A window frame is the structure that surrounds and supports a window. It is typically made from materials like wood, vinyl, or aluminum, providing stability and insulation. The frame holds the glass panes in place and can also include features like sills and trim. Properly installed window frames help prevent air and water leaks, contributing to energy efficiency in buildings. In addition to their functional role, window frames can enhance the aesthetic appeal of a home or building. They come in various styles and colors, allowing homeowners to choose designs that complement their architecture. Well-designed frames can also increase the overall value of a property.
