When I talked to a house builder about possibly having double drywall or OSB + drywall for soundproofing and durability for wall-mounted items, he mentioned fibergips. Has anyone here heard of it and has anything to add?
We chose the solution with osb+gypsum. Although it became more expensive than chipboard and double gypsum, damn what walls. You just drive in a screw and you can trust that it holds. Mounted the kitchen without further reinforcement, sits great. It will be the same solution when the upper floor is furnished.

Yes, I've looked into it.ylven said:
The cost of fibergips is slightly, slightly higher than that of drywall+OSB (at least in the quantities I looked at www.xella.dk). I was thinking of using it in the bathroom, but now I feel it's too much "new," there's a lot to think about already with all the pipes, drains, etc.
If I were rich, I would remodel our house and have plywood in the walls!perese said:the particle board is more porous and it doesn't hold as well. Perhaps the best is plywood ;D but they are even more expensive....if you don't want to install tongue-and-groove behind.
Now we have tree-tex, and it's NOT fun to drill into! :-/
;D there is usually a solid wall behind the trätex so you just need to use longer nails/screws
It's not harder than that to hang a picture
and it insulates better than chipboard or plaster
and it only applies to the outer walls.

The plywood is perfect as scaffolding.
I also usually use the plywood as flooring on the joists before the subfloor is installed. When it's time, you just raise the plywood against the wall and screw it in place. I don't trust either chipboard or OSB in this case, and plywood also dries well if it gets wet during the frame erection.

Danogips has a page where they describe various constructions and their soundproofing properties:

Regarding OSB. How do they work in wet areas?
I was thinking of double drywall, but many recommend replacing the inner one with OSB to avoid noggings, etc., for mixers, sinks, etc.
Opinions?

It works perfectly fine, of course. Where the OSB is placed, it should be dry; otherwise, you have big problems......SittinDuck said:
I eventually chose to put ply instead, just in the bathroom - it feels a bit sturdier. In all other rooms, it will be OSB.
You might also want to consider fibergips, search for Fermacell from Xella, and you'll find it. It costs about the same as OSB and gypsum together. At least as durable and more water-resistant.
Keep in mind that OSB is not completely dimensionally stable and should be installed with a few millimeters of space to allow for some movement. This is why the OSB board is three mm narrower than plywood, for example. Chipboard works excellently behind gypsum but not as well for removing and then screwing screws into the same hole. Formaldehyde is not something to mess with, but major suppliers like Byggelit and Orkla have reduced the amount to well below the legal limit. However, if you save a few bucks and buy cheap stuff at Byggmax, you never know for sure...
