Floor underlays are made from XPS extruded polystyrene using a thermoforming process. They are also reinforced with PET film.
They are designed for use in residential or public buildings, excluding wet rooms. The underlays can be used under wooden floors, wood-based flooring, hard floor derivatives and carpets.
Thickness: 3mm / +/- 0.25%
Length: 12m / +/- 1%
Width: 1m / +/- 1%
Density: 28 kg/m3 / +/-20%
Thermal resistance: 0.11 m2K/W / +/-10%
Thermal transmission coefficient: 0.029 – 0.034 W/(mK)
Compensation for unevenness: 2.9 mm
Compressive strength: ≥ 75 kPa
Permanent static load: ≥ 3 kPa
Dynamic load: › 100,000 cycles
Resistance to falling objects: ≥ 125 cm / +/-5%
Impact sound in rooms below: 18 dB / +/-5%
Room sound insulation: 9% / +/-5%
Insulation should be laid with the underlay with silver insulation on the floor and polystyrene on the surface.
Not suitable for underfloor heating.
