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.

When you buy roof-lights and vault-lights you pay for the square foot of materials—but what you really want is daylight, efficiency, and economy.
Keppler Glass Constructions put the emphasis on daylight, efficiency, and ultimate economy. They admit as much as 40 per cent more daylight than ordinary constructions. They have an all-glass undersurface and appear from below as one large light source instead of a number of small units. No exposed metal parts—no painting or upkeep is needed.
They can be assembled right at the job or furnished complete in
