Mike_scotland Posted December 4, 2021 Share Posted December 4, 2021 Hey group, Can anyone recommend a good level of acoustic insulation? Currently on the building warrant its 25mm acoustic wool but i imagine thats the minimum/basic between the rooms, im hoping to get some good sound proofing. Thanks in advance!

nod Posted December 4, 2021 Share Posted December 4, 2021 If your only insulating between rooms 25 mil of acoustic is normal It’s literally to stop the sound rattling around The majority I use on commercial is 25 and 50 Link to comment Share on other sites More sharing options...

There’s a lot of confusion with soundproofing Many of the house builders have us filling bathroom and toilet walls with 70 mil of loft insulation Which does hardly anything We fill office and split student rooms with 25 mil Party walls between blocks with 50 mil As long as you use Acoustic (ISO) 25 mil Will do the job 100 mil lap at the top and bottom Staples to hold it in place 1 Link to comment Share on other sites More sharing options...

Nickfromwales Posted December 5, 2021 Share Posted December 5, 2021 I've never seen less than 75mm installed on domestic B-Regs installs. I usually spec 100mm acoustic with soil / waste pipes 'boxed in' to eliminate the noise of water flowing. I would not want 25mm in my house tbh, and didn't even know this could be bought at 25mm!!

Box ( surround ) all waste pipes with the same as well as you can. 1 Link to comment Share on other sites More sharing options...

It depends what you want to achieve - it's not only the insulation quit - it's also all the other components of the partition, and whether you're only concerned with airborne sound, or if impact sound is an issue. Knauf and British Gypsum both produce useful guides. FWIW, the partitions on my next project will have staggered studs to physically & acoustically separate the two faces of the partition, with 1 layer of ply and 1 of plasterboard each side, 50mm acoustic quit between, and acoustic sealant at all edges and joints. If I was using all plasterboard instead of plasterboard + ply, that would give me 57dB nominal sound insulation.

SuperJohnG Posted June 20, 2022 Share Posted June 20, 2022 @Mike_scotland what did you end up doing? I'm in the same stage right now and swithering to just get lots of 50mm or put 25mm somewhere? Link to comment Share on other sites More sharing options...
Arnold9801 Posted July 27, 2022 Share Posted July 27, 2022 I'm about to buy 100mm acoustic insulation from b&q for above the downstairs ceilings/upstairs floor and hope this, will suffice? Anybody willing to comment. It would be appreciated. Arnold9801 Link to comment Share on other sites More sharing options...
