Cavity Wall Insulation is used to reduce heat loss through a cavity wall by filling the air space with a porous material. This immobilises the air within the cavity (air is still the actual insulator), preventing convection, and can substantially reduce space heating costs.

It's never been more important to think about insulating your attic. Without proper insulation a lot of the valuable, expensive fuel you use to heat your home will be lost through the attic. The recommended depth for attic insulation is at least 8 inches however there are other materials which require different depths.

Thermal boarding is a composite board made of plasterboard with a backing of insulation. The insulation backing can be specified in a variety of thicknesses. Insulation in excess of 60mm will typically be required to achieve best practice performance. Thermal boards are fixed to the wall surface using continuous ribbons and dabs of adhesive.
