This aluminium coated fibreglass sheeting provides a great heat barrier for exhaust tunnels, bulkheads and any other flat surfaces you want to heatproof.
It's self adhesive and easy to cut to shape.
The adhesive is rated to 180 deg C, but the sheeting itself can cope with up to 600deg C, so more than enough for most popular applications.

We've used in it Phil's S14a to coat the custom exhaust tunnel and we're very happy with the results

This sheeting comes on a 1m wide roll and is priced in 1m lengths.
