Description
Product Overview
The WISAUTO Aluminized Fiberglass Heat Shield is engineered to provide superior thermal protection for automotive exhaust systems and related components. Measuring 12 x 24 inches with a thickness of 0.032 inches (0.8 mm), the sheet offers 288 square inches of coverage. Constructed from high‑grade glass fiber fabric coated with an aluminized outer layer, it reflects radiant heat while the fiberglass core absorbs and dissipates residual heat. The sheet includes a pressure‑sensitive adhesive backing, allowing it to be wrapped or laid onto surfaces without additional fasteners, delivering a clean, professional finish.
