Penofol, which has no competitors, has excellent characteristics. Its flexibility allows it to fit perfectly on any surface. Among all the variety modern materials penofol has gained the highest popularity. Penofol, like any building material, has its pros and cons. In this article, we will analyze the advantages and disadvantages of penofol and its scope.

When repairing or building a house, almost all surfaces are finished: ceilings, floors, interior and exterior walls. This, as a rule, is the insulation of surfaces, as well as their steam, sound and waterproofing. But, if the "sound" and "steam" do not particularly bother the developers, then everyone thinks about the heat.

The construction markets offer a huge range of thermal insulation materials, the use of which is determined by their technical characteristics. New material - Penofol appeared relatively recently. Let's try to understand whether it makes sense to give our preference to this particular material.

Penofol - what is it?

Penofol is a multilayer material based on polyethylene foam. The base is covered with a thin layer of aluminum foil. Penofol is a type of reflective insulation. It is unlikely that an ordinary buyer will become interested in the modulus of elasticity or other technical details of this material. Therefore, we will consider the types, scope, installation basics, expediency of use, advantages and disadvantages of penofol.

What types of penofol do manufacturers offer?

Penofol is offered by manufacturers of the following types:

  • Type "A" - the base is covered with foil on one side.
  • Type "B" - double-sided coating with a protective layer.
  • Type "C" - foiling on one side, self-adhesive layer on the other.

In the first option, to preserve heat, the foil side of the penofol should face the room. The use of penofol type "B" allows to prevent excessive heating of the room in summer and to keep warm in winter. The third option is used for thermal insulation of surfaces in hard-to-reach places.

Manufacturers also offer other types of foam: with reinforcement, perforation and a number of other features. In any case, the principle of action of penofol creates the effect of a thermos. In a room insulated with this material, you will not have to "drive" the air conditioner in the summer, and the heating boiler in the winter.

Where is Penofol used?

  • The material is perfect for insulating walls (external and internal), floors and roofs of buildings.
  • Indispensable for thermal insulation of ventilation systems and air ducts.
  • It is used for insulating cars and mechanisms.
  • Ideal for balconies and loggias.
  • Installed behind heating radiators.
  • Serves as a heat insulator for pipes and pipelines, but on top of mineral wool insulation.
  • This material is very convenient for arranging thermal insulation for temporary huts, modules for trade, stalls.

It is worth noting that for thermal insulation of external walls of buildings, penofol is used as an additional insulation, which, first of all, protects the walls from moisture and reflects thermal energy.

What are the rules for installing penofol?
  • Before starting the installation of the insulation, any surface is cleaned, its irregularities and cracks are eliminated.

  • This material is absolutely waterproof. Therefore, there must be a free air space of at least 20 mm between penofol and additional structural elements. For this, a frame made of wooden slats, to which penofol is subsequently attached.
  • Aluminum is a good conductor of electricity. therefore contact of penofol with uninsulated or low-quality electrical wires is unacceptable... Before the beginning installation works the quality of the wiring is carefully checked.

  • Penofol is cut into strips of the required length using a knife. Next, using a furniture stapler, the insulation is attached to the wooden frame. The stripes are applied end-to-end. Fastening of penofol with an overlap is unacceptable... If steam forms, accumulated condensation will drain along the overlap lines. The joints of the insulation are glued with aluminum tape.
  • Because an air space of 2 cm should be on both sides of the penofol, then it is set again wooden frame... The slats of the second frame are aligned with special care, because the finishing material will be attached to this structure.

Unfortunately, for attaching penofol it is not entirely advisable to use devices piercing it. Careless work can worsen the thermal insulation qualities of this insulation. For this reason, penofol began to be produced with a self-adhesive surface.

What are the advantages and disadvantages of penofol?

The advantages of penofol are determined by the following qualities:

  • the small thickness of the material, however, provides decent thermal insulation of the premises;
  • ease of installation, when installing penofol it is not required professional tools, the material does not crumble or break;
  • environmental friendliness, the components of penofol are used even for storing food;
  • waterproofness;
  • fire safety;
  • is an excellent noise and waterproofing agent;
  • ease of transportation, thin material is rolled into compact rolls;
  • affordable price.

