Window casings are the decorative frames that surround a window. They serve both functional and aesthetic purposes, helping to seal the window and protect it from the elements while also enhancing the overall appearance of a room. Casings can be made from various materials, including wood, vinyl, or composite materials, and come in different styles to match the architecture of a home. In addition to their protective role, window casings can add character to a space. They can be simple and modern or ornate and traditional, depending on the design preferences of the homeowner. Properly installed casings can also improve energy efficiency by reducing drafts around the window, contributing to a more comfortable living environment.
