How easy an awning is to maintain depends a lot on how it is made, and there are differences between retractable awnings. The fabric on low-quality awnings, particularly cheaper fabrics like canvas and vinyl, is the component most vulnerable to damage: rotting or mildew from rain and humidity, sun exposure, frayed seams, cracking, and fading. Quality retractable awning companies use solution-dyed acrylic, a chemical fiber with the color embedded into it. Solution-dyed acrylic is a woven fabric, so it dries quickly, avoiding mold or mildew. Since is a synthetic fiber, it doesnt rot. And, since the color is part of the fiber itself, it lasts as long as 15 years before being replaced.
retractable and fixed awnings: Visibility. Many fixed awnings use stanchions or posts which can block the view; retractable awnings are suspended, either by springloaded arms or with guidewires, depending on the syste. Since they dont require external support, they allow uninterrupted views. Easy installation. Retractable awnings are very simply mounted onto the structure at points like a wall or beam without heavy labor or construction. Variety of use. Retractable awnings can go in small or special areas, such as over windows, where fixed canopies would not be appropriate. Changeability. Retractable awnings can move according to different weather conditions, such as changing the slope of the awning during rain, closing during storms, or using a series of awnings across a long outdoor area that follows the sunlight.
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.
Why is the awning being used? Figure out clearly why that area needs protection and what element you want to control. The requirements for the awning are different for rain protection and sun protection. For example, to use the awning in wet areas, have at least a 3 inch slope, or pitch, to the awning per foot of extension. If an awning extends 12 feet, the pitch should be 36 inches, meaning that the awning must be mounted 3 feet higher than the height at the end of the awning fully extended. Awnings in sunny locations with little can be nearly flat. For other situations, awnings may not be ideal; high, sustained winds can seriously damage awnings, as can the weight from snow, ice, and hail. Accessories like wind or motion sensors can also be used to protect the retractable awning in less than ideal conditions.
