Insulating Garage Door Itself

[Garage Josh]

I saw somewhere on here that someone insulated the door itself with the rigid foam boards, foil side facing inside garage (does it matter?) then taped over edges with foil tape. It looks like easiest way to quickly insulate the garage door itself, but is it the best? Would spray foam be the best? Or not really a noticeable difference since my door for example is about 1-2 inches deep?

I used I" foam a few weeks ago. Doing a lot of work on garage including adding insulation. This did make a difference in keeping garage about 10 degrees warmer, but is part of overall plan.

Can you paint over that stuff? I would want to do white so I reflect more light into the shop area.

I bought a factory kit ... Looks like a factory insulated door now.

Do you have a link on the kit above? I bought the cut to fit kits and all though it works, doesn't look that great.

You can insulate the door, but my biggest problem was the gap on the sides of the door. On a windy day you can feel the air infiltration, even with the weather stripping on the outside in place.

search for "Green Hinges" a ~$100 solution to drafty door sides

Check this video out on how to stop drafty doors...I have this on my heated garage and it works great!!! Specifically the side trim over the molding...

Those "Green Hinges" look pretty cool. http://www.greenhingeofamerica.com/ I'll have to double check, but if I recall my garage door surprisingly doesn't feel drafty around the sides. So not sure if that would be a good use of $ right now if I don't have drafts.

I would like to do a bottom seal, and exterior one too like the above video.

Not that a garage is the most decorated area as I prefer function over form, but I want to be able to paint/cover up the insulation

My door was made by NW Door. I got the NW Door kit from the same guy I got my Liftmaster LM3800 from. Also, NW Door is only 5 miles down the road, so easy to get to them. I'd find the manufacturer and see if they have one. If they made an insulated version of your door then more than likely they have a kit too. Mine was under $100 ...

Saw this thread and read about the Green Hinges and went to their web site and ordered 2 sets for my 2 garage doors. I have the seals but like what has been said, I would get the drafts during the windy times and since my garage faces the west my doors would move around. I figure this is a great investment since I heat my garage 24/7 @50* and it should pay for itself in no time. Glad I came across this and I like that it is American made.

Which way the foil faces does matter. You don't want it contact with the metal of the garage door. Has to do with thermal radiation needing space to bounce back. Ideally you will want a small space in between foam and foam board.

I already knew about the hinges from a previous thread and made a mental note to buy a set for my shop. Then I had a brain flush. When I saw this thread I went to the site and ordered a set. 10 degree bottom expected tonight. Very low for Arkansas. Should have ordered the first time. My hot rods would be snug as bug in a rug tonight.

I used the 1.5" polyiso boards for roofing wedged into my door panels. It had gray fiberglass Kraft backing and looks kind of tacky, but for $15 per 4x8' sheet and a good 20* difference in the summer, it's hard to beat. Got it at a local roofing supply house. 4 boards should cover an 18x7' door. For panels with windows like on my door, I used 3 sheets of the polyiso and 2 multiple thickness foam boards to go around and then over the windows. Mine were 1" and 1/2", respectively. Overall r-value is about r-8.

The foil face will help reflect the light back into the shop.

I also use a couple of small wedges through the manual lock to push the door tight against the frame of the garage. A simple cheap effective solution to help keep the heat in and cold out.

The door kits have a very low R value -- around 4 I think. However you can buy and cut the rigid insulation that has R 13, as some of these people did. Also, I suspect that the extra layer of radiant/silver, so it's on both sides, helps as well.

I'm finally getting ready to insulate mine -- so double checking --- you-all said to use thick foam tape to create an air pocket? So specifically how/where does the tape go please? Then how do you tape down the extra barrier of radiant, and HOW do you get it that NEAT! Wow!

Thanks

The only tape I used was the foil tape for heating and ac duct work to close up any gaps from cutting the ISO board.

Got my hinges today, put one set on the smaller door, these hinges are far and above much nicer and heavier pieces and wow what a difference. The air is no longer coming in around the that door, I will get the other set on tomorrow. It will be nice to have no more air leaks around those doors. Man am I glad I came across this thread.

Following for ideas...working on insulating my garage as well.

I did mine several years ago. I had a non insulated door. I bought foil faced 4 x 8 sheets, and cut them to fit sung in the pannels. Then I went over all the seams with foil tape. I then bought another big roll of tape and went over the whole thing. It really added some reflective value in the garage, as well as the insualtion factor. I figgured the cost when I did it, and I came in way lower than the kits or an insualted door.
