We import 6lb.ft density, which i think might be 705? we do that as the stuff in this country doesnt come in big enough sheets for our purposes, the 25mm we used to use years ago wasnt consistant enough. I dont know what alternatives there are though

The stuff we used to buy were small, only 1.5m i think, but i dont know if they are still avialable, i will find out for you, the sheets we import are 2.4 or 3.0m long but i dont know if they are available for sale, again i will find out and get back to you

Rocksil RS45/Rockwool RWA45 - 45kg/m3 and..

Rocksil RS60/Rockwool RW3 - 60 kg/m3 are...

The rough equivelents or 703 and 705.

OC703/705 is glasswool ( glassfibre ), while rocksil and rockwool are mineral wool.

Either works great. If you specifically fancy glass fibre then a company called Isover sels in EU/UK

hi, i've just joined this forum after searching the internet for some sound proffing advice. Here's a few tips for anyone wanting to build stud (partition) walls for their studio. (i'm a shopfitter by trade)

materials

As someone has said, use a builders merchant for your materials. Buy your screws by the box (much cheaper). for stud partitions, The minimum size timber you should be using is 75mm x 50 mm (3"x2"). Plaster board comes in various sizes, mostly for ease of handling. i.e to let the DIYers get it in their cars from the DIY sheds. a Standerd size sheet is 2400mm x 1200mm. they come in square edges for plastering and tapered egdes for drylining. the drylining method entails fixing the boards with 40mm gyproc screws and filling the screw holes and the egdes of the board with gyproc easi-fill. This can be done to a reasonable finish by anyone with time and a bit of DIY knowlege

construction

a stud wall consists of a head, a sole and legs. the legs are fixed with 3" nails through the head and the sole at 400mm centres. however, and heres a trade secret for you, make the distance betwen your first and second stud 375mm this will ensure your boards finish in the centre of the a stud, enabling your next board to fix onto it. when measuring your legs, measure both ends of the room along the lenght of the wall in case the floor and ceiling is running out of level and allow about a quarter of an inch gap clearence. Mark your centres on your head and sole and then nail the legs. once nailed, nail a row of noggins through the centre, this adds stability. lift the wall up into place and fix it top and bottom every 3 ft (900mm). Once it's fixed you may need to add further noggins to attach socket boxes, switches etc. It can then be boarded either with square egded or tapered boards. If your going to give it a double skin of boards, rememebr to stagger the joints. i.e if your first board it 1200mm make the first board of your second skin 0r 900. fix the boards with gyproc screws, easier than nailing, 40mms for single skin, your second skin will need at least 50mms. If your going to insulate it with cosy wrap, (sorry slang name for rockwool) board one side first. It might seem obvious but i did have one of my apprentices ring me and say "i can't get the cosy wrap to stay in the wall". cosy wrap is 400mm wide so should fit between your studs quite nicely. If your room is higher than 2.400mm you will also need a row of noggins 2.400 mm high to catch your next row of boards.

ps the method i have described assumes you have enough room to build your wall on the floor and lift it into place. if it has to be built in situ, simply fastenign your head and your sole to the ceiling and the floor and fix your legs individually.

I'm slightly confused here. Mattrpg says the 705 is 6 lb/cu ft. If you bear with my maths for a moment -

1 metre = c.39" so 1 m3 = 59319 cu ins.
1 cu ft = 1728 cu ins
So 1 m3 = 34.21 cu ft.

1 kg is about 2.2 lbs
So 60 kg/m3 is 132 lbs

132 divided by 34.21 equals 3.85 lbs/cu ft.

Roughly speaking, you would need to go up to 100kg/m3 to get to (a little over) 6 lbs/cu ft. I'm happy to be challenged on my maths here!

Otherwise, from the point of view of comparing US and UK brands, is it in fact fair to say RS60 is broadly equivalent to 705?

There is a start kit from a swedish company, that has been sold to a lot of swedish home studios.

...... amazing.

