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?

Pictures from before and after the bedroom was completed. Only the remaining parts of the house are left...
 
  • A bedroom with a white dresser against a beige wall, adorned with vintage racing posters and decorative items on top.
  • Renovated bedroom with a neatly made bed, wooden floor, and an open closet with sliding doors displaying clothes on hangers. Simple and modern decor.
  • Removed fiberboard wall panels and insulation debris on the floor, with ear protection gear on top, in a room with radiator and patterned wallpaper.
  • Empty room under renovation, exposing wooden wall studs and partial insulation removal. Tools and clothing on plywood floor, overhead light illuminating space.
