The very first insect screens were manufactured out of metal, so well begin with metal screen. Generally manufactured out of aluminum, metal screen is a more traditional choice of screen material. It is very strong, making it ideal for geographical areas with insects such as grasshoppers that could pose a risk to eating through screens. Traditionally, metal screen delivers a more visually appealing
experience when looking through them. Other metal screens are made from bronze, stainless and galvanized steel wire.
Fiberglass screening began being manufactured in the late s, and was developed for its forgiving nature. Fiberglass, coated with a vinyl protective layer, offers a durable, longer-lasting option in coastal climates, since it is not susceptible to corrosion. Over time, fiberglass screen has become a popular option for pool enclosures and patios. Generally, fiberglass screen is only available in shades of charcoal or gray.
In the early s polyester fabrics were first produced by Phifer for outdoor furniture applications in our Phifertex® product line. Its strong, durable and weather resistant features in any outdoor application led to the development of other woven polyester products such as PetScreen®, TuffScreen® and SunTex® exterior sun shading fabrics.
While all three types of screen weather well and offer clear views, there are certain characteristics of each screen that make them more preferable in certain applications.
Metal screen, while sturdy, is also not forgiving, meaning that if pets, people or other object impact the screen, it will dent permanently. The fact that metal screen isnt forgiving, also makes it difficult to install in DIY projects. Theres a specific process that must be followed when installing metal screen, and most experts suggest hiring a professional to do the job. One more characteristic to keep in mind, is
Bronze Screen
that metal screen generally comes in maximum widths of 60 to 72 inches. Therefore, if youre looking for screen large enough to cover a wide opening space such as in pool cages, the 6-foot maximum width would not be ideal for projects with wide expanse requirements.
Fiberglass, unlike metal screen, is very forgiving, and can withstand the hustle and bustle of people and pets and accidental bump-ins. This forgiving nature is also a great quality for DIY installs. So, if youre wanting to screen in your back porch one weekend, this material is your better bet. The width range for fiberglass screen is vast, and can be as wide as 132, making it a great option for larger installs such as
18x14 Fiberglass
pool and patio enclosures. Fiberglass is also more cost effective than aluminum.
However, fiberglass screen can have its setbacks as well, with fewer colors available and a greater vulnerability to damage from insects such as grasshoppers.
The primary difference with polyester screening products such as Phifer PetScreen® is not only the different core yarn but how it is coated with the protective vinyl. While metal screens are painted after weaving and fiberglass yarns are coated with a liquid vinyl prior to weaving, polyester yarns are vinyl coated in an extrusion process which places more vinyl on the yarn when compared with
SunTex 80
liquid coating. The result is the ability to make a larger diameter and softer coated yarn. The larger polyester yarns are woven in all SunTex® sun shading fabrics and many popular pool and patio products such as TuffScreen® No-See-Um screening.
If youre in the market to buy metal screen, Phifer® offers Aluminum No-See-Um screen that is perfect for keeping most small insects out, and providing great visibility. As for fiberglass screen, UltraVue 2® is an excellent choice of screen that provides unobstructed views and is infused with Water Shed Technology® to keep screens clear by preventing water collection on the screen while also repelling dirt and debris. TuffScreen® is a very popular polyester mesh product for screen porches or pool enclosures where durability is a priority feature. To buy any of these products now, click here.

A window screen (also known as insect screen, bug screen, fly screen, flywire, wire mesh, or window net) is designed to cover the opening of a window. It is usually a mesh made of metal, fibreglass, plastic wire, or other pieces of plastic and stretched in a frame of wood or metal. It serves to keep leaves, debris, bugs, birds, and other animals from entering a building or a screened structure such as a porch, without blocking fresh air-flow.
Most houses in Australia, the United States and Canada and other parts of the world have screens on windows to prevent entry of flying insects such as mosquitoes, flies and wasps. 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.
For screens installed on aluminium frames, the material is cut slightly larger than the frame, then laid over it, and a flexible vinyl cord, called a spline, is pressed over the screen into a groove (spline channel) in the frame. The excess screen is then trimmed close to the spline with a sharp utility knife. Common spline sizes range from 3.6 mm (0.140 in) to 4.8 mm (0.190 in), in increments of 0.25 mm (0.010 in).
The spline is often manufactured with parallel ridges running along the length of the spline to provide a better grip and compression when it is pressed into the spline channel. A spline roller 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.

