holes, notched and edged-finished depending upon the requirements and, due to advanced research and experimentation, shapes formerly thought impossible can now be achieved both in single and laminated sheets of glass. It is produced in thicknesses from .042 of an inch up to one and one-half inches in single sheets, while in laminated form even greater thicknesses are available. Although it possesses surprising flexibility and elasticity, especially when tempered, it is actually fatigue-proof*that

is, after being flexed, a light of glass always maintains exactly its original shape. The tempering process which gives glass its great strength also substantially increases its resistance to thermal shock. Thus, glass can be made to withstand continuous temperatures of

6500 F and an instantaneous thermoshock of 4000 to 4500 F.

First step in this theatre's remodeling program was the installation of modern, all-glass doors. The

only to keep out the weather is definitely a thing of the past. Product designers nowadays are able to find in glass a combination of advantages and properties found in no other single material in existence. The old weaknesses of glass as a design material have been overcome by brilliantly successful research and by sweeping manufacturing improvements. And a host of new, appealing qualities have been added to glass which help to make it the ideal material for scores of practical, attractive, and economical product applications. Specified by leading architects, experienced in designing new theatres and remodeling out-dated ones, are many glass products.

Structural Glass

There is, for example, structural glass, an opaque wall surfacing material widely used in both interior and exterior work with great success. This product comes in a wide variety of colors and has been used in an infinite number of applications. It is particularly useful where its sanitation qualities and ease of maintenance make it ideal for walls in restrooms, corridors and lounges. In appearance it has soft yet brilliant qualities which are distinctive and satisfying.

Glass Block

Included in this structural usage, is the glass block, a product with limitless decorative possibilities. These hollow glass units, adaptable to all types of architecture, are sealed at high temperature and thus have great insulating value. Actually, the insulating value of a single cavity glass block is better than that of an eight-inch brick*more than twice that of ordinary windows. The double cavity blocksewith a fibrous glass screen inserteprovide even better thermal insulation value. Consequently, heat loss is less in wintereheat gain less in summer with a resultant lightening of the load on heating and air conditioning equipment. The light which streams through the block is full daylight tone, requiring no special consideration in the matching of colors, either for decoration or production uniformity. They reduce outside noise and eliminate unsightly views, while at the same time they are easy to clean, assure absolute privacy and require a minimum of maintenance, since they are not easily marred or broken.

Glass Doors

Tempered glass doors are almost standard equipment in the up-to-date theatre since they permit uninterrupted Visual display from lobby to foyer. Made of specially tempered glass, usually three-quarters of an inch in thickness, they are four to five times as strong as regular plate glass of the same thickness and are many times more resistant to impact and shock. Usually they are hung without frames of any description and in many cases are hinged with a special device that automatically opens the door when the handle is touched. The fact that this glass may bo dece (irzttivcly etched improves the application immeasurably.
