes are made in the insulation to make it vapor-permeable.

The scope of application of penofol is thermal insulation from the inside of houses and apartments, including balconies and loggias, as well as any industrial premises. Insulation is offered in thicknesses of 3, 4, 5, 8 and 10 mm. In order to finally understand all the properties of the material, we suggest that you familiarize yourself with its technical characteristics presented in the table:

Dimensions (edit)

Penofol is produced in rolls of various lengths, the maximum size of which is 30 m. The width of the web varies from 0.6 to 1.2 meters. The thickness of the material depends on the type of foam foam. Standardized material thickness: 2,3,4,5,8,10 mm. In rare cases, 40 mm thick materials are produced.

The foil material, which is 1 cm thick, has a high level of noise protection and retains heat much better. Insulation with a thickness of 5 mm, which has high technical characteristics, is very popular.

Penofol is available in rolls. The standard length of the rolled sheet depends on the thickness of the building material and is 5, 10, 15, 30, 50 m.

Features of thermal insulation with foam foam ceiling

Penofol is a multilayer synthetic material, the basis of which is a canvas made of foamed polyethylene foam. It is considered not quite an ordinary insulator due to its specific principle of operation. Outside, the sheet is covered with aluminum foil up to 10 microns thick to reflect heat in the direction where it is needed. The presence of a mirror surface retains 97% of the heat.

There are several modifications of the product, which differ in the placement of the metallized shell on one or two sides and the presence of an adhesive layer.

The insulation has unique properties that prevent heat leakage through convection, conduction and infrared radiation. Other modifications do not have such a wide range of protection. It is able to replace several different insulators or one, but thick. For reference, the standard material thickness is 2-10 mm. There are more massive samples, but they are inconvenient to work with.

Penofol is used in household and industrial premises as the main and additional insulation. In addition to the main function, it solves the issue of vapor barrier. It is often used in baths, saunas, steam rooms.

The material cannot be fastened with nails or self-tapping screws due to a significant loss of reflectivity when the foil is damaged. Therefore, manufacturers recommend fixing it with an adhesive solution. The result is improved if there is a gap of 15-20 mm between the ceiling and the panel. Usually, after installation, a decorative ceiling is made under the panel, but in basements, garages and industrial buildings it is left "naked".

Often used with other insulators such as foam. In such structures, the foam is first attached, then insulation is glued to it, and the whole "pie" is covered with sheets of drywall.The room will perfectly keep the temperature: cold does not penetrate from the inside, and heat does not come out.

The nuances of installation technology with penofol

Foil penofol is one of the best materials for home insulation. With its help, it is possible to provide high-quality thermal insulation of both the inner and outer parts of the building. At the same time, the entire installation process is not particularly difficult, and you can do the insulation yourself.

Tools and materials

To insulate a residential building, it is enough to use penofol brands "A", "B" and "C". To install it, you need to select the following tools:

chancellor's knife;
construction stapler;
a hammer;
screwdriver;
roulette.

The following materials will be used during the installation process:

penofol in rolls;
wooden slats with a thickness of 1.5 to 2 centimeters;
staples;
adhesive composition;
self-adhesive aluminum tape.

Fixing the insulation can be best done by means of staples, but self-tapping screws are also well suited for these purposes.

Insulation of the walls of the house from the inside

Internal thermal insulation of walls with penofol will allow not only to keep warmth in the house, but also to protect against the formation of moisture. The installation of the material is carried out in the following sequence:

Fasten the slats vertically to the wall surface. It is recommended to keep the distance between the wooden elements 60 centimeters, since the width of the insulating material is 1 meter 20 centimeters. Such parameters provide a convenient use of foil-clad canvas.
Lay penofol on the wall between the wooden frame. Thermal insulation sheets should be placed with the reflective side inside the room. Laying is done so that the edges of the material are in the middle of the installed strip. Each next canvas is mounted end-to-end to the previous one. The material is fixed to the staples.
Ensure sealing of the seams. All joints should be glued with a special self-adhesive tape.

