I have a 2 car garage with a sectional roll-up door. Because it is facing south, during the summer time, it's impossible to work in there from 1pm till midnight, just too damn hot. I did a little research, this company came up: Texas Garages. they have the common foam panels also I'm more interested in the reflective foil type insulation. Anybody has any first hand dope on how effictive of this stuff?
