Hello,
We have a Borohus built in 1988 where we have developed a minor moisture damage in the ceiling on the upper floor. In connection with this, we need to replace parts of the ceiling. The ceiling is built with a type of panels nailed directly to the rafters, with CC 120. They are 2400x600mm, and 22mm thick. They consist of a wooden frame with tongue and groove, covered with thin masonite-like boards on the top and bottom. In the space between the boards, there is a paper-like material in a corrugated construction, similar to the inside of a lightweight interior door. They are sturdy enough that the ceiling is rigid despite the sparse joists.
When I look in the materials list from the construction, they are listed as "SB-INNERTAKELEM 22x615x2415 GRUNDM". No manufacturer or similar is mentioned.
I haven't been able to find these or similar panels at any retailer. Does anyone know more about these panels and if there is anything currently available that can replace them?
