Why does everyone use OSB behind drywall?

That was a completely different description, delay yes, but how long we do not know...D Daniel 109 said:

You simply have to leave the doors behind you open when you flee the fire since according to you they do no good.
So the rest of us can close the doors.

If you find yourself in a situation where EVERYONE else has a different opinion, including several people who work with related issues, it might be time to have a little think. It could be that EVERYONE else is confused, but that's not the only possible explanation.Snoppenpåtoppen said:
All my interior doors are otherwise made of solid wood or steel. No, they are not gas-tight. Yes, they do prevent a lot of air exchange between the rooms they separate.
OK, but what is the answer to what started it all then?StoffeGbg said:
That is, someone thinks it was better with double plasterboard than single plasterboard on the walls in the kitchen, maybe just the wall where the stove is - it wasn't quite clear.
Is it good to put double plasterboard on a wall in the kitchen?
That will be a completely different googling 😁Mikael_L said:

To return to the main question, it seems a bit "unnecessary" to me to spend money on OSB or double drywall.
Fire safety might be slightly improved, but I believe more in having good smoke detectors and fire extinguishing equipment.
When it comes to hanging things, it takes a few extra minutes to use plugs instead of just nailing/screwing directly. If it's large and heavy items, you can usually find a stud or two to hang on if you want to be really sure.
So for me, the cost of OSB in an entire house seems too high in relation to the benefits it provides.

@Marlen Eskilsson - arguing was the worst justification of the century for removing my post, the thread currently consists of 99.5% OT arguing, if people had followed my suggestion instead of wasting time responding to pure nonsense it would have been much less arguing!mnils said:
But it's your site, if you want a digital kökkenmödding then go ahead, I can spend my time on other things! It's just a pity that you tolerate so much pure crap, it makes the sensible stuff drown and become impossible to find.
If you want a more stable wall and something to screw things into, chipboard is a much cheaper alternative to OSB.
I used OSB+simple gypsum throughout the house. Except for the bathroom where it was plywood+minerit (or maybe OSB+minerit, I don't quite remember, but there are pictures though). Then I have a storage room with just simple painted OSB.
I did it for several reasons, partly for easy mounting anywhere, and for example, a small brad that is then removed leaves barely any lasting mark. Partly for a stable and pleasant feel, and partly for (slightly) better soundproofing.
Several people mention that OSB has become very expensive today, I'm not sure. When I built, it was a noticeable, but not hefty, extra cost, so I accepted it. I considered and chose between OSB, plywood, tongue and groove, and gypsum. Tongue and groove was mostly ruled out due to unnecessary thickness, plywood because of the price, OSB and particle board were fairly similar in price at the time, and OSB somehow felt a bit simpler (and lighter panels).

More stable and you avoid Molly screws.😄bjolo360 said:
If you read the forum, it seems that basically everyone here puts up OSB boards behind the drywall in the walls and dismisses the catalog company's walls. Naturally, it feels a little more "solid" with OSB and I understand that it becomes easier to put up shelves. But when I think about my own current residence (simple drywall everywhere - built by a large construction company, of course), I still haven't suffered from it as far as I can recall.
Are there any more technical construction reasons for adding a layer of OSB? It feels like quite a lot of extra work and a large cost, which you would like to minimize when building a house. At the same time, you absolutely don't want it to feel like some kind of botched construction.

My house from Trivselhus (2008) has diffusion plastic in the outer walls just behind the simple drywall. I haven't made any holes in those walls 🙄
Well, some pictures in the living room are up with pins stuck at a 45-degree angle.....

A plasterboard 900 wide costs about 100kr and an OSB costs 219kr just for purchase..Mikael_L said:

Several mention that OSB has become very expensive today, I have no idea. When I built it was a noticeable, but not a bloody, additional cost, so I took it.
I considered and chose between OSB, plyfa, raw timber, and plasterboard.
Raw timber was mostly excluded for unnecessary thickness, plyfa for the price, OSB and chipboard were pretty similar in price then, and OSB somehow felt a bit simpler (and lighter panels).
I took the prices from ByggMax just to get a comparison😊
That's how it's been built since they started using plastic in the 60s-70s. As long as the screw remains, it's completely sealed. Removing the screw doesn't do anything since a 4 square millimeter hole has no impact whatsoever, unless for some weird reason you have a very strong overpressure in the house.Tomture61 said:
