For windows facing east or west, the size of the drop is recommended to be 65-75% for optimal performance. For a south-facing window, the drop can be as low as 45-60% as less coverage is needed due to the angle of the sun.
The type of awning is also a very important point to consider. Roll up and retractable awnings allow you to control the awnings, meaning you can gain maximum natural sunlight during winter if you choose to.
Retractable awnings are therefore especially appropriate for patios or decks, allowing you to adjust it when not in use. With the use of motors and switches, retracting the awning becomes a breeze. Especially advanced models have automatic sun and wind sensors, meaning you don’t need to tinker with it every time the weather changes.
Freestanding awnings are also commonly used for patios, decks or terraces. They effectively segment a space, which is great if you would like to designate a separate area to the BBQ, for example. Businesses also love free-standing awnings, as they can be used to double up as an advertisement.
