1.4 QUALITY ASSURANCE:

A. Failure Criteria: Not limited to the following:

1\. Cracking.

1.5 PROJECT/SITE CONDITIONS:

A. Environmental Considerations: Do not start exterior or unheated
interior glazing work until the outdoor temperature is above 40 degrees
F and rising, unless approved provisions are made to warm the glass and
rabbet surfaces. Provide sufficient ventilation to prevent condensation
of moisture on glazing work during installation. Do not perform glazing
work during damp or rainy weather.

[PART 2: PRODUCTS]{.underline}

2.1 MATERIALS:

A. Wire Glass: Clear, diamond pattern, \[burlap pattern translucent\]
polished both sides, 1/4 inch thick. Glass for fire doors shall conform
to NFPA 80.

B. Setting Materials: Shall be the types required for the applicable
setting method specified in the FGMA Sealant Manual, unless specified
otherwise herein. Do not use metal sash putty, nonskinning compounds,
nonresilient preformed sealers, or impregnated preformed gaskets.
Materials which will be exposed to view and unpainted shall be gray or
neutral color. Surfaces to be sealed must be completely clean and dry.
Check sealant manufacturer\'s recommendations for proper cleaning
procedures.

1\. Elastomeric Sealant: Use for channel or stop‑glazing wood and metal
sash. Sealant shall be chemically compatible with setting blocks, edge
blocks and sealing tapes. See Section 07920 ‑ Sealants and Caulking for
acceptable sealant.

2\. Preformed Channels: Neoprene, vinyl, or rubber, NAAMM SG‑1, as
recommended by the glass manufacturer for the particular condition.

3\. Sealing Tapes: Preformed, semisolid, polymeric‑based material of
proper size and compressibility for the particular condition. Use only
where glazing rabbet is designed for tape and tape is recommended by the
glass or sealant manufacturer. Provide spacer shims for use with
compressible tapes. Edges of the wire glass must be completely covered
with tape to protect against sealants and water. Only protective tapes
will be permissible. Do not use rubber impregnated or friction tape.
Oils and solvents penetrate tapes of this kind.

4\. Setting Blocks and Edge Blocks: Neoprene of 70 to 90 Shore \"A\"
durometer hardness, chemically compatible with sealants used, and of
sizes recommended by the glass manufacturer, set at 1/4 points, minimum
4 inches long each. Do not use lead.

5\. Accessories: As required to provide a complete installation,
including glazing points, clips, shims, angles, beads, and spacer
strips. Provide noncorroding metal accessories. Provide primer‑sealers
and cleaners as recommended by the glass and sealant manufacturers.

[PART 3: EXECUTION]{.underline}

3.1 PREPARATION:

A. Precautions and Procedures: Determine the sizes to provide the
required edge clearances by measuring the actual opening to receive the
glass. Edge to frame clearance 1/4 inch; face clearance 1/8 inch. Leave
labels in place until the installation is approved. Securely fix movable
items or keep in a closed and locked position until glazing compound has
thoroughly set. Glass breakage from thermal shock may occur if heat from
any source is localized on the glass surface. Baffle heat runs so that
the heat is directed away from the glass.

3.2 INSTALLATION:

A. Glass Setting: Items to be glazed shall be either shop or field
glazed using glass of the quality and thickness specified or indicated.
Preparation and glazing, unless otherwise specified or approved, shall
conform to applicable recommendations in the FGMA Glazing Manual and
Sealant Manual. Wood doors and wood windows may be glazed in conformance
with one of the glazing methods described in the standards under which
they are produced, except that face puttying with no bedding will not be
permitted. Handle and install glazing materials in accordance with the
manufacturer\'s instructions. Use beads or stops which are furnished
with the items to be glazed to secure the glass in place. A positive
seal shall be provided between the glass and metal or wood.

3.3 CLEANING:

A. Requirements: Thoroughly clean glass surfaces and remove labels,
paint spots, putty and other defacement. Glass shall be clean at the
time the work is accepted. Cracked, broken, or imperfect glass shall be
replaced at the expense of the Contractor. Do not paint signs or affix
cardboard, paper or tape to the glass.

[PART 4: MEASUREMENT AND PAYMENT]{.underline}

4.1 METHOD OF MEASUREMENT:

A. Units: The work described in this section will not be measured for
payment.

4.2 BASIS OF PAYMENT:

A. Payment: No direct payment for the work described under this section
will be made. The Contractor shall include consideration for this item
in the bid price for other items of the Contract.
