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.
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.
Window Awnings are available in traditional and contemporary styles. Traditional style window awnings have sides that will give you more sun protections than awnings without sides. Awnings with sides are especially needed for East and West facing windows. Spear Window Awnings are made with wrought iron frames with spear finials. Spear Awnings look great on adobe and more modern homes. Drop arm Awnings for windows roll up on a roller tube and can be motorized. Drop Arm Awnings with motors are convenient for second story windows so they can be retracted easily from indoors. Porch Awnings around the perimeter of your porch adds privacy and protection. Porch Awnings can keep your porch cool will protecting it from rain and the sun. You can use Window Awnings around a porch or Canvas Porch Roller Curtains which will can roll up and down with a simple rope and pulley system. Porch Valances are also a popular decorative addition to porches. These Canvas Valances are for decorative purposes but do not have much sun protection because they are a small accent to a porch. They are 12" - 14" tall and wrap around a porch to add color and will soften the hard lines of a porch. They are especially popular on coastal homes on the East coast.
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.
