New building materials appear on the building materials market every year. This is due to the development of technologies used in construction. So, relatively recently you can find foil penofol on the market. In this article we will learn about all the features of penofol as a heat insulator. As a result, you will be able to fully use it, and, most importantly, for its intended purpose.
Foil penofol is a multilayer material. Penofol falls into the category of reflective insulation. So, if we define the main function of foil penofol, then it comes down to protecting a particular structure from:
As you can see, foil penofol is a universal insulating material. It has the following properties:
In the process of producing foil penofol, it acquires all these properties to the fullest.
Foamed polyethylene is used as the basis of foil penofol. Polyethylene has closed pores. These pores, in turn, are filled with air. It is worth noting that polyethylene foam is used with different structures, densities and thicknesses. Based on the purpose for which the foil penofol will be used, it is covered with aluminum foil on one or both sides. The peculiarity of this foil is that it has the ability to reflect up to 97% of a particular energy. This is achieved through pre-polishing.
Aluminum foil is applied to penofol by means of warm welding. Thanks to this, the material acquires a homogeneous structure. As for the thickness of foamed polyethylene, it can range from 2 to 10 mm. If we talk about aluminum foil coatings, then its thickness ranges from 12 to 30 microns.
Important! If your region has a harsh climate, then you can use foil penofol with a maximum thickness of 40 mm.
The principle of action of penofol comes down to the discovery of James Dewar, known in the twentieth century, also known as the “Dewar Vessel”. Through a series of studies, he found out that this or that substance has the property of resisting heat transfer. He concluded that the material is unable to completely stop heat transfer, but only slow down the transfer rate. Moreover, the substance has the property of accumulating thermal energy. As soon as saturation occurs, the substance begins to give off heat.
James Dewar conducted a series of experiments during which he identified substances that could not absorb thermal energy, but, on the contrary, reflect it. For example, among such materials he highlighted:
As a result of the experiment, he discovered that all these metals reflect thermal energy up to 99 percent. However, such reflectors are also excellent conductors. Therefore, it was decided to use them with thermal insulation materials. If everything is simply explained, then a household thermos has a similar principle of operation. So, thanks to this discovery, it became possible to start saving on energy during the heating season. Also prevent overheating of certain structures in summer time of the year.
Having familiarized ourselves with the main features of foil penofol, we will consider all its positive and negative sides. Among the positive aspects of foil penofol, the following can be noted:
Although this thermal insulation material has a number of bright positive aspects, it is worth noting some of its negative points. Here are some of them:
Foil penofol is divided into three main types:
These types of products differ in their technical characteristics. So, type A means foil penofol, which has a foil coating on only one side. He can be found on domestic market more often. As for type B, this is a product that has a foil coating on both sides. Its peculiarity is that it is used for thermal insulation attic floors, floors, walls, ceilings, baths, saunas, pipes, etc. Well, the third type C is different in that on one side there is adhesive coating, and on the other a reflector.
Important! The presence of an adhesive surface allows installation without additional equipment. This greatly simplifies and speeds up the installation process.
Foiled penofol has the following technical characteristics:
Having such excellent technical characteristics, foil penofol has found relatively wide application. Thus, it is used in the construction of capital buildings or during repair and finishing work. In most cases it is used as thermal insulation bath rooms, saunas, refrigeration chambers, private houses, apartments and more.
Also used as a treatment for various structural elements, for example, when finishing internal or external walls, for waterproofing, vapor barrier and thermal insulation of roofs, ceilings and floors, window systems and shielding of heating batteries.
So, here we are familiar with the main technical characteristics of foil penofol. As you can see, he is very popular. We hope that this material was useful to you and that you were able to get answers to your questions. In addition to this material, we offer viewing of prepared video material that can fill in all possible gaps. So, having full information, you will be able to use foil penofol correctly, and, most importantly, for its intended purpose.

Modern foil penofol has an important advantage over its competitors. This material consists of foamed polyethylene and a layer of foil. This design makes it possible to provide double action— prevent convection due to polyethylene foam and protect from thermal reflections using an aluminum insert. Such technical characteristics have expanded the scope of application of the material. This insulation is used inside and outside walls, with a maximum thickness of 10 mm guaranteeing highly effective thermal insulation.
The advantages of foil penofol include:
But foil penofol has certain disadvantages.
Foiled penofol has found wide application, since its technical characteristics make it possible to achieve different results in certain types of insulation work.
Today, insulation using foil foam foam can be carried out in the following buildings and structures:
Excellent characteristics provide excellent result when isolating various objects, ranging from simple walls and roofs, ending with the protection of air ducts and your own bathhouse.
