Bongo Fury

Guys,

Have searched the forum but didn't find any specific topics?

Has anyone taken the time to soundproof/insulate the bongo? I've been looking at Dynamat etc as I find it quite noisy on the motorway.

Has anyone done it? Would you recommend a specific product?

A lot of people (on other motor forums) use roof flashing which also seems to work but I'd imagine throws more weight onto a lump that already struggles with mpg

Whats your thoughts?
Thanks in advance

Been done before - surprised a search didn't throw up old posts. Try some other keywords (did someone try wool?)

Foam Camping mat beds are light
Make sure all holes are filled covered
I've not put the cover back on to were the jack is stored at the moment and the road noise that is coming through there as loud
I did my old land rover with rubber/foam mating on the floor the difference was amazing I could hear the radio

I used dense foam sheets cut to shape inside the rear which made a slight difference, but it's the floor, wheelarches and around the engine where you'd have to put the effort if you'd really want to make a difference.

Someone on the forum used Rockwool type insulation in the rear and now finds its too warm especially when on the continent.

Hi,

I did mine with some of the self adhesive bitumen pads faced with thick metal foil that came from Fleabay. I stuck it on the inside of all the metal outer panels. The sliding and rear doors are not that easy.
These have the effect of increasing the mass of the outer panels, which tend to resonate like a drumskin.
It definitely became quieter and the stereo sounded better.

What also helped was having it waxoyled, which helped stop the floor resonating.

Also check that the front seat engine hatch seals are in good condition and if necessary tweak the clips that hold the seats down.

I can endorse the recommendation of bitumen. It really works!
You need to cut the sheets to size; they are self-adhesive, and I found that with a hair dryer you can mould them to the contours of the inside of the bodywork (I think this would be especially important in our cold winter weather). The doors are easiest to do, because the door card is so easy to remove. Do be careful about getting in behind the clear plastic with the sticky edge: that adhesive ticks to everything, and is hard to get off clothes, etc.

I also sandwiched adhesive backed acoustic insulation foam between the door card and the clear plastic.

I bought mine from Car Insulation UK: http://www.carinsulation.co.uk/

Now the doors (which are heavier owing to the bitumen) shut with a confident 'clunk', and without reverberation. The stereo sounds better as well (I put new speakers in at the same time as doing the insulation).

A great advantage of bitumen is that you don't need to worry about moisture making the insulation wet and rotten. This is particularly important in the doors, with the electric windows going up and down.

Thanks for the info guys.

This workshop flooring is a great soundproofer
This is what I used in my Landy and it worked
Also has a smart looking finish so it could be used as final top layer
Would look good as a conversion floor

I've used a wool insulation (loft insulation from B&Q) actually a 50/50% mix of wool and synthetic, giving the best of both. Quality breathable insulation that does not trap condensation. Yes its lovely and toasty.

I've done a bit

the talkaudio forum has a good section on sound proofing, it's worth popping over there and having a read
