PERINSUL HL under window and door sills
Doors and windows form part of a building’s thermal envelope. Positioning them within their openings to achieve continuity of insulation can be a detailing challenge, making it more likely that the edges of the opening act as a thermal bridge - particularly at ground level below a door or full-height window.
Where doors and windows do not line up with surrounding wall insulation, masonry can allow heat energy to bypass the thermal envelope. Providing sufficient insulation where a floor screed or slab meets a door or window cill is difficult - especially where level access requirements through a doorway mean there is no step into the building. As a load-bearing insulation element, PERINSUL HL is the perfect solution to the thermal bridge.
Proven concept: full suite of calculated and accredited details, including psi values, available for common applications featuring a structural thermal bridge.
Energy efficiency: reduces building heat loss and space heating demand.
Watertight: closed cell insulation material that maintains its thermal properties.
Load-bearing: strong and unique insulation element, capable of bearing structural loads.
Healthy living: elimination of heat loss at ceiling edges prevents ‘cold spots’.
