Sound proofing a wooden garden room
Discussion
We’re having a garden room built from timber in a few weeks time - the usual home gym, family room type building. We would like to try to reduce any noise from the room when playing music or watching movies etc. The building will have insulation in the floor, roof and ceiling, is it worth considering any products that might both provide insulation and help to reduce sound?
Over 25 years ago now we built a load of sound booths at Rolls Royce for milling machines to sit in while squealing away.
Basically 3 sided booths, with 2x2 uprights on the wall, rock wool insulation in between the studs, hessian stapled over it, then some sheets of steel with hundreds of holes pressed out onto the hessian, like peg boards but tiny holes almost touching each other, hence the noise goes in and gets trapped.
Ceiling was the same but joists replaced the 2x2.
Once finished they worked very well and not an egg box insight.
Something similar would be easy enough to build.

Have a look at this feller who builds a comprehensively soundproofed garden drum studio. There's others on Youtube from people who soundproof their garden rooms in various ways.

Also church out the recent video by Gosforth Handyman where he talks through soundproofing his outdoor room/studio/workshop.

The proposal is to install 75mm Rockwool along with multi foil insulation in the walls and then finish off with decorative MDF interior panels rather than plasterboard to avoid future cracking of the plastered finish.
The windows and doors are all aluminium double glazed units with integral aluminium blinds.

I kind of thought he ruined the whole thing (having a floating, isolated walls & floor twin walls plus lots of other details by having a bloody great window at the front! He seemed happy with the end result though.This guy built a huge heavy removable window box including cement board to completely block the sound going out the window.

My concern with complex soundproofing for garden rooms would be damp - and how you'd ensure that moisture wasn't gathering in the layers that you might be sealing up attempting to soundproof itn (this woudl cause problems with plaster inside, and rot any wood the moisture stays in contact with) - you'd need to make sure your breathable/ dampproof membranes and ventilation are in the right places to avoid this.

I think I'd want another layer of something with a different density if you're really concerned about noise.The windows and doors are all aluminium double glazed units with integral aluminium blinds.
