Description This premium single bubble reflective aluminium foil insulation roll delivers year-round indoor comfort by acting as a high-efficiency radiant barrier for all building spaces. Measuring 0.6m wide and 8.4m long with a total thickness of 3mm, the construction combines sealed polyethylene bubble core sandwiched between two layers of reflective aluminium foil, capable of reflecting up to 97% of radiant heat energy. It integrates multi-functional performance including thermal insulation, cold resistance, moisture blocking and noise reduction, effectively stabilizing indoor temperatures and cutting air conditioning and heating bills all year round. The air-locked bubble layer serves as a natural thermal break and vapor barrier to prevent condensation and damp damage to walls, roofs and ductwork. The double-sided aluminium foil lamination makes the whole roll highly tear-resistant and durable enough for long-term outdoor and indoor construction use. Ultra-lightweight and flexible, it can be easily cut and handled during DIY or professional installation without heavy cumbersome tools. This versatile radiant barrier fits perfectly for residential roof, ceiling, underground wall and warm air duct projects, as well as various commercial building insulation applications. Features Dual aluminium foil with single PE bubble core reflects up to 97% radiant heat to lower cooling and heating energy consumption All-in-one performance: heat insulation, cold protection, waterproof moisture barrier and sound absorption Tough tear-resistant laminated structure resists punctures and wear for long service life Ultra-lightweight flexible roll design, easy to cut, carry and install for DIY and professional builders 3mm compact thickness saves installation space without sacrificing thermal performance Effective vapor barrier stops moisture build-up and condensation inside wall/roof cavities Wide application range suitable for residential homes, commercial buildings, roofs, ceilings, underground walls and HVAC ducts Specifications Product Category: Reflective Bubble Foil Radiant Barrier Thermal Insulation Rolls Roll Overall Dimensions: 8.4m L x 0.6m W Thickness: 3mm Heat Reflectivity Rate: 97% Composite Materials: Polyethylene Bubble Layer + Double Aluminium Foil Surface Colour: Silver Core Structure: Single Bubble Double Foil Key Properties: Waterproof, Thermal Insulating, Soundproof, Tear Resistant Application Scenarios: Residential & Commercial Construction, Roofs, Ceilings, Walls, Heating Ducts
