DAYLIGHTING
FROM THE FRONT
The approved modern store front is constructed as follows:
Plate glass is set in patent corner clamps or posts, for approximately two-thirds of height, to a transom bar. Above this bar panels of Luxfer 4-in. pressed crystal prisms are set in the same manner as ordinary glass.
The result is that the upper part of the show windows, which are useless for display purposes, in fact are a hindrance to artistic trimming, are used to flood the store with daylight.
In remodeling, where the present front has plain glass transoms it is a very simple matter to install Luxfer panels in place of the glass already set with the same result as above noted.
In remodeling, where the front is of the oldfashioned recessed style with heavy pillars, Luxfer panels may be set flush with the outside of the columns with pleasing effect. The results in such a case are also very satisfactory, the light being thrown back through the window, which remains intact.
FROM THE REAR
Where the building has no alleyway but is built against the building in the rear, Luxfer Extension Skylight Prisms are used.
These pressed crystal prisms are 12 × 13 inches square and are set in ordinary skylight frames. The daylighting result from this installation is marvelous, and no room that is dark in the rear need be so longer.
In any case where the old-fashioned form of skylight is in use, the cost of Luxfer can be saved in your lighting bills for six months, by changing the present glass for Luxfer Prisms.
Our installation is guaranteed leak-proof for two years. It is the only installation approved by the Board of Fire Underwriters.
Where there is an alleyway, but so narrow as to cut off all light falling at an angle, we install our Luxfer Prism Canopies, which are our crystal prism panels set at an angle, after the manner of awnings. These receive the light directly from above and are attached to the building by metal brackets.
