Extruded Polystyrene Thermal Insulation

Foamular 250 extruded polystyrene xps provides continuous insulation in insulated concrete sandwich panel walls in masonry unit cavity walls or when used with non penetrating surface mounted furring systems over masonry or concrete walls.

Extruded polystyrene thermal insulation.

Extruded polystyrene material is also used in crafts and model building in particular architectural models. A superlative and perfect system of 100mm thick insulation blubber below skin a dense underfur and 150 mm long guard hairs over it s body enables them to face even the severest of weather conditions. Expanded polystyrene and extruded polystyrene are both made from polystyrene but eps is composed of small plastic beads that are fused together and xps begins as a molten material that is pressed out of a form into sheets. Because of the.

The density range is about 28 45 kg m 3. In general thermal insulation is primarily based on the very low thermal conductivity of gases. Typical thermal conductivity values for extruded polystyrene are between 0 025 and 0 040w m k.

Foamular 250 retards the transmission of water vapor and moisture in masonry walls. In general thermal insulation is primarily based on the very low thermal conductivity of gases. Thermal performance is rated at r6 6 5 per inch but don t count on that if your winters are cold for the reasons we re about to explain. Pir polyiso or iso is a thermoset plastic product typically produced as a foam and used as rigid thermal insulation panel most often with aluminum foil facing.

It s therefore preferred in areas with rather extreme weather conditions. Polystyrene foams are good thermal insulators and are therefore often used as building insulation materials such as in insulating concrete forms and structural insulated panel building systems. Extruded polystyrene xps extruded polystyrene foam xps consists of closed cells. The advantages of extruded polystyrene xps has good thermal conductivity generally higher than eps.

It s also highly resistant to different temperatures. It offers improved surface roughness higher stiffness and reduced thermal conductivity. Typical thermal conductivity values for extruded polystyrene are between 0 025 and 0 040w m k. Polystyrene foams are 95 98 air.
