Thorfun Posted October 30 Share Posted October 30 my thoughts are slowly turning to kitting out the basement and I think the first room I'll do is our music room so I can start playing musical instruments again! I need to soundproof a lot to reduce the noise carry of drums and electric guitars/bass etc. I was going to double skin with soundbloc but I was wondering what the hanging capacity of it is and whether I should do a layer of 18mm ply and then Soundbloc on top so that I can fix things to the walls without worry of them falling off. I'm thinking things like a PA, guitars, instruments, speakers etc. I'll be using metal frame to build a room within the room to reduce vibrational sound transfer and the Soundbloc will attach to that rather than dot and dab on to the concrete/blocks. anyone got any thoughts on this please? ps. before anyone mentions that the doors will be the weak point I am planning on having double-skinned doors, one inward opening and other outward opening with an air gap between to help reduce noise transfer through the doors.

Thorfun Posted October 30 Author Share Posted October 30 hmm....maybe a layer of fermacell with Soundbloc on top would be better than ply with Soundbloc on top? Link to comment Share on other sites More sharing options...
Mr Punter Posted October 30 Share Posted October 30 Yes, 18mm OSB and 15mm soundbloc works well. Sockets are also weak points. Fermacell is a pain to use. 1 Link to comment Share on other sites More sharing options...

nod Posted October 30 Share Posted October 30 You could use an Abito board Fix and skim in the same way as plasterboard Its extremely strong and will absorb a running kick and you can hang an elephant off it 1 Link to comment Share on other sites More sharing options...

Russell griffiths Posted October 30 Share Posted October 30 I’ve fitted 18mm osb then fermacel on the walls in my plant room. know as it’s being fitted out I’m finding I’m still unhappy fixing into this lot with heavy expansion vessels, so I’m using hollow wall toggle fixings that will drill through both sheets and then open out in the stud wall cavity, I can actually hang from the brackets I’ve put up with just two fixings in. 1 Link to comment Share on other sites More sharing options...
crispy_wafer Posted October 30 Share Posted October 30 (edited) 2 hours ago, Thorfun said: good to know! thank you. 🙂 I assume fixing OSB or Ply to metal frame isn't hard? I've been using these GTEC screws for fixing ply, plasterboard to metal frame (C Stud or Top hat and res bar), I picked up some crappy self drilling screws from screwfix, and butchered the plasterboard as they didn't drive into the metal very well and just spun around in the board making a mess. Siniat GTEC 32mm Drywall Screws - ADA Fastfix Ltd Pricing note, I'm paying 13 + vat for 15mm GTEC Soundbloc, and 10 + VAT for 12.5 Soundbloc, not in massive quantities. I'm taking 30 or so at a time as I dont have too much space to store, and not leaving outside now its got a bit damp...

That’s really interesting especially as Fermacell alone says it can take 30kg per screw by itself! I wonder if I’m overthinking it all as usual and for a couple of really heavy fixings just use multiple of those big bad-ass plasterboard fixings (https://www.gripitfixings.co.uk). They state 113kg which is more than a speaker for a PA system. Link to comment Share on other sites More sharing options...

Plenty of fixings for plasterboard that can be used for high loads. More a matter of using the correct fixings for the job. 1 Link to comment Share on other sites More sharing options...

And all my overthinking was in vain as I cannot find sound blocking plasterboard in 900x1800 sheets. I can’t fit standard sized boards down the stairs to the basement so looks like I’m just going to have to use double skin of standard plasterboard and live with any noise that gets through. 😢 Edited October 31 by Thorfun Link to comment Share on other sites More sharing options...
