QI Quantum PLUS+ Inverted Roof Insulation System 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.
