DEI Heat Reflective Tape: Engineered to Tame Extreme Temperatures
When underhood heat becomes the enemy of performance and component longevity, Design Engineering Inc. (DEI) has the answer. Heat reflective tape is one of the most versatile and cost-effective thermal management solutions available, and DEI has spent decades perfecting it. Founded in 1995 with a mission to solve the racing and performance industry's ongoing battle with power-robbing heat, DEI has grown into one of the most trusted names in thermal protection — and their heat reflective tape lineup reflects that depth of expertise.
Two Distinct Tape Technologies for Different Demands
DEI offers two standout product lines in the heat reflective tape category, each engineered for specific thermal challenges:
- Cool Tape™ — A flexible, ultra-lightweight self-adhesive tape made of one mil aluminized material bonded to a woven glass fiber heat-resistant matting. Cool Tape™ is capable of protecting against up to 2000°F of radiant heat while withstanding direct heat up to 400°F. Its strong self-adhesive backing makes it ideal for wrapping wires, cables, hoses, and fuel lines, sealing air boxes, securing panels, and finishing the edges of larger DEI heat shields like Reflect-A-Cool or Floor & Tunnel Shield II.
- Reflect-A-Gold™ — A step up for extreme environments, this tape uses a metalized polyimide laminated glass cloth construction with a high-temperature pressure-sensitive adhesive. Designed specifically for extreme temperature-swing environments, Reflect-A-Gold™ handles up to 800°F and resists UV damage. It is purpose-built to protect firewalls, air boxes, transmission tunnels, and engine components — making it a favorite among performance and racing enthusiasts.
Why DEI Stands Apart in Reflective Tape
What separates DEI's heat reflective tapes from generic alternatives is the combination of materials engineering and application-specific design. Both Cool Tape™ and Reflect-A-Gold™ feature easy peel-and-stick application that won't lift over time — a common failure point with inferior products. The aluminized and metalized surfaces actively reflect radiant heat away from sensitive components rather than simply absorbing it, keeping fuel lines cooler, protecting wiring insulation, and reducing intake air temperatures.
DEI's tapes are available in multiple widths (1-1/2" and 2") and roll lengths (15" and 30"), giving installers the flexibility to tackle everything from a quick wiring loom repair to a comprehensive underhood heat management project. With the majority of DEI products proudly made in the USA and backed by over 30 years of thermal engineering experience, these tapes are built for the street, the track, and everything in between.
Whether you're a weekend wrench-turner protecting a fuel line or a seasoned builder shielding a race car's firewall, DEI's heat reflective tape solutions deliver professional-grade thermal protection that installs in minutes.
