View Full Version : Sound insulation for Defender

Here is the start for installing some sound insulation for my Defender. The metal foil backed stuff is some Butyl RAAMmatt from the U.S. Have 1.5 Rolls of the stuff. The Vynil is heavy 2.5mm sound insulation from Daves interesting Things.

So far with the doors done, has eliminated a fair bit of road, tyre noise (BFG Mud terrain tyres). Still a fair bit of engine, exhaust noise, but will work on this when I do the firewall, transmission tunnel, and floor.

Once the door is apart, starting to put the butyl sound insulation.

Drivers footwell, firewall, transmission tunnel. Have since done the drivers seat box, and under the cubby box. Have to do the front passenger side, and rear of the cabin. The back has roller drawrs, so hoping this will not need to be done. All up about 6 hours work so far. Would be less if I knew what I had to take apart to get to what I want to do.

More to follow as I do the work.

Cheers,

Ken

Update: Finished off the passenger side, and rear. Passenger side made a bit more difference. Doing the rear passenger floor, and under the bench seat has made a big difference. The RAAMmat works very well in stopping the drumming road noise through all the flat pannels in the car. This is added to some thick rubber, and closed cell foam on the floor and transmission tunnel. Have not taken any long trips since I have installed, but on short trips, it has cut out a lot of noise. Should also cut out some heat from the exhaust, and engine. All up cost was about $350 dollars, and in my opinion money well spent. About 7 hours time to do it, but a fair bit was spent on removing the self adhesive closed cell foam I had on the floor. (put it back in on top of the RAAMmatt).
In conclusion:
1. Doors made a big difference.
2. Floors, and transmission tunnel made a bigger difference.
3. Once I remove the air conditioner unit, (I plan to move it to the rear, and make more passenger foot room), I will try and get to the firewall, and put some on it. This should cut some more of the engine rattle.

All up a fantastic car has been made even better, and more comfortable for the use I intend to use it for. Long distance touring, and Serious off road exploring.:D

Nice job. Am part way through doing mine, and have been using the matting that Dave sells. (Used 2.5mm version in the rear under the home made storage, but am going to use the 5mm stuff for the whole floor in the hope it shuts the road noise up). However, the foil stuff you have looks very useful for in the doors and the firewall - where did you get it from in the US, and how much did it cost to ship?

Also, just out of interest, is that factory central locking in the drivers door? Have been meaning to fit a kit to mine for ages....

Jeff,
Here is a link to a web page that I got off this forum.

http://www.sounddeadenershowdown.com/

It has useful info, and I contacted Rick at RAAMatt from there. Shiping was not a hastle, but might be now, as the international shipping for UPS has changed. Just contact them and see. It was about $70 dollars U.S. to ship, and about $270 in product. Took about 6 weeks to arrive. There are other companies that sell similar products, but none that I could find here in Aus.
I have seen a tar/aluminium product (for roofing repairs) that looks similar at Bunnings, but suspect it would melt if subjected to any sort of heat. Did get the 2.5mm heavy vinyl from Dave. Great product, and works well.
As for the automatic locks, they came standard on my car, as it is a 2005 Defender.

Cheers,

Ken

Thanks for that. I think I'll borrow a sound meter and see if I can measure a difference from the before and after too....now to get something ordered. The combination of exhaust, MTR's and me driving it harder soince tweaking the engine has resulted in the noise going up somewhat from when I bought it. :(

Hi Ken, that is what I want to do too. I've been looking for mats, but havn't decided which one to go yet.

Here is some pics what I've done for sound insulation from outside of the car. It made noticable difference + some sort of body protection. Can't tell how much it costs, because I've got offcuts for free :)

See the rubber mat (conveyer rubber) 800x600x10mm under rear passenger floor:

Left and right underfloor space covered too (rubber bolted to rock slider):

I don't worry about stone chips, and very easy to wash after playing in mud.

Cheers,

Hello Ruslan,
Looks good. Any chance of saving some more offcuts in the future for me? I would like to line the wheel wells, and under the floor like you have done. Mount Gambier is only a short drive from Melbourne, and would like to head to the Grampians when it gets warmer.

Cheers,

Ken

Yep, he now can't ship from the US unless by sea crate, so won't do it for just a couple of rolls! Typical. :(

Hello Ken,
I can't promise, but I'll try. I do not have much time today, so will visit them next week and let you know about results.

Or/and PM me when you going to be in our area, I'll take you to that place. There are many sorts off different rubber strips, you will find something for your wheel wells for sure.

Cheers,
Ruslan

UPS is a private sector courier company like Fedex, very quick and very expensive. The changes were with the U.S. Postal Service, the post office, and nothing to do with UPS. As of May 14-07 there is no longer a surface mail service from the USA to Australia, only air-mail. My US sourced range of tools and tooling are going to have substantial price rises when the air-mail stock arrives.

What happens when the water gets in under it and gets hot, then cold, then hot then cold and then starts the good old electrolisis action we know as rust???

Defender floors and doors are prone as they are....

what if you used that stuff that you put on a ute tub ?

After driving my defender around for a few km with no front floor/transmission cover or bonnet, I was amazed at how noisy it was.

A small addition of sound deadening materials should make quite a difference.
