    I want to insulate the inside of a wide (double) garage door at my Dad's house. It has a roll of glass in it but that is already cover with aluminum foil so visible is not an issue. What is best? I was thinking of using duct board and cutting it to fit in the different sections. How does that sound? Or is there something I could get at Lowes that would be better? Thanks in advance for all the great advice you provide on this web site.

    P.S.: The door will still have to open and close.

    We used styrofoam on the door at the shop. You may have to have the spring adjusted to compensate for the extra weight.

    Thank you sline-dawg for the spring tip. I would not have thought of that.

    Ductboard will be the most expensive and not right for the job. I'll go to Lowes and check out the r value and weight of what they have. Operator, I'm not sure what blue insulating foam is, but I'll ask. I want to use something that is hard like ductboard or styrofoam. Thanks all.

    FYI

    A little off the subject but ...

    I called the people that sell the bubble wrap and they are telling me that the OSB roof decking with the silver radient barrier is not perferated. Therefore it will trap moisture in the OSB wood and rot it out prematurely

    Also metal roofs & garage doors are only about 50% reflective so the foil is still needed in that application.

    Use that "foam in a can"

    and spray it on. I'd use blue foam too. Much denser [stronger] than white.
