This single bubble insulation product consists of 1 layer of 5/32" (4mm) polyethylene bubble sandwiched between two layers of highly reflective radiant barrier reflective aluminum. Strong lightweight, yet durable material that is easy to cut and install and can be stapled or nailed into any surface without compromising the insulation barrier. Effective thermal radiant barrier: reflects 96% of radiant heat transfer with a thermal resistance R value of 4. 9 to 14. 1 Water resistant: will not oxidize like pure Aluminium does/ not effected by humidity and moisture. 100% waterproof. Can be used in outdoor and indoor applications. Great insulation for basements and crawlspaces, garages, metal buildings, pole barns, poultry houses, green houses, roofs, walls, Air ducts, and attics

Uboxes, Thermoflex insulated bubble roll, 65-feet (48-INCHES) This single bubble insulation product consists of 1 layer of 5/32" (4mm) polyethylene bubble that is sandwiched between two metalized, low emissivity surfaces. The r-value ranges from 4. 9 to 14. 1. The polyethylene encapsulated air Bubbles serve as an effective thermal break as ELL as vapor barrier while the two outer metalized surfaces reflect up to 96% of all radiant energy.
