C/S Airfoil^®  Typical Design Options

Horizontal Canopy Shading

Vertical Shading

C/S Airfoil^® based horizontal canopy shading designs are ideal for both new and existing construction. They provide effective shading while maintaining unobstructed views. Projection and blade size may be varied to suit the project requirements.

This design of sunscreen is most effective for use on elevations facing from South-East through to South-West.

During summer months the building will be shaded from harsh high intensity direct sunlight, while gentle diffused light will still be allowed into the building. During winter months, however, the lower altitude of the sun will allow direct sunlight under the canopy into the building, providing limited solar gain to supplement the building's heating system.

C/S Airfoil^® vertical solar shading is the perfect alternative where greater control is required over direct sunlight. The choice of blade orientation, either horizontal or vertical, is largely determined by a combination of form and function.  The form being architectural preference, the function being the amount of sun cut-off required and the building orientation.

Vertically orientated blades are typically used on elevations facing due East or due West, where a problem exists with glare from low angle direct sunlight. In this instance, depending on blade spacing, a 90° blade mounting angle will be sufficient to eliminate virtually all direct sunlight, while allowing an optimum field of vision and diffused light to be reflected back into the building.

Skylight Shading

Roof openings such as skylights are the most practical way of letting in daylight, but also pose the biggest problems with direct solar penetration. Skylight shading formed using C/S Airfoil^® blades help skylights achieve optimum performance by allowing softly diffused light in, while minimising unwanted solar heat gain.

Skylight shading is most effective when installed above the skylight. When installed below, 70% of the solar heat gain will have already entered the building.
