ANNEALED GLASS
Standard float glass when broken it will break in large sharp shards.
ANSI Z26.1
"American National Standards Institute glazing standard. This standard
for Safety Glazing Materials became the accepted, uniform code for the
specifications and testing of motor vehicle glazing material. The code
was compiled by many organizations, including the automotive industry,
glass manufacturers, and the Society of Automotive Engineers."
ASTM C1048
Specification for heat-treated glass which contains an intermediate
level of temper.
CAD
Computer-aided Design is software used to design products.
CLEAR GLASS
SIZE
The measurement of the viewing area of the glass inside the frame.
CERAMIC FRIT
Particles of glass applied to the edge of a piece of glass. Frit has
a low melting point that permanently bonds to the glass during the tempering
process. Attention to blackout and adhesion to glass is tested.
FRA
Federal Railroad Administration
FRIT
Blacked out perimeter of a piece of glass to prevent UV light from damaging
the adhesive holding the glass.
GLAZING
The act of installing material, glass or other transparent material
within a frame.
HEATED GLASS
Electrically Heated - fine, nearly invisible, conductive wires laminated
between 2 or more panes of glass. A low voltage is passed through them
to create a heated surface. Voltages range from 12V dc to 450V ac.
HEAVY-DUTY
Windows with a glass thickness 15mm and over. This also includes glass
laminates (i.e. 19mm/10mm=29mm overall thickness).
ISO Certification
An internationally recognized quality standard. The International Organization
for Standardization is based in Switzerland and is a network of national
standards institutes. The ISO 9001:2000 quality standard is perhaps
the most well known quality standard in the world.
LAMINATED GLASS
2 or more la /A GLASS
Refers to overall thickness of multiple glass makeup.yers of annealed
or tempered glass bonded to an intermediate layer of PVB plastic film.
If it breaks, pieces of glass are adhered to the PVB film, therefore
reducing the likelyhood of injury. This type of safety glass is also
used as a sound barrier.
RADIUS CORNERS
An arc or bend in the corner of a fabricated window or door.
SAFETY GLASS
Glass that is treated to prevent injury in the event it is broken. Tempered
glass, when broken, will break into tiny pieces and laminated glass
will crack without breaking apart into dangerous shards. Laminated usually
stays in the opening.
TEMPERED GLASS
Glass is heat treated and then cooled in a controlled enviornment to
improve tensile strength. Tempered glass shatters into many small pieces
when under stress.
TERMINAL BLOCK
Plastic block containing brass/steel connectors to join the heated glass
grid to the external power supply.
