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 ! :)
