I'm working on a garage from Lundqvist trävaruhus.
The door opening is 5200 wide and I have a HEB220 steel beam above it. After installing the door and starting to insulate, I've realized that the beam will create a significant thermal bridge.
The garage will be heated and it will be cold outside during winter.
*The beam rests directly on the end grain of three studs at each end.
*The wall plate lies directly on the beam.
*To mount the garage door, I put up 20mm plywood that also lies directly against the beam. Since the door's tracks and motor mount are attached there, I can't cover it with vapor-tight plastic without taking down the entire door (which I'm unsure I can reinstall without various new parts).
Now to the questions:
1. Is this a big problem? What can it lead to?
2. What solutions do you see? Tear it down and redo or is there something that can be done at this stage? For example, insulating externally and building a roof over the door?
