Penofol is a modern insulation of foil polyethylene foam. This reflective thermal insulator acting on the principle of thermosa. We will talk about the technical characteristics of the material, the benefits and its application further in the article.
Penofol - Rules and Features of Production
The Penofol was invented in the United States as one of the elements of the space skuffard, later he was used to use and in everyday life. Today, foil foofol is a roll material that combines the thermal insulation characteristics of foamed polyethylene and foil. It can have a different structure and density, and its thickness varies in the range of 2-10 mm. The folgized layer of material is created from aluminum foil, the purity of which should be more than 99.4%. The foil is applied to the base of polyethylene by means of a heat welding, the thickness of this layer is about 20 microns.
To understand the principles of functioning of modern insulation, it is necessary to understand the procedure for transferring heat between objects. There are three types of heat transfer:
- 1. Convection. Heating thermal air that transmits heat from one object to another.
- 2. Condition. Direct transmission of heat between objects.
- 3. Thermal radiation. Heat transmission through electromagnetic infrared waves.
Almost all existing insulation materials are capable of preventing only one of the described heat transfer options. Unlike them, the foam works combined, polyethylene foam in its composition prevents convection, while the foil provides high-quality thermal reflection (up to 97%). Such a structure of the material provides it to heat transfer resistance at the level of 1.355 units with a thickness of thermal insulation in 10 mm. For comparison, the same indicator has a standard brick wall with a thickness of more than 50 cm is only 0.405.
Another important difference between the foam from other insulation is that it does not hold, but reflects heat. Due to the low thickness, it can be used to insulate any premises, as an independent heat insulator or paired with other thermal insulation materials.
The value of the marking of the foil insulation
Insulation, Penofol is a few species. Each type of thermal insulator has its own unique labeling:
- 1. A. Standard foam, having a foil coating on one side. Most often used with inner warming together with other heat insulators, for example, with foam or expanded polystyrene.
- 2. B. Material, aluminum foil coatings on both sides. It can be used as the only one.
- 3. C. Self-adhesive insulation, on the one hand there is a foil layer, and on the other - foamed polyethylene coated with moisture-resistant glue. Different simplicity of installation.
- 4. ALP. Laminated foam, the foil side of which is protected by a polyethylene film. Most often applied in agriculture.
- 5. M and R. Relief insulating material with one foil layer.
- 6. Super Net. The heat insulator, which is used to isolation of engineering systems and communications - heat supply, pipelines, air ducts.
- 7. Air. It is used for insulation of air ducts.
For adverse climatic conditions, it has a thickness of up to 4 cm
The market also contains a foam, which is suitable for use in the most adverse climatic conditions. It is distinguished by increased thermal insulation characteristics and has a thickness of up to 4 cm. There are insulation with marking "2000", these are the most affordable materials that differ from standard heaters with reduced strength and less functionality.
Characteristics of the insulator - what makes it popular?
Foil foam is considered universal insulating material, the advantages of which are provided by its excellent technical characteristics. It can be used for thermal insulation of various building structures in residential and non-residential premises, inside and outside buildings. The most important parameters of heat-insulator include its following properties:
- 1. Thickness. One of the most important advantages of foam is its small thickness, which is much less than that of other insulation. The standard thickness of such thermal insulation does not exceed 10 mm. The thickness of the foam directly affects its cost. For internal insulation, it is best to use a thickness of 5-6 mm thick.
- 2. Heat conductivity. The thermal conductivity of the combined insulating material is very difficult to calculate, therefore, it is usually called the resistance of its heat transfer for the foam. For folgied on two sides of the material with a thickness of about 5 mm, this indicator is 1.23 m 2 / s / watt. To ensure the same heat transfer resistance using mineral wool, the installation of a heater with a thickness of about 80 mm will be installed.
- 3. Moisture resistance. The material does not absorb moisture, its moisture absorption is from 0.35 to 0.7% on m 3.
- 4. Sound insulation. The correct installation of foaming provides high-quality noise insulation of the premises - up to 32 decibels. To increase the level of sound insulation before installing the insulation, it is necessary to extract the seams of building structures.
