Thermalite aircrete blocks provide a cost-effective solution for below-ground construction. Thermalite blocks have a closed micro-cellular structure featuring small pockets of trapped air. The block's internal structure results in high compressive strength, high thermal and sound insulation, fire and moisture resistance, and also aids in making the blocks light and easy to handle. Thermalite's thermal insulation properties make U-Value targets easier to achieve and helps to reduce the building's carbon dioxide emissions.
- Tongue and groove joints and handholds for easy handling
- For use in soils up to Design Sulfate Class DS 4
- Improves thermal performance
- Moisture resistance
- Removes the need to mortar perp ends
- Can be used in thin joint masonry, saving time and money
Sold individually. You will need 10 blocks per m2 of your project.
These blocks are cheaper if you buy in multiples of 20.
