Why does Noico's 36 sq ft of 80 mil matting weight 27 lbs, but this mat with supposedly the same specs weighs less than 17 lbs?

my guess is it's due to the density and/or the specific weight of the material. like 80 ml of rubber would be different than 80 ml of lead. I purchased the Siless as the most economical choice. I would like to be able to compare products as to their damping performance specifications, (not available) but a choice for the lighter weight material was a plus.I used 108 sq ft of Siless and saved 30 extra lbs weight that wouldn't have helped my electric vehicle's battery range. I also added a 157 ml layer of their sound matt overtop. I own a very quiet ride!

Will this help reduce engine noise in a diy generator box made of plywood? (to inside walls away from exhaust)

Thank you for your question. You would get much better results installing butyl based material on metal. With plywood, it won't help you much.

Can this be used a a heat sheild for a Wood stove

Thank you for your question. Siless 80 mil sound deadening mat is not recommended to be used as a heat shield for wood stove.

Could you use this to keep music room noise from bothering neighbors? Specifically, could you put it on a wall?

You could put it on walls. But as for suppressing noise from a neighbor, I don't think so. It's best to use acoustical tile for rooms.
