Walls
External Masonry Cavity Walls

New Project (35) (1) (5).png

APPLICATION OVERVIEW

Full-filling masonry cavity walls with mineral wool enables the best possible R-value to save energy costs and reduce thermal gain.

This application will become increasingly important in South Africa with the new SANS 10400-XA standard and the impact of EPCs (Energy Performance Certificates).

Our full-fill built-in solution is installed as the walls are built and is suitable for all types of buildings as detailed in the British Board of Agrément (BBA) Certificates.

Why Mineral Wool?

  • Mineral wool slabs are sized to fit between wall ties without the need for cutting or fixings, reducing costs and increasing the building’s thermal efficiency.

  • Fully filling the cavity prevents mortar snots and other debris falling into the cavity, preventing bridges that can serve as a path for water to track from the outer to inner leaf.
