Air bubble foil (or bubble insulation) is a high-performance thermal insulation material consisting of one or two layers of polyethylene air bubbles sandwiched between reflective aluminum foil layers. It acts as a radiant barrier, reflecting up to 97% of heat while providing moisture and vapor protection, ideal for roofing and walls. Comprises single or double layers of polyethylene air bubbles (typically 4mm–10mm thick) laminated with anti-corrosive, pure aluminum foil on both sides. Application is underdeck/roofing – Ideal for preventing heat from entering commercial, industrial, and residential roofs, Wall Insulation – Used for cladding to reduce heat transfer, HVAC – Insulation for ductwork and piping and Storage – Suitable for warehouses, poultry farms, and workshops.
