• Insulation

    We stock a full range of roof insulation products

A quarter of heat is lost through the roof in an uninsulated home. Insulating your loft or flat roof is a simple and effective way to reduce heat loss and reduce your heating bills.

We stock a wide range of PIR Boards. Polyisocyanurate (PIR) is one of the most efficient insulation material used in construction. This product is an improvement of previously used PUR boards (polyurethane), typically produced as a foam and used as rigid thermal insulation. We also stock torch on insulation boards and roll cut loft insulation.