Penofol insulation of the walls of the house from the inside
A frame made of wooden slats is stuffed onto the insulated surface of the wall. Its design depends on the type of future finish.

Ceiling and roof cladding

Preliminary insulation of the slopes of the attic roof is proposed to be done according to the following scheme (shown above in the drawing):

On top of the rafters, waterproofing is laid horizontally - a diffusion membrane, the minimum overlap is 100 mm. The order of attaching the canvases is from bottom to top.
The membrane is pressed against the beams by counter-lathing bars, the horizontal boards of the main lathing are nailed to them. A roof covering is mounted on top - metal tiles, slate, profiled sheet and so on.
From the inside, horizontal beams 50-60 mm thick are attached to the rafters, the installation pitch is 60 cm.
A three-layer "Penofol" type B with two foil surfaces is targeted at the bars. Note that thin insulation bypasses the rafters so that there is a gap on both sides.
Internal cladding is screwed vertically to the ends of the bars - lining, moisture-resistant gypsum board, chipboard panels or other finishing materials.

Attention! A roll of "Penofol" is rolled vertically on the surface, adjacent canvases are stacked end-to-end, not overlapping. Carefully glue the seams with aluminum tape.

For gluing the joints, an assembly tape with a width of at least 50 mm is used

In this case, the insulation reflects heat flows from both sides, which is very useful in the summer, when the metal roof gets very hot. The inner layer remains unventilated, moisture from the outer air is removed through the membrane. Since "Penofol" serves as a barrier to steam, in the attic it is necessary to organize a natural exhaust through a separate ventilation duct.

Please note that an inaccuracy was made in the drawing above - there is no external counter grill, which creates a ventilation duct above the superdiffusion membrane.In the next version of the diagram, which shows the insulating "pie" of the attic roof, the frame of the lathing is clearly visible. What is the difference between this sheathing method:

Between the rafters there is a thick layer of the main insulation - 120-200 mm of mineral wool.
The bottom of the mineral wool is hemmed with a two-layer "Penofol" type A right along the ends of the beams. The aluminum faces into the attic room, the canvases are turned horizontally.
Between the polyethylene and mineral wool insulation, a gap of 2-3 cm is left, from the side of the foil - about 4 cm.
Bars for interior decoration are nailed to the ends of the beams directly through the polyethylene layer.

The foil surface faces the inside of the room, a gap is provided between it and the cladding
The section clearly shows that "Penofol" plays the role of an additional insulator and vapor barrier - the traditional film from the inside is not used. The moisture formed in the mineral wool is removed through the upper air and the waterproofing membrane. Vapors from human activity are removed by supply and exhaust ventilation.

Advice. When working with Penofol, it is important to understand the essence: we always leave a layer in front of the foil, we lay the polyethylene base close to the building structures. We connect the canvases only end-to-end.

Ceilings are insulated according to a similar principle:

If from the side of the attic the wooden floor is covered with expanded clay, sawdust or reeds, it is enough to lay 1 layer of "Penofol" type B, making gaps with the help of the crate.
Type C material can be glued directly to the concrete ceiling, foil downwards. Next, mount the frame for attaching the gypsum board or other finish.
When capital insulation of the ceiling is required, use the attic scheme, only without the membrane and outer sheathing. Install a frame made of beams or galvanized profiles, insert the main insulation between them, then hem the bottom with type A polyethylene foam.

