Thermalite Shield Block 3.6N is a versatile Aircrete block and can be used in a variety of applications including external walls, foundations, partitions and separating walls. A closed micro-cellular structure, that features tiny pockets of trapped air, gives Thermalite aerated blocks 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 acheieve and can help reduce emissions during a building’s life.

Key Benefits:

• Compressive strength : Load-bearing capacity for walls and partitions 3.6N

• Thermal conductivity :  closed micro-cellular structure minimises heat loss (0.15 W/m·K)

• Lightweight: Faster handling, speeding up build times.
