A good number of mugs just like me on here who spent extra to get an insulated roller shutter door rather than an uninsulated roller shutter door.
The foam insulation is too thin to insulate to any extent as if it was, the size of roller when loaded with the door would not fit between the top of the door opening and the garage roof.
They are just as bad as a single glazed window, insulation wise and while my garage has insulated walls 4" to 6" and ceilings again 4" to 6", on a cold day when I'm working inside the garage with electric fan heaters on, the inside of the roller doors are covered in condensation.
To get a properly insulated door you require to install a sectional garage door and in that case you have to have somewhere for the door to go when open and if that is the roof and you want a lift in the garage you loose lifting height as the mechanism will get in the way!
Therefore what do you want to do in the garage. Do you want it basically to not look as bad as it is or do you want to spend time in there maintaining the car and doing other odd jobs in the winter.
If you want to spend time in there in the winter we have to talk insulation, heating and lighting and sufficient power or if it is just to look less worse, then painting the walls and either painting the floor or some form of floor covering is all that is required.
