In form and construction
of PASCHALL SYSTEM of Skylight Installation is the same
as the sidewalk lights. The only difference is that each
glass tile has over two times the light area. This gives
the entire installation a much greater lighting area, but
it would not be adaptable to the sidewalk on account of
the difference in the possible loads.
With the bars set farther apart,
the glass larger and the oating of concrete not so heavy,
the entire weight of the skylight construction is much
lighter thyan the sidewalk form. Thus we are able to
span any reasonable distance without the use of any
intermediate supporting beams. This construction is
available for use in any type of skylight
For the bottom of light courts
in office buildings or stores; for lean-to roofs; for
roofs of public buildings; for glass domes; for roof
lights of all kinds, the PASCHALL is the ideal installation
as it combines the greatest strength with the lightness in
weight and the maximum glass area, having the fewest
supporting beams.
The metal grids can be supplied
in natural iron, galvanized or painted finishes as
desired. Spans as long as 10 feet can be installed so
that the amount of supporting structure is materially
less than in every other form. This means a saving in
structural expense as well as in ancrease in glass area.

The glass is protected in the
same way as in the sidewalk, by means of the countersunk
Plastic Malleable coating, against breakage by expansion
pressure.
