In many sources, dedicated to the issues of construction and repair, foam PE is increasingly mentioned. And, mainly, in the context of finishing various surfaces. Polyethylene itself is known for a long time, but it is with "foamed" it is worthwhile to understand more.
Its other name is "foam polyethylene".It is already becoming clear that it is produced by foaming, hence has a porous structure. The peculiarity of the material is that all "cells" are isolated, or as they say, "closed".This in many ways determines its unique properties.
Features of foamed polyethylene
-
Low thermal conductivity. This makes it possible to use it for arranging layers of thermal insulation of buildings and structures. - Variety of assortment. Foam polyethylene can be "simple", foiled, reinforced( for example, fiberglass, used for greenhouses), to be part of other materials. With the introduction of various components into the initial composition, it is possible to give the final product the required characteristics( strength, frost resistance and a number of others).
- From the environmental point of view, the material is clean, as the use of freon by manufacturing technology is not provided.
- Good water repellent properties. Foamed polyethylene is well suited for the protection of surfaces subject to constant exposure to liquids.
- Simplicity of work with material.
- High sound insulating qualities.
- Polyethylene foam is capable of reducing the likelihood of ignition of other materials. For example, it is often used to protect wood.
- Some products can be operated in a temperature range of 240 ° C( -60 to + 180).
- Possibility of laminating almost any material( films, dolcane, paper and others).Due to this, it is applied everywhere.
- Durability, elasticity, wear resistance. It is not damaged by insects, rodents, mold or fungus.
- Low price for products, which makes it affordable for families with any income.
comparison of thermal insulation properties
Application
- For packing goods for various purposes, as a cushion layer. This is especially important to ensure the safety of transportation of goods. The material is available in thicknesses from 0.5 mm to 2 cm, which allows it to be used universally.
- As screens for reflecting heat. This property is used, for example, in the finishing of saunas( steam rooms), refrigerating chambers.
- At the defense enterprises. Such seemingly fragile material is, for example, an "integral part" of flak jackets.
- Well, the most common use is to reduce heat losses by various structures( thermal insulation): buildings and structures, pipelines and wells of engineering communications, reservoirs and caissons, ventilation ducts and technological mines.
By the way, products with one-sided foil are perfectly suited for attaching to the wall behind radiators, as this increases the heat transfer to the room( the efficiency of the devices increases by one third).But the foil on both sides - an excellent option for warming the roof. Reflect both the heat rising from inside the building, and the thermal energy of the sun's rays.
Given the diverse range of products, it is impossible to list all types of products. But the approximate prices for some of its varieties are appropriate.
With one- or two-sided foil
Sold in a roll version. The thickness of the material lies in the range from 2 to 10 mm.
The price is from 23 rubles per square meter.
Mats doubled
Thickness from 1.5 to 4 cm. Convenient for thermal insulation of flat surfaces on large areas. They are connected by a thermal method, which allows not to engage in further sealing of the joint.
The price is from 76 rubles / m2.
Penofol
For the arrangement of layers of heat and vapor insulation. In rolls, with perforations. There is a self-adhesive coating. The thickness of the material is from 3 to 10 mm, the length in a roll is from 15 to 30 m with a standard width of 60 cm.
Price - from 1 200 to 1 500 rubles / roll.
Wilaterm
Insulation sealing harness with a cross section of 6 mm. It is used in the temperature range from -60 to +80 0С.For sound and heat insulation of ventilation ducts, window and door openings( for example, in Swedish insulation technology), smoke removal systems and much more.
The price - from 3,12 rub / п.м.
