Aluminum foil tape is a high-performance adhesive tape made of a thin layer of aluminum foil with a strong adhesive backing. It is highly resistant to moisture, chemicals, and high temperatures, making it ideal for sealing, insulating, and protecting surfaces in HVAC, construction, and automotive applications. Its reflective properties also make it useful for enhancing energy efficiency by reflecting heat. Aluminum foil tape is easy to apply and can conform to irregular surfaces, ensuring a tight seal.
