Aluminum foil tape is commonly used in HVAC systems for sealing ducts, ensuring they are airtight and leak-free. It prevents energy loss and enhances system efficiency by providing a secure seal. It is often used to seal seams and joints in insulation materials, particularly for thermal and acoustic insulation. Its reflective surface can also help reflect heat and maintain energy efficiency. In the automotive industry, aluminum foil tape is used for heat shielding around exhaust systems, engine parts, and other components exposed to high temperatures. Aluminum foil tape is used in electrical work for shielding cables from EMI and RFI, as well as for grounding purposes. It helps reduce interference in electronic devices and cables.
