Zircoflex Gold Heat Shield Material

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.
