Thread: fire wall sound proofing

Hey Shane - I may have addressed this with you some time ago ... I read the EZ Cool story by that "nutter" a while ago and was impressed.

Since then EZ Cool has been on the top of my list though I have been balking at the freight quoted to Perth for sufficient to do my RRC 4 door.

Do you know if you can get the stuff or similar anywhere in Oz? I'd hate to order it up and receive only to find its no different to the leftover roll of shed insulation I've had for 5 years ...

EZ Cool Automotive Insulation heat barrier and noise reduction for cars, trucks, classic cars, street rods and much more

I know some nutter that tried it out and found it ok. It weighs nothing at all.

seeya,

Sound Deadener - Car Builders - Sound Deadener Heat Insulation Car heat Shields

I used the waterproof version from Car Builders intended for 4WDs. Just measure, cut, peel and stick. Then I put the original mats back

I'm looking for something to sound deaden the firewall too. Mine has leaked in the past (haven't had enough rain over the past 4 months to see if it still does!). But I was thinking that the butyl based ones (like Dynomat etc) that have no foam type material and adhere directly to the metal surface and if installed properly, shouldn't allow any water to get trapped. Running the sheeting from the floor up onto the firewall in one continuous piece could actually help keep moisture away from those vulnerable areas?

I totally agree with you and Mick in using something that is actually designed for the job. Why would anyone bother with the time and trouble to install a product that wasnt?? Do it once and do it right! It will be cheaper in the long run. You can also get heavy sound deadening matting made just for Defenders like this one R380 Mat

Just had a look at their website and there doesn't appear to be anyway to contact them and no prices mentioned. I'm also looking for options for the firewall plus to cover the tunnel as well. Removed the old A/C as it wasn't working and now have heaps more leg room but have the firewall more exposed leading to louder noise inside....

This thread is quite old now (9 years) but I was wondering if anyone here has tried the 'wrightoffroad' mat solution? A quick google suggests it is also sold by Exmoor trim but getting a price is still a challenge. Would also be interested in how you get around the Oz spec a/c intruding into the passenger footwell.

Cheers Simon

I didn't find any problem with the air-con vent. I have also fitted a snow cowl over the mudguard vent to stop rain water coming in through the heater.
The closed cell stuff from Car Builders I used is waterproof anyway.
I have some left over so I'm planning to fit even more of it, when I get a chance. It's a dead easy job - measure, cut, peel and stick.

Thanks Discmick. Sounds good and the Car Builders stuff is locally sourced and pretty cheap from what I recall. Did you seal the panels with Waxoil or similar to prevent rust if any moisture got in?