If "Penofol" is the only heat flow insulator (which is not always correct), choose the maximum material thickness - 8 ... 10 mm. In tandem with other heaters, a sheet with a thickness of 3-4 mm works well. For more details about the device of the attic roof, see the video:

Floors and ceilings

We want to warn you right away: when insulating an existing wooden floor, it will not do without opening. You need to remove the topcoat and get to the log in order to properly lay the reflective thermal insulation. The overlap can be insulated according to a simplified scheme, repeating the insulation of the roof:

A roll "Penofol" type B with a thickness of 8-10 mm is rolled across the log. The material is aimed at the beams in such a way that 2 layers are formed at the top and bottom.
The second canvas is laid end-to-end with the first, fixed with a stapler, and then glued with metallized tape.
A rough floor and a topcoat are laid on top of the log.

An important nuance. In theory, the roll can be rolled directly underneath laminate or linoleum. But the whole point of reflective insulation will be lost - the aluminum coating will not work.

The second option provides for laying one-sided "Penofol" type A under the rough floors with a foil layer downward. Note: a large cavity remains under the thin insulator, equal to the width of the log. If the room is located above a cold basement or an unheated room, be sure to lay 10-15 cm thick mineral wool between the beams. Do not forget to provide a layer of 20-30 mm between the polyethylene foam and the mineral wool.

Penofol is a new generation thermal insulation material. Among the alternative options for insulation, it is distinguished primarily by the presence of a foil layer, because of which it has certain advantages.We will consider the features of the installation of penofol and its application further.

Characteristics and properties of foamed foam

Penofol is called foamed polyethylene foam, covered on one or both sides with the thinnest layer of foil, with heat loss, heat is transferred in two ways:

convection;
through heat radiation.

But, most heaters are designed to prevent heat transfer in one of the above ways. Penofol is able to prevent both convection and heat transfer of heat. Therefore, its thermal insulation performance is significantly higher than that of alternative types of insulation.

Namely, because of this structure, penofol is an excellent heat reflector, and does not allow air convection. With an insulation thickness of 10 cm, it is able to retain heat several times higher than a wall made of brick 50 cm thick.

In addition, this type of insulation is characterized by ease of installation, vapor tightness and good protection against various kinds of radiation. Due to the presence of good technical characteristics, the material is used both for insulation of residential and public premises, and for thermal insulation of baths, warehouses and pipeline systems.

Foil-type penofol is classified as reflective insulation. Since it is distinguished by the presence of closed pores and polished foil, which allow it to retain heat at a very high level.

In the process of installing foil-clad foam, there is no need to install waterproofing and vapor barrier materials, and, as a result, the costs of carrying out this type of work are reduced.

The most common are three types of foil-clad penofol:

1. Class A materials - differ in the presence of foil on only one side of the insulation. It is used in the process of insulating the roofing sections of the building and utilities.

2. Class B insulation features a double-sided foil coating. It is used in the process of warming interfloor ceilings and various kinds of internal partitions.

3. Penofol C class is characterized by the presence of a foil coating on one side and an adhesive layer on the other. It is used when carrying out installation work in inconvenient areas of insulation.

In addition, there are penofol options with a mesh layer and foil, with a foil coating and a laminated polyethylene film, with a relief polyethylene foam structure, etc.

The material is most often produced in roll form, it varies in thickness from 3 to 10 mm.

Penofol foil application and advantages

Since the foam cover is made of aluminum foil, it is capable of reflecting about 98% of thermal energy. Thanks to this, a comfortable temperature is maintained in the room: it is cool in summer and warm in winter. Due to its strength and flexibility, penofol fits perfectly on any surface, in addition, it has significant steam, heat and sound insulation characteristics that remain throughout the entire period of its use.

The scope of use of penofol extends not only to residential buildings, but also to industrial and civil construction. It is used for the purpose of performing thermal insulation on ceilings and attic floors, when arranging floors, installing wall panels, to improve the thermal insulation of basements, attics, balconies, air conditioners, air duct systems, technical pipelines, etc.

The material has high insulating properties, and therefore is suitable for thermal insulation of areas where both hot and cold products are transported.The use of penofol is associated with the thermal insulation of vehicles, tents or sleeping bags, on hikes.

