Thermo-Tec 13575 Adhesive Backed Aluminized Heat Barrier (12″ x 48″)
Heat Shielding Duo. This product comprises two 12″ x 24″ sheets, providing extended coverage for larger installations while maintaining a uniform aluminized finish.
Durable and Reflective. The silica-based barrier with aluminized surface offers high reflectivity and robust radiant heat resistance up to 2000°F.
Buying Guide: Key Considerations for Aluminized, Adhesive-Backed Heat Barriers
Temperature rating and reflectivity are the core performance metrics. Look for barriers rated to withstand at least 2000°F radiant heat, with reflectivity around 95% or higher to minimize heat transfer.
Backing and installation. Adhesive-backed sheets and blankets simplify mounting on irregular curves, hoses, panels, or engine bays. Check cure strength and heat resistance of the adhesive itself, especially in vibration-prone or oily environments.
Material composition. Most effective options use woven silica with an aluminized finish. This combination provides flexibility, durability, and strong thermal reflection in high-heat scenarios.
Size and trimability. Consider the surface area to shield and whether you need blankets, sleeves, or mats. The ability to trim sheets or sheets to custom shapes helps achieve a snug fit with neat results.
Thickness and weight. Thicker barriers can provide better protection but may be harder to contour. Typical thickness around 0.032″ (0.8 mm) offers a balance of rigidity and conformability.
Versatility. A single product that tolerates a range of temperatures and can shield various substrates—painted surfaces, plastics, hoses, and metal components—adds value for multiple projects.
