There's also Fatmat , there different grades/types I think.. I bought fatmat extreme , 45 mm thick. I'll be doing my back hatch(van rear door) and the front doors.
I found it and bought it on ebay, but there is an actual brick and mortar store called dalfen auto based out of Oakville ontario.

Havent used it yet but its somewhat local(as compared to over the border), and it reads like it could be good stuff.

 

All of them, some could even use a second layer. I have 2 layers on my trunk lid and the rear deck in the cabin.
