Car Builders Sound Deadener is a vibration (sound) dampening mat. The material consists of an anti-drum noise absorption layer, combined with an aluminium top layer forming a heat and acoustic barrier. Its pressure sensitive self-adhesive back conforms and fuses easily to sheet metal and other hard substrates. It has excellent performance for acoustic dampening under varying temperature ranges and is highly resistant to aging.

Butyl Mat is today’s alternative to traditional bitumen body dampening. Our Sound Deadener is best suited to restorers, repairers, vehicle builders and audio enthusiasts, who demand acoustic and heat insulation as bench marked by leading automotive manufacturers.

Awesome product super easy to use


Stage 1 kit! Great product and speedy delivery

By: on 8 May 2020
I bought the stage 1 kit for a 78' Mini and it's great to work with. Does what was advertised and the online videos are handy when it comes to installation. I'd recommend this product to anyone doing an interior restoration who is wanting soundproofing and an extra layer of surface protection. Cheers CarBuilders, will be purchasing from you again.

Got my delivery super fast and hassle free. The body deadener is awesome, love it so much I'm gonna leave it all exposed. Easy to install and fix if you make a mistake. Anyone can do it if you have the roller. Used it in my xf Skid car and came out beautifully. Thank you soooo much guys for the amazing products keep up the great work


Great Value!

Insane shipping time, got here in Adelaide about as fast as it gets. Quality is as good as Dynamat and packaged better, my Dynamat was a bit crushed and folded but this come as perfect flat sheets in the box, the butyl feels the same sticky as dynamat for legit half the price!


The difference is incredible

By: on 5 September 2019
I bought a stripped-out '96 Hiace Commuter van to convert to a camper. I love the van but the noise inside was like an assault, almost unbearable. I bought two packs of the noise deadener and used them on the wheel hubs, the floor and sides, wherever the metal sounded tinny or echo-ey when knocked, as I didn't have enough to do the whole van. The difference was quite remarkable, and the van is now a pleasant drive. I consider the product worth every penny.

Sound Deadener Kit - Great Product ... Easy Instal

By: on 14 July 2019
Product was very pliable which made the installation ... relatively easy. The sound difference to my Toyota Hiace Commuter, which I use for my passenger shuttle business, was "Night & Day". After the install, the level of noise dropped significantly.


Tranquility mats

Purchased these to sound deaden my Hiace camper conversion. Installed them on the flat roof panels, wall panels, wheel wells and doors. The difference is insane! Two boxes (3.6 sq m) allowed me to cover about 60% of all the panels and 100% of the rear wheel wells in a 2006 LWB. You don't need full coverage to get great results - covering about 50 to 70% of any panel is enough to take the ring out of it. Can't recommend these enough for anyone looking to improve the quality of their ride while driving and while parked/sleeping.
