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.

Insulation is required to prevent heat loss via convection by fully filling the cavity to prevent an unwanted chimney effect, in addition to sound reduction to prevent noise transferring between dwellings.

Our non-combustible insulation solutions for party walls allow a zero-effective U-value to be claimed in SAP and are compliant with a wide range of constructions included in the Robust Details Handbook to demonstrate high levels of acoustic performance.

APPLICATION OVERVIEW - Blown In

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.

Insulation is required to prevent heat loss via convection by fully filling the cavity to prevent an unwanted chimney effect, in addition to sound reduction to prevent noise transferring between dwellings.

Our non-combustible Supafil® Party Wall system allows a zero-effective U-value to be claimed in SAP and is compliant walls built to constructions included in the Robust Details Handbook to demonstrate high levels of acoustic performance.

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.
