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.
Although any retractable awning style is used on homes, most budget lines are limited to a single design. High quality awning lines can offer a half dozen styles or more.- High quality lines offer support for years for parts, even for additional options. Budget lines, particularly at big-box chains, only offer add-ons for a single season and service can lapse within a year, if its even available. When buying budget, the quality of the company becomes much more important. There are some dependable budget retractable awning manufacturers and retailers out there, with solid support, good products, and attractive awning styles. You just have to look.
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.
Seasonal Storage Means Keep It Closed Most awning frame damage comes from some kind of stress, either high winds or gusts which twist the frame or weight from heavy rain, snow, even lots and lots of leaves, which can distend the fabric and bend the frame. It is not necessary to take down a retractable awning to protect it in winter. Just close it. Many retractable awnings have an optional hood, a shield which covers the awning when it is retracted and offers additional protection for the fabric. In winter, it can also be helpful to remove the valance, the strip of fabric which hangs at the front of the awning. What Makes the Difference Retractable awnings are much easier to maintain than fixed awnings or canopies for two major reasons: the fact that the awning retracts and the materials that make it.