TO disadvantages penofol can only be attributed to its softness. It is enough to press a little on the material, and it will bend, so finishing the foam foam with wallpaper or plaster is impossible.

Having studied the main characteristics, advantages and disadvantages of penofol, we can conclude that the insulation of buildings and structures with the most modern heat insulator is an excellent option. Penofol protects not only from cold, but also from extraneous noise and moisture. At the same time, the loss free space premises and consumption of thermal insulation materials are minimized. This fact will delight any owner.

The name Penofol has become so popular that this foamed polyethylene foam is sometimes used and where it is not necessary to the detriment of the result with monetary losses. Sellers who, for the sake of sales, attribute to foamed polyethylene, contribute to the hype popularity miraculous properties... Let's consider how Penofol is applied correctly, why sometimes owners get losses with this material….

What is Penofol

Expanded polyethylene with foil is a soft and resilient roll material, often from 3.5 to 10 mm thick, for use as a substrate, vapor barrier, wind barrier, insulation layer.

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

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

It is produced with a thickness of 3 - 10 mm, more 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, lathing. Convenience and ease of use, as well as low price, contribute to popularity and ... misapplication.

Thermal insulation qualities of Penofol

It should be noted that when compressed by 2 - 3 times of the initial thickness, air is partially displaced from the material, the coefficient of thermal conductivity increases significantly. At the same time, a decrease in the thickness of the layer leads to a proportional decrease in the resistance to heat transfer. This means, at least, that Penofol, as a heater, 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 - 1.175 - 1.362 m2C / W.

Apparently, such a high value for a thin layer of insulation was obtained by adding the heat transfer resistance of directly foamed polyethylene with a thickness of 5 - 10 mm - only 0.15 - 0.3 m2C / W, as well as adding here the heat saving from foil (a barrier for radiant heat), which completely depends on the power of radiation 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 the resistance of the "closed air gap»Construction, which can actually reach 1.0 m2C / W, for example, in a glass unit.

Nevertheless, the obvious fact is that Penofol really insulates, it remains only to apply it correctly.

Basic rules for the use of Penofol


Where and how Penofol is mainly used in practice


Experts warn. The large-scale application of shielding with conductive foil can disrupt the natural magnetic background, increase (decrease) electromagnetic tension, disrupt the operation of transceiving devices, which cannot be called useful and correct ...

Examples of incorrect and dangerous use of Penofol

  • Laying Penfall 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 layer of insulation in structures that must be insulated in accordance with the standards - in the floors, in the roof, in the walls. In this case, users are usually guided by the assurances of sellers that the material replaces "5 centimeters of foam" or "6 centimeters of mineral wool". As a result, without the main insulation layer (in most cases, it is economically optimal from 10 cm of effective insulation ...), the structures remain cold.
  • Overlaying from the side of the living space directly on Penofol, without leaving an air gap, finishing panels, wood trim, wooden structures, which entails moisturizing of the finish, the development of mold, rotting of wood due to condensation accumulated on the vapor barrier-insulation. After a year of such operation, according to the owners, Penofol is “black with mold”.
  • Gasket inside panel structures on the foil side of the wiring.
  • Docking of Penofol sheets with leaving gaps, which, in addition to a general decrease in insulation, in some structures leaves greater air permeability (drafts), which completely eliminates the presence of an insulation layer.

If you closely follow the market of building materials, in particular, heat-insulating materials, read various reviews, you could not help but notice the appearance of a new, high-tech thermal protection means, penofol. This material can be classified as one of the types of reflective insulation, consists of several layers - a base and reflective foil.

The basis of penofol, in fact, which gave it its name, is polyethylene foam, which has a different structure and density indicators. The foil is applied to the substrate by heat welding.

The base of the penofol has a thickness of 0.2 to 1 cm, a foil thickness of 20 microns, a reflection coefficient of 97%. For use in harsh climates, manufacturers produce a special type of foam foam 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 give you a certificate that the first spacesuits for NASA astronauts were made using penofol.

