Following paragraphs discuss the desired qualities of both types of awnings so that you find it easy to buy awnings, whether residential or commercial. Residential Awnings: There was a time when almost all residential building had awnings. When artificial air conditioning system was not invented, awnings were popular for keeping indoor environment cool. It was the most natural way to make rooms comfortable during summer. With increased energy cost, people have again started to shift towards awnings. Retractable awnings are quite popular nowadays. The qualities people look in a residential awning are as follows: Adequate element protection: Protection from sun, rain and snow is the prime reason for installing awning at home. While purchasing, make sure the materials used in your awning can protect you from heat and rain.
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.
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.
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.
