The charcoal is much less visible and should be preferred where the view through the screens as well as the external appearance of the windows are important considerations. Aluminum is generally available in natural aluminum or in an applied charcoal color. Types of Screening Fabric – The most common materials used for insect screening material are aluminum and fiberglass. Because of corrosion problems, metal screening fabrics other than aluminum should not be used in aluminum frames. The screening fabric needs to be stretched tightly before nailing, but not so tightly as to deform the fabric.

A small wooden molding is then nailed over the ragged edge. When installed using wooden frames, the screen fabric is tacked or stapled onto the frame. Try to find a hanger with a wire thickness just a bit smaller then the cord, and use a rounded corner to press the rubber back into its groove. If the wheel is not available a good substitute is a medium thickness wire clothes hanger. The wheel has an indentation in its edge to help it catch the cord and not slip off. A special tool that looks like a wheel on a handle (called a spline roller) is used to press the cord into the frame. Installation – For screens installed using aluminum frames, the window screen is typically cut larger then the frame, laid over it and a rubber cord (called a spline) is pressed over the screen into a special groove (called a spline channel) in the frame, the screen is then trimmed. Screens in North America were traditionally replaced with glass “storm windows” in cold climates to insulate the window during the winter, but frames combining both storm and screen panels have become the most common type of screen currently used in cold climates. Most houses in North America have screens on all operable windows, which are most useful in areas that have large mosquito populations. Its primary purpose is to keep insects, leaves, birds, and animals from entering a building or a screened structure such as a porch, while permitting fresh air-flow. Window Screen – A “window screen,” “insect screen,” or “fly screen” is a metal wire, fiberglass, or other synthetic fiber mesh, stretched in a frame of wood or metal, designed to cover the opening of an open window.
