2. Presence and functioning of weep system.
3. Minimum required face or edge clearances.
4. Minimum required bite.
5. Effective sealing between joints of framing members.
B. Proceed with installation only after unsatisfactory conditions have been corrected.
3.2 PREPARATION
A. Clean glazing channels and other framing members receiving security glazing immediately
before glazing. Remove coatings not firmly bonded to substrates.

sealant width. With glazing tape, use thickness slightly less than final compressed
thickness of tape.
G. Provide edge blocking where indicated or needed to prevent security glazing from moving
sideways in glazing channel, as recommended in writing by security glazing manufacturer and
according to requirements in referenced glazing publications.
H. Set security glazing in each series with uniform pattern, draw, bow, and similar characteristics.

3.4 TAPE GLAZING
A. Position tapes on fixed stops so that, when compressed by security glazing, their exposed
edges are flush with or protrude slightly above sightline of stops.
B. Install tapes continuously, but not necessarily in one continuous length. Do not stretch tapes to
make them fit opening.
C. Cover vertical framing joints by applying tapes to heads and sills first and then to jambs. Cover
horizontal framing joints by applying tapes to jambs and then to heads and sills.
D. Place joints in tapes at corners of opening with adjoining lengths butted together, not lapped.
Seal joints in tapes with compatible sealant approved by tape manufacturer.
E. Do not remove release paper from tape until just before each glazing unit is installed.
F. Apply heel bead of elastomeric sealant.

dense compression gaskets formed and installed to lock in place against faces of removable
stops. Start gasket applications at corners and work toward centers of openings.
H. Apply cap bead of elastomeric sealant over exposed edge of tape.
3.5 GASKET GLAZING (DRY)

and press firmly against soft compression gasket by inserting dense compression gaskets
formed and installed to lock in place against faces of removable stops. Start gasket
applications at corners and work toward centers of openings. Compress gaskets to produce a
weathertight seal without developing bending stresses in security glazing. Seal gasket joints
with sealant recommended by gasket manufacturer.
D. Installation with Pressure-Glazing Stops: Center security glazing in openings on setting blocks
and press firmly against soft compression gasket. Install dense compression gaskets and
pressure-glazing stops, applying pressure uniformly to compression gaskets. Compress
gaskets to produce a weathertight seal without developing bending stresses in security glazing.
Seal gasket joints with sealant recommended by gasket manufacturer.
E. Install gaskets so they protrude past face of glazing stops.
3.6 SEALANT GLAZING (WET)
A. Install continuous spacers, or spacers combined with cylindrical sealant backing, between
security glazing and glazing stops to maintain face clearances and to prevent sealant from
extruding into glazing channel and blocking weep systems. Secure spacers or spacers and
