...and I used the "asphalt" backed looking stuff from Lowes and its never had a smell to it and we got some 100 degree days the very summer I put it in. Mine is the same stuff but "labeled" as window seal/flashing stuff. For the money I'm happy and like some others, I put the jute flooring down with the rubber mat over top...as well as stuck it to the insides of my doors. 6" strips are easy to work with.
