Anyone knowledgeable in the use of lead sheeting for sound proofing ? I have an 2800 Onan generator Im going to install under my van. I'm building my own mounts incorporating 5 anti vibration mounts and I was going to coat the plastic generator cover with 1/32" lead sheeting. I have 1/4" closed cell foam I was going to sandwich the lead. What happens if I only cover the foam on one side or no sides on the top as I'm trying to mount it as close as I can for maximum ground clearance. The ventilation ports will not be covered. I think I understand you need foam to allow the lead sheet to absorb vibration/sound but do you need it on both sides?

I my search learning about soundproofing i do remember reading in several places that lead makes a great soundproofing. For most applications the weight is an issue though. I think you might have an issue with heat retention using it? I'd check with the generator manufacturer on that.

Heres a product used in marine applications that might be better?

Again you have to look into how close you can apply this without heat being a problem for the material.

The cover is thick plastic so its not designed for heat transfer, the MFG doesn't want you to put anything inside and affect the cooling air flow.

I would not recommend the use of lead in an application where people have potential interaction with it all the time.

Buried inside your battery is one thing; within the interior of a vehicle is quite another.

A lot of old homes have lead paint, just don't eat it and should be fine^^^
