The wall is 36.4cm (14.3 inches) thick plus plaster on both sides.
The brick material is hard to identify; they are gray, and when broken, they resemble something like black gravel (approximately).
The effort involved should be kept reasonably low. This means I don’t want to have to remove old plaster and similar layers first. It should be possible to apply insulation more or less directly onto the existing surface.
The insulation material should improve soundproofing or at least not worsen it.
As a new exterior finish, a wooden facade is planned. I’m not yet sure exactly how or what type, but it will definitely be wood and not plaster. Of course, it will be treated with an appropriate coating.
The wall receives occasional strong vibrations (east side), while the west side is the weather-exposed side.
Therefore, moisture should be able to escape well again.
How thick should the exterior insulation be? Is 5cm (2 inches) of insulation sufficient, a minimum, or rather the upper limit for a reasonable cost-benefit ratio?
The insulation effect should definitely be noticeable and not just theoretical.
I don’t want to spend a fortune, but since the total area to insulate is not very large, it could be somewhat more expensive if it is really worth it.
The area to be insulated is about 30 square meters (approximately 320 square feet).
Is it still possible to carry out the work before winter, say by mid-November?
Must the weather be completely dry on the day(s) of installation?
Of course, I would not want to install anything if the wall is wet.
