I appreciate you will then have a ceiling below all of that, so it will further deaden the sound. Link to comment Share on other sites More sharing options...

Assume I could wrap the pipe in something tbh Link to comment Share on other sites More sharing options...
Thorfun Posted February 1, 2023 Share Posted February 1, 2023 @Nickfromwales has previously mentioned using Killmat insulation. here's one such example of a post of his   and was something I was going to look in to for our poo-pipe running across the basement ceiling. 1 Link to comment Share on other sites More sharing options...

Onoff Posted February 1, 2023 Share Posted February 1, 2023 I deadened the concealed cistern noise using acoustic tiles.    The poo pipe itself is encased in expanding foam then overboarded with 12.5mm Aquapanel and tiles. Seem to recall @Nickfromwalessaying that's not the best idea (expanding foam), for sound deadening. Works for me. Can't hear a thing going down the pipe.   Link to comment Share on other sites More sharing options...

Spreadsheetman Posted February 2, 2023 Share Posted February 2, 2023 Our main waste runs down in the corner of the kitchen in boxing. I had to have that apart for various other pipework to share the route so when I put it back together I insulated the boxing with rockwool rwa45 acoustic batts 75mm thick. (I had loads of offcuts so was keen to find places to use them). Â It made a big difference, the splashing sound is almost inaudible now. Link to comment Share on other sites More sharing options...

Pocster Posted February 2, 2023 Author Share Posted February 2, 2023 Right!  https://insulationandlagging.co.uk/Acoustic-Insulation/Acoustic-Insualtion-Pipe-Wrap/Acoustilag-Acoustic-Pipe-Lagging  With sensible delivery cost. I need 6m ; but 1 roll does 4.8m around a 110mm pipe - so I'll need to stretch it a bit. Maybe acoustic lag mainly at junctions of pipes? Link to comment Share on other sites More sharing options...
