Heat shield material?

[newsh]

I need to make a new heatshield for the front of the exhaust manifold. Where can I buy the special layered material to do this?

Or has anyone got one of these in good condition for sale? They are not actually that expensive but are apparently not available at the moment.

If you're going to Combe, Merlin motorsport do a layered heatshield material

If you end up hobbying your own heat shield then you may use 2 layers of aluminium sheet metal and thermotec/welding like heat insulation strap between them. I'd use pop rivets to combine the whole.
