IKO Enertherm ALU is a 100% CFC, HCFC or HFC-free insulation board with a rigid polyisocyanurate (PIR) foam core, clad on both sides with a multi-layer gastight aluminium complex.This high-quality reflecting ALU cladding consists of no fewer than seven layers, combined into a single complex. It is tested under extreme conditions in respect of water absorption, mechanical properties, corrosion resistance and emissivity.The high insulation values and thin construction of IKO Enertherm ALU boards offer a lightweight, sustainable solution that reduces the thickness of building construction.IKO Enertherm allows for technical maintenance on solar panels, air condition units and other roof installations due to their pressure resistance and shape retention – you can simply walk on them.PIR insulation can be easily combined with roof membranes and is dimensionally stable.The insulation boards remain moisture insensitive in all weather conditions. They also retain the same insulation value as well as the same weight and do not shrink. Applications Flat roof insulation for timber, concrete and steel deck. Pitched roof insulation (type nF with neutral felt). Floor insulation (underfloor heating and concrete floors). Cavity wall insulation. Outside wall insulation (closed joints). Loft insulation.