- 5. Parputness. The vapor permeability coefficient of the foam is 0.001 mg / m / h / pa. Thus, this insulation can be mounted without the pre-installation of the vapor insulating layer.
The popularity of the thermal insulator is determined not only by its technical characteristics, but also resistance to various external influences. This material can be used at temperatures from -60 to +100 o C, withstands the impact of almost any chemicals, is distinguished by environmental safety for humans. Manufacturers assure that the foam may serve for 200 years, but it is impossible to test the reality of such applications, since the material is widely applied relatively recently.
Can be mounted without pre-installing a vapor insulating layer
The insulation is difficult to flammable material, does not support burning. It fireproof, therefore it can be used in different buildings and rooms. When combustion, water and carbon dioxide highlights, if there is no oxygen in the surrounding space, carbon monoxide can be released. However, it is characterized by average rigidity, bending strength and compression ranges from 44 to 74 kg / m 3. Thanks to these technical characteristics, the foam today is used almost everywhere. It perfectly protects rooms from low temperatures, from cold bridges and provides a reduction in the load on the heat supply system installed in the rooms.
Advantages and disadvantages - what you need to know in advance?
Analyzing the technical characteristics and properties of foam, its positive qualities include a small thickness and low weight. It is thinner and easier to almost all known analogues and at the same time provides very good protection for insulated rooms. Due to the simplicity of installation, the material can be installed on their own at home, not referring to the help of professional professionals, the services of which are quite expensive. The material is easy to cut with scissors and mounted on the construction bilateral scotch. Even more simplifies the installation of the fact that the installation does not require an additional hydro and vapor barrier.
The foam consists of foil and polyethylene agent, which are completely harmless to humans, because it is considered completely safe and environmentally friendly. Even with emergency situations and fires, the material withstands very strong negative impacts and can be used in buildings with high fire safety requirements. In addition, it is distinguished by the available price and is one of the best, if not the best insulation in terms of price and quality ratio.
But it is not necessary to think that the foam has no shortcomings, negative features are completely in all construction and facing materials, and these features need to be taken into account to carry out insulation as high quality as possible, ensure the most favorable living conditions in the inner premises. First, the material is distinguished by low rigidity and is not able to withstand substantial physical exertion, it cannot be placed, painted and bold, the only option of the external finish is the installation of drywall on the crate, on top of which any facing events are already allowed.
Secondly, to ensure high-quality consolidation of material on the surface, it is necessary to use high-quality special glue or construction tape. Thirdly, the foil layer performs the electric current well, because when installing the insulation, it is necessary to protect it with a quality of contact with wiring.
Prices and manufacturers - trust, but check
To warm up the premises of the house or apartment qualitatively, it is necessary to competently select the most suitable type of foam. Most often for household use, experts recommend materials with a thickness of no more than 5 mm. They provide high-quality insulation and cost inexpensively. Penofol is suitable for designing any residential premises and wet areas in buildings, but its use for the insulation of the sauna, the bath is not recommended. In such conditions, it is better to use thermal insulation materials based on penpropian.
It is necessary to determine the required amount of thermal insulator in advance in order not to overpay for unnecessary materials. To purchase, you should calculate the exact area of \u200b\u200binsulated surfaces, and after that, the number of rolls of polystroplate. Rolls may contain different volume of the insulation, one roll can be enough to cover from 9 to 18 m 2 of the wall area. Most of the rolled insulation from foams are made using aluminum foils, but such materials can not be used due to high electrical conductivity. Heat insulators, a folgized layer of which is made of lavsan metal film, are less thermal conductivity, but they are somewhat more expensive.
Always check the quality of the foam before buying. To do this, expand the roll and look through the material on the bright light. The insulation of the insulation must be homogeneous, without spots and strips.
Penofol is a registered trademark, in our country it is made by only one Lit plant. You can find on the market and analogues of such a thermal material implemented under other names:
- Tepopol;
- Parlelex;
- ENERGOFLEX;
- Isolon;
- Magnoflex and others.
