Aluminium Faced Rigid Polyisocyanurate Insulation [PIR]
Supertherm ALU is a totally CFC/HCFC free, rigid polyisocyanurate foam insulation board, faced on both sides with a composite aluminium kraft sheet. The highly efficient closed cell foam core has an exceptionally low thermal conductivity of 0.022 W/mK and easily achieves required U values with a minimum thickness.
Supertherm ALU is designed to be used in combination with mechanically fastened and self-adhesive waterproofing membranes. It is also used as part of certain other cold applied / torch applied hybrid waterproofing systems. The boards are suitable for use, over a suitable vapour control layer, onto supporting substrates such as profiled metal decking, timber panels, screeded concrete, or to upgrade existing sound bitumen roofing systems.
