UV rays, high wind, gusts, and rain - basically, normal weather - cause the most damage to awnings. Fading, molding, and tearing fabric. Twisting fixed frames from high wind damage or the weight of snow or pooling rain. In only two or three years, fixed awnings and canopies already show substantial wear, which is why the lifetime of most fixed awnings and canopies is only five or six years before the awning need to be replaced. Retractable awnings are closed when not in use, which cuts weather damage. That makes the maintenance much easier on retractable awnings compared to permanent awnings and canopies - there is no need to hunt down replacement parts, replace fabric every couple of years, or attempt to wrangle awnings down and into storage for winter.
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.
How much shade coverage is required. What the width of the awning should be, based on the shade area. Add at least 12 inches to maximize coverage for sun and rain protection. How far out the awning extends (the projection), based on the shade area. There is a natural slope to an awning, so the actual shade is several inches shorter than the full projection. How high to mount the awning. Because of the awnings slope, the front of the awning is lower than the mounting position; this difference is the drop. The recommended drop is 3 inches per foot of projection. So, if the awning has a 12-foot projection, the drop is about 36 inches. To get a 7-foot clearance under the front bar, the awning has to be mounted at least 10 feet high. Scout out a mounting place that is free of obstructions (no lights, gutters, wiring, or ornamentation) and has adequate clearance around any doors or windows. For screens, make sure that any doors swing away from the screen. For retractable awnings, make sure the awning can extend its full projection without running into a tree, patio, roofline, or fence.
The Different Levels of Retractable Awnings etractable awning companies usually draw distinctions between the different levels of quality which they sell. The highest quality level is for commercial grade retractable awnings. Commercial lines have high-grade manufacturing and use extremely durable, heavy duty materials to increase their lifetimes. The other common designation is residential awning, which are usually less expensive to produce. The less expensive, lower grade materials mean many residential awnings have shorter life spans. One important thing to recognize: The difference between commercial and residential awnings is not because of different styles, sizes, or options. Theres nothing special about a commercial awning that makes it too grand for homes. The difference that sets apart commercial awnings is their superior quality of workmanship and materials.
