These shields are constructed with a sheet of 24 gauge or thicker sheet metal or 1 2 or thicker cement board with 1 of air space behind the shield and around the perimeter to allow free air flow.
By placing this sheet of metal around the heat source it will reflect back the thermal radiation created by the heat source and block much of the thermal convection.
The profile of this heat shield makes it an excellent solution for those low clearance areas.
Comprised of two layers of a lightweight embossed 309 or 316 stainless steel with a sandwiched layer of insulating ceramic non woven.
Inferno shields are flexible enough to bend around a pipe air box oil pan or to line a transmission tunnel.
Embossed metal products are designed for forming into heat shields using production tooling or hand fabrication.
Grommets or d rings are strategically placed around the perimeter of the shield for ease of installation.
Individually sold sheets can be the right solution for you to build a custom formed heat shield made exactly for your application that will provide performance to match even the best production designs.
