I am heating my garage shop in northern Minn with a LP Hotdawg heater. I need to seal the air spaces below the garage door.
The concrete has multiple cracks and has heaved in the middle of the double car garage door leaving gaps of 1/8 - 1/4" on both ends. The rubberized garage door insulation strip does not cover these gaps.
I was thinking of taking the strip off and installing that open cell 3/4 inch foam but I'm afraid it will stick and pull off when we get rain that then freezes. Any other ideas?? I don't use the garage door very often but do some.
Thanks, Rick
