Extruded polystyrene, also known as XPS or XSP, is a material made from crude oil mixed with a blowing gas, carbon dioxide gas or HFC gas for hydrofluorocarbons. It is offered in the form of a rigid panel of blue or yellow color. Extruded polystyrene has exceptional strength, able to withstand high loads and compression. This high strength is its highest quality, but not the only one. With the use of the Polystyrene cut sheets you can have the best deals now.

The undeniable qualities of extruded polystyrene

These polystyrene sheets are appreciated for their lightness but especially for their thermal efficiency, ideal for insulating buildings.

Extruded polystyrene, a featherweight with high resistance

The average weight of a polystyrene plate is 30kg / m 3 , a real featherweight that allows handling and easy realization, even with one man. This weight does not detract from its strength, however, since the extruded polystyrene is able to withstand the highest compressions up to 70T / m 2. Polystyrene is also resistant to wet conditions as this material does not fear water. Extruded polystyrene can be used to isolate:

floors and floors
roofs and roof terraces
interior or exterior walls.

Note: If expanded panels have an unfortunate tendency to crumble when cutting, extruded polystyrene allows all cuts without loss of material.

Insulation performance of extruded polystyrene

The thermal conductivity of the extruded polystyrene is generally between 0.029 and 0.037 W / mK. It is therefore one of the most efficient insulators. Extruded polystyrene makes it easy to reach the 25% energy saving, which entitles you to numerous support schemes such as the Tax Credit for Energy Transition or zero rate loans.

The defects of extruded polystyrene

Besides the advantages, polystyrene also has some disadvantages. Firstly, extruded polystyrene is not flame resistant , unlike other synthetic insulators such as glass wool or rockwool. If the thermal insulating powers are very high, the sound insulation of the XPS is very poor. As phonic insulators , there are better materials. The price can also play against it.
