That may be true, but it builds the same, so it doesn't matter. Personally, I don't use OSB, I prefer plywood.
We're drifting off-topic now, but this is still a bit interesting. We ourselves used OSB + plasterboard for most of the kitchen, and it works great! Why choose plywood, which is at least twice as expensive? I know the difference between the boards, but I don't really see the benefit as wall material, unless it's going on a surface where you're going to paint it, which is often not the case.

Moreover, TS should, of course, ask all these questions to the carpenter.

OSB works. Plus, it contains more crap than the plywood. That's one of the reasons.
It's not uncommon for larger clients to often prescribe plywood in projects as it has somewhat better properties than OSB and often has a higher environmental rating and traceability in content.

Both consist of wood and glue, and the load-bearing capacity doesn't seem to differ by more than a few kg when it comes to fastening with screws or anchors? OSB should be much more environmentally friendly considering it doesn't require whole fine wood panels?

What is the "stuff" being referred to? Something that would become hazardous to health when it's behind drywall?

Plywood has its advantages; it's perfect if you need a nice surface, but that's not needed behind drywall.

Plywood certainly has its advantages, it's perfect if you need a fine surface but it's not needed behind drywall.
I think it depends on the fact that OSB historically has significantly more binding materials in the form of glues and formaldehyde. Then plywood is more form-stable over time. OSB is poor man's plywood. The expression Ryssplyfa is what OSB went under. There is a difference in working with the different sheets. I claim that the K-ply has no higher requirements for surface finish. I choose plywood 8 days a week over OSB. It's not cost-driving in the choice either, I would say.

There is a difference in the materials and I probably have some preconceived notions since I disliked working with OSB. Then, as I said, it's no coincidence that many property owners would rather pay extra for plywood.

Why don't you ask your craftsman? He knows exactly what's needed.

- Measurements?
- Frame (thickness)?
- Threshold?

The craftsman is likely responsible for assembly details like fastening, radiators, etc.

When it comes to the design of the door, you typically buy one in the same style as the rest of the house, but of course, it's entirely up to you to decide. You also need to consider if you want a soundproof door, a filled door, a solid door, or just a cardboard door. How do you know? You go to the store or browse the manufacturers' websites.

Don't forget the handle, preferably something similar to the rest of the house.
Agree, a soundproof door is preferable.

Absolutely, there is a difference but behind drywall, I still don't see any functional reason to spend on plywood over OSB. I prefer oak, but that doesn't mean I put oak studs in the walls.

The advantage I might see is that plywood has a denser surface, so perhaps it is better at stopping sound waves, but probably there's a marginal difference when drywall and insulation are installed.

Are you aware of any actual functional advantage of plywood over OSB besides it having slightly higher load-bearing capacity? And of course, that you prefer working with them.

Soundproofing is nice, but it requires not only a filled/solid door, it must also be airtight. If you can achieve that, the difference is enormous! However, you need to consider the ventilation. If the house has exhaust air or natural ventilation, the doors usually have ventilated thresholds, and this is not compatible with soundproofing. Possibly, you can work around this if you have, for example, an FTX system for all rooms, or you settle for just a bit of soundproofing. If nothing else, a filled/solid door gives a completely different feel.

Always a smooth door. Otherwise, you'll regret it later when you have to clean and stand there wiping a bunch of grooves. Same with cabinet doors, smooth.

Doors are usually easy to clean, no narrow and sharp grooves that can be found on, for example, kitchen cabinet doors.

Plywood absolutely has its advantages, it's perfect if you need a fine surface, but it's not needed behind drywall.
Comparing osb/plywood to pine/oak is quite skewed. But anyway. OSB contains more formaldehyde and, in some cases, isocyanate adhesives. They are also often imported. Today it is important to minimize environmental impact in the building process as well as ensuring a good working environment for professionals.
Functionally, it is form stability and plywood is slightly better in tensile strength. However, it is rare that you need to hang tanks on the wall. Then plywood can be used as burglary protection in certain constructions. I also don't know if osb can be used in fire-rated walls; plywood, however, can.
OSB costs 100 bucks per square meter, give or take plywood 150 roughly. A wall costs about 900 bucks per square meter with double drywall. If you do OSB, you land at 1000, and plywood at 1200.
The time accounts for 800 bucks. The point is that it's not a cost-driving choice.

