Noise proof my 💩 pipe

[Pocster]

My nice black poo pipe below the beam and block can be quite noisy when a toilets flushed .

What should I use to lag it and reduce the noise ??

We framed ours out, faced that in 11mm OSB, then 12.5mm plasterboard, that silenced it very well. I appreciate you will then have a ceiling below all of that, so it will further deaden the sound.

Only a suspended ceiling so not expecting that to dampen sound much . Assume I could wrap the pipe in something tbh

@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.

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.

50mm mineral wool works a treat and dead easy and dead cheap.

Women testing flow, mid stream, is something to worry about.

£54 quid delivery!!!!!

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).

 

It made a big difference, the splashing sound is almost inaudible now.

wtf!

 

I'm tempted to go with Rockwool held on with gaffa tape!

[Pocster]

Right!

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?
