Extruded polystyrene thermal insulation.

Xroof roof insulation boards are ideal for a multitude of roofing requirements inc. In general thermal insulation is primarily based on the very low thermal conductivity of gases. It offers improved surface roughness higher stiffness and reduced thermal conductivity. Extruded polystyrene xps extruded polystyrene foam xps consists of closed cells.

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. Because of the. Foamular 250 retards the transmission of water vapor and moisture in masonry walls. 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. 50mm cellecta hexatherm xroof 300l is an extruded polystyrene thermal insulation board designed specically for inverted roof applications where a high resistance to compression and water absorption is essential. The advantages of extruded polystyrene xps has good thermal conductivity generally higher than eps. 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.

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. Extruded polystyrene material is also used in crafts and model building in particular architectural models. Heat cold and water are usually unsuccessful at overcoming quality extruded polystyrene. It s also highly resistant to different temperatures.

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. 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. Polystyrene foams are 95 98 air. Typical thermal conductivity values for extruded polystyrene are between 0 025 and 0 040w m k.
