Home Studio Setup - Acoustic Insulation

[framey]

Sorry if I've posted this in the wrong forum but none of the others quite seem to fit.

I'm getting a (detached) outbuilding built at the bottom of my garden and my plan is to soundproof it to death, then use it as a music room. It's going to be quite a decent size (prob 4m x 4m set aside for my wee studio) and made of standard double skin construction up to standard building regs, but I'm currently looking at cavity wall insulation that also doubles up as acoustic insulation. I also need to stick some in the roofspace.

So... wondering if anyone has done anything similar, where you got the acoustic insulation from and whether you have any top tips, whether financial or otherwise.

Cheers

I converted my Garage to a little music room/studio , the floor was rubber coated then damp coursed plus solid rockwool blocks @ 3" thick iirc then flooring chipboard then a wooden floor with appropriate underlay . 4" rockwool in the stud walling 6" in the ceiling plus acoustic tiles ,,,,seems to do the job http://www.flickr.com/photos/6406907...in/photostream

just remember it;s 2 seperate tasks

1. stopping sound getting out

2. making sound inside decently balanced eq-wise


You just want to put a decent gap between the inner/outer walls filled with decent insulation (or poured sand).

As far as INNER eq/acoustics - get the dimensions right first. Search for "good room ratios" (the difference between width/length & height), while remembering the regulations about OUTER dimensions:

To build a shed type building within 1 meter of your boundary:

1. INNER floor space of no more than 15 sq meters

2. it cant be taller than 2.5 meters

if it exceeds those sizes you must build at least 2 meters from boundary fence/walls

also it cant use up more than xx% of your TOTAL outside space - see regs here (a good FLASH planning widget):

I'd plan for an inner fit of 4"-6" and line it with cross-lined acoustic plasterboard on resiliant-wall-bars, same on the ceiling using resiliant-bars; and of course the usual stuff of not having the ceiling/wall plasterboard meet the actual walls/ceiling and filling the gap with acoustic mastic

If you use a flat roof design (the only practical solution for a studio) you can always create a ceiling gap filled with sand (sand is a fantastic insulator), then cap it off with sheet ply and felt it. (hot felt finish of course) -

So - ceiling joists - hang sheet ply under joists to seal, drop sand in from the top, cap it with sheet ply and felt/finish

Then hang an inner suspended acoustic ceiling from the joists/sheet using resiliant-bars & cross-lined acoustic plasterboard filled with acoustic material.

using resiliant bars + crosslined acoustic plasterboard, with proper acoustic insultion and sealed correctly round edges, will cut around another 20dB

you must be budgetting for about 10 grand yes? inc' leccy wiring from house (you'll need a new spur wiring with it's own fuse), plus a door & window. (which must meet insurance regs if you plan to insure the contents)

Finally dont forget the floor. Good thick carpet with thick underlay and maybe a floor-ply-sheet subfloor sitting on acoustic sheet

You also might want to plan for an extractor (condensation build up) and/or a cheap aircon uni (about a grand for a samsung or delongi unit)

if the contractor aint buying the materials go WICKES (get a discount card) or better still, TRAVIS PERKINS (they own wickes); again get a trade card.

make sure u use proper acoustic plasterboard

familiarise yourself with the products - resiliant bars etc.

Jim. That is a totally bodacious post, dude.
