- Provide ultraviolet protection. Sheers and vanes combine to provide up to 88 percent ultraviolet protection with the shading down and the vanes open; and 99 percent with the vanes closed.
- Enhance natural daylighting. Sheers disperse sunlight deep into the room, reducing the need for electric lights to brighten rooms in winter, spring, summer and fall.
- Reflect solar heat. Exterior white sheer and vanes reflect the sun’s heat, reducing solar heat gain.
