What is the Difference Between Aluminum and Fiberglass Window Screens?

Window ScreenWindow screening was once characterized by bug barriers that were woven from horse hair. Modification in the textile looms replaced horse hair with galvanized screening; however, steel had limitations due to rusting. Steel gave way to non rusting alternatives such as aluminum and fiberglass. Today, these are the most common materials in the market. The two make good window screening options, however, it helps to know the difference between aluminum and fiberglass window screens so that you can make the right choice based on the application.

Aluminum Screens

Aluminum screens are made from Al-Mg alloy wire. It is one of the top quality materials for window screens. It is typically available in three colors: dark gray, black and bright aluminum. Among these colors black is the least noticeable. It is important to remember that darker colors offer better outward visibility. This is because they have less glare and light reflectance. Dark gray aluminum can be easily made to complement frame systems and painted windows. Bright aluminum resembles raw aluminum; however, it has a unique clear coating that goes a long way to help maintain the aluminum sheen.


Aluminum screening is typically available in an 18 x16 mesh. It can be used both for window and door applications. It is rust resistance, corrosion resistance and light weight. Durable and strong screening and does not sag. To strengthen the weave, a protective finish is applied. It is supplied in cut pieces and rolls, according to Affordable Window Screens.

Fiber Glass

Overtime, fiberglass has been the standard material for window screens, because it is affordable and flexible. Fiberglass also comes in a wide selection for different applications. Fiberglass is basically sold in heavy-duty, fine and standard grades. Fine fiberglass is ideal in areas where there are small insects such as the coastal and marshy regions. The standard grade is the most common and also the cheapest option available. Heavy duty fiberglass is ideal for large windows which need strong screens. It is also great in windy regions as it can withstand harsh weather. Fiberglass is easily broken and scratched and with time it can become brittle. Fiberglass provides up to 75percent UV protection. Reduction in visibility can be achieved by using a closer mesh (18 x14). During the day, the screen appears almost opaque but it still offers good visibility from the inside. You can get fiber glass in bronze, dark bronze, charcoal, gold and silver gray. The most common colors are silver gray and charcoal.

Difference Between Aluminum and Fiberglass Window Screens

Fiberglass is generally less expensive as compared to aluminum. It also does not dent when pushed or hit. Fiberglass however, is somehow darker than the aluminum mesh, this means that it gives it a darker external appearance and therefore reduces the amount of light getting into the room. Another disadvantage of fiberglass over aluminum is that it tends to degrade with time due to long exposure to UV light. This quality also makes it break and fray easily and hence does not last as long as aluminum. Fiberglass screens are sold in 100 foot rolls of varying widths ranging from 18 to 120 inches. Aluminum screens are also purchased in 100 foot rolls; however, the range available is limited as compared to fiberglass, according to Wire Screen.

As evidenced in the difference between aluminum and fiberglass window screens, both make good options it all depends on personal preferences.
