The "bubble pack technology" was an easy cut and paste project! Forget about the foil tape and use the 3M spray glue instead. Project time for a two car garage door approx. 2 hours.
This morning, there was a 7 degree differential between outside and garage and a 7 degree differential between garage and inside my home.
(it is November and reference is made for southwestern climate)
Because the material is compact no shaving of styrofoam necessary!
