This Double Bubble Reflective garage door insulation is two layers of polyethylene bubbles sandwiched between two layers of metalized polyester film and is manufactured to last and maintain the enclosed air space. The independently enclosed bubble layers are sealed with multiple layers of polyester creating closed air bubbles which prevent the loss of air.  It is lightweight and easy to install and requires no further maintenance.

- Insulation comprised of two (2) layers of 3/16" bubbles laminated between two (2) outer layers of radiant barrier
