Plasterboard on panel wall??

[janssonj]

Is it sufficient to screw the drywall onto an interior wall in the basement that has paneling on it??? The studs in the wall are horizontal and spaced about c/c 800mm. I'm not quite sure what the dimensions of the paneling are?? I would guess about 13mm...

Should work provided that you have checked so that the wooden studs are not in direct contact with the concrete.

 

[janssonj]

Why should I check it out?? What could happen if that's the case??

 

[Immobil]

There is a risk that moisture can seep into the interior wall. If you have wooden studs in direct contact with the concrete, mold will come like a letter in the mail.

 

[janssonj]

If the studs have been against the concrete for about 30-40 years, then it should have been noticeable already. Because won't it make any difference just because you put up plasterboard on the walls???

Yes, the wall becomes denser as you add a layer of gypsum on top of the existing structure, which can cause more moisture to remain behind.

Tips:

Tear down the paneling, plaster the walls.

We shall do that.

Shouldn't it work even if the studs are against the concrete since my wall studs are horizontal, allowing air to circulate around the entire room, which isn't possible if the studs are vertical. Then we're only going to drywall 3 of 4 walls, so the air can exit that way too. I was thinking of having fabric on the wall that will then be painted. Does it matter what surface treatment you use, in terms of moisture?

 

[janssonj]

Is there always moisture in a basement or is it only if it is poorly drained??? We have a dehumidifier running around the clock in the basement, which should be a clear advantage. The humidity level is now about 40% in the winter.

Well, the wall does become denser since you add a layer of gypsum on top of the existing construction which can cause more moisture to stay behind

Gypsum doesn't make anything denser from a diffusion perspective....

I have determined that there are lecablocks in the wall, then it is framed with 45*45 directly on the leca "horizontally", 45 insulation and then paneling. I haven't noticed any mold or anything like that, does anyone think it would be possible to just throw some drywall on the paneling??? Mr. Z, you seem to know a bit about this, what is your opinion??? The house was built in the mid-70s. The house is located in the middle of Sweden if that matters, as I mentioned, there is a dehumidifier in the basement...

[quote author=mats_o link=1136367146/0#5 date=1136372912]Sure, the wall becomes more airtight since you are adding a layer of drywall on top of an existing construction, which can make more moisture stay behind

Drywall doesn't make anything more airtight from a diffusion standpoint....[/quote]

No, but if you put drywall on top of the panel, the whole construction becomes more absorbent than with just the panel. That's what I meant.

Wood and basements generally aren't considered the wisest of ideas. At the same time, it's important to remember that the reason for elevated moisture levels in the basement isn't solely because it's below ground, but because basements are generally cooler than the rest of a house. You can address the moisture problem by raising the temperature. This works with slab on grade and insulation underneath. The same amount of moisture exists in the entire slab, but the heat on the inside makes the relative humidity (RH) lower.

Of course, you can put drywall on the paneling; it might work, or it might not. In my childhood home, we had wood in the basement and there was no mold. It depends on how the exterior looks, drainage, etc., etc.... But the chance that you'll end up with a microbe fest in the timber sooner or later is considerable....
