SMARTBLOCK® B.25.300

ULTRA-LIGHT BLOCK FOR MASONRY

SMARTBLOCK® B.25.300 is a solid ultra-light block (300 kg/m³ (18.7 lb/ft³)) made of cement and POLITERM® BLU / BLU FEIN virgin EPS beads coated with the E.I.A. additive. It weighs only 7.5 kg (17 lb), is cut with a simple saw and is laid with MALTA BLOCK 600 thermal mortar: walls go up quickly, with little waste and no thermal bridges at the joints.

At 25 cm (9 7/8 in) thick it builds single-layer insulating infill walls, with no additional insulation layer: the plastered wall reaches U 0.293 W/m²K (0.052 BTU/(h·ft²·°F)), a phase shift of 11.1 h and a calculated sound insulation of Rw 46.3 dB. Reaction to fire A2-s1,d0, CE marked to EN 771-3.