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

This modern technological material creates a barrier to direct heat transfer due to polyethylene foam, 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 \u200b\u200byour room.

Foiled Penofol: specifications 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 0.001mh / mhchh Pa

Foil penofol finds application both as the main insulation and as an interlayer of the thermal insulation system.

The photo below shows an example of foil-clad foam foam with a thickness of 10 mm.

Foil penofol


Foil penofol and its application

It can be used when:

- insulation of walls inside and outside the premises, attics and basements
- water and vapor barrier of saunas and baths
- roof insulation and
- water pipe insulation
- heat reflection of heating batteries
- noise insulation and insulation of ventilation and sewer systems
- car insulation and noise insulation
- arrangement of residential and commercial trailers
- insulation of cold rooms

Foil-clad penofol has its own advantages and disadvantages, which will have to be considered when choosing thermal insulation. Immediately, I note that there are much more advantages from the use of penofol and I will start with a fairly moderate price in comparison with other materials.

What other benefits does the consumer get:

- 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
- material is hard to reach for rodents

The main disadvantages I'll take:

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

- some inconveniences when strengthening: needed special formulations glue, etc.

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

We check penofol strength - watch the video:

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

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

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

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

3. Type C - self-adhesive penofol.
Its outer side is covered with a layer of aluminum foil, and the inner side is covered with polyethylene foam with contact adhesive.

4. ALP type.
A plastic film is glued on top of the aluminum layer. This type of foam is called laminated. It is effectively used for the needs of rural areas.

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

6. Super NET which means "network".
It is used to isolate networks.

7. Penofol AIR for air ducts.

If you see penofol brands on the counter Penofol-2000, be aware that this insulation is the most inexpensive type of penofol, i.e. worse in all technical characteristics and, above all, in strength.

The main methods of installing foil-clad penofol

- the reflective layer of the material is always laid in the direction of the heat transfer source
- 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 glued with foil tape
- the most important thing: remember that foil is a very good conductor electric current, carefully check the insulation of the wiring

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

Penofol insulation of walls from the inside

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

Penofol insulation of walls from the inside


Procedure:

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

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

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

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

- glue the tip with aluminum adhesive tape

- nail a river frame or a layer of plywood 2 cm thick onto the foam foil

- put drywall or chipboard on top of the crate

In order to insulate the ceiling with penofol, cut it and attach it along the wall, starting from the middle. When you get to one corner, nail the side closer to the wall. Further from the middle, move in the opposite direction and fasten the strip further.

Then move perpendicular to the material web to the corners, while all the time smoothing the penofol along the ceiling.

I want to remind you that penofol is a very unpretentious material to use. When installing it, you can do nothing to treat the surface and not even pre-prepare it for work.

It should be taken into account that steam entering the building structure 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 indoor installation.

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

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

For insulation work outside the house, use perforated foam foam, it will protect the walls from precipitation and wind, and also keep the area of \u200b\u200byour home intact, without reducing it.

Penofol insulation of walls outside


Insulation is mounted between the wall and the cladding of the house. Better work to insulate the walls outside in summer, because there are no sharp fluctuations in temperature and the walls are already dry enough.

The procedure for insulating a house with penofol outside

- remove all coatings from the walls and perform an 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 the penofol, remembering to leave a gap for air

- glue all joints with foil tape

- mount the outer frame and start covering the room

So, today we have studied in sufficient detail the properties of penofol, one of the most popular modern heat insulators. If you want to protect your home not only from cold and moisture, but also from noise, if you are interested in preserving the usable floor space as much as possible and still being in financial gain, give your preference to this excellent material.

We compare penofol with other analogues, watch the video

Foiled penofol is a new environmentally friendly heat-insulating material, very soft, lightweight and fairly easy to install. Does not have any odor, is not toxic.

It is made of aluminum foil applied to a polyethylene base with special equipment.

Has a number of advantages over fiberglass and epispatic materials. Safe for the ecological environment and harmless to humans. Also resists ultraviolet radiation that can penetrate sheet metal, concrete, wood and other general thermal insulation materials.

