2.4.1
Putty and Glazing Compound
Glazing compound shall conform to ASTM C 669 for face-glazing metal sash.
Putty shall be linseed oil type conforming to CID A-A-378for face-glazing
primed wood sash. Putty and glazing compounds shall not be used with
insulating glass or laminated glass.
2.4.2
Glazing Compound
ASTM C 669. Use for face glazing metal sash.
Do not use with insulating
glass units or laminated glass.
2.4.3
Sealants
Provide elastomeric [and structural] sealants.
2.4.3.1
Elastomeric Sealant
ASTM C 920, Type S or M, Grade NS, Class 12.5, Use G. Use for channel or
stop glazing [wood] [and] [metal] sash. Sealant shall be chemically
compatible with setting blocks, edge blocks, and sealing tapes[, with
sealants used in manufacture of insulating glass units] [, and with plastic
sheet]. Color of sealant shall be [as selected] [gray] [white] [_____].
2.4.3.2
Structural Sealant
ASTM C 1184.
2.4.4
Preformed Channels
Neoprene, vinyl, or rubber, as recommended by the glass manufacturer for
the particular condition. [Channels for bullet-resistant glass shall be
synthetic rubber, ASTM C 864, not less than 6 mm 1/4 inch thick and
sufficiently resilient to accommodate expansion and contraction while
maintaining a vaportight seal between glass and frame.] [Channels shall be
chemically compatible with plastic sheet.]
2.4.5
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. Tapes
shall be chemically compatible with the product being set.
2.4.6
Setting Blocks and Edge Blocks
Neoprene setting blocks shall be dense extruded type conforming to ASTM D
395, Method B, Shore A durometer between 70 and 90. Edge blocking shall be
Shore A durometer of 50 (+ or - 5). Silicone setting blocks shall be
required when blocks are in contact with silicone sealant. Profiles,
lengths and locations shall be as required and recommended in writing by
glass manufacturer.
2.4.7
Glazing Gaskets
Glazing gaskets shall be extruded with continuous integral locking
projection designed to engage into metal glass holding members to provide a
watertight seal during dynamic loading, building movements and thermal
