    Tulppa® - Technical specifications

    The core of the Tulppa® panels is made from Finnfoam, i.e. extruded polystyrene, which is a waterproof and mold-proof material with a high thermal insulation capacity. No bromine compounds or other environmental toxins are used in the production of Finnfoam. Finnfoam and the Tulppa® panels carry the M1 emission rating for best quality of indoor air. The surface of the panel is covered with a sturdy, special-purpose cement mortar reinforced with a fiberglass mesh. The panels can be attached to all foundations.tulppa-levy-02.jpg
