I've been searching local home improvement shops and the web; as well as past threads for do-it-yourself garage door insulation kits; was wondering if anybody could suggest a site to find kits available for me to install? I have two single car garge doors to do. My neighbor used foam boarding; I guess it works ok?
Thanks
Mitch
Are you talking about sectional roll-up doors? If so, they can be ordered with or without insulation (pre-cut foam). Any garage door dealer in Clarksville should be able to order insulation kits for your doors.
I used foil-back rigid foam on my current garage door. I cut pieces a little small, then shot expanding foam around the edges. It worked great, theough the door is now a little too heavy for the springs. (Need to get stronger springs at HD, but have just never gotten around to it.) The added insulation makes a big difference in my unheated garage.
I used 2" foam boards cut to fit snugly in the spaces between the studs of my wooden swing up door. Sure made a difference during the hot weather here. I only use my garage for parking the car though.
Being a HVAC engineer and have calcuted many surface temperatures and R values IMO I would say for the buck styrofoam weighs less that the foil back flamable board and allows less heat transfer. Check the difference in temperature between these two insulation materials when installed against the door's metal surface with the sun rays on the door. Styrofoam is used in walk in freezer's, coolers and other equipment for containing temperature within and outside of the envelope.
Agreed that Styrofoam is cheaper and perhaps lighter than foam board. On r-value polyisocyanurate foil faced foam board has the highest r-value per inch of any thing I looked at. However even it says it needs 1/2" drywall between it and a living space. We can argue whether a garage is a living space but I think the point has to be made that building codes do not allow foam to be exposed in living spaces because of its flammable properties. Freezers etc have metal jackets for that purpose. I have no problem with anyone using foam board or Styrofoam in the application we are discussing - Its your garage!- just be knowledgeable of the risks.
I've seen numerous foam board application in my buddies garage's; I would like to find a kit that's actually manufacture by garage door companies; havn't found one on web yet; that offers insulation kits just complete door systems; I want something to last and especially since the garage doors are part of the house; I want a product to add value to home's value and not just weather protection...
All,
Foam board,... Smoam Board.
There is a duct liner made by Certaineed called Tough Guard.
It is a simple fiberglass duct liner that comes in 4ft. wide by 100 ft. rolls. You pick the thickness. It will cost you about $100 for 1" thick. You can glue it up with contact cement and it is mold resistant. This will not weigh the door down. It is not as durable as foam board but would be my choice anyways.
Consider it,

Hello,
I live in tn also, matter of fact about an hour from you.
I purchased two garage doors from a well know door manu/instal place in nashville. You didn't hear this from me but all they do is cut the exact same foil backed material you can buy at home depot and bow the middle and snap it in. It was an extremly simple task. Took only about 30 min. My friend would not let me order my doors with insulation for this reason. Just go buy material and install yourself.
Well; now that the Holiday's are over and I'm tired of hunting down garage door installers; I guess the best solution is to take ya'll advice and just purchase foam board and cut and place; would like to add some type of trim to cover any misstates and especially to keep the boards from falling out.
You will find that adding trim won't be needed. I got my foam board from Lowes and actually measured once and added 1/4" to both edges. I found that all of my door panels would be the same size, and it was a tight fit. So now the panels are in (actually two panels back to back, which was 1 1/2" thick) and there is almost no chance of them coming out. The good thing is the foam is cheap enough to experiment with.
