2mm 3mm Double Bubble Insulation Reflective Bubble Insulation for Window Fireproof and Heat Insulation
What Is Double Bubble Insulation
Double bubble insulation consists of two layers of polyethylene bubbles sandwiched between reflective foil layers (typically aluminum). The bubbles create air pockets that resist heat transfer, while the foil reflects radiant heat, providing dual thermal resistance. This design enhances insulation performance compared to single-layer alternatives.
How Double Bubble Insulation Works
Reflective Surface: The aluminum foil reflects up to 97% of radiant heat, helping to maintain temperature
Air Bubble Core: The bubble layer provides additional insulation by trapping air, reducing heat transfer via convection
Vapor Barrier: Many double bubble products also block moisture, preventing condensation and mold growth
Advantages of Double Bubble Insulation
Energy Efficiency: Reduces heating/cooling costs by blocking heat transfer
Lightweight & Flexible: Easy to cut, handle, and install without specialized tools
Moisture Resistance: Foil layers act as a vapor barrier, preventing condensation and mold growth
Durability: Resists punctures, UV degradation (if foil-coated), and chemical corrosion
Cost-Effective: Cheaper than rigid foam or fiberglass while offering comparable R-values (typically R-6 to R-8)
Eco-Friendly: Often made from recyclable materials and reduces energy consumption
