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? doesn't give any sort of sound reduction values though.

Pocster Posted February 2, 2023 Author Share Posted February 2, 2023 Maybe ? https://thermalinsulationonline.co.uk/shop/pipe-section/rockwool-pipe-insulation-sections/ It is in essence just rockwool ( so no sound spec ) but saves boxing in.....

I guess it all depends on how thick you want it. our heating engineers used this type of stuff for our ASHP flow and return internally. Link to comment Share on other sites More sharing options...

I’m going to use my phones decibels measuring app at discreet points along the pipe ( mainly where wc enters ) . Get some readings before and after lagging . 1 Link to comment Share on other sites More sharing options...

I know, lets all do a comparative table: get our respective OHs to perform, send the results to @SteamyTea - who would anonymise the results , work his Excel Magic and then publish them. 1 Link to comment Share on other sites More sharing options...

JonBATConsult Posted May 23, 2023 Share Posted May 23, 2023 Standard rockwool pipe lagging works quite well. Upgrade this to a mass loaded vinyl around the lagging Link to comment Share on other sites More sharing options...
