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.
 glazing
161
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.
Float glass
162
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
Tempered glass
163
What is another name for float glass
Annealed glass
164
What is a disadvantage to tempered glass
It must be ordered to the exact size requirement for the final installation because once it is tempered it cannot be cut drilled or deeply etched. In addition tempering may produce light distortions in the field of the glass
165
 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.
Laminated glass
166
As a mesh of wire embedded in the middle of the sheet. The surface can either be smooth or a pattern. This type of glass is used primarily for fire rated assemblies if it is not in a hazardous location. This type of glass cannot be tempered and does not qualify as safety grazing for hazardous locations.
Wire glass
167
The specialty glass is made by passing a sheet of molten glass through rollers on which the desired pattern is pressed, which may be low on one or both sides. Vision through the panel is diffused but not totally obscured the degree of diffusion depends on the type and depth of the pattern.
Patterned glass
168
What are the five types of fire rated glass
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
General term for a type of glazing that changes from either a dark tent or milky white OPEC to transparent with the application of an electric current. When the current is turned off the glass either darkens returns white. There are three distinct types of this glazing currently on the market.
Electro chromatic glazing
170
What are the three types of electro chromatic glazing
Electro chromatic glazing
Suspended particle device SPD
Polymer dispersed liquid crystal film
171
Uses an inorganic ceramic 10 film coating on glass and can be manufactured to range from transparent to heavily darkened or tinted. However, it is never OK, so it cannot be used for privacy glass. It is intended for control of like, ultraviolet energy, and solar heat gain. The amount of tinting is not just in on or off condition, it can be controlled with a simple rheostat switch
Electro chromatic glazing
172
Uses a proprietary system in which light absorbing microscopic particles are dispersed within a liquid suspension film which is in Sandwich between two pieces of transparent conductive material. Your parents of the product can range from cleared partially darken to totally OK, so it can be used for privacy as well as for like control an energy conservation. They can also be very very controlled with a rheostat.
SPD glazing
173
Is fabricated by placing the polymer film between two pieces of glass. The transparency can range from transparent to cloudy white. And its translucent state, it offers total visible visible privacy if it still allows for a significant amount of light to pass through, so it cannot be used for exterior light control. All of the types of electro chromatic glazing are very expensive, but the first two types to offer the potential for significant energy savings in the range of 20 to 30%.
Polymer dispersed liquid crystal film glazing
174
What type of glass is required for interior fire window assemblies
1/4 inch wire glass installed in steel frames or buy approved fire resistant rated glazing. The maximum glazed area cannot exceed 25% of the length of the common wall with any room. Special fire resistant rating glazing is not subject to this 25% limitation because it is tested as a wall assembly, not as an opening assembly.
175
What types of glazing are considered safety glazing
