What are the differences between aluminum foil facing and other types of foil?

Aluminum foil facing is characterized by its aluminum layer, which provides excellent heat and light reflection, making it ideal for insulation and cooking applications. It's also resistant to corrosion and has a shiny finish. In contrast, other types of foils like Mylar (polyester) are more flexible and tear-resistant, used in various industrial applications. Copper foil is used for electronics due to its high conductivity, while gold foil is valued for its decorative properties. Each type of foil has unique properties that make it suitable for specific uses, with aluminum foil facing being particularly known for its thermal and reflective qualities.