The price of the insulation directly depends on its type, brand and thickness. The cheapest Penofol-2000, its value begins with 50 p per 1 m 2, and the lowest quality insulation of this type. The insulation of the brand A is a classic material, the cost of which is not lower than 160 p for 1 m 2, the foofol-B is from 180 p per 1 m 2, and the self-insulator's self-insulator is not less than 230 p per 1 m 2.
Learn the packaging of thermal insulation before purchasing it, as well as all accompanying documents. If the manufacturer is not specified, or this is not the only plant in Russia, producing a foam, then you are dealing with analog material, which can be very reflected in the quality of the original.
The foofol foil, produced at the "JSC Plant Lit", has long won the trust of most builders. It has excellent performance and almost perfectly falls on any type of surfaces. In addition, an affordable put it on the first place of the rating of insulating products.
Foofed Penofol - Description, Characteristics
Foofed foam is a material of several components. The basis of this insulating material is foamed polyethylene. From above of the polyethylene film, an aluminum foil is applied, which reflects heat inside the room.
But not always the foil foofol is covered with aluminum foil on both sides, and its thickness ranges from 10 to 35 microns e. The insulation has a closed structure. The thickness of the foamed polyethylene varies from 3 to 10 mm. It is primarily depends on the type of material itself.
Even with such a slight thickness, the insulation of the foam is surprised by the excellent parameters on para- and heat insulation, a high degree of flexibility. And moreover, the layer is absolutely safe for the environment and for humans, since it does not contain toxic substances.
Varieties of foam
The following models of this insulating material are used in construction:
1) Type A - has only one-sided coating. If when installing into the wall, it is used in combination with other insulation, then you can get the maximum effect.
2) Type B is a bilateral coating material. It can be used without any other insulation.
3) Type C - one side is coated with foil, another sticky layer of contact glue.
4) ALP - only one side of this type is covered with laminated polyethylene film, and the second foil.
5) Types R, M.
Technical properties of foil foam
Penofol is a heatel that has the properties of heat reflection. These properties are achieved due to the coating of the foil, which interacts perfectly with infrared rays. Fungalized bilateral foam foam has low thermal conductivity, since its base contains gaspen polyethylene, the pores of which inside are tightly closed. If you use a one-sided layer in the roof of your home or when installing into the wall, you will notice how heat loss has decreased, which were before installing the insulation.
Penofol One-sided is often used on construction sites both industrial facilities and ordinary apartments, since it has a high flammability ratio. This property is achieved by applying foil to the external parties. If a fire happens, for example, at a plastic production plant, the temperature will be too high, and the foil can burn, since its thickness is insignificant. After combustion, the foil begins to burn the base - polyethylene. Fire characteristics according to GOST - G1.
The insulation perfectly copes with large temperature differences and high humidity counseling its excellent thermal characteristics.
Basic Rules for Mounting Fenofole
Foofol folgized unpretentious to the surfaces to which it is placed. This insulation is mounted on any surface, and besides, it does not require any surface preparation. No processing should not be carried out and immediately produce insulation.
One of the main requirements when laying a foil foam is a small distance between two and more elements. The distance between them should not exceed 2 cm, as if you take more, it can negatively affect its qualities. For example, moisture formation may occur when wall insulation.
The installation of foam does not require large labor. When the walls are insulated, the surface that is covered with foil should be laid only inside. Using a construction stapler, mounting glue or double-sided adhesion glue joints and fix the foil foam. When installing foam on an adhesive basis, you do not have to use additional tools. As a rule, such sheets are attached to jack, which facilitates installation. Seam, which is formed from the joints of two sheets of the insulation, it is necessary to make a special tape lacc, which is based on aluminum.
Do not forget that aluminum is well conducted by electric current. To further avoid problems with electricity when laying insulation, take care of the insulation of electrical wires in advance. If the wires pass through the sheets of self-adhesive foam, they need to be isolated so that they do not touch aluminum. If you ignore the insulation of the wires, then in the future, even a small debris of electrical wires can lead to a serious fire.
