Thermo-Tec Adhesive-Backed Aluminized Heat Barrier 12 in x 24 in — Reflective to 2000°F, Thin Peel-and-Stick

This sheet combines a highly reflective aluminized surface with a woven silica substrate and a temperature-rated adhesive backing to create a compact, easy-to-install thermal shield. It's intended for use where radiant heat could harm painted surfaces, plastics, wiring, hoses, or interior panels. The material is engineered to reflect intense radiant temperatures while the adhesive layer handles continuous direct contact heat up to its rating, enabling neat, permanent installations on flat or curved surfaces.

How does this barrier reduce heat exposure to nearby parts?

The aluminized face reflects a large portion of radiant energy away from the protected component, reducing heat transfer by radiation rather than relying exclusively on insulation thickness. The woven silica core adds structural stability and some thermal resistance, while the adhesive-backed design keeps the barrier in continuous contact with the protected surface for effective heat control.

• Reflective surface withstands radiant temperatures up to 2000°F.
• Adhesive backing manages direct and continuous contact temperatures up to 300°F.
• Woven silica core resists fraying and maintains shape on curves and edges.
• Thin profile makes it suitable where space is limited behind panels or hoses.

Where can I apply the Thermo-Tec 13575 sheet in a vehicle or workshop?

The sheet is versatile for multiple hot-zone applications: firewall patches, underside of hoods, routing shields for hoses and wiring, door cavities exposed to exhaust heat, and localized spot protection for painted surfaces at risk from radiant exposure. It bonds quickly to clean, dry surfaces and can be wrapped around hoses for a tidy finish.

• Firewall and hood insulation to protect paint and trim.
• Hose and wire wraps to prevent heat soak and premature aging.
• Door or panel patches where exhaust or engine heat radiates inward.
• Custom cutouts for brackets, sensors, or accessory mounts.

How durable and easy to install is the adhesive backing?

The pressure-sensitive adhesive is formulated to remain stable under continuous temperatures up to 300°F, offering a permanent bond on metal, composite, and many plastics when surfaces are properly prepared. Installation requires basic surface prep—cleaning and degreasing—followed by firm pressure to set the adhesive; trimming with scissors or a utility knife shapes the sheet to fit tight locations.

• Requires clean, dry surfaces for optimal adhesion.
• Trim-to-fit with standard cutting tools for custom applications.
• Adhesive tolerates continuous direct temperatures up to 300°F.
• Flexible weave allows wrapping around hoses and slight curves without creasing.

Will this product work near exhaust components and extreme radiant heat?

The aluminized face is engineered to reflect radiant heat up to approximately 2000°F, making it suitable as a reflective shield against high-temperature sources. However, the adhesive backing has a lower continuous temperature rating; for direct contact with very high exhaust temperatures, use the barrier as a reflective shield with an air gap or select mechanical fasteners to avoid overstressing the adhesive.

• Reflective side tolerates radiant temperatures up to 2000°F.
• Adhesive-backed side is rated continuous up to 300°F; avoid prolonged direct contact above this.
• Best practice: combine with an air gap or mechanical attachment near extreme heat sources.
• Use on secondary surfaces, trim areas, and hose wraps where adhesive limits are respected.

Who is this for? Thermo-Tec 13575 suits automotive restorers, performance builders, fabricators, and DIYers who need a compact, reflective heat shield that installs quickly and presents a clean appearance. It's ideal when space is tight and a thin, adhesive-backed barrier will protect paint, plastics, wiring, and hoses from damaging radiant heat. If your project involves continuous direct contact with extremely high temperatures, consider using the sheet as a reflective layer with an air gap or mechanical mounting to preserve adhesive performance.
