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.
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.
The urge to create something new and eye-catching on the blank slate of a home is powerful. As is the urge to save some money and maximize ones efforts. Whether its a change to landscaping, a roof garden, or a casual seating area for customers, retractable awnings or drop screens are an ideal project for do-it-yourselfers because they make a very dramatic difference with relatively little effort. The Planning Stage A major part of installing a retractable awning is finding the perfect place to install it. Retractable awnings are much easier to install than fixed awnings or canopies because they are only mounted on a wall - no need to dig post holes or put in a foundation or grounding - so they can be installed over existing pavements, patios, decks, hot tubs, and gazebos, as well as doors and windows. Retractable awnings are suited to any location where sun, glare, UV rays, or light rain protection is required.
In addition to the practical reasons, Europe has had a long aesthetic tradition with awnings, so retractable awnings are a natural part of any home design, and that organically led into creative and adventurous designs, which made using awnings even more appealing. The US, on the other hand, has had historically cheap and accessible energy, with widespread air conditioning and central air systems. Combined with suburb-motivated home designs, neither energy nor aesthetics has given a compelling reason to include retractable awnings on homes as a standard practice. Energy shortages and price increases in the 1970s, though, did begin bringing retractable awnings to the popular mind as a functional solution for energy efficiency.
