Model T Ford Forum: Forum 2012: Heat shields

For a heat shield under the floor boards over the exhaust, I see some folks use aluminum and I guess leave a gap between it and the wood. Could the Hardy backer used under tile floors be used and attached directly to the floor? I use it for soldering with a propane torch and it stops the heat. We experimented on it with an acetylene torch and it held up quite well with heat and oxygen applied like we were cutting steel and it would not get near that hot over the exhaust.
Cost of a 3x5 sheet is under $10. Find someone who lays tile and uses it and you may get a left over piece free.

I suppose since it is used under tile and bathtubs it would hold up to any water splashed up from underneath. Good idea. Hopefully someone will point out drawbacks, if any.

Why do you need it?

why not wrap the exhaust?

Why not leave the car the way Ford made it?

Asbestos would be period correct. :-)

I know the cement board is heavy so I only wonder if the need is great enough to make the added weight/handling worth the effort to do and live with.

Mine is stock and in winter I love the heat from the floor. The pedal slots are the regulating factor for that, not the boards themselves.

I used it to make a new resistor coil board for an old golf cart about eight years ago. It's still holding up. I remember checking the specs on it but don't remember the exact numbers. As I recall it was to 1100-1200 degrees and that was the reason I used it.

I don't use any heat shield on the Model T's, but have used thick aluminum foil for shield a paneled wall from a stove pipe. We had a wood stove and the pipe was about 1' from the wall. The wall would get too hot to touch and we were afraid it might catch fire so we used aluminum. We glued the aluminum right to the wall. You could actually lay your hand on the aluminum without burning it.

Part way through a day of touring on a hot day, and Teresa has her feet on the dash! Yes, heat through the floor boards is great in winter, but not when it's touching 100 F one the bank thermometer.I put a heat shield under my floor boards and my wife thanked me. I don't care what anybody else says about it not being "like Henry made it". I don't think it really detracts from it being a "T".

Noel, how did you make your shield?

I made one from an old piece of quite thin sheet metal, I'm pretty sure it is not aluminum. I spaced it out from the wood with a couple of washers to have an air gap, just thought that was better than putting it directly on the wood.

I did it because the wood was turning Kingsford colour, as in charcoal! It should also mention I have a dual exhaust manifold.

Correction it is aluminum, checked it with a magnet. Here are some pics.






It was a menu at a restaurant, today they would be made of plastic. I bought a couple of sheets at an antique store while we were on a T tour somewhere, thought it might come in handy some day.

I bought a roll of insulation made for the hot rodders at an auto parts store. It is about 3/16 inch thick, aluminum on one side and insulation on the other, with a sticky coating on the insulation side. Since then, I picked up another roll at an estate sale of an old car buff. I looked and cannot see the make on the roll.

Noel ....
Has the insulation deteriorated at all? Do you know what the insulation is made of .. i.e. temperature rating? If it's hot enough to char wood, then might it melt the insulation?

I would like to bump my article into the fray showing some of what I did about engine heat.
