Terrace awnings are a long‑term investment. A properly selected awning will provide sun and rain protection as well as operational ease and convenience. Before selecting an awning system, it is advisable to observe the position of the sun on the elevation where the awning is to be installed. This will help determine the proper width and depth of the awning. The height at which the awning is to be installed should also be taken into account as this will influence the angle of the awning. Determining these parameters in advance facilitates selection of the most appropriate awning system.
