I have removed all the floors on the ground floor of a terraced house because the insulation smelled. Everything is dry and fine except for the old removed nails set into the slab.
The walls are insulated with an air gap against the concrete and have stood this way for 55 years without any moisture or mold on the sill plates that are visible at least. I have opened up a few holes in the gypsum on the inside and the insulation is fine, as well as the hardboard that keeps insulation away from the concrete wall. The concrete is originally ventilated with PVC pipes about 1 m apart at the top of the wall from the outside.
Now they will soon install leveling floors and replace the impregnated sill plate on interior walls, so the question is whether it is worth rebuilding the exterior walls against the concrete or just letting it be since it has obviously worked for 55 years.
Otherwise, I should tear down all those walls and build up with metal and boards and skip insulation. It would then be cold until I drain and insulate with something like Isodrän in the future.
I have torn out all the floors on the bottom floor of a walk-out basement house as the insulation smelled. Everything is dry and fine except the old removed nailed studs that were pressed into the slab.
The walls are insulated with an air gap against the concrete and have been standing like that for 55 years without any moisture or mold on the visible studs at least. I have opened a few holes in the gypsum on the inside, and the insulation is fine, and so is the masonite board that keeps insulation away from the concrete wall. The concrete is ventilated originally with PVC pipes about 1 meter apart at the top of the wall from the outside.
Now they're soon going to install leveling floors and replace the impregnated sill plate on the interior walls, so the question is whether it's worth rebuilding the exterior walls against the concrete or just leave it since it has obviously worked for 55 years.
Otherwise, I will tear down all those walls and frame up with metal and boards and skip insulation. Then it will be cold before I drain and insulate with something like Isodrän in the future.
What would you do? [image]
I would leave it if it has worked until now. Isn't it unnecessary to replace what's not broken just because?
Yes, that's kind of how I feel. It gets harder to change walls after the floors are installed though. But I'll probably continue with the walls and sometime in the future, I'll have to cut them open and check.
