Hello
I've been searching around, but I'm a bit puzzled that I can't find anything on the subject. Someone else must have thought about this before.
70s house with insulation on the wrong side.
Slab->plastic->cellular plastic->fine concrete->floor
I don't have a single drawing, and the municipality has none in the archive either, so I can't answer how the slab is laid, what's underneath, etc.
The sills are right on the slab a bit below the floor, which means there are problems if you need to replace the drywall on the outer walls and main wall?
I started thinking about this as I'm considering additional external insulation, but if so, it would be best with plastic in the wall. 100mm insulation today and quite expensive heating. There's no insulation at all in the corners, so there's draught and cold floors by the walls.
I realize a 100% solution doesn't exist, but is there something that can be done to make it tight even if you can't reach the last 10-13cm?
I'm considering replacing the sills because of this and seeing if it's possible to cast up to floor level. The sills have 16% moisture. Directly against the concrete without sill insulation. Probably treated.
What I've seen looks fine though.
The conflict in me says it's reasonable to replace the sills before pouring a lot of money on new facade, bathroom, etc. What would you do in my situation?
