SMARTBLOCK® B.33.300

ULTRA-LIGHT BLOCK FOR MASONRY

SMARTBLOCK® B.33.300 is a solid ultra-light block (18.7 lb/ft³ (300 kg/m³)) made of cement and POLITERM® BLU / BLU FEIN virgin EPS beads coated with the E.I.A. additive. It weighs only 22 lb (9.9 kg), 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 13 in (33 cm) thick it builds single-layer insulating infill walls, with no additional insulation layer: the plastered wall reaches U 0.04 BTU/(h·ft²·°F) (0.227 W/m²K), a phase shift of 14.7 h and a calculated sound insulation of Rw 48.6 dB. Reaction to fire A2-s1,d0, CE marked to EN 771-3.
