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.
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.
Longevity. Fixed awnings have a fabric lifetime of five years or less because of constant exposure to the sun, snow, rain, and wind, all of which can fade or tear the fabric. Retractable awnings have a huge advantage in being able to retract - the fabric can be protected in adverse weather conditions. Combined with options like a motor and sensors (for light, wind, rain, and motion), the awning can be closed automatically in conditions which would normally damage the fabric or frame. Retracting the awning when its not in use, like on shady or cold days, cuts down on sun damage to the fabric from UV exposure. With a retractable awning, the average lifetime for the fabric is 15 years - three times better than a fixed awning. Since retractable awning frames have warranties of up to 25 years and motors have warranties up to 5 years, motorized retractable awnings offer a really excellent cost investment.
