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.
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.
Usually, then, when a company advertises a "residential awning," theyre signaling that this is a budget line, while "commercial grade awnings" represent high-end lines. Manufacturing Regions and Differences in Quality here are three important manufacturing regions for retractable awnings: Europe, North America, and Asia (mainly China). Each of these manufacturing regions corresponds almost directly to the awning quality: The highest quality retractable awnings are manufactured in Europe, midrange awnings in America, and budget lower quality awnings in China. Most awning companies in the USA sell either commercial awnings from Europe or budget lines from China.
Part of the appeal of retractable awnings, and one feature which makes them a practical asset for both home and business owners, is how easy it is to keep them looking beautiful and functioning smoothly. For a retractable awning, "maintenance" boils down to occasional washing and routinely closing it to keep the awning fabric and frame in prime condition. Gentle Cleaning The major concern for retractable awning fabric is stains caused by leaves, vines, tree sap, and other elements like smoke, particularly in autumn as leaves fall and plants begin to die back. Cleaning an awning has only two steps: 1. Use a broom to gently remove leaves and debris. 2. Hose down the awning, making sure to avoid the end of the awning with the motor, if motorized.
