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 lightweight 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.

Easy to use and effective

By: on 6 August 2018
I used Stage 1 Sound Deadener for my van. Even as a first-timer, the product was very easy to apply to roof, walls and floor using the application roller.


Stage 1 sound deadener.

Easy to use, just peel and stick. Some cutting around irregularly shaped areas, but it was not difficult. It is fairly heavy, and I estimate probably close to 100 kg increase in weight for a Mercedes Sprinter. The difference is beyond comparison, from a rattly booming van, to a quiet ride in which I can hear the stereo without turning it up to kill. Brendan from CarBuilders was most helpful, and I would recommend dealing with him.

Great product and arrived quickly, very happy

Great stuff to use....even in the depths of Melbourne's cold winter......STICKY......EASY TO CUT/PLACE.....STRETCHES DOWN TO THE BOTTOM OF ALL THOSE SWAGES AND DRAIN HOLES. You don't need to stick it EVERYWHERE!!!! like u see on the Internet.......just tap on the surface to see if it drums......if so, then go ahead. Just make sure the surface is clean before u start.....Prepsol or metho make for great surface preparation. Buy and use the roller to save yourself some grief, the urethane roller is MUCH BETTER than a hardware store version. Use the back of the handle to squish into corners and grooves. Disclaimer. I'm a friend of Brendan's but I chose the product because of its quality.

Install in Ford XRAnniversary

By: on 7 March 2016
I received great advice from Brendan from the first enquiry that I made. On his advice I purchased the sound deadener install kit. It was perfect for installing on all four door skins. The results are beyond my expectations. Road noise has been substantially reduced and sound quality from the stereo has been improved. If I change cars I will be back car builders for more product to install. Cheers

Just fitted sound deadening on the engine cover, rear deck and front doors on my Hillman Imp. Totally killed most resonaces and rattles, car much more civilised. Very easy to fit

very quick postage, can not fault the product. installs really easy, purchased for a car audio install and i am extremely happy with more rattles from the boot or front doors,will definitely be getting more


Highly effective

By: on 24 January 2016
I used the sound deadener in the boot well,doors and rear quarter panels of my new Toyota 86 to reduce road noise and was pleasantly surprised by how effective it was. It was easy to cut to shape and install with minimal mess. I then added the 6mm acoustic foam to the rear of the trim items to further enhance the sound deadening qualities.
