Floor Insulation

[numpty]

I have a complaint from my passenger that her feet get hot from the floor in my Defender (Td5) I assume it's from the exhaust as well as the usual transmission heat buid up.

Does anyone have a fix for this and if so what have you done?

I suggest a search there are a few threads on this.

i posted a project on this about 6 months ago under projects/tutorials. what i didn't do and regret is focus on the aperture where the gear stick passes through into the cabin. it's a source of noise and heat.

while i had great results on the noise front, by and large the heat persists. The best way to address the heat is an external heat shield barrier but that comes with its own problems ie trapping dirt and moisture and access to the fire wall and transmission tunnel.

This was on the floor of a Defer I looked at a while ago.

I made a fairly crude but effective heat shield out of some zincalume flashing material. it's got two layers held together by long pop rivets that also pass through spacers about 6mm long and cut from 1/4" copper tubing. It's screwed to the body above the exhaust. I don't have any pictures at present and it's dark outside, so I'll take some tomorrow if you want. There's also a layer of 10mm, self adhesive, foil backed, aircon ducting foam stuck to the whole of the underside of the body. Excess heat is effectively banished.

I have a mate who runs a business that specialises in heat/noise suppression
materials for industry & I know he has had to solve this problem before.
pm me & I will pass on his details.

Photos would be helpful when you get a chance.

How would you do it? Sounds like a good idea.

Thanks all, I have a few things to chase up now.

Just finished installing fat mat in my 130 , I did the rear seat box and cab wall behind the rear seats last week , it has made quite a difference to being able to hear passengers in the back , today i did the roof front seat box ,firewall and transmission tunnel , big difference at idle was noticed straight away , alot quieter on road as well , I took MLD,s advice and double layered the tunnel as well as sealing as close to the gear leavers as possible making a boot out of the fat mat , heat should be well down along with the road noise
