Arms - the part of the frame which folds closed at the elbow when the awning is retracted (rolls in) and opens when the awning is extended (rolls out). Shoulder - the joints on the retractable awning arms where arms attach to the mounting bar. Front bar - the extrusion at the very front of the awning frame. Hood - a cover which fits over the retractable awning frame and fabric; when the awning is fully retracted, the hood protects the exposed fabric, frame, and motor from the elements. Valance - a strip of fabric, usually a few inches high, which hangs from the front bar of the retractable awning. Rib - the cross bars of the frame which support the awning fabric. Not every awning style has ribs, since ribs are often used to create a shape to the awning frame; for example, lateral arm retractable awnings dont have any ribs. Canopy - an elongated, dome, or waterfall style retractable awning.
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.
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.
For a more thorough cleaning, use a soft-bristled brush and dish soap, working from the bottom up. If there is a persistent stain, mix a quarter cup of soap and a half cup of bleach in one gallon of lukewarm water, and soak the stain for 20 minutes, then rinse.There are some things to avoid when cleaning a retractable awning: Do not use a pressure cleaner, as it will damage the fabric. To prevent mold, mildew, or water stains, make sure that the awning is completely dry before closing it, unless there are high winds. Never use detergent on retractable awning fabric and avoid using the bleach-soap cleaner when possible. Most high quality retractable awning fabrics have several fabric treatments to prevent mildew and stains; harsh cleaners remove that treatment. Avoid heat. Some solution-dyed acrylic fabrics are heat-sensitive and can shrink in steam-cleaning, dryers, and hot water.