"Wove wire for window screens" are referenced in the American Farmer in [1]. Advertisement for wire window screens also appeared in Boyd's Blue Book in . Two wire window screens were exhibited at Quincy Hall in Boston in .
In Gilbert, Bennett and Company was manufacturing wire mesh sieves for food processing. An employee realized that the wire cloth could be painted gray and sold as window screens and the product became an immediate success. On July 7, , Bayley and McCluskey filed a U.S. Patent, number for screened roof-top rail-car windows, allowing ventilation, while preventing "sparks, cinders, dust, etc." from entering the passenger compartment. By , E.T. Barnum Company of Detroit, Michigan advertised screens that were sold by the square foot.[2]
Window screens designed specifically to prevent insect entry were not patented in the United States, although by several patents were awarded for particular innovations related to window screen design. By the s, parasitic diseases were largely eradicated in the United States in part due to the widespread use of window screens.[3] Today many houses in Australia, the United States and Canada have screens on operable windows.[4]

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.

The most common materials used for the mesh of window screens are aluminum and fiberglass. 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.
For applications requiring greater strength, such as screened doors (which have a larger area than windows), nylon and polyester screening is often used. However, these materials are not generally used for smaller applications such as window screens.[6]
Bronze insect screening is much more expensive, but gives much longer service than either aluminum or fiberglass. When first installed, it has a bright gold color; this weathers to an unobtrusive dark charcoal within a year or less. Weathered bronze darkens the external appearance of windows to approximately the same degree as charcoal or black aluminum. Bronze is somewhat more resistant to denting than aluminum. 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.
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.
Do-it-yourself screen and frame replacement kits are widely available at hardware and home improvement stores. One kind is composed of straight aluminum sides (which can be cut to size) and plastic corner inserts. Screen replacement kits usually consist of a roll of nylon screening fabric and a generous supply of rubber spline.
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.[citation needed] Other manufacturers offer screens designed to filter for pollen and dust.
Temporary, removable screens that fit within window tracks of double-hung windows are a common expedient widely available in hardware and home improvement stores. Typically 30 to 76 centimetres (12 to 30 in) high, these screens are wedged beneath the lower sash of a double-hung window and 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.

Typically, metal screen frames (roll form) are 6.4 mm (14 in), 7.9 mm (516 in), 9.5 mm (38 in) or 11 mm (716 in) in thickness by 19 mm (34 in) and 25 mm (1 in). The most common sizes are 7.9 mm (516 in) and 11 mm (716 in) by 19 mm (34 in). The 6.4 mm (14 in) and 7.9 mm (516 in) sizes are generally used for single hung windows, while the two larger sizes are used for double hung windows. As 9.5 mm (38 in) is not a common size, the 7.9 mm (516 in) thickness may be used instead and shimmed as needed. They come in a variety of colors including unpainted, white, bronze, tan, black, desert sand, etc. The screen may also include a crossbar for added strength.
Fiberglass screen material is typically available in 30 m (100 ft) rolls in varying widths, from 46 to 305 cm (18 to 120 in) wide. Aluminum screen material is available in 30 m (100 ft) rolls except the range of available widths is less than for the more commonly used 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.
Fiberglass solar screens provide over 75% of UV protection, by using thicker strands and a closer mesh than regular 18x14 fiberglass window screening. There is some reduction in visibility, but this can be advantageous, since solar screens are difficult to see through from the outside, while easier to see through from the inside.
Finer meshes have been developed to prevent very small insects, often called "noseeums" from flying through. The finer mesh screens are also used to prevent pollens and allergens from entering homes in order to control allergic reactions.
