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.
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.
Types of Awnings There are several types of awnings you can use on your home. There are different styles for all uses around your home. You will find the higher end Sunbrella Fabric Awnings, may cost a bit more to purchase, but in the long run they last so much longer they will actually cost you less per year. Lets take a look at the different types and styles of awnings. Retractable Patio Awnings used to be seen only on upscale homes. Now they are more affordable and can last for years without needing any maintenance. These Retractable Awnings can be easily retracted or extended with a hand crank or motor. Motors are available with remotes and wind sensors that will retract the awning automatically in case a sudden storm comes and the awning was left extended. They are also great for outdoor entertaining and will keep any large slider or French doors shaded so your home stays cooler.
Saving Your Environment - Where Awnings Can Go The protection from retractable awnings can apply in unexpected places. The most obvious places where shade would be appealing are in Sun Belt states with sunny and dry climates. Interestingly, retractable deck and patio awnings for sun protection are extremely popular in Pennsylvania, New York, and New Jersey, despite long winters and heavy precipitation, because the high cost of electricity makes energy savings important. Whether a retractable awning is useful depends on how that area will be used and if it is possible to find a design suited to that specific need. Ask yourself a few questions to help identify if a retractable awning can meet your needs.
