rule simple wall cc?

[läppglans]

Hi, I was thinking of putting up a new wall with about 1cm distance from the existing wall for the purpose of soundproofing from the neighbor.

I was planning to use a layer of 120cm gypsum 12.5mm that I already have, on 45mm steel profile with mineral wool in between.

The question is if it's enough to stud at cc60 if you want to hang a flat-screen TV and speakers on the wall???

Place OSB behind the drywall and you won't have any problems! Otherwise, you should add studs behind the TV or attach to a beam.

if you want to avoid OSB and noggins and go with cc40 instead, will the durability be sufficient then?

Not to hang up a TV at least, I would never hang it on just plasterboard. If you want to avoid OSB, at least reinforce properly where you're going to have the TV. It doesn't take up any space from the room if that's what you're worried about. But 11 mm doesn't seem like a danger to "steal." Then there's also special acoustic insulation, I believe. The magazine Do It Yourself had a description a few issues ago on how to build a soundproof wall in the "best" way.

It is not the stud spacing that determines whether you can hang a TV or not. If that's the only concern, then cc60 will definitely suffice. The issue that can cause problems is the sheet material.

Isover has a board called Piano Ljudskiva that is supposed to be more suitable for sound insulation than regular insulation.
costs not many hundreds... for example:

You can hang a flat TV on single drywall using, for example, molly plugs. It is sufficient with c/c 600.

Just a tip... use 45 or 30 cm spacing and buy 90 cm boards... incredibly easier to work with than the 120 ones... Alternatively, space at 60, apply OSB, and then 90 cm gypsum on the OSB...

Yes, of course you can. But I wouldn't have done it... And what incredibly ugly holes it will leave if you want to remove the TV...

 

[Daniel78]

Sure, of course you can. But I wouldn't have done it... And what terribly ugly holes there will be if you want to remove the TV...

Terribly ugly holes?, if you take a small wire cutter or needle-nose pliers and "tear off" the visible "front" of the molly, you can push the plug into the wall, and you then only have a hole that has the same diameter as the plug.

Terribly ugly holes?, if you take a small side-cutter or needle-nose pliers and "tear off" the visible "front" of the molly, you can push the plug into the wall, leaving only a hole with the same diameter as the plug.

Many probably consider those holes as "terribly ugly".

 

[Daniel78]

There are probably many who consider those holes to be "terribly ugly".

But they don't end up worse than a hole from any screw/plug, so you'll have to fill them or hang a picture anyway

I think Molly is absolutely wonderful to use on drywall, quick and easy to install with the right tools.

 

[petersson79]

Yes, but if you put some kind of particle board behind it, you completely avoid those big ugly plug holes...

When it comes to soundproofing, TS should of course install (at least) double plasterboard.

And a high-quality plasterboard molly can support almost 100kg in load, right?
