I don't know what it is called.
I use this silver reflective bubble stuff on my windows to keep the sun out in the summer and the cold out in the winter.I have to replace the front carpet. Can I use this bubble stuff under my carpet...

The product they use on fire walls in vehicles is called Dynamat or HushMat, both are an EPDM like rubber with a foil face. It will offer some insulative value as well as sound dampening.
