Insulation for parapet walls
The junction of an external wall and flat roof is a difficult part of a building to design well. Continuing the wall above roof level to create an upstand also creates a thermal bridge, that was very difficult to detail before the development of PERINSUL HL insulation for parapet walls.
PERINSUL HL courses in with a masonry external wall at the level of the flat roof insulation, creating a connection with the wall insulation and eliminating the thermal bridge. The product is laid in mortar just like masonry, meaning no change in construction method or delay to the progress of work.
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’.