Proper use of foil penofol allows you to reveal all its characteristics and show technical features, organize high-quality insulation for walls and more. Work can be carried out inside and outside. This is what forms the nuances of installing foil foam foam.
To organize insulation from inside the walls, the sequence of work is as follows.
We figured out how the insulation is installed from the inside. But we advise you to further study the photo instructions and watch training videos. They will allow you to choose the right material, glue, prepare tools and make insulation with your own hands.
So, you visited the Leroy Merlin store, purchased glue, took foil penofol 10 millimeters thick and are planning to insulate the walls from the outside. If you have to work on insulating air ducts, we recommend using self-adhesive foam foam options. They are easier to install than with glue. In general, when choosing between self-adhesive products and penofol for glue, preference should be given to the former. Especially if this is your first experience working with foil insulating material.
For external insulation, work is performed as follows:
Availability on the market insulating materials foil penofol allows you to significantly simplify the solution to the issue of heat, hydro, and vapor barrier. With a thickness of only 10 millimeters, and the thickest material, it has identical characteristics to much thicker counterparts.
In any case, the choice is always up to the client. But the presence of impressive advantages and rather controversial disadvantages makes self-adhesive foil penofol one of the main market leaders. Choosing products with a thickness of 5 mm, 10 mm or other parameters depends on the specific situation.
The construction of any object is impossible without the use 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. The result is high-quality and inexpensive insulation of premises.
Penofol is one of the most popular and widespread types of insulation.
Penofol is usually classified as a reflective insulation product. It was developed specifically for protection various surfaces from such negative factors, like cold, moisture and steam. Over the years of its production, the product has been improved. As a result, it acquired not only excellent thermal insulation properties, but also protection from water and sound. Its structure contains several layers:
This material belongs to the category of heat reflective thanks to the foil, which is attached to the polyethylene “foam” 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.
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 important parameter The thermal conductivity of this solution is quite comparable to that of 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% of 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 penetration inside electromagnetic radiation.
Main Application this insulation– roof, walls, bathhouse, loggia, where there is a layer for reflection 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:
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.
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 used in the house repair work. This solution is most effective for thermal insulation:
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.
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:
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 allows you to pick best option to solve the problem that has arisen. Foil insulator is good decision when it is necessary to perform high-quality thermal insulation of an 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.
Penofol, which has no competitors, has excellent characteristics. Its flexibility allows it to fit perfectly on any surface. Among all the diversity modern materials penofol has gained the highest popularity. Penofol, like any construction material, has its pros and cons. In this article we will analyze the advantages and disadvantages of penofol and its scope of application.
When renovating 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 “sound” and “steam” don’t particularly bother developers, then everyone thinks about heat.
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 preference to this particular material.
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 the average buyer will be interested in the modulus of elasticity or other technical details of this material. Therefore, we will consider the types, scope of application, installation basics, feasibility of use, advantages and disadvantages of penofol.
Penofol is offered by manufacturers of the following types:
In the first option, to preserve heat, the foil side of the penofol should be facing toward the room. The use of penofol type “B” allows you to prevent excessive heating of the room in the summer, and to retain heat in the winter. The third option is used for thermal insulation of surfaces in hard-to-reach places.
Manufacturers also offer other types of penofol: 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 run the air conditioner in the summer or the heating boiler in the winter.
It is worth noting that for thermal insulation external walls In buildings, penofol is used as additional insulation, which, first of all, protects walls from moisture and reflects thermal energy.
Unfortunately, it is not entirely advisable to use devices that pierce it to attach penofol. Sloppy work can worsen the thermal insulation qualities of this insulation. For this reason, penofol began to be produced with a self-adhesive surface.
The advantages of penofol are determined by the following qualities:
TO shortcomings penofol can only be attributed to its softness. It is enough to put a little pressure on the material and it will bend, so finishing penofol 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 is the most modern thermal insulator excellent option. Penofol protects not only from cold, but also from extraneous noise and moisture. At the same time, the loss of free space in the room and the consumption of thermal insulation materials is minimized. This fact will please any owner.

How to choose a gas boiler?
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 miraculous properties to foamed polyethylene. Let's look at how Penofol is used correctly and why owners sometimes experience losses with this material...
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 pasted layer of aluminum foil reflects infrared radiation, preventing him from escaping from the heated house to the 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.
There are:
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:
Apparently, such a high value for a thin layer of insulation was 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 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 radiation absorption by structures, and also, apparently, also adding the resistance of 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.
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...
