Product Description
Window screen, insect screen or bug 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. Its primary purpose is to keep insects, leafs, debris, birds, and other animals from entering a building or a screened structure such as a porch, while permitting fresh air-flow.
The most common materials used for insect screening material are aluminum and fiberglass. Aluminum is generally available in natural aluminium or in an applied charcoal color.
Fiberglass is less expensive, and has the advantage of not "denting" when hit or pushed.
