Retractable awnings were quick to catch on in Europe, from open air markets to apartments and homes. In fact, the classic lateral arm awning is called a California Style Awning in Europe - and a European Style Awning in the US. Now, the retractable awning market is decidedly driven by Europe. Millions of retractable awnings are sold there annually and are found on the majority of homes and businesses, even being considered in the architectural design process. The highest quality manufacturers, most innovative new designs, and emerging trends are coming from European companies. By comparison, the awning market in America has been limited to mainly commercial buildings. Substantially fewer awnings are sold in the United States yearly - less than 50,000 - so the market, according to the Industrial Fabric Association International, is only about 2% saturated. Theres room for a change.
How much shade coverage is required. What the width of the awning should be, based on the shade area. Add at least 12 inches to maximize coverage for sun and rain protection. How far out the awning extends (the projection), based on the shade area. There is a natural slope to an awning, so the actual shade is several inches shorter than the full projection. How high to mount the awning. Because of the awnings slope, the front of the awning is lower than the mounting position; this difference is the drop. The recommended drop is 3 inches per foot of projection. So, if the awning has a 12-foot projection, the drop is about 36 inches. To get a 7-foot clearance under the front bar, the awning has to be mounted at least 10 feet high. Scout out a mounting place that is free of obstructions (no lights, gutters, wiring, or ornamentation) and has adequate clearance around any doors or windows. For screens, make sure that any doors swing away from the screen. For retractable awnings, make sure the awning can extend its full projection without running into a tree, patio, roofline, or fence.
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.
