Hello,
I have a Hultsfred house from 1965 with a brick facade. All the inner walls consist of fiberboard. The insulation between the 30 cm wide studs is something that resembles slightly softer masonite. This smells a bit stale, probably due to the binder. I'm in the process of removing all the insulation to replace it with non-smelling material.
The insulation is glued on either side of the stud in three layers. I'm using a multi-tool with a half-moon for metal/wood from Bosch, which I have found to be the best. I have to cut both sides before the insulation can be removed. Then I scrape the studs by hand. When this is done, the wood smells fresh.
There are also many nails that need to be cut. I've tried an angle grinder with a metal disc, which works fairly well. A reciprocating saw has also been tried. Good if you want to cut away a wall, less good when the studs need to be preserved.
Question: Has anyone done this job throughout the whole house and come up with a better way to remove the insulation?! Maybe there's a cutting disc for the angle grinder that's good for this job?
