In uninsulated external cavity walls heat is lost through a combination of conduction, convection and radiation as heat passes through the various layers of the wall.
In separating party walls between dwellings this is no different and is known as party wall thermal bypass. Knauf Insulation’s Supafil Party Wall insulation is a proven solution to eliminate this heat loss in both new and existing homes.
Supafil Party Wall is an unbonded glass mineral wool insulation that is blown into the cavity. It is a registered construction with Robust Details and avoids the need for pre-completion testing. It is manufactured with a blue colour to help identification on site easier and ensure that the correctly specified material is installed.