Among the advantages of insulation with penofol, one should highlight:

1. Multifunctionality of the insulation.

When using penofol, additional work is not required to ensure vapor and sound insulation. Installation of additional membranes, films and other waterproofing materials is not required. In addition, penofol is installed both inside and outside the room, which ensures its moisture resistance and versatility of use.

2. Small thickness of the material - high thermal insulation characteristics.

With an insignificant thickness, penofol provides several types of thermal insulation at once, which is very important when arranging areas of a hard-to-reach nature. When installing insulation on the inner sections of the room, the usable area is practically not lost.

3. Availability of a wide range of products.

There is a wide variety of types of penofol, helping to choose exactly the material that is able to fully meet the individual needs of a building or object to be insulated. With the help of penofol, buildings are insulated both inside and outside the premises.

4. High strength and good quality.

Due to the use of advanced manufacturing technologies of the material, it provides minimal heat loss, amounting to only a maximum of four percent. Another advantage of this material is the fact that it is able not only to retain heat, but also convects it back into the room. Due to the special structure, moisture does not penetrate to its surface, and the application temperature is from -55 to +100 degrees. The principle of its operation is similar to a thermos, in warm weather it gives coolness, and in cold weather - so much needed warmth.

5. Convenience of operation and easy installation.

Since the insulation is in the form of a roll, it is quite convenient during the installation process and easily fits on any surface. In addition, for hard-to-reach areas, a special form is used, on one side of which a foil coating is applied, and on the other - a layer of glue. To install the insulation, you do not need to install additional supports or frame structures, it is lightweight and is fixed directly on the surface to be insulated. Use simple scissors to cut to size. One person is enough to carry out the work.

6. Environmental safety and reasonable price.

The composition of the material does not contain substances harmful to human health or the environment, therefore it is used without restrictions for internal insulation. Since additional hydro, steam and sound insulation works will not be required, using this insulation will significantly save money.

House insulation with penofol - installation features

This material is used as an independent insulation or in combination with other materials for the same purpose. In a wooden house, the insulation of a loggia with pelofolol is very simple and easy. Since it is glued to the wall before finishing it. In addition, floor insulation with penofol does not require the hiring of specialists, since this procedure can be easily performed on your own.

Use glue, stapler or nails to attach the material to the wall surface. For gluing seams, aluminum tape is perfect, which will help prevent damage to the integral structure of the reflective coating. Please note that the material is installed with the reflective side into the room, since it is this side that contributes to the return of heat to the room.

In addition, the use of foil-clad foam foam in the process of insulating air ducts and chimneys is widespread.This procedure is not difficult, since the material is particularly flexible and has an adhesive base, which is simply glued to them. Installation work is carried out at any time of the year and at any temperature, and no special equipment is required for their implementation.

To avoid moisture build-up, leave a small gap between the foam foam and the other material to which it is attached. The service life of this insulation is very high, since it consists of polyethylene foam, which is able to function normally for more than two hundred years.

Disadvantages of insulation with penofol from the inside and outside

Although penofol differs in a huge number of advantages that distinguish it from the background of other insulation materials, it still has certain disadvantages, which we will talk about later.

Penofol is characterized by insufficient rigidity, which makes it impossible to further finish the walls, immediately after its application.

The use of brackets for installing penofol is possible, but at the same time its thermal insulation function deteriorates. Therefore, it is better to use glue.

To ensure the full insulation of the walls of a residential building, it will be necessary to carry out complex heat-insulating works, which include the installation of several types of insulation together with penofol.

Tip: If in the process of work there was a deformation or cut of the foam, then to restore it, it is enough to process this place with aluminum tape.

To improve the thermal insulation properties, stack several layers of foam foam one on top of the other.

Penofol is an excellent heater for baths or saunas, since in these rooms it provides quick heating and long cooling of the walls. Please note that there should be a small gap on the side of the foil to prevent condensation.

