In a vehicle, a window channel is the rubber seal that acts as a guide for the window as it is opened or closed. In a house, the window channels are the metal or vinyl tracks in which the window slides back and forth. In essence, the window channel channels the window into position. The window channel is stationary and receives wear and tear from the continual friction of the window.
Flex window channels are often used in marine, automotive, aeronautic, and RV industries. Shaped like a long, narrow tube that has a slit down the middle to create its U shape, they are pliant and accommodate a tightly fitting radius. Window channel framing for a building is typically a rigid track made of metal or vinyl. Window channels come in all shapes and sizes. In vehicles, the vehicle style will determine which window channel to be used.
Window channels provide insulation around the window, preventing outside air or sounds from entering the room or vehicle. Properly fitted and conditioned window channels in a vehicle contribute to a quieter drive when on the highway. In a home, well fitted and insulated window channels can help to lower energy costs by keeping external temperatures or moisture from entering the room.
Window channels can be made from a variety of materials including wood, metal, rubber, aluminum, and vinyl. The shape of the window channel varies depending on what type of a window it is applied to. In a house window, the window channel may be on narrow tracks, while a window channel in a vehicle might be a long, narrow strip that is bent into a shape like a distorted W.
