Window film is not typically permanent. Most window films are designed to be semi-permanent, meaning they can adhere securely to glass for many years but can also be removed without causing damage to the window. They are commonly used residential window film for purposes such as reducing glare, enhancing privacy, blocking UV rays, or adding decorative elements. While high-quality films are durable and can last over a decade with proper care, they can be peeled off using heat and adhesive removers if needed. This makes them a flexible solution for both homeowners and renters looking to improve their windows without committing to permanent changes.
