Purpose
An awning and canopy purpose would satisfy any one or all of the following functional objectives: Energy savings; weather protection (Sun, rain, snow, sleet, hail, and wind), identification, or aesthetics
Style, Configuration, Color
Most awnings and canopies consist of fabric stretched over and secured to a fixed metal frame that is secured by laces, screws or staples. These frames may be welded, bolted or otherwise connected. Other awnings and canopies that consist of individual fabric panels can be attached using the staple in method. Still other awnings and canopies consist of rollers and lateral arms that can be retracted manually or automatically. It should be noted, however, that the possible combinations of styles, configurations and colors are limitless.
Frame Styles • Concave • Dome
• Elongated Dome • Quarter round/Convex • Lateral Arm/Retractable • Round top Canopy • Traditional Awning • Peaked Canopy • Etc.
Size and Fit
The size of an awning is determined by its length, width and projection from the building to which it is attached. Other aspects of size include clear height (underneath), rise (pitch) of roof and post or rafter spacing. These features are usually important to those involved in the planning and review process.
The fit of an awning is determined by the interfacing of its frame with other connecting structures (most often a building, but frequently the ground or a concrete slab on the ground). In the case of a building, it is important to coordinate the appropriate parts of the awning frame with structural members in the building so that loads are transmitted properly. Strength- After stable configuration has been established for an awning design frame, members should be chosen for strength consistent with the amount and type of stress imposed on them. The most common types of stress are tension, compression, bending and shear.
Frames fixed vs. Moveable
Frame systems are recommended by the manufacturer, according to personal preference and regional norms. Frames are joined by special fittings or welding according to manufacturer recommendations and regional variations.
A fixed awning frame cannot be deployed from a stowed position and vice a versa. A moveable awning can be stowed against the building to which it is attached. The standard lateral arm and drop arm awnings are examples of moveable awnings.
