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.
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.
There are also dozens of different accessories for retractable awnings which make them easier to operate. A couple of common ones: Anemometer - a device which monitors wind speed; this is used with wind sensors. Sensors - devices which monitor different atmospheric conditions and trigger the motor to retract or extend the awning accordingly; there are four major kinds of sensors, including sun (light) sensors, wind sensors, rain sensors, and motion sensors (which monitor movements, such as wind gusts) Motor - a device which automatically moves the awning; motors are enclosed in the roller tube.Terms: Materials The retractable awning materials are the true indicator of quality - because the kind of materials used translates into quality, not the expense of the materials. For the fabric, there are two major categories of fabrics:
Longevity. Fixed awnings have a fabric lifetime of five years or less because of constant exposure to the sun, snow, rain, and wind, all of which can fade or tear the fabric. Retractable awnings have a huge advantage in being able to retract - the fabric can be protected in adverse weather conditions. Combined with options like a motor and sensors (for light, wind, rain, and motion), the awning can be closed automatically in conditions which would normally damage the fabric or frame. Retracting the awning when its not in use, like on shady or cold days, cuts down on sun damage to the fabric from UV exposure. With a retractable awning, the average lifetime for the fabric is 15 years - three times better than a fixed awning. Since retractable awning frames have warranties of up to 25 years and motors have warranties up to 5 years, motorized retractable awnings offer a really excellent cost investment.
