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.
Energy savings. Retractable awnings and vertical drop screens can lower indoor temperatures by 75% and cut air conditioning use by 25%, which significantly lowers energy bills. Element protection. Awnings and drop screens protect areas from weather like rain and wind or from glare and UV rays from the sun. Allergen protection, particularly by vertically-hanging awnings used as screens around patios. Privacy for activity areas such as spas or hot tubs and pools. Retractable awnings can be used for any kind of outdoor exposure, like patios and seating areas, and for indoor areas, such as over windows and doors. There are significant differences between.
Differences in Style The different reasons for retractable awning use in Europe and the US have produced different emphases on style. Because awnings had a stylistic influence in European history which transitioned to efficiency uses, European awning fabrics and designs tend to be more dramatic and flamboyant. For example, European fabric lines average about 400 fabric designs, while American lines average 200. Color choices in Europe tend to be lighter and brighter. American homeowners, approaching retractable awnings as a functional addition to a house, without the stylistic background, tend to be conservative, choosing fabrics in blacks and grays in sedate stripes and staying with more traditional frame styles.
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.
