Questions & Answers

Can I use this for insulating in the garage doors

Asked by: Judy
There are kits that are pre-cut to fit the metal garage doors. They would be easier to install. But this would work too.

Can this be used for the walls of a storage room inside the attic without anything covering it?

We have a door on the 2nd floor of our house that leads into an unfinished attic. I want to create a small storage room just inside that door (9' x 8' x 6') with a door on the back side leading into the rest of the large attic space. These foam panels would be nailed over existing sheetrock on three walls (the front wall that the existing door is in, plus the left and right side walls), but two sides of this new storage room (rear wall and ceiling) would be made only of these foam panels, which would be nailed to new 2x4 framing. I read that this foam insulation is meant to be under sheetrock or plywood as I understand it. Would leaving these two sides of this new room as standalone foam panels only, with no sheetrock, create a fire hazard and/or violate the fire code?
Asked by: Mike
According to the manufacturer it can, provided the attic space is "limited to servicing utilities" https://static1.squarespace.com/static/57a39be0579fb3a3a8540f56/t/5a4d199de4966bb3083ef6e8/1515002269847/Rmax+R-Matte+Plus-3+Application+-+Attic+and+Crawl+Space.pdf

Rated 5 out of 5 by from Insulate your Garage Door!! Much cheaper than buying the kits. Two layers of this is the perfect thickness. Just cut it slightly oversize, slip the top edge under the lip and then slide the bottom edge down. You could also glue it with spray contact glue. Four sheets was just enough to do one single bay door.

Rated 5 out of 5 by from Made a solar heater with it Too many years ago Mother Earth magazine had an article describing how to make a solar powered window heater. We bought this stuff, some black paint and a pane of glass. We already had the duct tape and knife. Made the window heater as per instructions. Stuck it in an east facing window. It worked perfectly! That was when I lived in northern Louisiana. Later, when I built a barn, I used it as insulation under the tin roof. Again, no complaints. The backing makes it stronger than plain poly boards. Those things broke way too easy.

Rated 5 out of 5 by from Great insulation for garage doors! I ordered this online and it was ready for me at the store as soon as I placed the order. I cut it in front of the store to fit into my car. I placed some 3" x 12" foam board spacers to give the air space and placed the foil side towards the inside of the garage doors to reflect the heat.
