Application and installation

Knauf Supafil Cavity 033 is installed exclusively by approved installers. The blown mineral wool is evenly distributed throughout the cavity via small holes drilled into the mortar joints, typically from 18 mm in diameter. Once the insulation has been installed, the drill holes are carefully sealed with matching mortar, helping the exterior wall retain its original appearance. The entire process is quick and causes minimal disruption to residents.
