ZircoFlex® FORM – Innovative Structural Heat Shield

It is now possible to create structural heat shields thanks to Zircotec’s heat shield, ZircoFlex® FORM.

This rigid, dimpled stainless steel sheet heat shield, combines Zircotec’s proven ceramic coating protection together with the strength and ability to form structures such as heat shields, boxes and bulkheads.

Thanks to it’s ability to solve multiple heat issues, including both reflective and conductive heat sources with gold and black surface treatments, ZircoFlex® FORM delivers a compelling mix of strength, weight, structure and heat resistance.

There is a yellow gold finish on the one to increase reflectivity and a proprietary metallic  black coating on the other.

  • Effective protection of engine bay components, bodywork and vulnerable electrics from engine and exhaust heat.

  • Reduced heat soak to the cabin to reduce reliance on heavy heat insulation materials and improve passenger comfort.

  • Fuel tank protection that is easily fitted to complex structures with sharp bend radiua and where there is a minimal package space.

  • High performance with minimal weight and thickness, to help meet stringent weight and efficiency targets. ZircoFlex® I only weighs 0.46kg/m2 with a thickness of just 0.25mm.

  • Ease of fitment line-side, with a thin aluminium-backed and ceramic foil that is easily cut and folded to shape, by hand or machine. The metal construction allows the use of mechanical fasteners.

  • A guaranteed supply line for high-volume orders, with a proven track record supplying the worldwide motorsport industry.

  • Thermal insulation of silencer and catalyst units to protect bodywork, hydraulics and other vulnerable components.

  • Ready to use – avoids lengthy design processes, which is particularly beneficial for testing and prototyping purposes.

  • Structural rigidity of ZircoFlex® FORM can be an advantage in a wide range of OEM applications. It offers a unique combination of high strength, low weight and high heat resistance.


  • Core of embossed (type 304) stainless steel sandwich between two layers of Zircotec’s proprietary ThermoHold® based ceramic thermal barrier material.
  • Material thickness: 0.8mm thick.
  • Product thickness: 1.6mm thick.
  • Weight: 2.9Kg/m2
  • Thermal conductivity: ~0.3 W/mº K at 200ºC 1
  • Temperature ceiling: Tested to 900ºC (hot side temperature).

1 Tests based on guarded hot plate method in accordance with BS874 Pt 2 (1986)
