Window screen

A fly screen is a device that is placed in front of a window or a door in order to prevent the intrusion of insects such as flies and mosquitoes in a room.

An insect screen is made similar to a mosquito net made ​​of fine fabric or wire mesh with a mesh size of about one millimeter, on the one hand through, but on the other hand, letting in insects enough light and air. Lately are also translucent nonwoven fabrics on the market, which are on the one hand preventing the penetration of allergenic pollen into the room, on the other hand also prevent insects for this purpose. Professional Fly screens are made of plastic-coated fiberglass fabric with a mesh size of about 1.4 by 1.2 millimeters. Glass fiber fabric is extremely weather resistant and can remain permanently at the window.

Simple fly screens are fixed with self-adhesive Velcro closures between the window and frame. For framed fly screen contrast suspensions are used, which are attached to the window. With their help it is possible to unfold or unmount these frames separately. Since hardly stay in the cold season insects outdoors, this is especially useful in winter to prevent the weathering.
