HeatShield Thermaflect Shield - Universal Flexible Heat Shield 14" x 20"

This Thermaflect Shield from HeatShield is a universal flexible heat shield that deflects heat away and is rugged enough to be used for almost any radiant heat application.  If used with a 1" air gap between the heat source and Thermaflect Shield along with good airflow, it is capable of reflecting over 90% of radiant heat.

It features a 1/4" thick BioCool* thermal-barrier inner pad sandwiched between heavy-duty foil, bound and sewn together with a stainless steel mesh at the edges. By binding the edges with this mesh, this allows for greater flexibility and a more rugged product overall. It is designed to withstand 594°C continuous radiant heat, and an impressive 260°C when in direct contact.

This shield is intended for wrapping around air boxes, electrical boxes and air conditioning components or to shield radiant heat from catalytic converters, mufflers and DPF, and on the bottom of the floorpans. You can also fasten it with Thermal-Tie, safety wire, screws or rivets. Please note that this product is not to be used directly on the exhaust system.

* BioCool is a non-caustic, non-flammable thermal barrier. It does not cause itching and won’t smoke or smell the first time it is heat-cycled.

Always wear safety glasses, a dust mask and gloves when handling this product.

Caution: This product is electrically conductive. Be sure to insulate any terminals, wires or circuits that may come into contact with this product.

SHIPPING IS FREE* for orders of £60 and over , regardless of the weight of your order.
We've tried to keep all other shipping costs as low as we can.

Carriage starts at just £0.95 (inc VAT) for small items, with our most common courier rate set at £4.99 for orders of 5kg (enough for 5 litres of oil).

  • *Free shipping is available for UK Royal Mail, UPS Access Point™ (click & collect) and standard UK courier services (not express / priority / islands).
  • Courier surcharges mean we are unable to offer free "to the door" courier shipping from us in Cornwall up to Highlands / Grampian in Scotland - and because we send a lot of liquids, not every courier option is available to us. UPS Access Point™ (click & collect) is available as a free shipping option across Scotland, Wales and England, wherever there is a UPS Access Point™ Location.
  • Carriage charges are based on weight - please see our table of carriage costs for full details (although adding an item to your cart and viewing the calculated carriage is often easier!).
