Recommendation: mass loaded vinyl vs. lead for pipe noise reduction
Recommendation: mass loaded vinyl vs. lead for pipe noise reduction
(OP)
Hi, I have gotten quotes from two different pipe insulators and they each recommend a different product for reducing acoustical noise on our water pipes. One uses mass loaded vinyl an absorber and the other uses pipe coverings that include a lead and foam composite. My question is if anyone has any experience in the performance differences between the two products? Are health concerns the main reason that insulators have moved to vinyl instead of lead?

Pcking sound treatments is often a question of suck it and see. Roughly speaking performance will be proportional to mass per unit area, but a system that offers 100% coverage will probably be superior to one that offers 98%, and there are frequency dependent effects as well.

The "hazards" of lead are vastly over-rated; as long as you're not storing your wine or drinking water in it, nor feeding it to kids, you should be OK.
