The Evo Pivot Arm Awning projects the fabric off the window via a set of arms. This allows sun to be controlled through the angle or pitch, and also allows for airflow underneath as the awning is not fitted directly to the window. Windows can remain open when the awning is in use. The Evo Pivot Arm Awning has a heavy-duty contemporary design and is ideal for larger windows. The front rail has been designed to have the same design curve as the straight drop bottom rail, creating consistency across the Evo range. During winter there’s an immediate reduction in radiant heat loss to the cold window glass, and people feel warmer. Here’s how it works: All people and objects give off and receive radiant heat. When significantly more is given off than they get back to cold glass, it can feel like a chilly draft, even if the window is tightly sealed. When people lose enough radiant heat to feel uncomfortable, they will typically turn up the thermostat, consuming energy resources and adding utility costs – but a well-insulating shade can counteract all this.
