Evening all.

I'm about to apply some of the heatshield material (aluminium foil with fibreglass backing) to a couple of panels and pipes on my car, and I was wondering waht methods people have used to affix it?

On a panel, I'm thinking about trying a contach adhesive, with a few mechanical fixings in the corners (rivets and washers probably to spread the clamping area). I'm also going to wrap it round some pipes to try and reduce the heat emitted from them (rad pipes going down the tunnel near my legs!), and I was thinking about using tiewraps.

Anyone got any wonder methods of affixing the stuff?

Also, What is the best way round to apply it? On panels, I was going to fix it down with the shiny side facing outwards (to refelct heat, and any that does get past the aluminium is insulated by the fibreglass).

But when wrapped around a rad pipe, would it be best to have the shiny side touching the pipe, and the fibreglass side on the outside? I think this might be the best way to arrange it, but I'm not sure if having the aluminium surface touching the rad pipe will ruin it's heat reflecting ability, as the heat will just conduct through where it touches.

Which panels do you intend to stick the stuff too?

Pat...

They are going to be stuck down to the rear bulkhead on my car (Sylva Mojo). It's a mid engine, so the exahust manifold and down pipe is really close to the rear bulkhead, so I thought that using some heatshield there would stop the heat transferring through to the cockpit (specifically the drivers seat back!)

As this panel is inclined at about 70 degrees (ish) I'm reluctant to rely on just adhesive, hence wanting use somekind of mechanical fixing as well (eg rivets and washers, or possible bolts)

If the insulation has a foil layer, then the foil should face the heat source. There is a version specifically for wrapping pipes etc. It's best fixed with the metal tie wraps. Nylon cable ties could melt depending on the surrounding heat.
I use the foil faced stuff on the engine side of the bulkheads on my mid-engined cars. It keeps the exhaust from melting the seat covers! Thixotropic contact cement is flamable at -30 degrees C, so be careful with it. Be aware that it becomes almost fluid with even mild heat, so make sure your insulation is good quality.
Your local auto paint store should be able to sell you the proper stuff for afixing sound dampening pads etc.

I have this stuff to stop the engine cooking my back in my grasser.

I just fixed it on using rivets with washers made from pieces holesawed (the bits you normally discard) from 1.2mm ally sheet.

We use this stuff in my factory. The supplier also does a heat resistant sticky foil tape, for sealing joints etc, that makes a very nice job. It's like duct tape, but with the same shiney finish as the wool backing. We also use it to stick heating element wires to tanks, under insulation, so it's REALLY heat resistant.

Maybe you can find some locally, as it's a long way for me to sort you out with a roll from here
