Fabric Heat Shields

Our T1000, T101 and T2000 sewn fabric insulation blankets are used to insulate engine parts, exhaust piping and components. In particular, applications which use diesel or gas engines, such as power generation, off highway & on-highway vehicles, and marine propulsion often require insulation blankets to manage the heat that these engines generate. Many material and closure options available.

Foil Heat Shields

Our T3000, 301 and 302 series foil heat shields products encapsulate insulation material between stainless steel or Inconel metal foil skins, or in the case of T302, welded direct to the metal substrate. Skins are typically press formed to provide a precision fit with a mating housing surface. Typical applications include combustor cases, bleed air ducting, engine exhaust ducting, hot section components.

Sheet Metal Shields

T4000 sheet metal insulation cladding systems are designed to survive and perform in the harshest environments, including landfills, methane gas and marine applications. With a unique attachment mechanism and a 16 to 22 gauge shell usable either inside or outside, the total encapsulation achieved is able to withstand impacts, high vibration, chemical and pressure washing and temperatures of 2100°F.
