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.
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.
Other retractable awning features impact how well the awning wears, and, therefore, how easy it is to maintain: Electro-statically powder-coated aluminum frames to resist corrosion and chipping Sealed and self-lubricating retractable awning motors Weather-sealed wind, motion, rain, and sun sensors and other accessories Stainless-steel mounting hardware to prevent staining or bleeding from rust Kevlar® brand straps in the arms, not steel cables which will rust TÜV product approved and Eurolab certified frames These components make the average lifetime of a retractable awning 12-15 years for fabric and 25 years for the frame - almost five times longer than most fixed awnings or canopies, and without the need to professional cleaning or seasonal storage problems. With retractable awnings, the keyword for maintenance is effortless.
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.
