Thermalite Aircrete Hi-Strength Trenchblock

Benefits of Thermalite Aircrete Hi-Strength Trenchblock

Thermalite aircrete blocks provide a cost-effective solution for wall, floor and below-ground constructions. A closed micro-cellular structure, that features tiny pockets of trapped air, gives Thermalite its distinctive features: high thermal and sound insulation, lightness for handling, high compressive strength, and fire and moisture resistance. Thermalite’s excellent thermal insulation properties make U-value targets easier to achieve and can help reduce the CO2 emissions during a building’s life.
