DEI 42” x 48” Floor And Tunnel Shield Heat Barrier Sheet

Keep the heat away from vulnerable areas in your classic Chevy Camaro, Chevelle, or El Camino with DEI’s 42” x 48” floor and tunnel shield heat barrier sheet (50503). This premium heat shield is constructed with a dimpled 10 mil aluminum exterior bonded to a 1/8″ composite glass fiber core, creating a 3/16″ thick barrier that reflects and insulates against extreme temperatures. The material is rated to handle up to 1750 °F total heat exposure and up to 450 °F on the adhesive side, making it ideal for shielding floorboards, transmission tunnels, fuel cells, firewalls, and other heat susceptible zones.

Features and Benefits:
- Withstands up to 1750 °F total heat 
- Adhesive side rated 450 °F 
- 3/16″ thick with glass fiber core 
- Dimpled 10 mil aluminum face reflects radiant heat to keep it from penetrating

Despite its thermal toughness, the sheet is easy to work with. Cut it to shape for a custom fit on surfaces like aluminum, steel, plastic, or carbon fiber. It helps protect painted body parts and engine compartments, blocks radiant heat from headers and exhaust plumbing, and even guards against road debris. At 42″ x 48″, this sheet covers a large area and can be used in multiple locations on your build.
