Specifically for retractable awnings, most Asian-produced lines are imitative rather than original, meaning they use standard designs done on the cheap without any engineering design or engineering drawings. In addition, almost all Asian vendors lacks TÜV or Eurolab certifications. Thats not to say that every budget line is bad. Obviously, price is a factor (though it becomes less of a factor when the usable life of a budget awning is about a quarter of a commercial/high-end awning). Also, a few companies focusing on residential lines put the effort in meeting with Asian manufacturers at trade shows, even touring their facilities. Even with budget lines, the quality of the company is reflected in their service agreements, return policies, and customer service.
Why is the awning being used? Figure out clearly why that area needs protection and what element you want to control. The requirements for the awning are different for rain protection and sun protection. For example, to use the awning in wet areas, have at least a 3 inch slope, or pitch, to the awning per foot of extension. If an awning extends 12 feet, the pitch should be 36 inches, meaning that the awning must be mounted 3 feet higher than the height at the end of the awning fully extended. Awnings in sunny locations with little can be nearly flat. For other situations, awnings may not be ideal; high, sustained winds can seriously damage awnings, as can the weight from snow, ice, and hail. Accessories like wind or motion sensors can also be used to protect the retractable awning in less than ideal conditions.
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.
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.
