Materials and Methods of Installation
Comply with the manufacturer's warranty and written instructions, except as
indicated. Install units with the heat-absorbing glass to the exterior.
Secure glass in place with bolts and spring clips. The minimum clearance
between bolts and edge of glass unit shall be 4.75 mm 3/16 inch.
The
glass shall be edged with 4.75 mm 3/16 inch thick continuous neoprene,
vinyl, or other approved material. Trim edging after installation. The
channel shapes or strips shall be firmly held against the glass by the
spring action of the extruded metal moldings. Resilient setting blocks,
spacer strips, clips, bolts, washers, angles, applicable glazing compound,
and resilient channels or cemented-on materials shall be as recommended in
the written instructions of the glass manufacturer, as approved.
3.3.2
Tolerances and Clearances of Units

glass. Springing, twisting, or forcing of units during setting will not be
permitted.

CLEANING
Clean glass surfaces and remove labels, paint spots, putty, and other
defacement as required to prevent staining. Glass shall be clean at the
time the work is accepted. [Clean plastic sheet in accordance with
manufacturer's instructions.]

PROTECTION
Glass work shall be protected immediately after installation. Glazed
openings shall be identified with suitable warning tapes, cloth or paper
flags, attached with non-staining adhesives. Reflective glass shall be
protected with a protective material to eliminate any contamination of the
reflective coating. Protective material shall be placed far enough away
from the coated glass to allow air to circulate to reduce heat buildup and
moisture accumulation on the glass. Glass units which are broken, chipped,
cracked, abraded, or otherwise damaged during construction activities shall
be removed and replaced with new units.
