  • Underlay including a moisture barrier for floating floors installed in commercial and residential areas. PolyFoam is recommended for use with all Junckers solid hardwood floors, where a moisture barrier membrane is required. PolyFoam is a resilient, step sound-absorbing 2 in 1 underlay mat for floating floors. It consists of a polythene membrane laminated to an extruded foam mat in such a way as to allow a 100 mm overlap of polythene on one side with built-in tape. PolyFoam is non-absorbent and must be laid foam-side down to prevent perforation of the membrane by sand or gravel particles.

    • Material: Extruded LDPE with a closed-cell structure
    • Weight: approx. 70 gram/m²
    • Thickness: 2.2 mm (Foam: 2.0 mm and Polythene: 0.2 mm)
    • Width: 1.1 m (Covers 1.0 m)
    • Roll size: 15m²
    • Colour: White
    • The temperature of application: -60°C to +80°C
    • Thermal conductivity: 0.05 W/mK (DIN 52612)
    • Water absorption: 0.5 % (ASTM C-272-53)
    • Age resistance: 50 years (SP 0414 and ISO 1798)
    • Diffusion density: 750 PAM
