Description
Cellular dense concrete blocks offer a lower weight alternative to solid dense blocks with improved thermal properties. Blinded cells on the upper bed face allows for a full bed of mortar and easier build.
Features and benefits:
- Durable and resilient block suitable for high strength, acoustic and decorative applications.
- Manufactured from Class 2 aggregates and consist of up to 20% recycled raw material.
- Produced to BS EN 771-3.
