REINFORCED BITUMEN MEMBRANE SYSTEMS ENGINEERED FOR A MODERN WORLD 23 IKO Enertherm High performance thermal insulation IKO Enertherm insulation boards are made from lightweight, fire resistant, rigid PIR foam core, with high compressive strength and dimensional stability. The highly efficient closed cell structure has a low thermal conductivity and easily achieves required U-values with a minimum thickness. The current requirements for thermal insulation are set out in Building Regulations Approved Documents L1 and L2 2010: Conservation of fuel and power. Key benefits of IKO Enertherm insulation • Fire performance polyisocyanurate foam core • Mineral glass or composite aluminium facings available • Lightweight and easy to handle • High insulation value/low thermal conductivity • Rot proof, durable and maintenance free • Ideal for meeting the increasingly demanding Building Regulations and Part L requirements • Tapered/cut-to-falls boards also available • Zero Global Warming Potential • Zero Ozone Depletion Potential • Fire classification for ALU boards - Euroclass Bs2 d0 (application on metal decks). IKO Enertherm PIR MG A totally CFC/HCFC-free, rigid polyisocyanurate foam insulation board, faced on both sides with perforated (mineral coated) glass tissue. IKO Enertherm PIR MG has a thermal conductivity value of 0.027W/mK (80mm thickness and above). Board Size: 1200 x 1000mm IKO Enertherm PIR ALU A totally CFC/HCFC-free, rigid polyisocyanurate foam insulation board, clad on both sides with a structured aluminium sheet. IKO Enertherm PIR ALU offers outstanding insulating properties, with a thermal conductivity of 0.023W/mK. Board Size: 1200 x 1000mm Aluminium faced angle fillets also available in this range. IKO Enertherm BGF A totally CFC/HCFC-free, rigid polyisocyanurate foam insulation board, faced on both sides with a bituminous glass fleece and finished with a polypropylene film. IKO Enertherm PIR BGF has a thermal conductivity value of 0.027W/mK (80mm thickness and above) and is suitable for use within fully-bonded torch-applied roofing systems.
