Foil-Faced Glass Wool Roll

Foil-Faced Glass Wool Roll is a glass wool insulation blanket with reinforced aluminium foil bonded to one face. The glass wool provides thermal and acoustic insulation; the foil stops moisture entering it and reflects radiant heat.

It is the standard insulation under metal roof sheeting, where the foil faces the building and keeps condensation out of the insulation, and on ductwork and walls in building services. Every lap is sealed with aluminium foil tape so the vapour barrier is continuous.

Glass wool is a lower-temperature insulation than rockwool or ceramic fibre, and the foil facing limits the service temperature further, so it is not used on hot process equipment. Thickness, density and roll size are confirmed on quotation.

Zenco Systems supplies foil-faced glass wool from Nairobi across Kenya and East Africa, together with plain glass wool blanket and aluminium foil tape.

Use the foil-faced roll where a vapour barrier is needed — roofs, ducting, cold and humid spaces. Use plain glass wool where it is not, and rockwool where the temperature is higher or fire performance governs.
