Cellular Dense Concrete Block 140 mm
Cellular Dense Concrete Block 140 mm
ISO 9001 Quality Management
Certificate type
Dense concrete blocks.
Application
Suitable for use in the following walls:
- Internal partition walls.
- Inner and outer leaves of external cavity walls up to three storeys.
- Building Regulations (E&W) Approved Document E and Robust Detail acoustic separating walls.
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.
