Topic tags/keywords: garage door insulation

I live in Texas, so heat is more of an issue than cold. I have a thin, el-cheapo alum. garage door. I decided to invest @ 60 dollars in those 1.5 inch foam insulation sheets at the big box and cut them to fit my door. It took me less than an hour. So far it has made a difference in dampening the noise, as my neighbors houses are VERY close and we all know running a lunch box planer is loud.

Today I noted the effect on temperature.

This AM it was 36 degrees outside and 58 degrees in my garage.

I have to say that is pretty good bang for the buck!

Happy days – Iused 75mm (3”) polystrene boards between the framing studs and 18mm ply sheathing in my shop. Works for me too and I don’t have angry neighbours banging on the shop door.

Nice touch

I did that and then added thin reflective “insulation” over the foam. Made a huge difference in both heat and cold. Last night it was 5 degrees outside and I was able to maintain a constant 65 in the garage with my heater on its lowest setting. I did insulate the walls and ceiling with standard insulation as well. Also the noise difference was amazing.

That’s better than I thought it would be!

Thanks for the report!

I was in HD not too long ago & just happen to notice they had KITS for that… for about $59-$60… sounds like the same thing… precut one way but have to trim to fit the other…

Was there glue included in the kit? What kind was it?

Now that I know it’s worth doing, I think I will work it in… when I can…

Thanks again!

David…never thought of it that way, but you are correct.

Joe, with my door, I have “ledges, or lips” for each section…cut to size and pop in…no glue.

I actually cut it with my table saw HAHA>

You might also consider insulating the attic space above the garage as well. I did and it has kept it very warm in the winter as well as help cool in the hot summers here

I am in west Texas and it gets hot here! Insulation sure helps. I did the same as Bullethead did. It makes the operation of the door, quiter also.

I live in Florida and I bought a kit for my Garage door from Texas Garages. They shipped the all the materials needed and the web site is pretty darned informative.

tape the edges

b4 you apply the poly (really in-expensive) run a bead of PL glue around, use a pan head screw and screw through the poly and Pl beneath, into the rigid insulation……let set, ………its like a walk in beer cooler door… and makes a huge difference in, not only the temperature but the energy savings.

I live in Texas and got the kits for my doors from Lowes and they fit into the channels of my doors. They do a good job. I also insulated the attic above the garage and it works.

The only issue I have is that the garage also retains too much heat. I need to figure a way to cool it off, I was looking at the Anyone tried that?