Self-adhesive penofol is a new insulation coating that has not only good heat and waterproofing, but also protection against different types radiation. The material has received a wide vocation in the construction industry thanks to the latest technology production with one-sided self-adhesive side, which significantly increases the speed of installation of such a heater

Can be installed on the roof and hold over 80% internal warmth buildings, protects the walls, prevents the obvious consequences of thermal shock in summer period and sudden frost in winter. Penofol has a thickness of 3 mm to 10 mm, roll width is from 20 mm to 120 mm. The common sizes of self-adhesive polyethylene are: width 58 cm, thickness 3-5 mm.

Shielding properties, moisture protection, retain heat and provide overall energy savings - all of this is influenced by the thickness of the foam

.
Penofol has characteristics similar to foam boards, while its dimensions are much smaller, the coating is very thin. Let's consider a little the basic properties of penofol:
  1. Odorless and toxic.
  2. Lightweight, soft, dust-free.
  3. Easy to install.
  4. Heat reflection, heat insulation, sound insulation, anti-radiation, anti-vibration and shielding.
  5. Sun barrier, waterproof, energy saving.
  6. Retains heat in winter and cool in summer.
  7. Saves heat and electricity.

Penofol specifications:

  • resistance to extreme temperatures from + 0 ° С to 150 ° С;
  • due to the "mirror" reflection of the surface, thermal air flows arise, which provide convection in the room;
  • uniform distribution of heat throughout the heated space;
  • thermal reflection coefficient up to 95%;
  • waterproof material that expands the range of use of insulating foil (walls, ceiling, floor);
  • ease of installation allows you to independently perform installation work;
  • the thermal conductivity of penofol is 0.037-0.051 (for various types).

Penofol insulation has technical characteristics that are ideal for the implementation of thermal, hydraulic and steam insulation. Penofol is good for insulating an apartment, a private building, and for storage facilities, hangars, workshops.

The properties of self-adhesive polyethylene foam can be used to shield rooms with high humidity: baths, showers, changing rooms in pools, saunas. Those. this material is very much in demand during construction work on the insulation of various objects, where there will be constant moisture or steam.

In addition, polyethylene foam perfectly absorbs sound waves and mechanical vibration. These properties are used in the construction of operator cabins (for example, boiler rooms or steelworks). The advantage of using penofol in this case is simply ideal: it eliminates sound, absorbs vibration, and creates a heat shield.

Foil self-adhesive penofol is often used for insulating boiler equipment, shielding various cables, and insulating pipes. Such insulation will be useful when laying networks below ground level, where there is high humidity, and the insulation material does not absorb moisture.

Penofol types

There are three types of penofol, depending on the version, thickness and various thermal characteristics. Penofol insulation, depending on the type, is designated by Latin letters: A, B, C, which are indicated on the package.

First type A Is a polymer insulation different thicknesseswith foil applied on one side. Aluminum foil is present on all types of insulation, but also differs in thickness. This material is widely used for complex thermal insulation of various construction projects. In conjunction with penofol type A, glass wool is used or mineral wool... Below is a photo of penofol with foil on one side.

The latest innovation in the production of polymer insulation is perforated foam foam. Such material can "breathe" due to the large number of holes. Often used for insulation wooden structures, for example log cabins.

Next type B - covered with foil on both sides. Thus, the maximum effect of insulation of any room is achieved, both from the inside and insulation from heat losses from the outside. This type of polymer is used for insulation load-bearing structures attic, basement, floor and wall waterproofing. In heat engineering and housing, such material is used for thermal insulation of transit pipelines in the basements of multi-storey residential buildings or elements of a heating system with a roof wiring. The photo clearly shows the difference from type A.

Self-adhesive penofol belongs to type C. As in the previous types, foil is applied on one side of the polyethylene foam, and on the other side a thin layer of glue covered with a film. Depending on the size of the foam roll, this type is very easy to mount on almost any surface, which increases productivity and saves time. For preparatory work it is only necessary to cut the roll into strips of the required width or square (rectangular) segments. It is easy to cut with scissors and does not require any special working skills.

