577: INSULATED HANGAR DOOR

1

I purchased a home with one of your doors this summer, with winter setting in, I see the lack of insulation is likely to be an issue with the way I use the space. Considering the basic materials for the hard bord and blankets, do you have basic diagrams for cutting and fitting these materials? I am considering both as the light coming through the door in the summer is nice but would require the blankets?
