Awnings have been common for more than 2000 years; retractable awnings have been around for almost 150 years. While the history of using awnings stretches far back in Europe and retractable awnings are commonly used there today, theyre rare in the United States - despite the fact that retractable awnings were invented in the US. This uneven adoption has led to an exposure of design options in Europe - intricate frames, new types of retractable frames, bold colors, and luscious patterns - while America, treating awnings as a practical afterthought, has stayed more conservative. A Quick History Some form of awnings has been around for millennia, starting in Egypt and the Middle East and spreading across the Roman Empire. Most of those were fixed canopies of mats, skins, or fabric bolts hung over poles. In the mid-1800s, shop owners began using movable awnings, which simply bunched up the fabric when it was taken down. In the latter part of the century, they began rolling awnings on a tube, cleanly retracting them and keeping the fabric safe. With minor variation, this is the same basic design used today on lateral arm retractable awnings.
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 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:
Retractable awnings were quick to catch on in Europe, from open air markets to apartments and homes. In fact, the classic lateral arm awning is called a California Style Awning in Europe - and a European Style Awning in the US. Now, the retractable awning market is decidedly driven by Europe. Millions of retractable awnings are sold there annually and are found on the majority of homes and businesses, even being considered in the architectural design process. The highest quality manufacturers, most innovative new designs, and emerging trends are coming from European companies. By comparison, the awning market in America has been limited to mainly commercial buildings. Substantially fewer awnings are sold in the United States yearly - less than 50,000 - so the market, according to the Industrial Fabric Association International, is only about 2% saturated. Theres room for a change.