This article is devoted to the Penofolu - one of the most effective materials for reflective thermal insulation, among the insulation presented in the market.
1 Features and Scope of Application
Penofol is a two-layer heat-butter material consisting of one or two foil layers applied to the base of foamed polyethylene.
Depending on the type of product, the density, as well as the thickness of the polyethylene foam, may differ. As a rule, the standard thickness of the insulation is from 2 to 10 millimeters. There are also products with a thickness of 40 mm, however, they are weakly distributed due to small demand.
- Thermal insulation of the inner surfaces of walls and facades in a brick and wooden house, mansard, veranda and attic;
- Heat-, moisture, steam-insulation saunas and baths;
- Arrangement of reflective thermal insulation in warm floor systems;
- Thermal insulation of pipeline mains;
- Thermal insulation of ventilation systems, air conditioners and sewage pipes;
- Screening material for heating radiators.
2 types of foam and their specifications
There are three main types of foams, which differ between themselves as structural features and technical characteristics:
- Penofol type A;
- Penofol type B;
- Penofol type with similar to.
Type A is a foam with one-sided foil. This is the most popular version of foam for complex thermal insulation using additional insulation.
Type B is a foofol having foil from two sides. This material can be used as the main thermal insulation for the walls, ceiling, floors, attic ceiling of residential and industrial buildings, as well as for thermal insulation baths, saunas, pipeline highways and industrial equipment.
Type C is a foam type with foil on one side and adhesive coating on the other. Such a coating makes it possible to mount the foam without applying any additional tools and materials.
Consider the technical characteristics of the most sought-after types of foam.
- The temperature range in all three types of insulation is from -60 to +100 degrees as y;
- The coefficient of thermal shielding of the foil layer in all species within 95-97;
- The thermal conductivity coefficient of the material, W / MK: Type A - 0.037-0.049; Type B - 0.038-0.051; Type C - 0.038 - 0.051;
- Screwing moisture with full immersion for 24 hours: type A - 0.7%, type B - 0.6, type C - 0.35;
- Specific weight, kg / m3 (± 10 kg): type A - 44, type b - 54, type C - 74;
- The modulus of elasticity under load in 2 kPa, MPa: type A - 0.27; Type B - 0.39; Type C - 0.26;
- Compression index at 2 kPa: type A - 0.09; Type B - 0.03, type C - 0.09 as y;
- The vapor permeability of all types of foam does not exceed 0.001 mg / MCHP;
- The specific heat capacity of the material in all kinds - 1.95 J / kg;
- The tensile strength of all types of foam is 0.035 MPa.
There are also less common types of foams.
Penofol Type R - material according to the technical characteristics is similar to the Penofol type A, however, foil has a similar type, which is better suited for creating multi-layer insulation. The thickness of the foil in the foofole type R is 14 microns, the heat transfer coefficient is 0.04 W / MK.
Penofol Type ALP is a widespread option in agriculture, where it is used as reflective thermal insulation for greenhouses, incubators and peasants. A feature of this type of foam is one-sided lamination from a polyethylene film.
Penofol Type NET is an option intended for thermal insulation of ventilation channels, pipelines and heat mains. The manufacturer indicates that NET foam properties are similar to type B characteristics, it distinguishes its only large elasticity.
2.1 Disadvantages of foil foam
Let's start with the disadvantages that, in foil foam, significantly less than advantages. To be accurate, then significant minuses that limit the use of foams as thermal insulation material are all three.
- Low density like.
Due to the lack of stiffness, the foam cannot be used as a coating under the plaster, or by overlooking wallpaper. The foam is a very soft material that cannot hold them normally.
Penofol, in the case of use as the main heat insulating layer, is trimmed with a facing layer for which a special carrier frame is placed.
- Loss of thermal insulation characteristics during mechanical damage.
When insulating with foam, it is very important to monitor the integrity of the material, since even the slightest damage significantly reduce the shielding abilities of foil foam.
In this regard, when installing the foam, it is not necessary to resort to the use of nails or screws. The manufacturer recommends mounting foam to surfaces using a special adhesive composition. Reviews indicate that the glue fixes the foam on the walls is quite efficient.