Do-it-yourself penofol insulation

We will talk about the process of wall insulation with penofol in a brick house further. We suggest that you familiarize yourself with the instructions for carrying out thermal insulation work inside the premises:

1. The benefit of insulating brick walls with penofol is the use of a minimum of usable area, which is so important for owners of small apartments or houses.

2. It is better to insulate a brick house from the inside, since when loading it has a beautiful appearance, which penofol can spoil.

3. The primary implementation of internal thermal insulation involves the application of the film using liquid nails. The thickness of this layer is two millimeters. If there is electrical wiring, additional insulation is not required, since aluminum is an excellent conductor of electricity.

4. To fix the thermal insulation on the wall surface, you will need to build a wooden frame. Please note that you must leave a ventilation gap of at least two centimeters.

5. Using a construction stapler, lay the penofol on the walls and fix it.

6. In order to eliminate the formed gaps, fill with foam or silicone. To secure the joints - aluminum tape is enough.

7. The second wooden frame is also made of beams, two centimeters thick. Drywall is attached to it. Further finishing is carried out in accordance with the personal preferences of the owners.

Insulation of the balcony with penofol has a slightly different technology, and we will talk about it further:

1. The first step is to install the lining. Its thickness is about two millimeters.

2. Further, with the help of umbrella dowels, the penoflex is fixed on the wall surface. Its thickness is the same as that of the previous layer, and the diameter of the dowels is 0.6 cm. This material ensures fire safety and moisture resistance.

3. Pay attention to the corner areas, they should not contain joints, as these areas are prone to mold and mildew formation.

four.Use high quality metal tape to close the joints. It will also provide vapor barrier.

5. Penoflex is laid on the foam foam. To carry out the installation process, use self-tapping screws, 0.4 cm thick, and a laying step of half a meter.

6. To ensure a high level of thermal insulation and vapor tightness, use metal tape to seal the foam foam joints.

7. Make a batten from wood and dowel-nails. It will be required as an attachment to the base for finishing.

8. Carry out electrical work, if necessary.

9. Cover the areas on the windowsill, if any.

10. Leave an air gap of 1.5 to 4 cm to prevent moisture build-up. Install drywall and proceed with finishing the balcony.

Please note that all thermal insulation work is carried out exclusively after glazing the balcony.

The procedure for insulating external walls is more complicated and requires compliance with certain technologies, which we suggest to familiarize yourself with:

1. The first step is to thoroughly remove the facade coating.

2. Next, the installation of a wooden frame takes place, on which the insulation will be attached.

3. After completion of the work, penofol is installed and fixed on the surface with glue or a stapler.

4. The next step is the installation of wind protection and waterproofing. For these purposes, a superdiffusion membrane or OSB plate is suitable.

5. Then spacer bars are mounted, on which further facade cladding is performed.

6. In addition, you should not forget about the wind gap, which prevents the accumulation of moisture.

7. The final stage is the installation of facade coating, for example, siding.

Penofol insulation technology for internal walls

Depending on the characteristics of the room and the method of thermal insulation, the appropriate type of Penofol is selected. Some of them can be mounted autonomously (type B), others serve as waterproofing of a more powerful insulation (type A), and still others act as the basis of the heat-insulating layer (type C). This material successfully allows the surface to breathe without accumulating moisture. It relieves walls from the appearance of mold and mildew that arise after steam ingress.

Preparatory work before thermal insulation of walls with Penofol

Before you start laying Penofol, be sure to check the quality of the electrical wiring in the room. Unlike other thermal insulation materials, it contains aluminum foil, which is known to have good electrical conductivity. Protect the wires to prevent the insulation from coming into contact with bare cables. It goes without saying that the work surface is prepared - they clean off the debris, carry out cleaning with an emery cloth. If necessary, fill up the cracks with a filler solution. It is also advisable to buy a primer paint and paint over the wall, which will allow you to get a perfectly flat surface. Of the tools and devices for work, we need:

Well sharpened knife;
Furniture (construction) stapler with staples to it;
Ruler;
Level;
Pencil;
Construction trowel;
Hammer;
Working deep container for solution;
Emery cloth of varying grain size;
Screwdriver;
Roulette;
Dowels;
Electric drill.

