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.
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.
Following paragraphs discuss the desired qualities of both types of awnings so that you find it easy to buy awnings, whether residential or commercial. Residential Awnings: There was a time when almost all residential building had awnings. When artificial air conditioning system was not invented, awnings were popular for keeping indoor environment cool. It was the most natural way to make rooms comfortable during summer. With increased energy cost, people have again started to shift towards awnings. Retractable awnings are quite popular nowadays. The qualities people look in a residential awning are as follows: Adequate element protection: Protection from sun, rain and snow is the prime reason for installing awning at home. While purchasing, make sure the materials used in your awning can protect you from heat and rain.
Different Reasons for Using Awnings Various factors have come into play for why Europe has, for nearly a century, been consistently integrating retractable awnings into architectural plans. Many of the initial reasons were cultural; prevalent open air markets had contributed to a long history of fixed awning use, so it was a natural transition to easier to use and longer-lasting retractable awnings. More practically, though, the widespread use of retractable awnings comes down to cooling and energy efficiency. Europe has very high energy costs and, because of many old homes and flats, most residences do not have air-conditioning systems installed. Therefore, European homeowners have had an imperative to find inexpensive, effective cooling and efficiency products - and one of the most effective methods for controlling interior heat is retractable awnings.
