248: — a special tool that consists of a metal (or plastic) wheel on a handle — is used to press the spline into the frame. The wheel edge is concave, to help it hold the spline and not slip off to the side. Some spline rollers are double-ended and have both convex and concave rollers; the convex roller can be used to seat the spline deeper into the channel without risk of cutting the screen. Driving the spline into the channel tends to tension the screen on the frame, so the installer must avoid pre-tensioning the screen excessively to prevent the frame from becoming warped.
415:. Aluminum is generally available in natural aluminum or in an applied black or charcoal color, which make the screening less visible. Fiberglass is available in light gray as well as charcoal colors, the charcoal again offering better viewing and appearance. Fiberglass is less expensive, and has the advantage of not "denting" when hit or pushed, but it is somewhat more opaque than aluminum. For this reason, dark aluminum allows a better view of windows from the exterior, detracting less than fiberglass from the architectural effect of traditional divided-light window styles.

Less common screen fabrics include copper, brass, stainless steel, and galvanized steel. For coastal locations, corrosion resistance usually requires the use of bronze or synthetic screening fabric.

fiberglass. The fineness of a screen mesh is measured in wires per inch on the warp (length) and the weft or filler (width). An 18×14 mesh has become standard; 16×16 was formerly common and other common sizes are 18×18 and 20×20. For comparison, a typical screen in a clothes dryer has a nylon 23x23 mesh screen.

Some manufacturers offer screening that promise to substantially reduce the visibility of the screening. Several manufacturers offer screens that roll into a pocket when not in use. These are available for casement windows as well as other types of window and door openings.

A window screen prevents insects flying or crawling into a house without obstructing the view or airflow through the window. It is not generally intended to prevent young children from falling out of the window, stop home intruders, or defend against larger animals.
222:. In some regions such as the northern United States and Canada, screens were required to be replaced by glass storm windows in the winter, but now combination storm and screen windows are available, which allow glass and screen panels to slide up and down.
444:
In addition to insect screening, denser screen types that also reduce sunlight and heat gain are available. These offer significant potential energy savings in hot climates. Other manufacturers offer screens designed to filter for pollen and dust.
256:"Wove wire for window screens" are referenced in the American Farmer in 1822. Advertisement for wire window screens also appeared in Boyd's Blue Book in 1836. Two wire window screens were exhibited at Quincy Hall in Boston in 1839.

secured laterally by the tracks of the window. A sliding mechanism allows the screen to be adjusted laterally to fit the width of most windows, which also allows the screen to fit securely within the tracks below the open sash.

Window screens designed specifically to prevent insect entry were not patented in the United States, although by 1900 several patents were awarded for particular innovations related to window screen design. By the 1950s,