Always a flat door. You'll regret it later when you have to clean and wipe a lot of grooves. Same with cabinet doors, flat.
I replaced all the doors in the house with 3-panel doors, and I can't say the cleaning became more extensive, but we generally keep the house quite clean. If dust were to gather, it would be on the horizontal grooves (6 of them), which are easy to clean with a vacuum or duster. I can only recall doing it once in 3-4 years on a couple of the doors.

When it comes to kitchen cabinet doors, we chose flat ones since they get messier, and it's really nice to be able to wipe them quickly and easily. Unfortunately, we chose Höganäs Biselado tiles, which aren't flat, it would have been clearly easier with flat ones here too, but it's doable with a bit of extra effort.

Of course, this is a highly personal preference, but in our house, we prefer flat surfaces where it gets messy, like the kitchen; otherwise, appearance comes first.

Osb costs 100 kronor per square meter give or take, plywood approximately 150. A wall costs about 900 kronor per square meter with double gypsum. If you use osb, you end up at 1000 and plywood 1200. The labor accounts for 800 kronor. The point is that it's not a cost-driving choice
When I look at our local Hornbach, the cheapest OSB costs 270 SEK (11x1197x2500mm), the cheapest plywood costs 399 SEK (12x1200x2500).

So a room that is 12 x 6 m (5+5+10+10 panels) costs
OSB: 8,100 SEK
Plywood: 11,970 SEK
That's almost 50% more expensive, does it look correct?

You mentioned the environmental aspect, so today's OSB still contains harmful waste (even the ECO version?)? Surely OSB must be much easier for nature to produce? It doesn't require perfect wooden panels?

If dust collects, it would be on the horizontal tracks (6 of them), and they are easy to take with a vacuum cleaner or duster. However, I can only remember doing that about once in 3-4 years on a couple of the doors.

When it comes to cabinet doors in the kitchen, we chose smooth ones because there's more smudging here, really nice to be able to wipe them down quickly and easily. Unfortunately, we chose Höganäs Biselado tiles, which are not smooth; it would have been much easier with smooth ones here too, but it works with a bit of extra work.

This is obviously a highly personal preference, but in our house, we prefer smooth surfaces where there's a lot of smudging, like the kitchen, while appearance takes precedence in other areas.
Can't vacuum up moist dust like in the bathroom. In my house, I have old doors with lots of tight grooves. Luckily, I have poor eyesight and don't use glasses/lenses :crysmile:

Aha, we probably never have it that humid in the bathroom. However, I have seen acquaintances who have mirrored doors in the toilet and have gotten moisture damage so that the paint has peeled just where you might think dust would settle, so I can absolutely see that it can be a problem. I would guess that their bathroom ventilation is inadequate, or ours is extremely efficient.

With so much else, you have to go with what suits you personally in terms of function and appearance. Even if you generally shouldn't mix different designs, it is naturally possible to do so; sometimes function is more important.

4000 is money, of course. It's not much in a room of 96 square meters or then 60 cubic meters of wall surface with an additional cost of 70 per square meter. But that's how I think.

I actually checked out the glues and today OSB is significantly better than it used to be. That's good. Then OSB has the plus side of using residual material, which is good. It takes more energy to produce it as I understood it.

Quality-wise, plywood was better in terms of moisture and it has 2-4 times better bending strength.
It also differed depending on whether you had class 1, 2, 3, or 4 on the OSB; 2 seems to be normal OSB.

If I could choose, I would go for tongue and groove 600 plywood, but it is even more expensive and is good for sheet metal frame constructions and when you're using large amounts. Not something for a home tinkerer to mess with since you don't consider labor costs.
