Following paragraphs discuss the desired qualities of both types of awnings so that you find it easy to buy awnings, whether residential or commercial. Residential Awnings: There was a time when almost all residential building had awnings. When artificial air conditioning system was not invented, awnings were popular for keeping indoor environment cool. It was the most natural way to make rooms comfortable during summer. With increased energy cost, people have again started to shift towards awnings. Retractable awnings are quite popular nowadays. The qualities people look in a residential awning are as follows: Adequate element protection: Protection from sun, rain and snow is the prime reason for installing awning at home. While purchasing, make sure the materials used in your awning can protect you from heat and rain.
Differences in Style The different reasons for retractable awning use in Europe and the US have produced different emphases on style. Because awnings had a stylistic influence in European history which transitioned to efficiency uses, European awning fabrics and designs tend to be more dramatic and flamboyant. For example, European fabric lines average about 400 fabric designs, while American lines average 200. Color choices in Europe tend to be lighter and brighter. American homeowners, approaching retractable awnings as a functional addition to a house, without the stylistic background, tend to be conservative, choosing fabrics in blacks and grays in sedate stripes and staying with more traditional frame styles.
Awnings have been common for more than 2000 years; retractable awnings have been around for almost 150 years. While the history of using awnings stretches far back in Europe and retractable awnings are commonly used there today, theyre rare in the United States - despite the fact that retractable awnings were invented in the US. This uneven adoption has led to an exposure of design options in Europe - intricate frames, new types of retractable frames, bold colors, and luscious patterns - while America, treating awnings as a practical afterthought, has stayed more conservative. A Quick History Some form of awnings has been around for millennia, starting in Egypt and the Middle East and spreading across the Roman Empire. Most of those were fixed canopies of mats, skins, or fabric bolts hung over poles. In the mid-1800s, shop owners began using movable awnings, which simply bunched up the fabric when it was taken down. In the latter part of the century, they began rolling awnings on a tube, cleanly retracting them and keeping the fabric safe. With minor variation, this is the same basic design used today on lateral arm retractable awnings.
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.
