3 layers aluminum foil heat insulation wrap consists of pure aluminum film bonded to a layer of bubbles, Buffalo FOIL is a high cost performance choice for heat insulation. The foil will be installed before any roofing product installation, and the aluminium reflective foil layers can blocks 97% of radiation heat. The average temperature that bubble foil can reduce is around 6 degree Celsius.
