## Questions & Answers

**Q: 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?**
A: 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!

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

**Q: Can this be used a a heat sheild for a Wood stove**
A: Thank you for your question.
Siless 80 mil sound deadening mat is not recommended to be used as a heat shield for wood stove.

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