Why does everyone use OSB behind drywall?

[FredrikR]

Hole-in-ones work poorly in osb and with Essve's osb-screw the board doesn't pull into the metal stud unless you managed to get it tight against it beforehand because for some inexplicable reason it is fully threaded.

If there's anything I regret, it's that I used osb in the kitchen instead of plywood. Putting up things in old single drywall is awful.

I used HoleInOne when I built the garage, with OSB behind all the drywall. I think they worked as intended, or maybe I unconsciously compensated a little on the height.

Then you were probably better than me at compensating. The problem with osb is that the hole saw cannot fine-tune its position when the center drill finds the receiver because neither the hole saw nor the drill can move laterally in the OSB.

Then you were probably better than I at compensating. The problem with osb is that the hole saw can't finely adjust its position when the center bit finds the receiver, because neither the hole saw nor the bit can move laterally in the osb.

I haven't encountered that, but I also haven't built many walls in my life. But I would say that "jiggling" a bit with the drill is enough to slide the hole in...
Sorry, there were many innuendos, but hopefully, it's obvious what I mean on a serious level..

With double layers of OSB glued and screwed together, the walls become so rigid that you can install sliding doors in them without adding much thickness. Thus, you save space. This is my own construction idea that I had to persuade (persuade for a long time) the carpenters to try when I remodeled at home, but it works great. Extremely stable. Much more stable than the adjacent wall, which is gypsum and single OSB but with studs behind.

A slick solution when you want to install sliding doors in existing walls. I have two instances where regular doors didn’t fit. If I ever build a new house from scratch in the future, there will be many such doors...

Or like when an acquaintance tripped over their dog and fell into the wall.
When then 130kg landed against the wall, it made a decent hole..

Fritjof Nilsson Piraten could have written a decent short story about that!
If not a novel...

It cost me 20,000 to make choices, etc., for 200 square meters. Definitely feels like well-invested money considering the advantages.

An acquaintance backed his American car in the garage with the door open, and of course, the door edge hit a seam on the wall into the hallway, causing the car door to swing open. It knocked over a dresser there with a lot of things in and on it. The wife wasn't too happy. I'm currently building a 370 sqm garage, and it will have OSB everywhere behind the drywall. I'm about to send out quotes for OSB now, might as well buy at least two pallets at once.

Two pallets won't be enough for 370 sqm...

 

[Daniel 109]

Why not? It will be 77m all around if it's square. A pallet is 60 skivor. Two pallets of skivor are more than enough.

 

[Anders & Ming]

The garage is 22 m x 9 m and has 3.5 high walls + an upper floor that will eventually be completed.

 

[Anders & Ming]

a question chipboard vs OSB which is stronger? The chipboard costs 73 kr and OSB 128 kr

 

[Rabbithole]

I would guess that OSB is stronger if it's one of those soft particle boards.

 

[Anders & Ming]

the chipboard Bauhaus has 11 mm don't know if it is soft

 

[gusvo085]

Osb!
Spån is difficult to attach things to in comparison with osb.

 

[Rabbithole]

Checked Bauhaus and saw a 10mm chipboard. If so, it's floor chipboard and not very stable. Go with OSB and it will be fine.
