Durox Supabloc 7 aircrete blocks
Supabloc 7 is intended for loadbearing applications that specify the use of a 7.3N/mm² building block. Combined with low-self weight and high thermal performance, Supabloc 7 is suitable for use in town houses, apartments and other highly loaded walls.
Durox Supabloc 7 applications
- Loadbearing single leaf and cavity walls
- Separating walls including those conforming to Robust Details E-WM-6 and E-WM-15
- Foundation walls in soils up to Design Sulfate Class DS-3
