LUXFER PRISM
SHEET. |
The proper daylight illumination
of mills, factories, warehouses and school buildings is a matter of
importance to the architect, owner and tenant of such buildings. This
can be readily accomplished by equipping the windows with Luxfer Sheet
Prisms (Fig. 19).
Luxfer Sheet Prism glass is made under United
States Letters Patent, and comprises various angles of prisms. The
lighting results obtained from any prism glass depends on the angle of
prism used, and, therefore, should be scientifically prescribed in
every case.
|
| INSTALLATION. |
This glass is made in sheets and can
be cut to any size desired up to 84 inches wide by 60 inches high, and can
be installed in ordinary window sash at a price which will justify the use
of large quantities in any building. A wonderful increase in the
illumination is obtained and a consequent saving of from twenty-five to
fifty per cent. in the cost of artificial lighting is effected.
