Product type PERINSUL

Thermal bridges (or cold bridges) can be responsible for up to 20% of the heat loss from a building. Ensuring continuity of the building’s thermal envelope is critical to eliminating ‘cold spots’, which are possible sources of condensation, damp and mould growth.

FOAMGLAS® PERINSUL acts as a thermal break at junction details and other thermal bridges, maintaining continuity of insulation. The elements have a high load-bearing capacity, are dimensionally stable, and contribute to damp proofing measures due to being completely watertight.


Capable of bearing the structural loads of a three storey building, FOAMGLAS® PERINSUL HL is laid in a mortar bed and eliminates thermal bridging at junction details. It is a unique load-bearing insulation element, and has been tested in accordance with Eurocode 6 specifically to bear loads imposed by structural masonry.
