Penofol - insulation of high quality at an affordable price. In addition to low thermal conductivity also has high Penofol sound insulating qualities and resistance to prolonged exposure to moisture. Often used during internal works, but some people use the material at the exterior of houses. Some penofol disadvantages listed at the end of the article.
Main article - insulation penofolom.
The main varieties of material
Material Penofol - thermal insulation coating with a thin film of aluminum. Available manufacturer in several varieties, each of which has certain specifications. Depending on the type of material price increases and its scope.
- "A" type. Most cheap variety of products, often used for insulation of technical premises. Aluminum foil located on one side only of the sheet.
- Type "B". It differs from type "A" so that the aluminum foil located on both sides of the sheet. The main layer is made of the same material as that of type 'B'.
- Type "C". As with the type "A" has Penofol active alumina layer only on one side, the second side coated with a special adhesive that simplifies installation of insulation.
- Perforated type. Available manufacturer recently used in outdoor applications. The material does not retain moisture, letting it out, at the same time increased its service life.
The above types of insulation are reasonably priced, and are popular because of high quality, durability and ease of use. Penofol products are light weight, making it easier to transport and installation. Arrive to the customer in the form of rolls in standard sizes.
Specifications penofol
The material has waterproofing properties and low thermal conductivity. Some types penofol example, articles "A" type highly specialized and suitable for rooms with an average room temperature.
The main technical characteristics of insulation Penofol:
- Thickness. The material thickness is directly proportional to the level of thermal conductivity. Penofol produced following thicknesses: 3, 4, 5, 8 and 10 mm. Most commonly used insulation whose thickness is 1 cm. Such material retains heat for a long time in the room and has a high sound insulation.
- Thermal conductivity. An important indicator for each heater. Base material - this two characteristics: the absorption and reflection of the heat flux. Aluminum surface reflects in reverse direction 90% more heat. Insulation thickness of 0.5 cm on thermal conductivity corresponds to the plate of mineral wool, whose thickness should be less than 1 cm.
- Resistance to prolonged exposure to moisture. Penofol not absorb liquid, regardless of internal or external mounting. For resistance to moisture does not affect the temperature conditions, day or time of year.
- Class of water vapor permeability. Is 0.001 mg / (m · h · Pa), which is quite low. Therefore, for the use of a heater optionally additional vapor barrier. Material well delay any level of fumes.
- Acoustic permeability. Penofol sound transmission is high, even the "A" class with one layer of aluminum, has acoustic permeability of 32 dB. Installing insulation on top of the material used (e.g., lining) only improve the sound insulation in the room.
- Combustibility. An important safety criterion of any category of heaters. When exposed to fire Penofol melts and is not illuminated, highlighting with carbon dioxide. Prolonged ignition may cause carbon monoxide weak consistency.
Penofol insulation meets all the specified service criteria. Permitted by its laying like under basic building material, and on top of it. Used in wood, brick, concrete and clay buildings.
Fields of application
Penofol - an environmentally friendly material that can be used in rooms of various types. It can be used for thermal insulation of buildings, having a technical function, as well as in the construction of multi-storey residential buildings. Due to the use of high-quality polyethylene foam, Penofol can be used in hospitals, orphanages, maternity institutions. The quality of the insulation is not affected by low temperature, can be penofol obkladyvat building without heating.
Penofol is not only used for insulation of buildings, it is mounted in a variety of construction and technical fields:
- In the cars. For example, in the engine compartment and the distances between cards and doors. Many garages Penofol used as an additional layer in the seat.
- As a shield layer between the building wall and battery heating system. Can significantly increase the heat transfer.
- As the insulating layer water pipe (hidden or open gaskets), sewer systems, Improvement reduced temperature conditions.
Advantages and disadvantages of the material
The main advantages of the material:
- Affordable price. Penofol cost much lower than the counterparts of other manufacturers. At the same time, the low price does not affect the quality of the material.
- Durability. At the heart of penofol only high-quality and natural ingredients, so the life of the heater is between 10 and 15 years.
- Select. A variety of products allows the buyer to choose a material with the desired qualities and his optimum price.
- Light weight, which directly affects the assembly and transport - only one person is required for laying the insulation. Overloading also does not take much time, since the heater is delivered to the buyer in the form of convenient rolls.
Insulation, in addition to the positive qualities, also has its drawbacks. The main of them - the careful handling during installation. Penofol fixed to the surface using a construction adhesive, prohibits the use of screws and dowels, which may spoil the sheet structure. Accordingly, additional costs for glue.
Secondly, the material does not have sufficient rigidity, however it can not be imposed on top of a layer of plaster or putties. Penofol has a soft structure, it is sufficient to press slightly onto the sheet surface, and it will sag, but restore shape after a short period of time.
Penofol belongs to the category of universal material the use of which is permitted in rooms with sudden temperature changes or no heating at all. Insulation has several varieties with specific technical characteristics. The packaging material is provided with a convenient and easy-to-understand instruction manual.
Insulation is durable and environmentally friendly, resistant to burning. It has the basic performance characteristics: a high insulation, low thermal conductivity, increased density, and light weight.
