Reducing heat and noise levels.

[Bundalene]

We have been meaning to heat proof and sound proof our other Defender (2006 TD5) for a while now The aim was to reduce the cab heat, mainly by insulating the cubby box area, where I think most heat comes in.


To attach heat proofing material to the underside, we inserted some rivnuts at appropriate spots and inserted 6mm x 50mm screws

Next, cut insulation material and start installing. This is not a sticky backed material, buy has reflective material on both sides. The handbrake drum was removed to get a bit more room

Tape up and secure the material with nuts & washers on the screws.

Insulate under the floor space below your feet

No space under the tunnel cover, so reflective tape will have to do here.

Wrap the exhaust, from the manifold down to the rear of the gearbox

As for sound proofing, this required a lot of templates.


We basically added another layer of sound proofing right across all accessible areas in the cab.

Then put all the original Land Rover matting back over the top

When complete, you cant see much of our efforts, but WOW, what a noise reduction. We will see how the heat reduction goes on our forthcoming trip to the NT


This mod can easily be done to the Puma as well. The job took the best part of 2 days.

I hope it makes the trip more comfortable for you both - obviously you've been spoilt by the luxury of the Puma :D
Have a good trip.

Once again thank you for the post.

Please inform us about the heat reduction as I am very interested to known the result before I start the work on my 110.

What is the insulation material made of ? Could you post please a picture showing the layer the insulation material is made of?

There are some links and more info on this and following pages. This is the same material I used on the Puma. The heat insullation is impervious to moisture and most chemicals. I believe it has a rating of R4

We have just come back from holidays. The heat insullation is extremely effective, no heat transfer around the seat bases or under the cubby box at all.


The outside temperature in the Northern Territory were quite high - in the high 20's and the low 30's

howd you go with the exhaust wrap?

in the past I've found that it picks up water/mud/dust/seeds and promotes rusting of the exhaust and in the event of an oil leak from the engine can act as a hard to extinguish wick.

[Brad110]

I am considering wrapping the exhaust from manifold to gearbox.

What material would you recommend?

[Drover]

I recently installed a de-cat pipe on my 2008 PUMA, the heat difference to the seat boxes and hand brake lever have been an unexpected benefit of the install.

The heat difference is very noticeable !

This can only be contributed to the massive oversize size of the cat and the need to have it so close the floor on the PUMA.

The exhaust wrap held well. We have done over 10,000kms to date with a lot of rough tracks and different type of terrain. I have had a good look and it still appears similar to the day it was put on.

So where can one purchase the Thermotek products ?

[Bundalene]

Give them a call on 1300 727083 to find the nearest supplier. I was able to go down to their factory and discuss our requirements with their techs, they were more than helpful.
