Thermal Resistance PE bubble insulations are composed of either one or two layers of air bubbles sandwiched between two aluminium foil.
This insulation is rated and tested by reflectivity and emissivity. It is 96% reflective and 4% emissive, which means the product only allows 4% of radiant heat to pass through it. To put it simple, the insulation does not try to slow the way heat passes through it, the insulation tries to eliminate heat from passing through it.
Construction of pure aluminium foil attached to polyethylene bubble sheet using layer-bonding thermal process making it free of adhesive or chemical. Bubble insulation is Fibre free and block 96% of the radiated heat, that penetrates through a given structure or building.
