Log house

[jonsi]

I have an old log house, or maybe it's more of a shed/cabin. But I am planning to convert the upstairs into a music studio/rehearsal space, so I need to soundproof the walls a bit, which requires slightly flatter walls. Can I attach 20mm chipboard directly onto the log walls? I have a bunch lying around, or what is the best solution!? Does adding building paper between the logs and the chipboard help, or does it just cause more harm? Thanks.

I have an old log house, or perhaps it's closer to a shed/cabin. But on the upper floor, I'm turning it into a music studio/rehearsal space, so I need to soundproof the walls a bit, which requires slightly flatter walls.

Does putting a wind barrier between the logs and chipboard help or does it just cause more harm?
Thank you.

Generally, log houses do move, so if you screw boards directly onto them, there's a risk of cracking... but if it's in a limited area and the house isn't moving that much anymore, it might work.
Otherwise, you should ensure that the boards are attached so that the frame can move behind the boards.

Generally, timber houses do move, so if you screw boards directly onto them, there's a risk of cracking... but if it's in a limited area and the house no longer moves much, it might work.
Otherwise, you should ensure that the boards are attached in a way that allows the frame to move behind the boards.

Thanks for the response.
So what's the alternative? Frame with something like 2" and attach there?
Does wind barrier paper serve any purpose on the inside?

Thanks for the reply.

You have wind paper to prevent it from blowing into the insulation. If you put insulation between the timber and boards, it can be useful.

The overall problem is that you might not want to screw the frames directly into the timber, as you often want it to move with the season. So some form of sliding frames is the right approach.
But if it’s an older dried out structure, it might be possible to screw 2" frames directly as well.... a bit hard to know in advance:

Thanks.

You can place chipboard directly against the logs; the best option might be to plaster with clay.

What are you planning to use for soundproofing? I think the usual process is to use studs, insulate, and then finish with OSB and drywall. You can of course substitute OSB with chipboard, but 20mm chipboard may not fit well with any boxes for recessed electrical outlets.

I've heard that you shouldn't insulate log houses on the inside, but 45mm might not be harmful?

Soundproofing might be the wrong word, I mean more acoustics. Modern egg cartons, if you will, so it doesn't really matter how even it gets, hence I thought of using up the chipboards.

I think the irregularities of the logs are better than the smooth surface of the chipboard when considering acoustics.
