How much shade coverage is required. What the width of the awning should be, based on the shade area. Add at least 12 inches to maximize coverage for sun and rain protection. How far out the awning extends (the projection), based on the shade area. There is a natural slope to an awning, so the actual shade is several inches shorter than the full projection. How high to mount the awning. Because of the awnings slope, the front of the awning is lower than the mounting position; this difference is the drop. The recommended drop is 3 inches per foot of projection. So, if the awning has a 12-foot projection, the drop is about 36 inches. To get a 7-foot clearance under the front bar, the awning has to be mounted at least 10 feet high. Scout out a mounting place that is free of obstructions (no lights, gutters, wiring, or ornamentation) and has adequate clearance around any doors or windows. For screens, make sure that any doors swing away from the screen. For retractable awnings, make sure the awning can extend its full projection without running into a tree, patio, roofline, or fence.
o Canvas - a natural fiber (cotton) woven fabric; canvas awnings are prone to fade, mildew, and rot.o Solution-dyed acrylic - a man-made fiber which is woven into a lightweight, breathable fabric; because it is a chemical polymer, the fabric cannot rot. Solution-dyed means that the pigments are included in the fiber solution, which makes the fabric highly fade resistant. For the frame, the important materials are the body and joints: o Electrostatically powder-coated aluminum - a metal frame which is lightweight, durable, and rust-resistant; powder-coating is a method of applying pigment to aluminum frames which is extremely difficult to flake off or damage, unlike enamel or paint.
There are dozens of styles of retractable awnings, determined mainly by the frame shape: Lateral arm awning - the most common, and oldest, retractable awning style, consisting simply of two or more arms, the front bar, mounting bar and the fabric. This is the most popular style for homes and commercial buildings; this is also the most scalable style, extending (projecting) as far as 17 feet without external supports. Dome - an awning with curved ribs, which forms a rounded shape when fully extended; these tend to have a significantly shorter extension (projection) than lateral arm awnings, extending only about five feet out maximum from the mount point. An elongated dome can have a longer projection than a standard dome style, almost double. Dome awnings are common for commercial properties and for window and door awnings. Drop screen - a kind of retractable awning which is mounted vertically so it extends downward. This style of awning has the mounting bar and fabric, but no arms since it simply "drops" down. This is mainly used to screen patios, gazebos, and other outdoor areas from glare, heat, rain, UV rays, direct sun, mosquitoes, and pollen.
Also, retractable awnings have financial benefits over fixed awnings that make them a tempting solution: Retractable awnings are overall less expensive than fixed awnings to install, and they dont require a contractor. Retractable awnings are about a quarter to a third of the cost of permanent construction to cover and utilize the same square footage. Because many styles of retractable awning arms are spring-loaded, there are no support posts to install, to block the view from under the awning, or to act as a potential hazard for children and pets. They require virtually no maintenance, not even mandatory cleaning.Capital Improvement Advantage Retractable awnings have interesting ways of saving a business money: o Direct energy cost savings. Sun protection systems cut heat buildup in a room as much as 77%, translating into a direct utility bill savings of up to 25%. "Dual use" as signage and promotion. Business names, logos, and telephone numbers can be printed on the awning, which saves money on constructing and designing separate signs.
