FOAMGLAS® PERINSUL HL is an innovative product developed by PITTSBURGH CORNING for the UK market to reduce thermal bridges at junctions within wall constructions. FOAMGLAS® PERINSUL HL blocks, manufactured from high density FOAMGLAS®, are designed to form an effective insulated joint between vertical wall insulation and horizontal floor or roof insulation. Possessing all the thermal properties for which FOAMGLAS® is well proven, together with an exceptionally high unit compressive strength of 2.9N/mm2 at breakpoint when capped with mortar, cold bridging is significantly reduced and structural integrity maintained. This product is tested to BS EN772-1. and EN826, Annexe A
Perinsul blocks have been used on Dogs Trust Shrewsbury and Loughborough to assist in reducing heat losses through cold bridging.
