okay, call me paranoid. Anyone can correct me if I'm wrong, but I'll bet the reason the foam-backed carpet isn't fire rated...is...well, because it BURNS!
Yes, the foam is a great sound deadener I suppose, but think twice about slathering your interior in this toxic smoking stuff!
There are quite a few hi-temp acoustic mats available for hi performance sports cars etc. that will not fill your cabin with thick smoke in the first 30 seconds of a fire. ( Summit Racing etc.)
Where I added some of the common 'aviation' foam under the floor carpet, I sandwiched in double thick aluminum foil, taped all seams, and set on top of a fibreglass matt. All carpets & upholstery were soaked numerous times with Flame-Out solution.
My unscientific burn tests showed a much improved time before any smoke was evident. Lots of previous threads with Dan Hortons's awesome testing results.
Just hate to see anyone go fast, cheap, and easy, and regret it later!
