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.
PVC - a hard polymer also used to make plumbing pipes; this tends to be brittle. Kevlar® - the polymer used to make bulletproof vests; Kevlar® straps in the arms instead of cables are extremely strong and durable and cant rust. Cables - braided metal strands which are used in the arms; these are usually steel, which rusts, leading the cables to discolor the fabric and eventually break. Cables cannot be replaced because they are internal to the arm and inaccessible. Terms: Installation Understanding a few terms about the positioning and installation of the awning can help determine the appropriate size and installation location for your awning: o Mount - what way or location the awning is affixed to the home or building, such as a wall mount, eave mount, soffit, or roof mount. Pitch - the angle that the awning comes down from the mount point to the front bar. Some lateral arm retractable awnings have an adjustable pitch. Projection - how far out from the wall the awning can extend. Load - the stress put on the awning, from wind, snow, even the weight of the awning itself (dead load). Good quality retractable awnings can sustain wind speeds up to approximately 35mph Pooling - water buildup on the canopy which can cause the fabric to sag and stretch.
Usually, then, when a company advertises a "residential awning," theyre signaling that this is a budget line, while "commercial grade awnings" represent high-end lines. Manufacturing Regions and Differences in Quality here are three important manufacturing regions for retractable awnings: Europe, North America, and Asia (mainly China). Each of these manufacturing regions corresponds almost directly to the awning quality: The highest quality retractable awnings are manufactured in Europe, midrange awnings in America, and budget lower quality awnings in China. Most awning companies in the USA sell either commercial awnings from Europe or budget lines from China.
