We have bought a new house. Built in the 50s with a brick facade. Attached cold garage from the 60s. On the wall towards the house, you can see bricks, so the garage roof is probably anchored to the brick in some way.
Now I want to have heat in the garage. The question is what to do with the brick wall. Should I frame up against the brick wall, with insulation and gypsum to avoid a thermal bridge?
The garage roof today is a flat roof with some leakage. I plan to replace it with a roof with a slight slope backward. I'm considering how and to what extent I should anchor it to the house. I assume you have to mill a groove in the brick to insert a sheet metal flashing at the junction between the roof and the brick wall.
Should I consider the garage building as a self-supporting structure built with studs that carry the roof, with just a few attachment points to the brick wall so that the buildings don't separate? Or should more use be made of the brick wall? (as seems to be the case today)
The slab is probably uninsulated. That was common in the 60s. Not much to be done about that. But I considered at least digging around the slab and putting isodrän panels against it. This would both drain and provide some insulation, I think. Any thoughts on this?
