SMARTBLOCK® B.50.300

ULTRA-LIGHT BLOCK FOR MASONRY

SMARTBLOCK® B.50.300 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 33 lb (15 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 19 5/8 in (50 cm) thick it builds single-layer insulating infill walls, with no additional insulation layer: the plastered wall reaches U 0.027 BTU/(h·ft²·°F) (0.153 W/m²K), a phase shift of 22.5 h and a calculated sound insulation of Rw 51.9 dB. Reaction to fire A2-s1,d0, CE marked to EN 771-3.
