There are also dozens of different accessories for retractable awnings which make them easier to operate. A couple of common ones: Anemometer - a device which monitors wind speed; this is used with wind sensors. Sensors - devices which monitor different atmospheric conditions and trigger the motor to retract or extend the awning accordingly; there are four major kinds of sensors, including sun (light) sensors, wind sensors, rain sensors, and motion sensors (which monitor movements, such as wind gusts) Motor - a device which automatically moves the awning; motors are enclosed in the roller tube.Terms: Materials The retractable awning materials are the true indicator of quality - because the kind of materials used translates into quality, not the expense of the materials. For the fabric, there are two major categories of fabrics:
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.
Other retractable awning features impact how well the awning wears, and, therefore, how easy it is to maintain: Electro-statically powder-coated aluminum frames to resist corrosion and chipping Sealed and self-lubricating retractable awning motors Weather-sealed wind, motion, rain, and sun sensors and other accessories Stainless-steel mounting hardware to prevent staining or bleeding from rust Kevlar® brand straps in the arms, not steel cables which will rust TÜV product approved and Eurolab certified frames These components make the average lifetime of a retractable awning 12-15 years for fabric and 25 years for the frame - almost five times longer than most fixed awnings or canopies, and without the need to professional cleaning or seasonal storage problems. With retractable awnings, the keyword for maintenance is effortless.
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.
