Reflectix Inc BP48050 Double Bubble Foil Insulation Roll

Product Description

The REFLECTIX INC BP48050 is a double bubble foil reflective insulation roll measuring 48 inches wide by 50 feet long. At 5/16 inch thick, it features two outer layers of aluminum foil, each bonded to a tough polyethylene layer for structural integrity. The product reflects up to 97% of radiant heat and carries an R-value of up to 14.3 depending on application and installation method. Licensed contractors and knowledgeable installers use this roll for thermal and vapor management in a wide range of construction and mechanical applications.

This insulation roll is suited for both residential and light commercial use. It performs as an excellent vapor barrier in below-grade environments and is commonly installed in crawl spaces, basement walls, attics, side walls, and metal buildings. It is also used for duct insulation where flexible, lightweight coverage is needed. The roll format allows for efficient coverage across large surface areas with minimal waste.

Compatibility

Designed for use in crawl spaces, basement walls, attics, side walls, metal buildings, and HVAC duct insulation applications where a flexible double bubble foil reflective insulation is specified.

Installation Notes

Installation is typically performed by insulation contractors, HVAC technicians, or experienced builders following local building code requirements. The roll can be cut with standard utility shears or a knife and secured using foil tape or staples. All mechanical and electrical systems in the work area should be de-energized or shut down before beginning installation in enclosed cavities. Seams should be sealed with appropriate foil tape to maintain vapor barrier continuity.
