Acoustic and Thermal Insulation/Soundproofing a Stone Shed

Postby cojobt » Fri Jan 24, 2020 2:29 pm


I am considering converting an old stone shed with slate roof and concrete floor into an amateur sound studio, mostly for mixing. Three walls of the shed are bare stone, with one wall being the gable end of a bungalow.

From what I have read, this will involve dry-lining the room, or possibly creating a floating room. I won't require professional studio-standard soundproofing, as we're in the middle of the countryside, but I'd like to eliminate the sound of passing cars, tractors and also the wind, and contain the noise coming from the speakers.

The roof was renovated recently, but there are lots of large gaps between the wall and the ceiling which need to be built up.

I'm researching the best materials for good thermal and acoustic insulation. So far, Knauf Rockwool RWA45 appears to be a good option, at 40kg/m3, but it's costly.

If the walls and ceiling were dry-lined with this at 100mm, would that make the room reasonably soundproof, and also easy to heat with a small heater? The shed is 14'x10'.

Are there any cheaper options?

I acknowledge there are a lot of variables at play here, but I'm just at the beginning of this project, and trying to assess its viability, and the cost.

There will be no plumbing, but it will have to be wired too.

Thanks for your help?