- Insufficient thermal insulation properties for use as the main insulation.
One of the key advantages of the foam is the minimum thickness - the material does not eat free space, but it is quite obvious that the thickness of the base of 0.5-20 mm is not capable of ensuring insulation similar to the effectiveness of insulation 10 centimeters of mineral wool.
However, with the main functional purpose - reflective thermal insulation, the foil foam copbles very effectively.
2.2 Advantages of foam
The following characteristics are considered the traditional strong sides of the foil foam foam:
- Parosolation properties and hydrophobicity of the material - the foofol is not afraid of condensate, it does not absorb moisture and is not exposed to accelerated destruction at a constant stay in the humid air, which allows the use of a foam for thermal insulation by bath and saunas;
- The thickness of the foam - the thickness of the material is effective in thermal insulation characteristics, as a rule, is about 1 centimeter. This thickness gives an effect similar to thermal insulation with 8 cm. Mineral wool, or 4 cm. Extruded polystyrene foam;
- Ecology and safety for health - materials from which produce foofol - foil and polyethylene are widely used in the food industry as packages for products. Penofol himself is certified according to all European and Russia's sanitary and environmental standards;
- Noise insulating properties - the structure of foamed polyethylene has the ability to effectively suppress both noise propagating air and shock noise;
- The simplicity of transportation and ease of installation is the minimum thickness of the insulation makes it possible to wind it into a compact roll, which without problems is transported by any vehicle. When installing the foam, there is no need to use special tools - the material is perfectly cut by conventional scissors;
- Fireproof - in the class of flammability The foil foofol refers to the class G2 (the difficult-scale materials prone to self-filing).
Despite the fact that the penofol is primarily the heat-insulating material and is used to reduce heat loss during the construction and repair of various premises, the material is often used as a vapor insulating layer. Foil Penophol does not pass moisture through itself and can be used as a waterproofing layer when the mineral wool is insulation of various structures. Consider in the article more. The pros and cons of the foam and its characteristics.
Today, the number of thermal insulation materials offered by producers is so large that not everyone heard of some of them. Such a material as a foam is known to many, as it has good thermal insulation properties and characteristics. Foil foam due to its properties will save from extraneous noise and absorb moisture, and will also significantly reduce the heat exchange in the room.
The insulation consists of several layers - there is self-fighting foamed polyethylene between the aluminum foil layers. Thickness is up to 30 microns, and the share of the substance is about 99.4%, as a result, it turns out a small thickness and weight organic insulation, which does not contain harmful additives. The foofol works on the principle of thermos - reflects thermal radiation, practically without absorbing it.
The term "Penophol" means not a heater, but a brand. The reflection of heat by foam occurs on the principle of thermos. There are a number of materials that reflect thermal energy - precious metals (platinum, silver, gold) and well polished aluminum. The rays of thermal energy reaching the surface of the material are recorded by 99% in the direction of the warm room.
Developers are gradually moving to reflective thermal insulating materials, as they are beneficial. Gradually, such insulation when waterproofing ceilings in the bath and in other rooms will take a leading position. Today there are many materials under the brand name of Penofol, we will list the most popular brands. Among them, it is possible to distinguish a foam type "A", covered with foil on one side.
Characteristics of foil foam
Foam foam on one side - type "A"
Foofol foil from two sides - type "b"
Foilled self-adhesive fenophol - type "C"
The "C" type foam refers to self-adhesive materials - on the layer of polyethylene is applied on one side a polished aluminum coating, and on the other hand, a layer of moisture-resistant glue. It is used where it is difficult to make the attachment of ordinary foam, for example, from inside. Penofol combines the reflection and absorption of thermal energy, which reduces the heat loss in the winter house.
Penophol thickness. The thicker material, the more expensive the insulation. The amount of foil layers is directly affected by the amount of foil layers to the value and on the main technical characteristics of the foil foam. Standard thickness of foil foam: 10, 8, 5, 4 and 3 millimeters. Rolled insulation thickness of 10 mm thick with a double layer of foil is the most expensive, but it will preserve the warmth.
