What’s the word in Toolmonger land regarding the pros and cons of insulating garage doors? The picture above shows the beginning of an installation using a reflective foil kit, one of the apparently three main DIY approaches (the other two being foam panels and fiberglass rolls). Texas Garages is one site that discusses and compares the various approaches. Costs to do a single garage door range from $69 to $129.
I tried white fiberglass rolls in the garage door of our previous house and they did seem to help, although it was quite subjective as I didn’t make any before-and-after temperature measurements. I suspect that it just generally felt better out there because the white rolls helped brighten up the dingy old dark door.
What do you think? Have you done this? Would you do it? If the garage’s ceiling and walls are already insulated, doesn’t it make sense to insulate the door, too? Does it make more sense if you live in a cold climate than if you live in a warmer — or, like in central Texas, a damn hot at times — climate?
