SUGGESTIONS
TO ARCHITECT
AND
ENGINEERS.
Our Mr. Maltby has devoted the past twelve years exclusively to the business of lighting buildings through Prismatic Glass, and he feels qualified to offer the following suggestions to architects and engineers:
Results from Prismatic Glass depend entirely upon the angle and quality of prisms used; therefore, after deciding upon the style of prism required (see condensed specification above) it is important to specify that it be furnished and installed by a Prism Glass Company which makes this work its exclusive business, and name the make or makes that will be acceptable to you. Simply specifying Prismatic Glass permits any glass with a pronounced corrugated surface to come within the specifications.
We earnestly solicit the privilege of being included in your specifications.
Upon request, we will send, at our expense, an expert or more detailed information to assist in laying out the prism work for any particular problem. No one concerned is more interested than we in the entire success of an installation of Maltby Prisms.