Conducting heat. Since the insulation combines the reflection of heat and its absorption, it is difficult to compare the characteristics of the foam with the minorvata or the characteristics of the foam. If you take a material with a thickness of up to 5 millimeters, coated with aluminum foil on both sides, then we obtain resistance to 1.23 square meters-degree Celsius per watt, which corresponds to a layer at least 10 cm.
Parry permeability and sound absorption. Penofol almost does not absorb moisture, is an excellent obameral barrier, which is favorably distinguished by the insulation from most modern materials. The Penophol Parry Permeability Coefficient is less than 0.001 mg per meter-hour-paskal. Penofol allows you to protect the room from the noise from the street.
Service life and safety. Material refers to standards to substances that do not support burning. When sunbathing, water and carbon dioxide are released from polyethylene. Polyeneetylene is environmentally friendly and serves to 200 years, foil layer can save from the effect of electromagnetic radiation, reducing them twice.
Table. Technical characteristics of foam
Application of foam in construction
Based on the above, the insulation of Penophol. Specifications have universal, it can be used for inexpensive thermal insulation of country houses and for insulation of high-rise buildings. Offices, residential and industrial premises, wage from inside can be quickly wasolate with this material. Roll material, ventilation in apartments and heating pipes in homes.
Foil Penophol will help keep warm in winter in the house, and in the summer it blocks the way summer heat. But, like other thermal insulation materials, the Penophol does not do without its drawbacks, consider at the end of the article more, in which they conclude, because the minuses of the material should also be considered.
Advantages and disadvantages of foam
- Polyethylene foamed as the basis for finishing does not have sufficient rigidity, on top of it to be plastering or use the material under the pasting fabrication is impossible. From a strong pressure, thermal insulation is compressed and bent, later the deformation may not recover.
- Fastening a roll material may be difficult, you will have to buy additionally adhesive compositions. Use for fastening of foaming brackets is not always appropriate, because The heat-insulating and vapor barrier characteristics of the heat insulating layer will be significantly deteriorated.
- Applied
Penofol - insulation is determined as heat-noise-insulating material. It is performed from environmentally friendly substances, and has a small thickness and low weight.
In industrial and civil construction used for:
- insulation basements;
- wall insulation;
- insulation of the attic;
- ceiling insulation;
- insulation roofing;
- floor insulation;
- hydraulic insulation of pipes;
- thermal insulation of the air conditioner;
- hydraulic insulation of outer walls;
- enhancement of waterproofing and massive isolation;
- protection against dust;
- repair ceiling coating;
- strengthening walls;
- insulation doors;
- isolation of water heating elements.
In the automotive industry, the foam is used as a material for sound insulation and insulation of the transport cabin.
Specifications
Classification of material
The following types of foil foam insulation are produced:
- Type A - material based on polyethylene foam with foiling one side;
- Type B - material based on polyethylene foam with foils of both sides;
- Type C (self-adhesive) - material based on polyethylene foam with foils of one side. Refers to self-adhesive insulation, due to the fact that a layer of glue is applied to the other side, which is protected by adhesion coating.
There are also varieties of foam.
Depending on the additional coating, shared:
A, B, C-LL - with lamination by polyethylene terephthalate film;
A, B, C-LP - with lamination by polyethylene film;
A, B, C-M - embossed with the foil of one side;
A, b, c-r - embossed with foil one side;
Perforated
Recently, the release of foam with perforation, i.e. The ability to output moisture from the material. This type of insulation is used mainly on the outer facades of the building. The walls, where the insulation was used by foam, acquire the ability to "breathe".
Penofol is made of polyethylene foam on which an aluminum foil is fixed by pressing with one or both sides. It is permissible to use polyethylene agent of several brands, and not just the PPE, in the absence of deterioration in the quality and properties of the insulation. The adhesive layer should be protected by adhesive material.
The thickness and length of the insulation
The cost of the insulation directly depends on its thickness. What she is more, the price is higher. Also, the cost increases on the number of foils and coating layers.
