Closed-cells virgin beads of expanded polystyrene for dry blowing into cavity walls and surrounding voids, with constant curve grain-size (Ø 3 - 6 mm), perfectly spherical, with controlled density, non-toxic, non-absorbent, rotproof, dust free, dimensionally stable over time, with no nutritional values for the growth of fungi and bacteria. The production is completely free of chlorofluorocarbons.
■ Thermal insulation, filling of cavity walls and close spaces.
■ Energy efficiency works on existing buildings, where any other type of thermal insulation work is possible. It can be realized also on single houses or flats.
■ To fill a volume of 1 m3, 2 bags of Politerm Wall are necessary.
■ Bag of 500 L (n° 2 bags = 1 m3 of finished mortar).