Just read through this list and it thoroughly astounds me that after all this time, and after looking at what some of you do , that many still do not comprehend the vast distinction between soundproofing and acoustic treatment. How helpful exactly is that for the novice's that frequent here when even some of the "recording professionals" dont know? Auralex foam to soundproof ? COME ON PEOPLE.....

now then everyone...thanks for the great advice i've found here...been of great help!!!

just a quick line...just had the quote back from Travis Perkins for my 60mm, 60kg/m3 rockwool type slab and, for 100 square metres they reckon £500 give or take a few pennies.... is that good or bad?

any ideas?

Assuming the RS-60 price is inc vat, that's pretty cool.

otherwise try these guys who supply 2.4m2 packs (50mm or 100mm thick) about £16 inc vat. I'm sure they'd do discount on 40+ packs.

we treated our practice room with acoustic foam and it made a big difference, we were given a contact by a guy we know who recently refurbed his studio in manchester
heres their site

www.acoustic-foam.co.uk

and not bad prices compared with some

I have seen some stuff advertised as good for reducing noise from computer cases (www.mutemat.co.uk) Has anyone tried it for other noise absorbing areas as all that I seem to see else where is Foam?

big difference? what is that in terms of acoustics - reverbertion time reduction?
acoustic foam will only control reverberation and will not be effective at soundproofing unless you are only looking for a nominal reduction in transmitted noise - less than 3 dB which is unlikely.

tried emailing and asking acoustic-foam for low frequency data a couple of times but no joy.

the low frequncy performance is very poor and there is no data from any of the configurations.

can anyone help?

Has anybody used this material as a replacement for plasterboard or had any experience of it?

Large Foam 'panel', neatly pre-contained in a cotton cover - for £15

call me 'out there' but could THIS have some acoustic potential? - maybe as the front of a large framed bass trap with rockwool behind?

It depends entirely on whether it contains open cell or closed cell foam. Here's a good description of the difference:

www.foam-tech.com/products/urethane_foam/open_closed_cell.htm

Open cell foam is ideal for acoustics, because air can enter it and be absorbed, but closed cell is useless. Sofas commonly use both open cell foam (for softness and comfort) or closed cell foam (firmer and more resilient). Beds commonly use closed cell foam because it provides more support. I suspect in this application the fact that open cell foam can absorb liquids would also work against it.

So, I suspect an Ikea mattress of that size would use closed cell foam, and therefore be useless for acoustic purposes. On the other hand, perhaps a smaller baby mattress would use softer open cell foam.

You'd have to ask Ikea or try blowing through the mattress to see which it is for certain though ;)

I have planned to use just this material in my floor, on top of a few other layers, as base for final, hardwood flooring. It's supposed to have more mass as well as more stifness than plasterboard. As I said: still have to start works, can't comment on it yet, but I did choose it after carefully comparing specs v/s plasterboard.

Hi Paul,

I can't say I agree with everything you say in your post.

The first point is about exotic soundproofing materials like vinyl mats. If you've ever tried to lift one of those mats you realise how extremely dense and heavy they are (usually 5kg/m2), much more so than plasterboard. Yes you probably could get the same soundproofing with 2 or 3 layers of 12.5mm plasterboard as with one vinyl mat but that would be 25mm thickness as opposed to 5mm. That's might be a really important consideration for some. Two or three sheets of plasterboard probably will not work out much less in terms of cost than one sheet of the vinyl anyway. The vinyl mats are around £5-6/m2 so two or three sheets of plasterboard, even at £2/m2 (which is a good price) ain't that much cheaper. I'd rather go down the exotic route and pay the same or a little extra to have the thinner wall.

To be fair I've found with the specialist suppliers that they are prepared to price match if you can show them, for instance, the acoustic sealant price on screwfix or the RS60 price from other suppliers.

The second assumption I would question is that it can all be done with rockwool, timber and plasterboard. For real bass absorption (i.e. if you don't want to hear your drums on the other side of the wall) you will need to go down the isolation / resilient bars route. Try asking a builders merchant for resilient bars.

Apart from that I found some good food for thought in your post and I would be interested to know what it is about studiospares that should be avoided - is it their acoustic treatment materials (which seem a bargain compared to auralex) ?
