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.
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.
Where should the awning be placed? If the goal is to lower energy costs, than the awnings should cover windows or doors facing the direction that receives the most sustained sun. If the awning is to extend comfortable living areas outdoors, consider large awnings or series of awnings that track the sun and control glare, heat, and UV rays. What design suits the living space and purpose? Retractable awnings can be custom-sized to fit the target area exactly. Additionally, there are dozens of different retractable awning styles, like small canopies for windows, elongated dome canopy awnings for wide exteriors, or vertical screens and side arm/drop arm retractable awnings for patios. Make sure you find the kind of style that best fits your space. Does the awning need to retract? Under what circumstances? Retractable awnings have a variety of sensors and accessories which control the awning automatically. Sun, rain, motion, and wind sensors can automatically retract the awning to protect them from the elements or to extend them to provide protection at the required time.
Consider whether the additional cost for a high end retractable awning is worth the additional quality. The functional distinctions between high and low quality retractable awnings are significant: - Commercial (high quality) awnings have non-prorated frame warranties of 25 years and fabric lifetimes as long as 12-15 years, while residential (budget) lines have frame warranties and fabric lifetimes of five years or less. - Commercial grade retractable awnings come in custom sizes, down to an inch measurement, while many residential lines have only a few standard sizes. - Commercial retractable awnings have hundreds of fabrics available, while budget lines usually have much fewer color and pattern options. Additionally, high quality awnings use a woven fabric called solution-dyed acrylic which resists fading, mildew, and rot, while budget awnings use cheap materials such as canvas (which fades quickly) or vinyl (which absorbs the heat and does not breathe).
