Thermo-Tec aluminized heat barrier 12" x 24" adhesive-backed panel — reflective, flexible silica weave

Thermo-Tec 13575 is a 12" x 24" adhesive-backed aluminized heat barrier made from woven silica with a flexible reflective finish for protecting surfaces from radiant heat.

This thin, flexible panel combines a high-reflectivity aluminum surface with a woven silica substrate and a pressure-sensitive adhesive backing to control radiant heat in confined areas. Designed for automotive, marine, HVAC, and industrial applications, it installs quickly and conforms to curved or irregular shapes. The construction separates extreme radiant temperatures from sensitive surfaces while the adhesive layer tolerates continuous contact heat at moderate temperatures.

How does this material reduce heat transfer to nearby components?

The aluminized face reflects a large portion of radiant energy away from the protected surface while the silica weave provides thermal stability and spacing, reducing conduction. Together they lower the thermal load on painted surfaces, plastics, wiring, and hoses without bulky insulation layers.

• Reflective finish sheds radiant heat up to very high temperatures
• Silica weave offers thermal durability and structural support
• Thin profile minimizes added bulk in tight locations
• Adhesive backing ensures continuous contact and effective coverage

Where can I use a 12" x 24" adhesive-backed heat barrier?

This size is practical for spot protection on firewalls, under hoods, around exhaust plumbing and turbocharger plumbing, and on doors or panels near heat sources. It also wraps hoses and lines or trims into shapes for targeted shielding.

• Firewall patches and hood insulation touch points
• Hose and wiring wrap for exhaust or turbo proximity
• Door inner panels near engine or exhaust heat paths
• Custom cut pieces for brackets, clamps, or component covers

How durable is the adhesive and how hot can the material withstand?

The exposed aluminized surface tolerates very high radiant temperatures, while the adhesive layer is specified for direct and continuous contact temperatures up to 300°F (approximately 149°C). This means the barrier maintains adhesion in many engine-bay and equipment applications while the reflective top resists higher transient radiative heat.

• Reflective surface resists radiant temperatures up to very high levels
• Adhesive backing rated for continuous contact to ~300°F
• Woven silica substrate adds mechanical strength and heat resistance
• Flexible construction allows shaping without cracking or delaminating

How easy is it to cut and install for a professional finish?

The sheet cuts cleanly with common hand tools and conforms to curved shapes for a neat installation. The adhesive backing creates a tidy, low-profile bond so wrapped hoses or applied patches appear factory-installed when trimmed properly.

• Cuts with scissors or a utility knife for custom shapes
• Conforms around pipes and tight radii with minimal creasing
• Peel-and-stick application saves time over mechanical fasteners
• Leaves a uniform reflective appearance after trimming

Who is this for: Technicians, builders, fabricators, and DIYers who need a compact, high-reflectivity heat shield for targeted protection will find value in the Thermo-Tec 13575. It suits automotive restorers protecting painted panels, performance tuners shielding hoses and turbo plumbing, marine installers controlling engine compartment heat, and maintenance crews adding thermal protection to equipment. Choose this panel when you need a thin, adhesive-backed reflective barrier that installs quickly and adapts to irregular surfaces without adding significant bulk.
