Screen is available in a variety of materials, but aluminum and fiberglass are by far the most common. Specialty screening includes extra-heavy pet-resistant screen; screen that blocks as much as 90% of solar-heat gain; and noncorroding bronze, monel (an alloy of nickel and copper), or stainless steel for coastal installations. Prices range from about 17¢ per sq. ft. for fiberglass to as much as $5 per sq. ft. for monel.
Standard door and window screen has a mesh size of 18×16, indicating that there are 18 strands per inch in one direction and 16 in the other. This screen can be used on a porch, but a mesh size of 18×14 uses a slightly larger-diameter wire, is stronger, and spans larger openings. If your area is plagued by tiny biting insects (sometimes called “no-see-ums” by their victims), 20×20 mesh may be a better choice.
Fiberglass
Standard fiberglass insect screen is made from vinyl-coated fiberglass threads in charcoal and silver gray. It won’t crease like aluminum screening, but it’s more opaque. It’s also more flexible and, therefore, easier to install in an aluminum frame with a spline or in one of the proprietary screen-framing systems.
Some sun-control and pet screening is made from vinyl-coated polyester, which is stronger and heavier than fiberglass.
Standard fiberglass Sun control Pet screeningStandard fiberglass screen comes in widths up to 84 in. and costs about 17¢ per sq. ft. Pet screening is about 60¢ per sq. ft., and Phifer’s Super Solar screen (205-345-2120; www.phifer.com), in charcoal and silver gray, costs $1.53 per sq. ft.
Metal
Available in bright, charcoal, and black finishes, aluminum screening is the least visible to the eye. Aluminum, however, dents and creases fairly easily, and it can oxidize in coastal areas. It’s available in widths up to 72 in. and costs about 26¢ per sq. ft.
Probably the most common of the high-performance alloy screens, bronze won’t readily oxidize in salty air along the coast. It turns from a bright, coppery color to a dark brown, or even green, with age. It’s available in widths up to 60 in. and costs about $1.10 per sq. ft.
Stainless steel and monel stand up extremely well to salty air, but their durability comes at a cost-anywhere from $2.25 to $5 per sq. ft., depending on weave and quantity.
Save time with screening systems
If you’re looking for something beyond the stretch-and-staple approach of installing screen, there are several alternatives.
Custom panels
Buying premade panels of wood or aluminum, which are installed against stops applied to framed openings, is faster than installing screen yourself, and the panels can be removed and rescreened individually if they become damaged. Storm panels can be substituted for screen to extend the use of a porch into cooler weather. Connecticut Screen Works Inc. (www.connscreen.com; 203-741-0859) is one such supplier. It has made panels as large as 9 ft. by 18 ft., but the company recommends that buyers limit the maximum size to 48 in. wide by 80 in. tall. Prices for a basic panel with aluminum screen start between $50 and $75 per running foot, which includes a screen door and mounting hardware for the panels.
Proprietary track systems
At least two companies manufacture track that is attached to the framing and holds the screen tightly in place. Both types work best with fiberglass screen, although you can use aluminum screen. These systems make screen repair a snap.
ScreenEzeThe screen is tightened as a piece of vinyl trim is snapped over an aluminum extrusion mounted to the framing. No splines are used. To replace a piece of torn screen, pull off the trim, cut a new piece of screen, and reinstall the trim. The track and cap retail for about $2 per ft.
Screen TightA plastic extrusion is attached to the framed openings, and the screen is held in place with a spline and capped with a separate extrusion. If you get the hang of using the spline tool, replacing damaged screen is relatively simple. An 8-ft.-long section of track and cap is about $7.50.
Read the complete article…Strength, durability, cost and outward visibility are some of the considerations to keep in mind when choosing mesh material. The right mesh material will depend on which factors matter more to you.
Fiberglass is one of the most commonly used mesh materials for insect screens. The reason for its popularity is simple – it is inexpensive and offers good outward visibility. Fiberglass is also lightweight, flexible and corrosion-resistant. Some manufacturers may coat the fiberglass with PVC to improve its strength.
The greatest disadvantage of fiberglass is that it’s not as durable as other mesh materials. It is prone to tearing/fraying at the edges and tends to stretch over time. When exposed to strong sunlight for long periods of time, its strength will deteriorate and discolouration may also occur.
Pros
Cons
Polyester mesh has been gaining popularity as an alternative to fiberglass mesh. It is flexible, tear-resistant and less prone to sagging, making it stronger and more durable. It is usually also coated with vinyl, which serves as an additional protective barrier. Polyester mesh coated with a thicker layer of vinyl is often used in pet screens. The thick vinyl coating grants increased resistance to abrasions, which makes it difficult for pets to damage the screen.
A downside of polyester mesh is that the thick coating results in a decrease in outward visibility. It is also more expensive than fiberglass. And if you’re opting for vinyl-coated polyester, you’ll have to fork out much more.
Pros
Cons
Polyethylene (PE) and polypropylene (PP) are mesh materials that have caught on in recent years. Both plastics are used in a wide variety of applications and are similar in physical properties. When used to make screen mesh, they are commonly available as PE mesh, PP mesh or PE + PP mesh (made with a combination of PE and PP).
Both PE and PP are strong fabrics that are tear-resistant and less prone to sagging. PE is a good electrical insulator and is slightly sturdier than PP. Meanwhile, PP has a higher chemical resistance and is more lightweight. Both are mildew-resistant and offer good outward visibility. Like the polyester mesh, most PE/PP mesh sold are coated to further enhance their strength and durability. Coated PE/PP mesh is also UV-resistant and waterproof.
While PE/PP mesh has many strengths, one drawback is that they are not suitable for pet screens. The coating on PE/PP mesh is not as thick, which makes it less resistant against scratches and damage caused by pets. PE/PP mesh is also more expensive than fiberglass mesh.
Pros
Cons
Another material used to make screen mesh is aluminium. While popular in countries such as Australia and the USA, aluminium mesh is rarely seen in Singapore. Aluminium mesh offers superior strength and durability as well as excellent outward visibility. It cannot be torn and its rigidity means you won’t have to worry about the screen sagging. The mesh often comes in a protective finish that is corrosion-resistant.
However, as you may have expected, aluminium mesh is very expensive. It may also dent/crease upon heavy impact.
Pros
Cons
Finally, we have the stainless steel mesh. Stainless steel is the strongest and most durable mesh material available. It is rust- and corrosion-resistant, offers excellent outward visibility and will not stretch or sag. Other than its natural colour, the mesh may also be powder-coated for a black finish which further improves visibility.
The main disadvantage of using stainless steel mesh is the cost. It is easily the most expensive mesh of the lot due to the premium material used. Additionally, the mesh may also dent or kink upon heavy impact.
