Yeah, B Quiet is for sound and thermal and worked great on my coupe. I paid $169 cdn for 50 sq feet of it from them and it did the whole floor, firewall, and I had some left over. Good stuff, easy to use, but DON'T LET IT GET STUCK TO ITSELF!!!! If it does it's all over, you won't get it apart! A friend in eastern BC used it in his A coupe throughout and said it was incredibly quiet!
