Extruded Foam Polystyrene (xps)
XPS belongs to styrofoam insulation materials but it is manufactured using different technology as the
expanded polystyrene (
EPS). By the XPS manufacturing, the polystyrene is extruded (under pressure) to the spevial tunnel (extrudor).
XPS vs EPS difference
Which leads us to the most important difference between these two insulation styrofoams and it is that the extruded
polystyrene insulation (XPS) cellular structure is closed. Therefor the XPS doesnīt absorb water, itīs capilarity is very low and also itīs thermal conductivity is much lower than of EPS. Based on the above properties of
extruded polystyrene, it is mostly used when constructing the roofs with the reverse order of insulation layers.
Advantages of extruded polystyrene foam
- has no impact on peopleīs health; - extruded polystyrene insulation installation is very easy; - can be molded or any other way shaped; - waterproof and resistant against all in water dissolvable stuff.
Disadvantages of extruded polystyrene insulation
- the foam polystyrene insulation is not resistant against organic solvents and therefor cannot be used in combination with MPVC hydro-insulation foils. The XPS segments usually are covered on its face side with the 1 cm plast cemet layer that serves as the protection and stabilsation layer.
