Garage Do's, what I did for mine Options

[76-914]

With record breaking temps moving in this weekend I decided to insulate my garage door. It is westward facing and gets hot as Hell in the PM when the sun hits it. I used some 1" Styrofoam board. By 1:30 the garage door panel outside temp was 137 and the inside temp was 82. I showed my wife 15 mins later but the inside temp was now reading 100F. (IMG:style_emoticons/default/WTF.gif) So I measured the outside temp again and it was now at 157F. Looks like I realized appx 50F drop. I may add another 1" later on. Once the radiant heat was reduced at the panels I could feel the small exposed area of our roof radiating heat so I installed some radiant barrier material on the inside of the roof. Now I can work in the garage with a bit more comfort.
What have you done for your garage lately?

I am sooooooooooooooooooo going to do that! (IMG:style_emoticons/default/piratenanner.gif) Where did get the insulation? (IMG:style_emoticons/default/huh.gif)

Lowe's. It comes in 4x8 sheets. 4 sheets required for mine. Cuts well with an electric carving knife. It is foil backed and plastic covered for vapor control. $50 to do the door.

6" walls packed with insulation, vapor barrier and drywall. Insulated door, 8" in the ceiling and it's still not enough in the winter. Summer, it stays 65 when it's 90 outside.

Similar, 6" also with R-19 but did 7/16" OSB instead of drywall. Though drywall looks better, I prefer the durability of OSB; walls and ceiling are painted white for light reflection. Garage doors are insulated, 11.5 ft ceiling with R-30 above it. Also run a dehumidifier in the summer. With a fan running it is comfortable working in the summer.

Home Depot on line has garage door insulation panels with a plastic liner. They are made in the correct dimensions and require little if any cutting. I have used them on two and three car garages and they are easy to install, quiet the doors down and greatly reduce transmitted heat .

Repaint sun facing metal garage doors a light color too! It has been Africa hot in So. Cal!

Be sure to check each panel's dimension. Look closely at mine. The top and bottom panels are 21" tall while the panels in rows 2,3 and 4 are 18" tall. L-R dimensions vary slightly as well. FWIW, the kits are online only. That's why I bought sheets and cut it myself. Couldn't wait.

Do you just glue it on? Any special kind of glue?

No glue. If you cut them about 1/8" too large (left to right) and they will squeeze in place. The garage door panels have lips that will hold them in place on the tops and bottoms of each piece.

I need to do this. My garage is an oven. No insulation on the roof or door.

I googled this article about door insulation. According to this article you need to create an air gap for the radiant shield to be effective.

True. The radiant barrier I used on the ceiling stands 3.5" away. More important if you are using insulation in conjunction with the foam board.

I too insulated my garage door with an insulating roll of material (metal foil over bubble wrap) from Lowes, it helped the temperatures alot in my garage and I used metal foil duct tape along the edges to install it.

One word of CAUTION, the added weight of the insulation to your garage door could cause your garage door springs to break.... or at the very least require a spring adjustment... don't ask how I know.

These 4 styrofoam panels combined are slightly heavier than a Popcorn Fart. Shouldn't be a problem. Mine raises w/o problem??
