Simplex Construction for skylights
offers the same advantages in skylight construction that it
does in sidewalk lights. But its greatest point is the fact
that there is so large a glass surface to transmit the light.
Because of the strength of the SIMPLEX the need of carrying
beams is lessened and the lighting is correspondingly
increased.
SIMPLEX is one ideal roof for the
train sheds of depots form, on account of the under layer
of cement there is no exposed metal surface to be corroded
with the gases from the locomotives. And its lightness and
strength give the greatest lighting area.
The big Union Depot at Kansas City,
Mo., is being equipped with about four acres of SIMPLEX
skylights and sidewalk lights. On the Michigan Central Depot
at Detroit, Mich., a large quantity of SIMPLEX sidewalk lights
were installed.
For skylights the glass tiles are
made six inches square on the face so that there will be as
much lighting space as possible.
