Double the bubbles for double the airspace. The more airspace in the product, the better it is at slowing heat transfer.
Double bubble insulation provides the maximum efficiency and highest R-value for bubble insulation. Key benefits of this foil-faced double bubble include:
- 1/4″ – 5/16″ nominal thickness of foil bubble insulation
- 99.9% Pure Aluminum bonded to tear-resistant polyethylene core and bubblewrap insulation
- Highly reflective foil facing
- Optional UV resistant polyethylene facing on one side, foil on opposite side (foil double bubble white poly option)
- Reflective bubble insulation has a very low rate of emissivity
- Durable polyethylene bubbles make up the center bubblewrap insulation
- Acts as 100% vapor barrier
- Class A/Class 1 fire rating
- Foil faced bubble wrap insulation makes an excellent thermal barrier
- Barrier for methane, radon, moisture, termites and other pests
- Thermal resistance in a 3.5″ cavity: R-15.2 (Heat Flow Down), R-8.5 (Horizontal Heat Flow)
