Today's summer is hotter than a year, staying indoors will be very sultry, at this time the heat insulation performance of the roof is very important. So the following small make up will take you to see a few more commonly used roof insulation materials!

The material of current housetop heat insulation has 3 kinds: it is porous material, heat reflection material and vacuum material respectively. Literally, the surface of a porous material has a lot of empty Spaces, and then you use the space in between to insulate it; The principle of thermal reflective material is to reflect the heat out before absorbing the heat, so the reflective performance of the material is better; Vacuum material is the interior of the material using vacuum barrier convection, so as to play the effect of heat insulation.

Common insulation materials are as follows:

1,rock wool board

Rock wool board is an inorganic fiber board, which has excellent thermal insulation, sound absorption and fire prevention performance, and belongs to a new building material. Because of its light weight and small thermal conductivity, it is widely used, but it is worth noting that the hygroscopicity of rock wool board is relatively large.

2, polystyrene board

It is mainly made of liquid foaming agent and polystyrene beads. It is often used as insulation material for building walls and roofs, ship refrigeration equipment and cold storage, among which, it is more common:

(1) extruded polystyrene board

Its thermal insulation performance is better, and moisture resistance, so the price is more expensive than other thermal insulation materials.

(2) expanded polystyrene board

Polystyrene plastic board has a good insulation performance, but its price is cheaper.

3, polyurethane rigid foam

The main raw materials are isocyanate and polyether, a new synthetic material with thermal insulation and waterproof functions. It is one of the materials with the lowest thermal conductivity in all thermal insulation materials at present, with good thermal insulation effect, good strength and good water resistance. The disadvantage is that the price is relatively expensive.

4, slurry insulation roof insulation material

Slurry insulation roof insulation materials, mainly with polystyrene particles, silicate and other raw materials, after processing and composite, has the characteristics of thermal insulation and has been widely used.

5, extruded board

Belongs to the foam molding material, has incomparable heat insulation performance, but also has the characteristics of high pressure, not water absorption and wear resistance, is widely used in the roof heat insulation system, belongs to the heat insulation material at a reasonable price.

The above is xiaobian for you to introduce rural self-built house roof insulation materials, I hope to be able to help friends who want to do roof insulation!
