the carpentry advised against mdf for the sliding doors, what do you think?

[Yrrol]

I would like to have massive sliding doors to dampen sound.

Provide a design based on MDF boards.

But they mentioned the risk of the boards warping when I put wallpaper on them, as MDF is sensitive. The same goes for painting, which should be done on both sides simultaneously.

He advised rather to make a wooden frame and attach boards on both sides of this to get doors that won't warp, plus this would be more stable.

- My question to you is more about some sort of compromise. I'm considering if perhaps one should make frames, but place thick wooden boards inside and then close tightly with the large boards that would then be the visible ones.

The kind of material used for cutting boards, perhaps? But it would be unsightly on the narrow sides... which a wooden frame + two boards would be too, in any case.

If it is sound you are concerned about, then a sliding door is not recommended from the start, as it is so loose in its track construction that all sound goes through there instead. But otherwise, your basic idea is correct, the heavier the door, the more soundproof it becomes.

MDF in the middle and renovation plasterboard on the outside?
But a frame is probably the best, although the plasterboard is convenient for wallpapering.

If you're worried about noise, a sliding door is not recommended from the start, as it is so unsealed in its track construction that all the sound goes that way instead. But otherwise, your basic idea is right, the heavier the door, the more soundproof it becomes.

Yes, I know, but at the same time, there's a lot of clutter inside too, so I'm hoping for a compromise. If you think it through and do the best you can, maybe it will work out.
- a frame door with lots of air inside, however, doesn't feel like "the best you can do"... the question is what I should fill the empty spaces with.

plaster on the outside, well maybe.

Insulation material you fill with and it soundproofs, e.g., foam boards but it also works well to stuff with stone/glass wool.

We made sliding doors for the closet out of MDF. Quite tall (floor to ceiling) and quite thin. Painted with linseed oil paint on one side = long drying time. They haven't warped. The only downside with them is that they're a bit wobbly but they serve their purpose and look good.

I made two sliding doors in MDF, 19mm (or maybe it was 16), painted on the back and wallpapered on the front, one warped badly and the other is relatively straight. So if I were to use MDF again, I would probably choose a different construction. Thicker MDF would probably not be feasible due to the weight.

 

[Yrrol]

If we now talk about the frame model.

Ideally, I should aim for a total thickness of 19-20mm for the entire door.

What planed material should I use for the frame? It shouldn't be too thick, so I'm not forced to use overly thin panels. But at the same time, the frame shouldn't become too weak either.

 

[Yrrol]

I submitted an order with a frame model but asked to fill the gaps with something to make them more solid.

He suggested foam plastic as it is more insulating, but I groaned that I wanted heavy material. I thought of MDF, but he suggested chipboard....

perhaps foam plastic is better than chipboard... (sliding doors obviously won't be very sound-blocking, but you can do what you can anyway)

MDF on the frame will make a good and dimensionally stable construction. I don't know about the sound, can't you just fill it with insulation? You will need substantial thresholds to dampen the sound at the rails, and a large part of the point is lost then.

The wardrobe's wall is so thin against the other bedroom, hence I want to try my best with the doors. Hopefully, they will stay closed for the most part, especially at night and such.

I (and a good friend) built two large doors from double MDF that I glued together to the right thickness. They became as heavy as armored doors but they definitely won't warp.
