General Application (GA) or General Purpose (GP) insulation board is a high-performance PIR insulation board featuring a low emissivity foil facing. These insulation boards are lightweight, easy to cut, handle and install. Available in thicknesses from 25mm to 150mm, it can be considered for roof, wall and floor applications.
The key benefits are:
Cavity wall insulation board is a rigid polyisocyanurate (PIR) insulation board with aluminium foil composite to both sides for cavity walls, with precision-cut straight edges to ensure gaps between boards are kept to a minimum. The cavity is the space between the external and internal walls. Cavity wall insulation is the process of filling the cavity with insulation by using materials such as Polyisocyanurate (PIR). The boards are conveniently sized to co-ordinate with brick and block dimensions and allow the insertion of wall ties at the appropriate spacing.
