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

When you buy roof-lights and vault-lights you pay for the square
foot of materials—but what you really want is daylight, efficiency,
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
Keppler Pre-assembled Panels
These panels are built in our shops to fit

trouble. Any mason can set them in their openings and make them
