Garage door add on foam insulation.

[Great-Kazoo]

Anyone here do a foam insulation retrofit? My doors are old but in great condition, but they get hit by the PM sun and make the garage unbarable. So I want to add the foam to them. Tips, tricks, sources?

We had left over foil backed exterior 1/16" thick sheets i used on the 8 x 16 door. I put the foil faced side on to the door, using exterior silicone type contact cement. With 4" fiber woven tape on the ends. Basically everything used was from material we had laying around.
If you have a standard 7' h door it's not bad. Once you go over that is where it gets a little more $$ Mines 16' w x 8'h


I considered using the foam garage door sections. But they're damn proud of them price wise. Depending on sq ft of the door. Here's a decently priced light material that's easy to cut and work with. Unlike the foam board that's messy when cut and doesn't bend enough, if at all. To fit the entire door panel.

If you don't care about cosmetics a roll of bubble wrap will work. Anything to reduce that direct sunlight heat from radiating in to the garage helps. Even in winter there's a noticable difference how much less the mini splits run. I also have ceiling fans at each end to circulate air.


I can post a pic later of what my shop door looks like

I would only mention that even though it?s just foam it may make the door heavier and you may need to replace the springs to handle the extra weight.

Oh i will, depending what material you use. So one should factor in another $70-120 for readjusting the spring[s] after the door[s] are finished. I suggest calling around for price quotes before starting. So you know a time frame for service, once finished.
