CANOPUS Car Sound Dampening Mat – 80 Mil, 18 Sq. Ft, Butyl for Trunk, Doors, Floor and Ceiling, Audio Dampening Material, Pack of 9 Sheets, Black

This stuff is thick and worked great for sound deadening my truck doors. I was a little skeptical based on the price but they have great adhesion and are very thick. They don’t smell bad and the foil didn’t tear easily. Definitely plan on buying more for the floor and firewall when I get around to doing that job.

Très bon produit, vraiment très bon, il se positionne facilement, la coupe est aisée, il adhère bien, je le laissais chauffer au soleil avant la pose pour rendre le produit moins rigide, un sèche cheveux doit aussi faire l'affaire. Comme tous les produits insonorisants, il faut vraiment en mettre partout pour que le résultat soit spectaculaire mais rien qu'en insonorisant le coffre, ça se fait déjà bien sentir.

I took great car to install these properly in my cars wheel arches. It made absolutely no difference whatsoever. Pointless.

I installed a stereo system in my vehicle bit the bass was rattling the door panels and it sounded annoying. I decided to purchase these mats and what a BIG difference! The installation was super easy and now I don't hear any rattling and the sound is clear and crisp now. The mats are heavy and of very good quality so durability isnt an issue and I was surprised that they didnt have a strong smell.I must say that they're worth the money and the customer service is awesome! I highly recommend

Amazing. Very sticky. Easy to cut but super strong. Easy to work with. Cut back the sound and the heat in my sxs cab