Instructions for installing Penofol on the walls

Armed with the necessary tool and using the help of another person, they carry out the following actions:

Initially, a wall-mounted wooden frame is constructed. Its task is to enhance the effect of the use of heat-insulating material. For fixing the bars, dowels are taken, which are hammered no wider than 1 m from each other.
Penofol is fixed on the frame with a furniture stapler. For this, the material is cut into strips with a sharp knife. The strips do not overlap, but end-to-end, so that condensation does not form along the joint line.Seams can be glued with special tape.
After that, another frame is attached, at a distance of 2 cm. This is done in order to allow air circulation. Now it can be covered with cladding panels, putty or wallpaper on top.

A vapor barrier film is not laid, because the material itself is considered vapor-tight. However, it is not capable of replacing waterproofing. A common mistake associated with improper installation of insulation: some craftsmen mount Penofol directly on the ceiling or wall, leaving an air gap on only one side. This leads to a decrease in its thermal insulation characteristics. Important! When installing Penofol, its foil part must necessarily look into the room, and not at the wall. This is a prerequisite for additional heat reflection.

Finishing the walls

After laying the heat insulator, cover it with crate and wood boards on top, you can start finishing the surface. You need to start by leveling it: any defects that may interfere with the reliable attachment of the plaster or the gluing of a roll of wallpaper are removed. It is best to smooth out unevenness with emery, starting with coarse-grained and ending with fine sandpaper, which makes the surface even and smooth. Most often, a plaster solution is applied to the finished wall, which can then be painted or decorated in other ways. The most common are cement-based or gypsum-based plaster mixes. At the same time, gypsum is not subject to shrinkage over time, it has good plasticity and bonding properties. It does not require the use of a reinforcing mesh. If you don't have enough experience in plastering walls, you can purchase plaster signaling devices that will be limiters - they allow you to measure the thickness of the layer and protect against unevenness. After fixing the signaling beacons on the working surface, you can start preparing the solution. Take a bucket or other container, fill it with water about a third. Add the solution gradually and stir constantly to achieve a homogeneous mass. The mortar should be of such a consistency that it does not run off the spatula, and its density will depend on how thick the plaster layer should be. If the walls in the room absorb moisture strongly, they must be additionally moistened. For these purposes, a household spray gun is well suited. This is done so that the solution retains its moisture content, otherwise it will crack after drying. The plaster is applied to the wall by applying it with a spatula. If such skills are difficult to master at first, then you can apply the solution to a wooden trowel and level it on the surface. Alignment is performed from bottom to top. If plastering is carried out in the area of the slopes of window and door openings, then it is better to apply the solution with a slight overlap. Using the rule, you can remove the excess solution. Its sharp edge is directed perpendicular to the plaster beacons. You should start from the lower border. Gradually, the instrument is raised higher and higher and the excess solution is removed, throwing it up. After that, the final smoothing of the wall is carried out. This is done several times to achieve a flat surface. In order to make sure that the surface is flat, the rule is applied at different angles. The resulting bumps are scraped off with the sharp edge of the instrument. It remains to pull the beacons out of the wall with a screwdriver. Now you can grout or paint the plaster. On this, the insulation of the walls with Penofol from the inside can be considered complete.