It is manufactured with thickness: 3mm, 4mm, 5mm, 6mm, 8mm, 10mm (on demand in rare cases is performed with a thickness of up to 40mm). The foam of 1 centimeter thick has the highest noise protection rates and is best kept warm. In the first place in popularity remains a thickness of 5 mm thick, due to the optimal ratio of quality and price.
Released in rolls. The length of the standard roll (depends on the thickness): 5m, 10m, 15m, 30m, 50m.
The density of the insulation
The proportion of the insulation depends on the thickness and is in the range of 38 - 84 kg / m3. Given that the insulation has low density, the use of it is difficult for further loads. When applying a small load, it will be pressing inside.
The ability of the insistance to absorb water
The ability of any product to absorb and retain moisture is called water absorption. With a high indicator of this value, the value of thermal conductivity increases, the specific gravity is increased and the strength of the material is significantly reduced.
The water absorption in the foam depends on its type:
Type S. — 3,5 %;
Type B. — 0,6 %;
Type A. — 0,7 %.
Under vapor permeability, the ability to skip and delay pairs, therefore, with a large coefficient of this value, the thermal conductivity indicator is also higher. When using foam, there is no need to lay an additional film.
For comparison, the vapor permeability of various building materials:
- plywood - 0.02 mg / (m * h * pa),
- foamflast - 0.023 mg / (m * h * pa),
- concrete - 0.03 mg / (m * h * pa),
- Chipboard - 0.12 mg / (m * h * pa).
- At Penopol Parry permeability is less than 0.001 mg / (m * h * pa).
Penophol ability to carry out heat
The thickness of the aluminum foil used to coat the layer of foam polyethylene, from 12 to 30 microns. Percentage of pure substance more than 99%.
In time of the studies of the Dewar, it was established that a number of materials could almost completely reflect thermal energy, however, due to this, the material is able to warm up and becomes necessary for the design of the structure with a thermal obstacle. The foam function performs foamed polyethylene.
The level of thermal reflection of the polished foil is at least 97%.
Important! Resistance depends on the thickness and type of insulation. For type in with double foil and 4mm thick, this indicator is 1.20 m2 * C / W; 5 mm thick - 1.23 m2 * C / W, a thickness of 10 mm - 1.355 m2 * C / W. For comparison, the mineral wool layer for such resistance should be more than 85mm. Data calculation was adopted in accordance with SNiP.
Soundproofing
The unique feature of the foam is its ability to sound insulation with a small thickness of the insulation. This property is actively used in the automotive industry and, if desired, can reduce the noise from foreign factors at home.
Given that this material can be used both indoors and outside, and with a thickness of only 4-5 mm, it turns out to significantly reduce the noise of the apartment, this is undoubtedly the useful quality of the insulation.
Penophol has a sound absorption above 32 dB.
Explosion hazard and toxicity
Temperature borders of use from +100 to -60 degrees Celsius. At such temperatures, the foam is absolutely ecological material and completely non-toxic. When using it in a room or street conditions, the use of precautions are not required.
The sticky glue composition used in the manufacture of the insulation of type C, not toxic. Based on water acrylic dispersion used glue. The emulsion used is not explosive and not toxic. Hazard class - 4 (low hazard substances).
The material applied to the adhesive basis for its protection is a lavsan silicon film. Not toxic.
Fire safety foam
This material belongs to substances difficult to burning. Penopol has an appropriate certificate that it is not flashed.
With burning foam:
- melted upon contact with open flame;
- not flashes;
- does not burn.
Important! By combustion, the foofol refers to the group G1 (material weakly fuel, burning does not support, the flame does not distribute).
On flammability refers to the group B1 (it is not ignited, it is capable of withstanding the heat flow more than 500ºС).
By the ability to form smoke belongs to the group d2 (moderate ability of smoke formation).
Lifetime
Since Penopolietale is used in the manufacture of foam polyethylene, which is a durable material, and the term of operation is about 200 years, the insulator is durable. However, it is worth it in mind that aluminum used for the coating is capable of oxidizing from time to time. In addition, due to the materials used in production, it is possible to reduce the effects of electromagnetic emissions up to 10 times.