Photo of self-adhesive foil penofol:

There are several more types of penofol that have a narrowly targeted application or are not very popular in construction.

R type - this is a foil-clad one-sided foam foam with a relief pattern on an aluminum surface. Absolutely repeats type A, but is often used as a decorative element for finishing works or multi-layer insulation, where it is necessary to create an air gap.

Penofol without aluminum foil also exists, does not have a specific type, the builders call it a "laminate underlay". Quite cheap material, mainly used for thermal insulation of flooring.

Specific insulation materials: type ALP - heat-insulating material with a high degree of reflection, used in animal husbandry for insulating incubators; Penofol type NET - similar in characteristics to type B, is produced in narrow rolls or coils of strips of a certain width. Used for pipeline insulation.

Penofol 2000 type C can often be found on the building materials market. It has reduced heat-technical characteristics of type C, the quality of the glue leaves much to be desired. Before buying, you should think about whether such minimum properties will be enough for high-quality thermal insulation. It is important to remember that the miser pays twice.

We just lay the insulation

Penofol is widely used. For the installation of insulation with a foil layer, it is necessary to perform a number of preparatory operations, depending on the type of work and the material that will be insulated.

The use of penofol in wooden house as a heater is the most common. For high-quality adhesion, it is necessary to pre-treat the surface with a grinder.

Fastening to the penoplex penofol is carried out using polymer glue, which is applied to a denser surface.

The misconception is that penofol is attached to a soft surface using staples or an industrial stapler. This will damage the integrity of the coating and the material will lose its insulating properties.

It will be easier to glue the isolon on the metal if you use a self-adhesive insulation. but in a simple way will press the insulation to the metal surface with rigid foam plates.

The main thing is to follow the basic rules for installing penofol: do not use in flooring under concrete screed, do not staple or wire, do not use a stapler, do not tape the joints.

For high-quality installation, overlap one sheet on another, accurately measure the required length to save material, always lay out the insulation in a thin layer, without forming an "accordion". For the best possible organization of butt joints, use special adhesive foil.

We glue penofol to various surfaces

Insulating foil material without a layer of glue applied to it is much cheaper than self-adhesive foam foam. Penofol glue may be needed if the budget for insulation work is limited.

In order to fix penofol on a sheer surface, you will need a moisture-resistant glue, because initially, such insulation provides for the presence of moisture and ways to isolate it.

This adhesive, which quickly hardens without releasing water, can be applied to the entire surface of the insulation or the wall. The insulation function is ensured along the entire perimeter, even in the event of temporary or permanent exposure to moisture from the outside. Also, such glue is not susceptible to mold and various fungi.

This adhesive does not contain solvents: it consists of three parts by weight of a liquid component made from a polymer-bitumen emulsion and one part of a cement-based powder component. The adhesive mixture allows you to easily attach the insulation to the surface of brick, concrete, limestone, tiles.

disadvantages

The main disadvantage of penofol as an insulating material is that it practically cannot be used as the main insulation. In 90% of cases, for installation, you will need to stuff the film onto an existing frame, in the cells of which there is the main heat-insulating material (for example, foam).

Penofol surface cannot be processed - mechanical stress will break the thin aluminum coating.

Doesn't keep its shape. Such insulation should either be laid between several layers of dense material, or sheathed with a facing layer.

Low rigidity and density. The material is very soft, it breaks quite easily from any mechanical impact.

Insufficient thermal insulation properties for use as the main insulation.

May cause a short circuit, when the foil film comes into contact with faulty electrical wiring.

Analogs

Like all construction Materials, penofol has analogs, which include the following heaters: alufom, isofol, styzol, energoflex. Tepofol or penofol with a metal coating is also a common analogue. Adheres very well to any metal surface.

Each of the materials has its own, albeit insignificant, but features: density, shape, coating, etc. Some have multiple layers of metal film and some different types used plastic for foaming. Often there is a type of insulation, where the foil is located between two layers of oilcloth.
