Awnings are available in a wide range of styles and configurations, from simple window coverings through to large outdoor settings. retractable awnings (Kassettenmarkise) are some of the most popular designs used in modern times, and are often installed so that people have some control over the weather conditions. Retractable awnings allow people to manipulate the level of shade through the use of retractable awning arms and torsion bars. There are a variety of different retractable awning designs on the market, including lateral arm awnings and side or drop arm awnings. Retractable awnings have been popular in parts of Europe for some time now, and are just starting to become more popular in the United States.
There are many benefits to retractable awnings when compared to fixed arm awnings, with retractable designs generally allowing greater freedom in terms of customisation. Lateral arm awnings are one version of retractable awnings, being a modern version of the old store front crank-up awnings that existed in the 19th century. Lateral arm awnings use tension arms and a specially designed roller bar which is supported by a torsion bar, with the awning motor generally fitting inside of the roller tube. While it is still possible to purchase hand cranked awnings in the 21st century, the vast majority of awnings in this style now feature internal motors. In most cases, the motor comes with a built in receiver which can be operated by remote control or through a wider home automation system.
Other than the popular lateral arm configurations, side or drop arm awnings are the other popular type of retractable awning design that is used in modern times. Side or drop arm awnings are typically used above a window as a way to provide shade and privacy, and feature a roller tube at the top and spring loaded side arms that work with either a motor, a tape pull, or a crank mechanism. This style of awning has a traditional appearance that is still widely used on historical buildings. Side or drop arm awnings are available either with or without sides, and can be installed above a majority of window settings. Whether they are being used above windows or to create outdoor living areas, retractable awnings offer a number of advantages over non-retractable awning structures.
