12" x 24" Aluminized Heat Shield Thermal Barrier - 2000°F High-Temperature Self-Adhesive Reflective Material Sheet, Fiberglass Sheet for Automotive Firewall, Car Hood, Floor Pan & Kitchen Cabinet Wall — Open-Box, 11% Off

【95% RADIANT HEAT REFLECTION】 – Engineered with a professional-grade woven fiberglass insulation core paired with a highly reflective polished aluminum foil face. It continuously repels radiant temperatures up to 1200°F (648°C) and handles brief, intermittent thermal spikes up to 2000°F. Protects nearby automotive paint, clear coats, and sensitive plastic components from warp and heat degradation. 【SELF-ADHESIVE HEAT SHIELD AUTOMOTIVE】– Features an integrated, pressure-sensitive high-tack backing that eliminates the need for separate sprays or contact cement. The adhesive layer safely sustains continuous surface temperatures up to 400°F (204°C). For maximum adhesion, simply clean the target surface thoroughly of dust and oils before performing a firm, peel-and-stick application. 【ULTRA-FLEXIBLE & EASY TO SHAPE】 – At just 0.8mm thick, this lightweight composite sheet cuts effortlessly with standard household utility scissors or shears. The flexible woven structure contours easily around complex, irregular surfaces and sharp bends, making it incredibly easy to mold tightly into cramped areas like transmission tunnels, motorcycle fairings, and inner body panels. 【AUTOMOTIVE & HOUSEHOLD VERSATILITY】 – Designed to safeguard surfaces across multiple environments. While optimized for automotive firewalls, floor pans, battery boxes, and fuel cells, this non-flammable thermal barrier sheet is perfectly sized to protect wooden kitchen cabinets adjacent to slide-in stoves, apartment wall spaces near ovens, or internal panels on outdoor barbecue smokers. 【OIL, FLUID & WEATHER RESISTANT】 – Built to withstand harsh operating environments. The non-corrosive aluminum surface completely resists degradation from water, engine oil, road salt, and fuel splashes. Simply wipe down the surface to maintain maximum thermal reflectivity and operational lifespan, keeping your underlying components running cool year after year.

Advanced Radiant Heat Protection for High-Stressor Environments

 

Whether you are looking to insulate a tight transmission tunnel, protect sensitive electronics from engine bay heat soak, or prevent a kitchen cabinet wall from scorching due to a high-output cooking range, our 12" x 24" Aluminized Self-Adhesive Heat Shield Mat offers a reliable, low-profile defense.

 

By combining a highly polished aluminum foil reflection layer with a dense woven fiberglass backing, this composite sheet acts as an incredibly efficient barrier against destructive radiant heat transfer.

Common Applications & Surface Compatibility

 

1. Automotive & Powersports: Perfect for custom applications across vehicle firewalls, under-hood insulation patches, airbox liners, fuel lines, floor pans, under-seat panels, and motorcycle fairings.

2. Home & Kitchen Utility: Ideal for creating non-flammable thermal boundaries. Place it directly on wooden cabinet side walls next to slide-in ovens, stove surrounds, or use as a defensive layer for custom appliance installations.

 

Installation Instructions: Clean the target surface completely, ensuring it is free of dust, grease, moisture, and rust. Measure the area and cut the mat to your desired shape using standard scissors. Peel back the protective paper release liner, align carefully, and apply firm, even pressure across the entire surface to activate the high-tack bond.
