Product Information

Thermalite blocks are made of A1 non-combustible material which reduces the risk of rise on site during construction. Thermalite blocks with a compressive strength of 7.3 N/mm2 are suitable for structures that depend on high loading strength, such as wallsfloorsand below-ground structuresWith its closed micro-cellular structure containing small air pockets. Thermalite possesses unique qualities such as superior thermal and sound insulation, being lightweight for easy handling, strong compressive strengthand fire resistance. The exceptional thermal insulation properties of thermalite contribute to achieving U-value targets more effortlessly and aid in minimizing CO2 emissions throughout the lifespan of a building.
