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:
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).
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.
Why is the awning being used? Figure out clearly why that area needs protection and what element you want to control. The requirements for the awning are different for rain protection and sun protection. For example, to use the awning in wet areas, have at least a 3 inch slope, or pitch, to the awning per foot of extension. If an awning extends 12 feet, the pitch should be 36 inches, meaning that the awning must be mounted 3 feet higher than the height at the end of the awning fully extended. Awnings in sunny locations with little can be nearly flat. For other situations, awnings may not be ideal; high, sustained winds can seriously damage awnings, as can the weight from snow, ice, and hail. Accessories like wind or motion sensors can also be used to protect the retractable awning in less than ideal conditions.
