Installation in a Few Easy Steps The general installation process for both traditional retractable awnings and drop screens is pretty simple: attach the correct number of mounting brackets using the appropriate fixing and insert the torsion (square) bar. The simplicity of installing awnings is what makes them ideal for do-it-yourself weekend projects. The exact installation steps, naturally, vary depending on the awning being installed (so always read the manufacturers specific instructions!), but these are the general processes. For a drop screen:1. Assemble the screen itself, putting together the roller (called the headerbox), similar to an old-fashioned shade.2. Install the mounting brackets at the top and around the door frame or the beam of the gazebo or porch.3. Snap in the headerbox, making sure that the bottom rail of the screen is toward the inside of the room.4. If there are vertical side guides, measure and cut them according to the height of the opening, and then screw them in place and snap them in position with the headerbox. If there are guide wires, screw the bottom brackets into place, and attach the wires to the cassette. Be sure everything is level and plumb.
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.
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:
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.
