ProTherm Quantum® PLUS+ is a rigid Vacuum Insulation Panel (VIP). The VIP panel consists of a compressed fumed silica sand microporous core which is evacuated of air and moisture before being encased and sealed in a special thin, gas-tight, hybrid aluminium foil envelope, encapsulated in a solvent free polyurethane waterproof coating. The coating is a factory applied solvent free two component elastomeric polyurethane waterproofing membrane. The resulting panel gives outstanding thermal conductivity, with the thinnest possible insulation solution.
With a declared (aged) thermal conductivity of 0.007 W/m.K, the ProTherm Quantum® PLUS+ VIP panel provides an insulating performance that is up to five times better than other commonly available insulation materials. This high level of thermal efficiency combined with minimal thickness enable the ProTherm Quantum® PLUS+ VIP Inverted Roof Insulation system to meet the requirements of Building Regulations Part L, Part M and NHBC Chapter 7.1.
BBA Certified 20/5769.
