IKO enertherm ALU TAP Product description: IKO enertherm ALU is a 100 % CFC, HCFC or HFC-free insulation board with a rigid polyisocyanurate 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. Application: Rooftop: IKO enertherm ALU TAP provides a perfect drainage to the pipes on flat roofs with for timber, concrete or steel deck support. Edge finish: Straight Thermal performance: Thermal conduction coefficient: (EN 13165) AD: 0,022 W/(m.K) Fire properties Fire class according to EN 13501-1: Class E Technical details: Bulk density: ± 32 kg/m3 Compressive strength at 10% deformation: 175 kPa (17,5 ton/m2) Behaviour under uniformly distributed loading: class C (< 5 % deformation at 80 °C and 40 kPa loading) Closed cells: more than 95% Water vapour diffusion: PIR foam: p = 60 - ALU facing: p > 100,000 Existing gradients: 1/120 (0,83%), 1/80 (1,25%), 1/60 (1,67%), 1/50 (2,08%).
