Concrete Soffit

Bradford PIR Boards are high performance building insulation boards that achieve significant thermal performance in a slimline, rigid board profile.

The product is made from an advanced thermoset polyisocyanurate (PIR) foam which is sandwiched between two layers of embossed aluminium foil facings. Its high thermal performance, slimline profile and high compressive strength, allows it to be efficiently designed into a building as a continuous thermal barrier across concrete soffits and concrete walls.
