OSB or tongue and groove?

[Honey-Bunny]

Does anyone know what is best to put in the inner walls behind the plasterboard, OSB or råspont???

Please motivate your answer so I can get some more "meat on the bones"!

Raw wood sheathing, you get a few extra mm to screw into. Normally, you use 12 mm OSB/plywood but the raw wood sheathing is usually around 17 mm

Disadvantage, it takes longer to put up

Advantage, you can buy a nail gun with a clear conscience

I personally use raw wood sheathing and it's actually quite quick to put up. It's also easy to handle

12 mm OSB since it is easy to transport + cheap at byggmax...

have plyfa in, for example, kitchen and bathroom where I want it to have more grip if you screw up something heavy...

Price or transport does not matter, as the housing company is responsible for that. Raw board is in the contract, but the builders want to change to OSB, I assume because it's more difficult to install the raw board.

So aside from price and transport, which is the best to choose????

 

[tiggre]

råspont if it doesn't cost you more

Tongue and groove is better if you can get it installed and finished for the same price. The difference is minimal, but it does give a slightly more solid feel with tongue and groove. (I'm personally using OSB in my project to save some time (=money)). The carpenter who's helping me with the extension used tongue and groove in his own house... ("if the carpenter gets to choose").

I put up OSB. I think it's a great thing - stiff and sturdy. Unfortunately, it's quite expensive compared to raw planks, but much easier to put up.

Despite everything, raw pine boards are more solid than OSB.
Additionally, you have a pure material, without glue and other chemicals that are inhaled by the inhabitants.

That's right - otherwise, I would never have used it.
From what I understand, there is only a minimal amount of resin as a binder, then they press the stuff together with enormous pressure.

Keep in mind that OSB + gypsum almost gives the same fire rating as 2x gypsum. Glue is what is used to hold the board together. The lignin, which is wood's own binding agent, does not work under high pressure because it dissolves under moisture stress. Is there not some value in the fact that the OSB is dimensionally stable and has a positive impact against tension?

Does anyone have any experience using 9mm board behind the drywall?
I have it on the ground floor of an Eksjöhus Kvadraten, but only on the outer walls.
So I'm considering having it on the upper floor in the slanted ceiling and on the gables.
What do you think?

I want to recess the boards between the studs to optimize the living space - is this being foolishly cheap???

Not cheap, but maybe a little foolish. I don't think your room space will really suffer if the room becomes 22mm shorter/wider. However, it will be quite cumbersome to install the inner studs for the boards.
OSB, by the way, is good for both screwing and nailing into.

I probably realized that I was a bit off track. I'm making it easy for myself and just slap everything on the outside!

Good thinking, the cycling season is over! ;D

Kroonospan's OSB contains about 6% mups or is it mupf glue.

Save the forest and use OSB made from by-products.
