Superinsulated garage doors — again
I know garage doors have been debated quite alot already,
but i haven’t found any mention of anybody trying to actually “add ” insulation to an existing door
I was looking at residential and commercial garage door manufacturers website a few moments ago, amazed on how “their special” polyurethane achieve R16 at only 1.75″
( they must be onto something we do not know!! )
And i notice the lack of new solutions for cold climate situation other than
the 2″ thick steel/poly/steel slabs they advertise as R18 , which is probably closer to R8-R10.
And then, i though about something i did in the past…
we modified an older steel type door by gluing aluminum composite panels ( ACP )
which are prepainted in kynar, to the exterior of the door..
ok it was 3mm thick and we only had to move the weather seals a bit..but it was very easily done,
since the door joints ” open up” on the exterior side.
So, why aren’t we already laminating insulation boards on the exterior of all our garage doors?
Anyone done it yet ??? i don’t believe it would be very hard to glue or fasten a rigid XPS or very dense EPS 2″ board at the exterior side …
The only thing required to be modified is the length of the legs holding the roller tracks to the wall
( and maybe the header spring distance to wall ?? )
What do you think ?
I have many projects to come in the following years , all of which will feature one or several garage doors … would be delighted to be able to use the “cheap” regular 1.75″ doors and only have to add insulation boards and a new finish of my choice on top of it ! 🙂
