Exterior patio shades are available with manual control in widths up to 16 feet. Chad Blain got his arm workout with these Summit shades from Corradi. We've slowly been adding shades to this restaurant's patio seating area to increase comfort for afternoon and evening diners. The SheerWeave 4600 fabric from Phifer blocks 97% of the light and glare, but still offers a great view .... of the parking lot. It's more about comfort than view in this situation.
