Styropan XPS extruded polystyrene is a foamed, composite material, widely known worldwide with many building construction uses. It is a “closed cell structure” material, which, through polymerization process and continuous extrusion takes the form of thermal insulation panels.
The properties that differentiate Styropan XPS extruded polystyrene from the rest of the insulation materials are:
- Very high mechanical resistances (compression strength up to 10% of distortion, vertical tensile strength at the facades, shear strength) thus high load-bearing capacity which is particularly important in terraces, building floors, industrial facilities floors etc.
- Very low water absorption that make it an ideal insulating material in various applications such as in underground level circumferences, inverted or planted terraces etc.
- Very low values of thermal conductivity coefficient, that ensure minimal heat flow between the building shell and the environment, achieving thermal comfort with the least possible energy consumption.
- They are 100% recyclable and they do not contain chlorofluorocarbon (CFC), hydro-chlorofluorocarbon (HCFC) or hydro-fluorocarbon (HFC).
- They exhibit excellent grip to concrete or to adhesive mortars as they can be manufactured by removing the extrusion surface and/or in the form of textured, rhomboidal surface (e.g. Styropan XPS ETICS EMB).
XPS products are applied to a building from its foundations to its roof, indicative application fields:
- Roofs (coating of storeys – pilotis spaces, concrete panels, conventional & inverted roof)
- Floors (residences and underground levels)
- Walls (double stretcher bonds, complex exterior heat insulation/ETICS systems, wall dividers, insulating concrete forms/ICF)
- Inclined rooftops (internally or externally)
- Underground levels (around the circumference of the wall dividers internally or externally, floors, foundations)
