Anyone used the quilted fibre sound deadening?

very lightweight and waterproof. 
not sure I buy the fireproof but looks to self extinguish so that is good.

the other forum I am on recommends Kilmat highly (bout half price of Dynamat or other alternatives

 

have asked their thoughts on this product you've suggested

Ok so I have no idea if it helps with heat as it’s not that cold yet. 
 

but...

 

First drive while I’m not sure it makes a big difference... the exhaust note seems to be more rearward and seems that’s likely due to a little less drone in the front of the cabin. 

it’s still loud as f*** but I think there is enough improvement to notice so I guess I’ll do the rear foot wells and under seat plus go all out and cover the hatch floor. 
 

And it’s on special today so basically free shipping at 6 sheets

Initial feedback is that it works. 
you still need to seal the doors with traditional rubber/tar and alloy mat but it helped the floor and hatch area a noticeable amount. 
stuffing the very rear across under the latch with 3layers killed a lot of drone.
