Rotatable cladding panel of space framed triangular section - has translucent sheet and inclined blades on outer and inner sides respectively for winter lighting and summer ventilation

摘要

The rotatable cladding panel has a space frame equilateral triangular cross section, and is used on building facade or roof surfaces to allow max ingress of natural light during winter. The panels are self-supporting being mounted on stub-axles at each end and may be operated by rams with radius arm to a common con-rod. The external face may comprise a bi-walled translucid cladding, the panels including edge mounted compressible seals which are effective at closure. The rear face of each panel may constitute a venetian blind with parallel blades at a fixed inclination allowing winter sunlight ingress and diffusing summer sunlight.
