Sectional Garage Door Insulation

[porschedude996TT]

Hello,

Anyone insulate a sectional garage door. My first concept was to fill the u-shaped void with expanding foam and then carve it flush with the inside flange and then cap it with a sheet of thin aluminum. Problem is the top section of the door has windows and short of building an aluminum frame around the window and it would start to look like a camper shell or an airplane...or a brick Sh17-House...

It would be wonderfull if someone made an insulation kit that I could easliy install.

Any suggestions?

I've seen 2" poly foam insulation kits for them somewhere... Just finish cut & Glue.

Homie depot and lowes both sell insulation either in 4X8 sheets you can cut and install yourself or in already cut . I would do one of those options with a spray glue on the door then metal taping the outside edges . I will tell you it would take ALOT of the spray foam to pull it off tried it once went through 2 cans nd didnt even have one setion of the door filled mind you my door has 18 seperate cavities so thats 3 cans X 18 at $4-$5 bucks a can . The sheets of foam are between $20 and $30 bucks a sheet in 4X8 sheets.

It may be better to get a new door. Some insulated doors have some sort of thermal break at the edges and joints. Otherwise the metal rim of the panel conducts energy to and from the garage.

Thanks guys, I was trying to get off cheap and clean. I checked into some spray foam that I could use as a filler and then skin the inside after I carved the foam flat. The foam is about $200 and I have two sheets of thin textured Aluminum to do one door (8'W x 7'H) and would need another two sheets to do the second door (12'W x 7'H). Thats going to kick up the cost...

Torgue1st - You bring a good point with the Thermal Break. I have several man-doors that are steel skinned and wood framed and the steel wraps around and into a groove at the edge and the two skins never touch.

I had a sectional door installed in my last house and it was a Clopay Insulated and it had a single wrap that formed the complete cross section and a seam at the bottom. It was injected full with ueathane foam and was ridgeid as he77 and quiet and the inside as I recall was not as cold as the outside. Maybe the total cross section of thermal conductive material was small...

A thing to consider also is how much weight you will be adding to the door even when using foam and a thin aluminum sheeting to cover the insulation. I used the Insul-Foam kits with the plastic sheeting bonded to the foam and it was a noticable increase in weight. Not a real problem as I don't have a gararge door opener or need one for my shop. I would have adjusted the springs but they already look as if they are pretty tight.
