Heat insulation for cabin

I used to have a diesel Maverick. Don't recall any probs with heat thru floor.
Fixing a sheet of thin ally or similar above the exhaust, but separated from the floor; ie, with a spacing, should reduce the radiant heat transfer.

I had a similar problem on the passenger side of my GU Ute with a high heat transfer through the floor. I had an exhaust lagging blanket made and fitted to the section of exhaust in this area and fixed the problem.

The blanket is as used on exhausts in the marine industry and heavy machinery (like Patrols). Make sure if you do this order it eye lugs sewn in so that you can secure it with stainless steel tie wire.

good news that covering the heat source does actually work. I guess the tape or blanket is still doing the same trick.

Hi there.
I've used a couple of sheets of roofing sisalation, the material that has a shiny reflective side and a blue side. Place the shiny side against the heat source against the floor pan, so blue side up , then replace your normal flooring.

Be careful wrapping the exhaust because depending on where you live and use the vehicle it may rust the exhaust out.
As has been suggested the best way is to stop the radiant heat hitting the floor with heat shields or purpose built insulation like Dynamat stuck to the underside of the floor.
I then put the cheap closed cell foam sleeping mats between the floor and the vinyl floormats, stops the heat doesn't hold moisture and also drops the sound level down. I stick it to the transmission hump and just lay it on the floor in the footwells, works well.
You can also use interior Dynamat but it is expensive.

all great feedback, thanks. Must admit I didn't think of the rust so maybe a floor shield is the better way to go.

A lot of interior heat comes from the gearbox especially when towing on long trips. The heat can still be felt 2 hours after completion of the journey. If exhaust would cool off much quicker.
A good oil may help.

Hi Gossy

The exhaust tape is the place to start with that problem , its important to hit it at the soucre.

I found it tricky and time consuming to install though and ended up using aluminium wire to hold it in place.

I still went further by placing alumium flashing over the passenger side firewall and spacing it off 1cm , held in place mostly by bits of wire around various pipes etc.

Mine got so hot (because of aftermarket exhaust) that it melted the radio antenna coax that was inside the car but directly touched the firewall - (Nissan replaced the car radio twice - thinking it was faulty - before I diagnosed that I caused the problem with different exhaust)

for my update see thread 67371

cheers,