Methods Applying foam
Use on the floor
If we need heat insulation of the floor, the installation of the foam is carried out on top of the lag, the foil side facing up, without break. Basically, a sufficient type is a thickness of 4 or 3 mm. It is necessary to ensure the air layer in 20 mm. All over the junction to carry out sealing insulation using an aluminum adhesive tape.
When laying a foam on a concrete basis, it should be taken into account that concrete is an aggressive medium, therefore, using a foam, the floor is covered with a polyethylene film or an insulation coated with a protective film is used. The laying is made by the foil side up, the jack of jack. Sealing is performed using assembly tape. The heating system is stacked on top and poured with a screed. On top lay decorative sexual coating: laminate, parquet, tile.
Preservation of heat from heating devices
To increase the temperature in the room, it is reasonable to establish a penofol type C or A on the wall behind the battery. In practice, the effectiveness is proved to increase the heat transfer from the battery by 20%. Using a 5-3 mm thick insulation, you can increase the temperature in the room for 4 degrees.
Wall insulation
If in the winter time in the room raw and the temperature drops below 20 ° C isolation of walls. It is possible insulation outside and inside the house. The effectiveness of insulation indoors is significantly higher. The use of type A isolation is substantiated, in a thickness of 5 mm.
Application type S.
In places where it is difficult to use a type A foam and B type C. It is actively used in insulation of water heating boilers, insulation of air ducts, thermal insulation by pipeline, which also eliminates the appearance of condensate.
Glue used for foam
The use of glue for fastening the insulation has several advantages:
- small time and price costs;
- does not require special skills;
- low in technological plane;
- no need to use a professional tool.
But, the carrying capacity of the attachment with the help of glue is not high and depends on the weight of the material. The advantage of the foam is the weight. He is light. The gluing depends on the adhesive properties of the adhesive basis, i.e. The ability to penetrate the surfaces for gluing.
The glue, which includes a solvent on an organic basis, has the highest efficiency. An important indicator for the strength of the mount is water resistance.
Glue used in residential premises should not be toxic. Adhesive safety can be guaranteed with the presence of an EMICODE certificate. To increase the efficiency of the glue, it is necessary to clean the surface from pollution, dust, coatings and eliminate all irregularities, cracks. When using a bonding agent, you must clearly follow the instructions. Then, the foam will stay for a long time and glued well.
Using the fastening method using glue is inferior to other more common and reliable installation options:
- fastening with lag;
- fixing brackets;
- raiki mount;
- fastening for screws and others.
It is also important to remember that regardless of the fastening method, it is necessary to qualitatively isolate all the joints of the design of the foam, and it is worth preferring the method of laying the "jack into the joint" in front of the "Vansel" method. It is best to use special metallized construction tape as insulation.
When insulating the bath, saunas and other rooms with high humidity, it is better to give preference to other methods of fastening.
Analogs of foam
It is important to understand that the foam is not the name of the insulation, but a certain brand. Therefore, there are a number of analog materials with similar properties.
Among the analogs can be allocated as follows:
- Aluhform
Insulation, performed from foamed polyethylene covered with a metallized film or polished by aluminum foil. Application areas are identical with foam. - Isofol.
Material for insulation consisting of one, two layers of polished aluminum foil or aluminum spraying on a lavasan film, covering foam polyethylene. Produced in the form of rolls. Used as heat-insulation. It is used in the construction of industrial and civil matters buildings. - Slap: Stipol F2, stipol F2, stipol lm;
Foamed polyethylene with laminated metal-plated film (stipol lm) or one (stipol f) or two (stipol F2) by layers of polished aluminum foil. It is used as insulation for walls, floors, roofs, and other structures. - ENERGOFLEX.
Insulation, made of foamed polymer or polyethylene. Produced in the form of tubes, plates, rolls. Widely used in heating, air conditioning systems and in enclosing structures. Roll reflection coefficient is 90%.
