ZircoFlex® GOLD – A Flexible Ceramic Heat Shield Material
ZircoFlex® GOLD is a high performance heatshield material offering exceptional levels of protection against both radiant and conductive heat in a single easy to use product.


ZircoFlex® GOLD is a gold backed aluminium foil that provides maximum levels of heat reflectivity. The material is:
Gold Backed – Delivering 98% heat reflectivity.
Flexible – ZircoFlex® GOLD is easily bent and manipulated to suit different geometries, and can be folded tightly through 180° without damaging the thermal barrier.
Lightweight – ZircoFlex® GOLD weighs only 0.56kg/m².
Extremely Thin – 0.35mm overall, needing minimal space for installation.
Easily Cut – And installed by hand or machine.
Easily Fixed in Place – Using mechanical fasteners or using a high temperature adhesive which is included in each retail pack.
The Benefits
Highly Effective Thermal Barrier – The ceramic pattern on ZircoFlex® creates excellent, proven, thermal barriers. Using the standard BSI heat shield test, ZircoFlex® GOLD is comparable to standard ZircoFlex® I, reducing temperatures by ∼64%. This ensures minimal heat transfer and high levels of protection of the underlying component.
Highly Reflective to Radiant Heat – ZircoFlex® GOLD is highly reflective of infra-red radiation with results better than 98% reflectivity recorded at >600nm. Provides excellent thermal protection from radiant heat.
Ultra Light-Weight – ZircoFlex® GOLD weighs ∼560g/m² therefore adding minimal weight with virtually no effect on the cars weight balance.
Thin and Flexible – ZircoFlex® GOLD is 0.35mm thick and is easily bent and folded to shape.
Attractive Finish – A bright gold finish that is highly visible within the engine compartment, allowing ease of inspection.
Easy to Shape – Can be cut to shape with as simple a tool as scissors, with no further tools required for application. Easily used within the pit garage or at home.

Typical Applications
- Protection of engine bay components from engine and exhaust heat.
- Bodywork protection, e.g. The protection of carbon composite materials from radiant heat damage.
- Reduction of heat soak through footwells, bulkheads, etc.
- Insulation of air intake systems. Reducing heat soak thereby minimising air intake temperatures for maximum engine performance.
