Keppler Glass Constructions Canadian Centre for Architecture via The Internet Archive 80MB: pdf	Translucent but not transparent · Fig. 1. Keppler Floor, Roof and Vault Light Constructions are composed of translucent glass units, supported by reinforced concrete. They have a large glass area above, and an all-glass undersurface, which admits and distributes the maximum of light. The concrete frame-work, reinforced with rods, gives great supporting strength without cutting off the light. Fig. 2. Cross section of Keppler Floor Light, showing reinforced concrete construction and all-glass undersurface. The concave sides of the glasses are painted white to secure total reflection of light rays striking the concrete ribs.
