Window frames that are placed on the sides of the window to support the glazing are called window jambs. These structures can be made of various materials, such as wood, vinyl, aluminum, or fiberglass, and are essential components of a window system. Window jambs help to hold the glass in place, provide stability to the window, and prevent drafts and moisture from entering the interior of a building.
Window jambs can also be customized to fit different window shapes and sizes, and they come in different styles and designs to complement the aesthetic of the building. Some window jambs have a sloped design to help with water drainage, while others have integrated insulation to improve energy efficiency.
In addition to window jambs, there are other components that make up a window frame, such as the head, sill, and muntins. The head is the horizontal piece at the top of the window frame, the sill is the horizontal piece at the bottom, and the muntins are the dividers that separate the individual panes of glass in a window.
Overall, window jambs are an important part of a window system that provides structural support and enhances the overall functionality and appearance of a window.
