- expandable polystyrene (EPS): used for thermo-insulation of facades, walls, ceilings
- extruded polystyrene (XPS): used to insulate undergrounds and bathrooms, thermal bridges, refrigerating rooms, flooring, reversed plane roofing
The thicker the polystyrene board, the higher the thermal resistance and lesser the heat lost.
Execution standard: ASTM A820-96 and DIN EN 10016
