Retractable Awnings
Retractable awnings are the "Cadillac" of awnings, ideal for covering a patio or deck. Retractable or lateral arm awnings use spring-loaded arms to provide tension to the fabric as it rolls from the drive tube. The retractable awning is unique in that it may be extended as needed and only as far as needed, offering great flexibility. You can adjust the tilt of the awning up to 45 degrees from the straight-out position. However, retractable awnings are not made to be used in high winds, heavy rains or snow.
Electric motors which are optional are recommended with outdoor plug-ins. Indoor switches can be ordered but require a licensed electrician to install. Motors should include a manual overide so that if the motor stops for some reason the awning can be operated using the hand crank. Electric motors can also be on a remote control, and they can include wind and sun sensors to open and close automatically.
If a retractable awning is exposed to sunlight and weather, a protective hood would be a worthwhile purchase, but if it's positioned under an eve or soffit, a hood is likely not necessary.
