Window frames are the structures that hold the glass panes of a window in place. They are typically made from materials like wood, vinyl, aluminum, or fiberglass. The frame provides support and insulation, helping to keep the indoor environment comfortable and energy-efficient. In addition to their functional role, window frames can also enhance the aesthetic appeal of a building. They come in various styles and colors, allowing homeowners to choose designs that complement their home's architecture. Proper maintenance of window frames is essential to prevent issues like rot or rust, ensuring longevity and performance.
