External Masonry Cavity Walls
EXTERNAL MASONRY CAVITY WALL INSULATION
Knauf Insulation External Masonry Cavity Walls fullfill Solution-UK

APPLICATION OVERVIEW  - Built-in

Full-fill built-in insulation solutions are installed as the walls are built, with slabs being friction-fitted between the inner and outer leaves of the wall and in between wall ties.

The principle consideration is thermal performance with a requirement for the insulation to be in intimate contact with both leaves of the wall to prevent air movement and subsequent heat loss.

Our non-combustible DriTherm® Cavity Slabs are designed to fully fill the cavity and are BBA certified for use in all exposure zones.

APPLICATION OVERVIEW - Blown-in (New Build)

New build full-fill blown-in insulation solutions are installed via a series of pre-drilled installation holes by approved technicians once walls are built and when the building is watertight.

The principle consideration is thermal performance with a requirement for the insulation to be in intimate contact with both leaves of the wall to prevent air movement and subsequent heat loss.

Our non-combustible Supafil® blown insulation systems are designed to fully fill the cavity and are BBA certified for use in all exposure zones.

WHY MINERAL WOOL?

  • Mineral Wool provides the best combination of thermal, fire safety and acoustic performance.

  • Mineral Wool is easier to install correctly than other insulants such as rigid boards because it adapts to any slight imperfections in the substrate and knits together, eliminating any air gaps. Evidence shows the absence of air gaps is crucial to achieving real performance in the relevant application.
