Thermal Insulation Boards & Rolls

Thermal Products includes insulation boards, rolls and laminates used to improve heat retention and energy efficiency in walls, floors, roofs, lofts and cavity constructions. This range includes PIR boards, XPS boards, EPS boards, insulated plasterboard, loft rolls, cavity wall boards and multi-foil insulation from leading UK insulation brands.

Choose rigid boards for high-performance thermal insulation in floors, walls and roofs, or mineral wool rolls for lofts, partitions and frame applications. For best results, select the correct product for the construction type and check thickness, board size, pack coverage, thermal conductivity and installation requirements before ordering.
