Ty for the info!
I did quick googling..
Polyethylene is used in larger ponds.. thicker, harder to bend etc..
Polyethylene Foam Roll's best application as a soundproofing material is as a sound barrier in or on walls, ceilings, or floors. It is most effective when used as a component of a multi-layered construction scheme.
I guess these are two very different products made from same material.. foam roll being more airy.. Yet.. I do think that pondliner might work as soundproofing material also ??
can you (or someone else) offer insight on this aspect?
