Particle board or plywood behind drywall???

[Robin_Andersson]

Hi, I'm working on straightening the walls on the inside of the house and want something good to screw into behind the drywall...

What is the cheapest + best to put behind the drywall??? 10mm chipboard?, 12mm plywood?

Or is there something else that's good and cheap???
What is most common?

Grateful for answers

My standard response: Buy ply if you can afford it. Buy OSB if you want to save a few bucks per sheet. Forget about particle board. It's the worst option - it just crumbles when you really need it.

Your follow-up question is probably: "What is OSB?" Well, it's a coarse-fiber wood panel made through high pressure. I believe it stands for Oriented Strand Board. Whatever panel you choose, leave a gap of a millimeter or two. They CAN swell and cause trouble otherwise.

There are countless forum users who have placed the panels edge-to-edge and never had any problems. I'm one of them, but do it right from the start so you at least avoid the risk of cracks.

Exactly - "aaaaaldrig".

I would also use plyfa if I could afford it, especially since 12mm plyfa is much lighter than an OSB board.

ok thanks for the quick responses... I think I'll buy a bunch of 12mm plywood boards from Byggmax.. it's not so expensive there... And as you say, it's annoying if you have to screw something up and the chipboard just crumbles....


Thanks ..

If you are using high-quality particle boards, like Byggelit, THEY MUST be glued both to the wooden studs and at the short joints. The boards MUST be installed tightly against each other, except in the internal corners where a few millimeters should be left.
If the boards are glued, they have "nowhere to go."

OSB has the measurement of 1197mm for c/c 600 studs. That clearly explains that a gap should be left at EVERY joint.

If one absolutely needs straight walls (not springy or unstable), what should be behind the plasterboard? Particle board, plywood, or OSB? And what thickness? Without overdoing it! Have cc30.

Will have large tiles on the walls...

 

[Fasting65]

Butcher: It will likely be stiff regardless of solution (chipboard, plywood, gypsum) if you have cc300 mm.

However, if you want insanely straight walls, go with metal studs instead of wood.

If, however, you want insanely straight walls, use metal studs instead of wood.

;D ;D

 

[Butcher]

use metal studs instead of wood.

It's all over with metal studs because I have wood. But isn't there anything that is better or worse then?

 

[ByggaNytt]

Yes, if you want an answer, it's clear that you should have plywood of the same thickness.

However, it works just as well with OSB 11mm + gypsum, which, by the way, coincides with my choice

How does råspont compare to sheet material in terms of cost, as it's easy to install anyway.

 

[Fasting65]

Byggmax charges 3.99 for 1lm of raw lumber 17 mm thick. It is 95 mm wide. So it takes about 10 linear meters... say 11 linear meters for 1 m2.

Exactly - "neeeever".

I would also go for plyfa if I could afford it, mainly because 12mm plyfa is much lighter than an OSB board.

Much lighter? Percentage-wise or in grams?

Jag skulle också köra plyfa om jag hade råd, framförallt för att 12mm plyfa är mycket lättare än en OSBskiva.

I don't really know, but when I'm carrying an OSB myself there's a lot of puffing and grunting, a plyfa doesn't cause nearly the same effort.

 

[Fasting65]

I think OSB is quite okay to carry. 120-gipsskivor are a bit more troublesome - especially since they are more fragile.
