Heat protection under-floor

[Thomas ZR-1]

This winter I make a 368 from my 350 LT5. The engine is out and I`m still working on the engine block but last weekend I spend some time under the car for lowering the temperature inside. I sticked some heat protection foil after cleaning the under-floor. This foil is heat resistant until 600 °C (around 1100 F). It`s an aluminum metallized glass fiber material that we use in our company at the engine test benches for many years now. It was a little challenge without a car lift…;)

Can you pass along a brand name, spec & performance numbers on the insulating material you are using? That is very interesting.

I think it`s a prodcut from the US and I wonder it`s up to 2000 F.

Is it plyable like Dynamat, or rigid like sheet metal?

It`s quite flexible. You can cut it with a normal paper-shears or a cutter. It`s easy to install if the transmission is out of the car. The has to be absolutely clean...no more undersealant or wax.

A similar heat shield was factory installed in my 64 Corvette.
I think the C3's had it also.
I'm surprised it didn't carry over to the C4's.
