Retractable awnings offer a slew of advantages over fixed awnings, from easy installation to longer lifetimes. As the name indicates, retractable awnings retract, folding to help control the placement of the shade or to protect the awning. Because of their durability, retractable awnings can be long-term fixtures on the exterior of a home or commercial building, providing better outdoor living and working spaces; offering, sun, heat, glare and ultraviolet ray (UV) protection; and enhancing exterior appeal. Finding Purpose: Uses for Retractable Awnings Retractable awnings are most commonly used for element protection. Over 70% of awnings are purchased specifically to provide shade. This shade is primarily for comfort, to cut down on the brightness of the sun, cool off outdoor ambient temperatures, and make entrances more welcoming, but there are other benefits as well:
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.
There are dozens of styles of retractable awnings, determined mainly by the frame shape: Lateral arm awning - the most common, and oldest, retractable awning style, consisting simply of two or more arms, the front bar, mounting bar and the fabric. This is the most popular style for homes and commercial buildings; this is also the most scalable style, extending (projecting) as far as 17 feet without external supports. Dome - an awning with curved ribs, which forms a rounded shape when fully extended; these tend to have a significantly shorter extension (projection) than lateral arm awnings, extending only about five feet out maximum from the mount point. An elongated dome can have a longer projection than a standard dome style, almost double. Dome awnings are common for commercial properties and for window and door awnings. Drop screen - a kind of retractable awning which is mounted vertically so it extends downward. This style of awning has the mounting bar and fabric, but no arms since it simply "drops" down. This is mainly used to screen patios, gazebos, and other outdoor areas from glare, heat, rain, UV rays, direct sun, mosquitoes, and pollen.
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.
