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.
Following paragraphs discuss the desired qualities of both types of awnings so that you find it easy to buy awnings, whether residential or commercial. Residential Awnings: There was a time when almost all residential building had awnings. When artificial air conditioning system was not invented, awnings were popular for keeping indoor environment cool. It was the most natural way to make rooms comfortable during summer. With increased energy cost, people have again started to shift towards awnings. Retractable awnings are quite popular nowadays. The qualities people look in a residential awning are as follows: Adequate element protection: Protection from sun, rain and snow is the prime reason for installing awning at home. While purchasing, make sure the materials used in your awning can protect you from heat and rain.
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:
How easy an awning is to maintain depends a lot on how it is made, and there are differences between retractable awnings. The fabric on low-quality awnings, particularly cheaper fabrics like canvas and vinyl, is the component most vulnerable to damage: rotting or mildew from rain and humidity, sun exposure, frayed seams, cracking, and fading. Quality retractable awning companies use solution-dyed acrylic, a chemical fiber with the color embedded into it. Solution-dyed acrylic is a woven fabric, so it dries quickly, avoiding mold or mildew. Since is a synthetic fiber, it doesnt rot. And, since the color is part of the fiber itself, it lasts as long as 15 years before being replaced.
