The process of installing glass in framing as well as installing the framing itself. There are a number of types of glass that are available for interior use.

A

 glazing

161
Q

Standard type of glass used in common windows and other applications were additional strength or other properties are not required. For interior use, it is employed in small openings or wear safety glazing is not required.

A

Float glass

162
Q

Produced by subjecting annealed glass to a special heat treatment. This class is about four times stronger than a nail glass of the same thickness. In addition to its extra strength for normal glazing, this type of glass is considered safety glass, so it can be used in hazardous locations. If it breaks, it falls into thousands of very small pieces instead of dangerous shards. This type of glass or interior uses commonly 1/4 inch thick

A

Tempered glass

163
Q

165
Q

 pieces of two or more layers of glass bonded together by an inter-layer of polyvinyl butyryl. The glass can be clear or tinted float glass, tempered glass, or heat strengthened glass. When exceptional impact or ballistic resistance is required, heat strengthen the glass can enclose one or more layers of poly carbonate Laminated with inter-layers of polyvinyl butyryl or polyurethane. Polycarbonates are thermal plastic resin’s that are dimensionally stable and have high impact. When this type of glass is broken, the inner layer holds the pieces together even though the glass itself may be severely cracked.

A

Wire glass

Clear ceramic glass that has higher impact resistant then wire class and low expansion coefficient. It is available with a one hour rating in size is up to 1296 in.² and with three hour rating inside is up to 100 in.². They are eliminated assemblies that are up to two hours in our impact safety rated.

Special, tempered fire protective glass. It is rated at a maximum of 30 minutes because it cannot pass the hose stream test, but it does make the impact standards for both a NSIZ 97.1 and 16 CFR120 one.

This type consists of two or three layers of tempered glass with a clear polymer gel between them. Under normal conditions, this class is transparent, but when subjected to fire, the gel foams interns opaque, this retarding the passage of heat. This product is available with 30 minute, 60 minute, and 90 minute ratings, depending on the technician number of glass panes used.

This type of glazing is glass block. However, not all glass block is rated. The glass block must have been specifically tested for use in fire rated openings and approved by the local authority having jurisdiction

169

A

Parallel arrangement

268

A

Crisscross spiral arrangement

269
Q

Hoisting and lowering devices, very much like small elevators, used to vertically support materials and supplies, but never people. They are distinguished from freight elevators by limitation‘s found in the elevator safety, namely, car platforms may not exceed 9 ft.² in size and work in a car how to see for feet. But these are quite small and their capacity never exceeds 500 pounds. They may be automatically powered, or they may be manually operated by polling ropes. In either case, they have very few safety features, as they are principal purpose is material handling
