We were thrilled to be a part of this project at the Crane Country Day School in Montectio, CA. This is the Hunter Douglas Contract Solar Control division's fully retractable angle top bottom up shades.

This was a great application of the Hunter Douglas Contract Solar Control Cloudrail system using solar screen shade cloth stretched over frames to act as a non operable shade.
