    insulated garage doors question

    Does anyone have insulated garage doors? So far the best quote has been for Amarr (R19) and am wondering how useful it is? I read a previous post about heating a garage and looks like the first step is get everything insulated first.

    My previous house had uninsulated and I cut pieces of insulation to fill the panels but in my opinion was pretty useless as I could feel the cold radiating off the bare metal at the joints.

    For this winter I plan to just use a 220v heater and may look into a minisplit or something next year.

    Re: insulated garage doors question

    Steve. I used "insulfoam" from Lowes to insulate my garage door. I believe it took two packages to complete my double-wide door.

    https://www.lowes.com/pd/Insulfoam-C...ation/50244957

    It doesn't do much for the joints -we are talking about aluminum doors and that metal has an almost zero insulation factor - so there is not much you can do about the chill from the joints.

    Re: insulated garage doors question

    You can get some of the (very) thin foam strip (single-side sticky) to place between the panels. You would have to fill in between the panels as the door is raised and makes the turn at the top. This should break some of the airflow, but as Raymond says will not change the actual thermal dynamics of the aluminum doors.

    Re: insulated garage doors question

    We moved into our house last year with an uninsulated double-wide door. When the sun beat on it you couldn't touch it and the inside garage temperature went above 85F in the summer. I bought the pink insulation made for garage doors from Home Depot. The insulation is faced with a white vinyl. It's easy to install and the temperature never rose above 72 this summer. One thing it does do is add weight. A lot of weight. And the little plastic clips don't stay glued to the door unless you get some heavy duty adhesive. On our last house we had an Amarr insulated door. What I liked about it compared to the do-it-yourself door I have now is the finish on the inside. The aluminum panels look very nice compared to the vinyl of the pink insulation. When the current one craps out I'll be going with Amarr again. I can't say it about all doors but on newer ones each panel has a fold over the gap between panels that blocks the wind. It's not perfect but keeps most out and on mine you can't see light coming through.

    Re: insulated garage doors question

    we were lucky enough to get the doors with the built in insulation (aluminum siding on both sides) when we brought the house. It does make a huge improvement when the door is down (100 outside, 75-80 inside).

    Re: insulated garage doors question

    The insulated doors are well constructed and a better solution that actually work instead of the DIY BORG panels.

    Re: insulated garage doors question

    I mainly insulated my garage doors against the cold, as the doors face to the North-West and only one corner gets any sunlight. Yes, I have noticed an improvement since I finished insulating both the garage walls and the doors. Without heat recently, when the temps were in the high 30's and low 40's outside, the temperature inside was 48 degrees. With help from an oil-filled space heater in two hours it was close to 60 degrees and I could work comfortably.

    Re: insulated garage doors question

    I found the insulated doors made a noticeable difference. I have a thermal camera and the door area temperature differential proved satisfactory in cold weather. I forget the exact temperature numbers. The weak spot in our install was the side weatherstripping. It was hard to keep this seal from leaking air over time. Given the linear feet of 2 garage door sides, these air leaks can add up. Maybe there is a product that air seals the sides better.

    Re: insulated garage doors question

    I think all garage doors these days are steel. I assumed they were aluminum too and everyone so far has quoted steel doors. One of the guys giving me an estimate said they don't even bother selling the steel to the scrapyards anymore as its not worth it to them.

    Re: insulated garage doors question

    I added the Owens Corning insulation to my garage doors when I had my shop in the garage. It did make a difference, but the installation left a lot to be desired. The clips that held the insulation in place kept coming off and/or breaking. In the end, and after moving out of the garage into my current shop, I took the insulation off the doors and trashed it.

    If I had it to do again, I would replace the garage doors with insulated doors. More expensive, but worth it in the long run.
    I know you believe you understand what you think I said, but I am not sure you realize that what you heard is not what I meant.

    Re: insulated garage doors question

    Built my shop in 1981, with insulated steel doors. Never a regret. Keep shop around 56 degrees all winter long, except on days like today where outside air was 70 degrees, and shop temp rose to 68.

    Re: insulated garage doors question

    I replaced my wood fiber panel door with a thick insulated one with steel on both sides about 10 years ago and couldn't believe how much it helped. It was about a 20F improvement in both summer and winter. Winters went from nearly freezing to 55F and easily warmed with a kerosene heater for an hour. Summer went from 90F to easily comfortable with a window AC unit started about 10am.

    One subtle improvement with a new door was also better gasketing at the bottom and around the side and top edges. Insulation is important, but air sealing also contributes.

    Re: insulated garage doors question

    I cheated and bought my doors already insulated. I did have to redo the jamb and sill to stop the airflow though.

    Re: insulated garage doors question

    I've been given a soft quote of about $2100 to replace my garage doors and openers. Doing it myself is not an option.
