This style of framed screen is typically done by professional installers, because of the specialized frames and tools required. A recent advancement is frame-less shade screens, which allows a "DIY-er" to install their own exterior shades. Solar shade screens can also be installed at the end of awnings to provide horizontal shade during early morning or late afternoon sun positions.
Retractable patio cover systems are the latest "entry" in to the retractable market. Most of these systems are water-proof as compared to water-resistant (lateral arm awnings) and therefore allow no water penetration through the fabric "roof" section. These systems meet Beaufort scale wind loads up to Beaufort 10 (55 - 63 mph) depending on model and size. Another advantage of retractable patio cover systems is that they can be enclosed on the front and sides using solar shade screens. This allows for an "outdoor room" that can be heated in the winter and air conditioned in the summer.
Commonly used to shade a window, with a roller tube at the top, spring-loaded side arms, and a motor, crank or tape-pull operator. Awnings with sides are commonly known as traditional style awnings as they have been used for many years dating back to the early 19th century using cotton canvas fabric. Canvas was replaced in the 1960s by more acrylic materials and polyester in more recent times driven by a focus on the environment.
These arms provide extra support and stability which some owners prefer in windy areas, and increase the awning’s versatility by making the attachment of certain accessories available.
