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.
Consider whether the additional cost for a high end retractable awning is worth the additional quality. The functional distinctions between high and low quality retractable awnings are significant: - Commercial (high quality) awnings have non-prorated frame warranties of 25 years and fabric lifetimes as long as 12-15 years, while residential (budget) lines have frame warranties and fabric lifetimes of five years or less. - Commercial grade retractable awnings come in custom sizes, down to an inch measurement, while many residential lines have only a few standard sizes. - Commercial retractable awnings have hundreds of fabrics available, while budget lines usually have much fewer color and pattern options. Additionally, high quality awnings use a woven fabric called solution-dyed acrylic which resists fading, mildew, and rot, while budget awnings use cheap materials such as canvas (which fades quickly) or vinyl (which absorbs the heat and does not breathe).
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.
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.