Thermal insulation of wooden walls with Penofol

In this case, the work is somewhat different, since the wood itself is already a warm material.But, despite the fact that such a surface has a "breathing" ability, retains heat and contributes to the creation of a favorable microclimate, warm air can still seep into the street. During operation, the wood undergoes some shrinkage under the influence of natural and climatic factors. This causes the appearance of fresh cracks, cracks, and other unfavorable places. The tightness is broken, which leads to the need to apply a heat-insulating layer. Before carrying out insulation work on wooden walls, you need to make sure what kind of wood they are made of. This is due to the fact that different varieties and types of wood differ in different characteristics in terms of thermal insulation. All this leads to the fact that the cost of insulation may be different. It is the lack of external insulation that leads to the need for internal thermal insulation of the walls. Penofol in this case is perfect, especially if you combine it with other materials. Insulation of a wooden house is carried out according to the following algorithm:

Insulation of wooden walls from the inside with Penofol should be started by filling up the cracks and gaps that are naturally formed in the wood. It is recommended to pay special attention to checking the joints, window frames, door frames, corners.
Making a frame for a heat insulator for wooden walls is optional.
If Penofol sheet with one-sided foil is used, then it is the side with the foil that should face the crate, that is, inside the room.
A sharp knife is used to cut the strips.
The strips are attached using special staples and a powerful construction stapler. At the same time, they should be in close contact with each other so that there is no free space between them.
To fix the joints, they are glued with aluminum tape. This will provide an even and uniform reflective surface.
The preservation of the air gap is a must for effective insulation and the absence of condensation. The air space must flow between the material and the wall.
On top of the insulator, wooden bars are stuffed, which will serve as the crate. Chipboard sheets or plastic panels can be attached to them. The final finishing is the same as for concrete walls.

Note! It is necessary to carry out work on the internal insulation of a wooden house after the final shrinkage of its walls and foundation occurs. This usually happens no earlier than a year after the completion of all construction work. How to insulate walls from the inside with Penofol - watch the video:

The attractiveness of Penofol as a heater is largely due to its unique properties. However, one should pay tribute to its value, which fluctuates in ranges below the market average.

The technology of installing penofol to the ceiling on glue

The use of an adhesive solution reduces the installation work of penofol to the ceiling from inside the room. This method does not require specific fasteners and is easy to use. Due to the light weight of the material, there is no need to calculate the amount of adhesive. In the event that it is planned to use penofol as the only insulation, then it is recommended to choose a product with sufficient thickness.

Step-by-step instruction:

Cleaning the ceiling surface from old plaster and coating. A flat plane should be achieved, and, if necessary, treated with sandpaper and plaster.
Pathogenic microorganisms should be scraped off with a spatula. Then the treated area is doused with a hot stream of air and treated with antiseptic solutions.
If grease and oil stains are present, wipe with solvent.
Cracks, chips and gaps in the ceiling are sealed with a mortar of cement and sand.
If the ceiling is made of wood and there are gaps, then they are filled with caulk, large cracks are eliminated with tow and PVC film.
Wood elements are covered with protective anti-flammable agents and anti-rot. Each new layer is applied after 100% drying of the previous one.
All sharp protruding elements that can damage the integrity of the foil are eliminated.
Further, the ceiling is treated with a primer suitable for the composition of the adhesive for fixing the foam foam. This step is mandatory because allows to improve the quality of adhesion to the surface.
Glue preparation. In the event that a material with a sticky base is chosen, then it is enough to remove the protective film and then carefully attach the penofol to the ceiling.
If the material is chosen as usual, then a thin layer of adhesive solution is applied to its surface. In this case, the work is carried out evenly, without gaps. Thoroughly coat the edges and incubate for 1 minute.
Then, the penofol sheet is pressed against the ceiling or the first layer of insulation. Gently smoothes until it sticks. The joints are fixed with reinforced tape or silicone-based sealant. The joints should not be left unprocessed.

During installation, it is necessary to ensure that the canvas ends in the corner of the room. It is forbidden to overlap the material. Additionally, you should control the places of contact between the wiring and foil. This is because foil is an excellent current conductor. In view of this, you should make sure of the insulation of the wires close to the insulation.

In conclusion, decorative work is carried out. For example, this can be the installation of a suspended ceiling structure.

