Thread: Insulation options that are waterproof?

I have treated mine with closed cell foam, the footwells, gearbox tunnel, seat bases and cargo area are now covered.
The result is amazing, I can drive while wearing shorts. The noise has also been dramaticaly reduced.

Will have to wait for winter to see if the foam will absorb water.

Don't know if you've had a look at the stuff but it's made from recycled tyres in Australia I think you'd find a lot more toxic materials in any new vehicle to start with.
No I wouldn't wrap it around a exhaust pipe but on the floor and under the seats it works really well stops a lot of vibration noise as it's fairly heavy 9kg sq metre

The best way to reduce heat transfer from an exhaust is to have it ceramic coated inside and outside. It's quite amazing how effective it is, but a bit of a waste on standard pipework. Doesn't do so much for noise transfer, but maybe a little as it smooths the internal surface so there's not so much echoing.

Usually done on extractors.

Not perentie and not something you'd expect on a Series III military:

It won't on aluminised tube, but will with black steel.
