OSB or plywood behind drywall?

[Johan Gunverth]

why didn't they use glue-free raw planks in their own houses?

They are lazy.
I also believe they skipped the glue on the exterior walls, so that's probably correct.

Didn't they put chipboards on the outer walls? Only the inner walls

Hehe...the inside of the outer wall. Yes, but they didn't seem to glue the boards to these particular wooden studs. Most likely because they are lazy bastards.

I didn't think they glued the chipboards but that they contain glue when I wrote glue-free råspont

Beijer Bygg's accounting is (just like before) a bit "interesting" considering that they use chipboards measuring 1198mm to be able to maintain 1200c/c with a 2mm gap, as a requirement. Where can one get these boards with that odd measurement? Why does the manufacturer ByggElit state in their installation instructions that the (1200-)boards MUST be placed flush against each other and that one should glue the short joints? Are these even chipboards for wall mounting that Beijer is writing about?

The figures come from SP's test, and it is Byggelit that ordered the testing from SP.

Well, now there are assemblers on the house teams and then there are real carpenters.
Never take advice from someone like that if you're going to build a quality house.
OSB as a floor??? Well, you'll get a floor that's soft to walk on.

back to the question. osb because it is cheaper

Sure, now there are assemblers on the houseboats and then there are real carpenters.
Never take advice from one of those if you want a quality house.
OSB as flooring??? Well, you'll have a floor that's soft to walk on

All carpenters are recognized as skilled. Have been in the industry for at least 20 years. The house manufacturer is a locally recognized high-quality contractor. Do you want to continue arguing?

As a temporary floor during construction. Floor protection or between floor joists while the house is being assembled. Then the junk is thrown away.

back to the question. osb because it is cheaper

råspont because it seems best and also contains no glue

In fact, none of the aforementioned materials are needed to make the wall strong and/or soundproof....metal studs and double plasterboard will make it both quiet, straight and without any potential creaks....

Okay then. Raw wood goes fine. Just takes a bit longer.
But something behind actually provides better anchor points.

Ah! It's the Stabil boards and not the regular wall board. I felt these and they felt more like OSB, a bit flimsy. More expensive too. The question is if they aren't made with the same kind of glue as OSB. Couldn't be glued either. The regular wall boards are harder too.

 

[SBH]

Particle board moves. All wood moves.
Then pre-drill in the boards during installation?? Users of the wall won't think about it.
And it's a disruptive element when installing cabinets, stairs, hall furnishings, etc.

Absolutely best is råspånt, followed by OSB and then chipboard, lastly double drywall and something that should be forbidden, single drywall

Has anyone found use for their various materials behind the plaster? I mean do you hang a lot on the walls? Except in the kitchen and bathroom of course. Is it worth the work or wouldn't it have been just as good with double plasterboard?
