Window films are thin layers of material applied to the interior or exterior of glass surfaces. They can serve various purposes, such as reducing heat and glare from the sun, enhancing privacy, and blocking harmful ultraviolet (UV) rays. These films come in different types, including tinted, reflective, and decorative options, allowing users to choose based on their needs. In addition to improving comfort and aesthetics, window films can also contribute to energy efficiency in buildings. By regulating indoor temperatures, they can help reduce reliance on heating and cooling systems, potentially lowering energy bills. Many commercial and residential properties use window films for these benefits.
