I am going to build a "temporary" wall, meaning it will be in place for about 15 years and withstand a teenager on each side. The idea is metal studs against the ceiling and floor with standing wood studs, as well as insulation of course. But then what? I'm not keen on OSB-gypsum-mud-sand-mud-sand-mud-sand-paint-glue-wallpaper, so I'm looking into ready-made solutions.

Would panel boards with a 10-13 mm MDF core hold as the only layer on the wall studs, or would it be too weak? I've never had teenagers, but I can imagine they are hard on the house...
 
In my house, there's some form of masonite board, 10-12mm thick, it's been there since the house was built in 1970-71, so I think the answer is yes...
 
Same here, I would say it's 8-10 mm even... In my case, they are glued with some brownish-black glue along the entire length of the rule. Stuck like h-ll...
 
I'm not entirely sure about the thickness right now, but it's definitely not as thick as a plasterboard.
Mine are just nailed and not glued, and they hold well.

It holds, you could probably even go down to 6mm without a problem, but it will be difficult to hang things on the wall then...
 
Yes, if you're building with studs, they are what hold up the wall. MDF is probably much more stable than drywall even.

MDF really has only four drawbacks:

1. It's extremely tough to saw through – power tools are required in my opinion.
2. If you don't pre-drill before screwing into it, it will crack. Thinner screws also tend to pop out easily.
3. It can't handle any moisture. Should be kept as far away from wet rooms as possible.
4. It absorbs a lot of paint when painting. You'll need good quality paint and expect a couple of coats.

Otherwise, I've built a thing or two in MDF and definitely think it has its place. It's hard, heavy, and stable if used correctly. You get a smooth surface right away and it dampens sound reasonably well. So your idea isn't stupid at all and you can even reduce the thickness unless you want to soundproof between the teenagers, of course. Which might be needed...

ps. I also recommend gluing them to the studs instead of trying to screw them in. It ends up looking infinitely better and is more effective.
 
Hmmm, I hadn't thought about soundproofing. I probably need to add a layer of plasterboard as well...
 
Is it really that much more work to go for insulation, OSB, and drywall? 15 years is a long time.
 
Is it a wall or just a room divider?
 
Umm uh what's the difference? I'm going to divide a room in two with a wall. I want a solid wall so both children can have some privacy. But I'm eternally tired of plastering and painting now, so I'm looking at ready-made solutions.
The room is built specifically for this purpose, so I have doors at both ends, windows, and the electricity and lighting are also designed for the room to be two.
 
Since you talked about soundproofing, I'm wondering a bit about how the wall should look; maybe you can post a sketch...

The difference (as I thought) is that a wall goes between two other walls and completely encloses the space, while a room divider can stop halfway, if you know what I mean? A room divider can be a bookshelf or a screen wall...

What I'm getting at is that if the wall is going to stand for a long time, and if you're thinking of something that turns one room into two "real rooms," I would think it's worth doing it properly, because a future homeowner might also find it beneficial to have two rooms...
 
Otherwise, it's quite stylish with horizontal painted wood paneling. It becomes like a feature wall.

A real wall it will be, connected at both ends as well as ceiling and floor, no openings. Against the floor, I hope to be able to build the wall floating, but it remains to be seen how it works.

Yes, regular pre-painted wood paneling is an option.
