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.
Why is the awning being used? Figure out clearly why that area needs protection and what element you want to control. The requirements for the awning are different for rain protection and sun protection. For example, to use the awning in wet areas, have at least a 3 inch slope, or pitch, to the awning per foot of extension. If an awning extends 12 feet, the pitch should be 36 inches, meaning that the awning must be mounted 3 feet higher than the height at the end of the awning fully extended. Awnings in sunny locations with little can be nearly flat. For other situations, awnings may not be ideal; high, sustained winds can seriously damage awnings, as can the weight from snow, ice, and hail. Accessories like wind or motion sensors can also be used to protect the retractable awning in less than ideal conditions.
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.
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.