Criterias of choice

To perform high-quality insulation of the floor with foam foam, as well as walls and ceilings, it is necessary to choose the right insulation. To do this, you should be guided by the following criteria:

for ease of installation, it is recommended to choose a material thickness of at least 5 mm;
when insulating steam rooms, boiler rooms and industrial premises with elevated temperature and humidity, it is better to abandon the use of foam foam in favor of multilayer materials with increased moisture and heat resistance, for example, folded polypropylene;
it is imperative to pay attention to the quality of the polishing of the foil and the type of metal from which it is made, since the amount of reflected thermal energy will depend on this, and, accordingly, the efficiency of the material;
when buying the required amount of penofol, it should be borne in mind that the rolls are sold not by running meters, but by the coverage area, which varies within 9-18 m2;
it is recommended to either refuse to buy a sewn insulation, or carefully study the technology, as it was done (physical or chemical method), since this criterion has a significant effect on thermal conductivity;
it is worth paying attention to branded manufacturers who can guarantee the declared technical characteristics.

Floor insulation with penofol

What is good about insulation with this material?

In addition, the insulation of a wooden house with penofol provides additional noise insulation and wind protection, since the material has a high noise absorption coefficient.

Also, the advantage of the material is that it can be applied not only to new buildings. Penofol wall insulation can also be mounted on the walls of old buildings and does not require temporary cessation of their use.

Insulation with penofol from the outside implies the device of the so-called "pie" - a structure consisting of several layers.

Benefits of penofol - debunking myths

Manufacturers and sellers of penofol attribute wonderful thermal insulation characteristics to this insulation, which is actually a myth.

Wiring diagrams with air gaps, one of which we described at the beginning of the previous section, can also be considered as misleading the buyer. How the manufacturer proposes to insulate floors and roofs is shown in the figures:

In fact, the presented schemes are nothing more than another way to improve the thermal insulation of external fences using air gaps, since the intrinsic resistance to heat transfer to penofol is categorically not enough.

This can be easily verified using the best thermal conductivity from the technical data sheet, 0.037 W / m2 ° C. Then we take the canonical formula and determine the thermal resistance of a material with a thickness of 4 mm:

R = δ / λ, where:

δ - thickness of penofol in meters, taken 0.004 m;
λ is the coefficient of its thermal conductivity, equal to 0.037 W / m2 ° C.

We get R = 0.004 / 0.037 = 0.11 m2 ° C / W. Now we look at the comparison table, which is presented on the same resource as the technical data. It says that 4 mm of foam foam can easily replace 77 mm mineral wool or 46 mm expanded polystyrene.

So, for comparison, it is necessary to determine the thermal resistance of a layer of mineral wool 77 mm (its thermal conductivity is 0.05 W / m2 ° C):

Rminvats = 0.077 / 0.05 = 1.54 m2 ° C / W, which is 10 times more than foamed polyethylene.

Hence the conclusion: the presented comparative table is a pure fake. The data given in it are unreliable, and although the material is a good insulation, it is not better than others. The reason is that it is too thin, although in terms of thermal conductivity it is equal to extruded polystyrene foam.

Against this background, all other benefits of penofol pale. True, there is another myth - about the reflection of infrared heat back into the room thanks to the foil surface. But none of the manufacturers explain what the foil will reflect behind the interior trim. After all, infrared radiation spreads through an open space, it will not pass through drywall or other obstacle.

What is really good about penofol is its low cost and ability to act as a vapor barrier along with other insulation, as evidenced by reviews on the forums. In addition, it is easy to install, and the process is not time-consuming. You can also note the durability of the insulation, reaching 50 years, provided that it is located inside the building, and not outside. By the way, it is better not to use penofol for external wall insulation, there it will be of little use. You should not take it for thermal insulation of a bath, like any polymer, when heated to 100 ° C, the material will begin to emit harmful substances.
