Heat shield material

[BMK]

Hi all just wondering if anyone has found a good quality heat shield material.




I have seen some good aluminium finished material but it is small sizes.

Need at least 600mm x 500mm sizes.

I want to also send it to a trimmer to stitch the edges..

Bernie, I put my son on tho this problem when I was looking. He is an engineers specialising in acoustic and thermal insulation. Came up with: http://rmindustries.com.au/index.php?p=1_1

I bought some from them and it has very impressive specifications.

This is the product I am currently using on the 2 cars I am working on. Check it out.

Is that product for in cabin or on the outside (underside) of the car?

Merv, that E-Therm stuff seems to be designed for housing construction - typically not in the range of engine bay temperatures! Which of their product(s) did you find to be suitable? I do like the idea of using a locally supplied product!

Sambo,

See: http://rmindustries.com.au/index.php?p=1_10 E Glass Aluminised Fabric EWFA 1150100. My son says it has a heat retardant factor of almost 400 degrees.

As merv has pointed out, the best stuff is aluminiumised cloth material. We used that on our Harrison Cobra for engine bay. I've seen it used on the underneath side of rear clips on GT40s. On GT40s it's been edged.

High-temp silicone works well to attach it.

So you literally silicone that stuff to your firewall or transmission tunnel? Is there another way to mount it so you're not sealing all the brake and fuel lines underneath? It would be good to shield them, I'm just not sure I want it to be so permanent.

Paul, with silicone you can still pull it back off. That's the beauty of silicone, you can still remove stuff.

Although I don't imagine you would normally have to remove it, only if you need to repair something underneath.

Silicone is quick and easy, plus you can form the heatsheild material around fuel, brake lines etc.

Ok thanks Craig. When bonding the fibreglass matting how much would you apply? Eg, Run a continuous bead to seal around the edges and then how much coverage in between? Or completely coat the surface?

[400TT]

I've never coated the entire surface, now that would be harder to remove. Haven't seen a need to.

Just enough to provide enough support, you could do a W pattern 50-100mm between the vertical strokes. On upside down surfaces you would use a tighter pattern, on vertical surfaces you would use bigger gaps. And run around the edge as mentioned. I hope that makes sense.

[sambo]

Yep, thanks again mate.

[stephen low]

I'm presuming this style of silcone aplication would make the surfaces look a little blah in terms of finish though? It is stuck on after painting no?

Cheers

Slowy, in my case it will be applied to the underside of the trans tunnel and firewall (which is black powder coated) then the heat shield material placed on top. So all you'd see is the aluminium outer layer, as per the photos on Snakebite.

Thanks for the info guys.

This is for external use. I am covering the inside of the transmission tunnel, outside of foot boxes and all of the cockpit sheetmetal floors. The edges are being finished off with high temp foil tape.

Bernie,

Next time your in Melbourne go to Meridian Motor sport in Moorabbin.
They stock a product that is about 3mm thick , it has an outer layer of aluminum heat sheild then a layer of material in the middle that stops the heat transfer then a layer of glue. So you can just stick straight to what ever surface you want. It comes in a roll 900mm x 500mm. I have used it under floor and on some sections of the firewall.

Rod,

Thanks will send you a PM for more details.

Thanks all.

Six years later, I thought I'd drag this one up after the recent discussion about heat shielding in another thread. Meridian Motorsport (mentioned above) was bought out by Motorsport Connections a few years ago. They carry a range of heat shielding options including aluminized tape. I'm hoping to get down there on Saturday morning.

Bernie which option did you go with in the end - and how effective?

Google "Pyrogel". We use it at work, and it is as good as they claim it is. Fantastic insulating qualities and thin. It can handle high heat and is hydrophobic.
