355mm 3.6N Thermalite Trench Block T&G

Thermalite aircrete blocks provide a cost-effective solution for below-ground construction. 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 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.
