Aluminized/Silicon Cloth

The Longacre aluminized/silicon cloth is a professional-grade heat barrier designed to protect sensitive components, wiring, and equipment from extreme radiant heat in high-temperature environments. Measuring 58 x 24 inches, this non-asbestos thermal shield is essential for engine bay applications, exhaust line protection, and any setup where heat management directly impacts performance and safety. Whether you're building a racing engine, installing headers, or managing thermal concerns in tight mechanical spaces, this barrier provides reliable protection without the health risks associated with legacy asbestos products.

Constructed from a durable aluminized and silicon-coated fabric composite, this heat barrier reflects and dissipates radiant energy efficiently up to 600 degrees Fahrenheit—a critical threshold for most automotive and powersports applications. The reflective aluminum surface bounces heat away from vulnerable components, while the silicon weave provides structural integrity and flame resistance without brittleness. The non-asbestos formulation meets modern safety standards while maintaining the thermal performance necessary for serious engine builders and professional technicians who require dependable insulation in demanding conditions.

This cloth is ideal for custom fabricators, drag racing teams, street rod builders, and mechanics who need flexible, cut-to-size thermal protection for exhaust manifolds, turbo chargers, fuel lines, and brake systems. Its generous 58-inch length allows multiple applications from a single roll, and the material can be wrapped, draped, or mounted using high-temperature fasteners or adhesive. The lightweight construction (2.16 lbs) makes installation straightforward without adding significant weight to the vehicle, and the non-asbestos composition ensures compliance with workplace safety regulations while delivering professional-grade thermal management.
