Durox Supabloc aircrete blocks
Supabloc is the most versatile aircrete block available, providing the best combination of compressive strength and low thermal conductivity. It can also satisfy the acoustic performance required by Building Regulations for internal walls in dwellings.
Durox Supabloc applications
- Inner leaf of cavity walls
- Outer leaf of cavity walls, suitably clad
- Solid external walls, clad or rendered
- Internal partitions
- Foundation walls in soils up to Design Sulfate Class DS-2.
Durox Supabloc specification
- Mean compressive strength: 3.6N/mm²
