Compact Thermal Control: DEI Floor and Tunnel Shield II

The DEI Floor and Tunnel Shield II (21in x 48in) is the perfect size for targeted heat management in your vehicle. Whether you are insulating a transmission tunnel, a specific firewall section, or floor pans, this 7 sq ft sheet offers the same high-performance thermal protection as our larger kits, wrapped in a professional black finish.

Why Choose Floor and Tunnel Shield II?

  • High-Temp Resilience: Rated to withstand up to 1750°F on the aluminum face.
  • Durable Adhesive: High-temp pressure-sensitive backing that holds strong past 450°F.
  • Flexible & Thin: Only 3/16 inch thick, allowing for easy installation in cramped chassis areas.
  • Weather Resistant: The adhesive is unaffected by wind, water, or environmental exposure.
  • Versatile Use: Ideal for protecting sensitive electronics, fuel lines, or interior carpets from exhaust heat.

This shield combines an embossed 10 mil aluminum surface with a 1/8 inch composite glass-fiber core to deliver maximum thermal resistance. The flexible nature of the material allows it to be cut and shaped to fit virtually any contour, ensuring a perfect seal against heat transfer. Stop heat soak before it starts and keep your cabin comfortable with this premium insulation from GGCRACING.
