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.
Installation in a Few Easy Steps The general installation process for both traditional retractable awnings and drop screens is pretty simple: attach the correct number of mounting brackets using the appropriate fixing and insert the torsion (square) bar. The simplicity of installing awnings is what makes them ideal for do-it-yourself weekend projects. The exact installation steps, naturally, vary depending on the awning being installed (so always read the manufacturers specific instructions!), but these are the general processes. For a drop screen:1. Assemble the screen itself, putting together the roller (called the headerbox), similar to an old-fashioned shade.2. Install the mounting brackets at the top and around the door frame or the beam of the gazebo or porch.3. Snap in the headerbox, making sure that the bottom rail of the screen is toward the inside of the room.4. If there are vertical side guides, measure and cut them according to the height of the opening, and then screw them in place and snap them in position with the headerbox. If there are guide wires, screw the bottom brackets into place, and attach the wires to the cassette. Be sure everything is level and plumb.
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.
European lines have the highest quality, partly because awnings have been used in Europe for thousands of years and are tightly integrated with building design concepts. This long history has led to the best designed and manufactured awnings available: Tight manufacturing standards- Internationalized, rigorous QA testing standards- Certification processes for materials- Durable material quality for frames, fabrics, and threads- Continuously evolving styles, features, and development On the other hand, most budget (residential) retractable awnings tend to be made in China, an area plagued by consistent complaints about poor quality control, poor materials, and poor labor. With budget lines, product quality, sometimes even product materials, varies significantly between lots. - Lower quality materials- Lack of testing or certifications- Limited styles- Inconsistent manufacturing quality.
