Types of Awnings There are several types of awnings you can use on your home. There are different styles for all uses around your home. You will find the higher end Sunbrella Fabric Awnings, may cost a bit more to purchase, but in the long run they last so much longer they will actually cost you less per year. Lets take a look at the different types and styles of awnings. Retractable Patio Awnings used to be seen only on upscale homes. Now they are more affordable and can last for years without needing any maintenance. These Retractable Awnings can be easily retracted or extended with a hand crank or motor. Motors are available with remotes and wind sensors that will retract the awning automatically in case a sudden storm comes and the awning was left extended. They are also great for outdoor entertaining and will keep any large slider or French doors shaded so your home stays cooler.
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.
There are also dozens of different accessories for retractable awnings which make them easier to operate. A couple of common ones: Anemometer - a device which monitors wind speed; this is used with wind sensors. Sensors - devices which monitor different atmospheric conditions and trigger the motor to retract or extend the awning accordingly; there are four major kinds of sensors, including sun (light) sensors, wind sensors, rain sensors, and motion sensors (which monitor movements, such as wind gusts) Motor - a device which automatically moves the awning; motors are enclosed in the roller tube.Terms: Materials The retractable awning materials are the true indicator of quality - because the kind of materials used translates into quality, not the expense of the materials. For the fabric, there are two major categories of fabrics:
