reflective or tinted films. For insulated glass
units, apply film to the interior (room) side only.
Other applications have not been tested. Tests show
that film applications to insulated glass units
offer more protection for occupants than
applications on single sheets of glass. When more
than one type of film application is used for a
project, indicate the application to be used on the
door and window schedules or elevations.
**************************************************************************
Fragment retention film shall be provided on window and door glass where
indicated. After surface preparation, the fragment retention film shall be
applied in accordance with the manufacturer's recommendations and
instructions. Film shall be applied to the interior (room) side of the
glass for both single and double glazed sheets, unless otherwise indicated.
Multiple applications of film to achieve specified thicknesses is not
allowed. The film shall not be applied if there are visible dust particles
in the air, if there is frost on the glazing, or if any room condition such
as temperature and humidity do not meet the manufacturer's instructions.
After film application, room conditions shall be maintained as required by
the manufacturer's instructions to allow for proper curing of the adhesive.
3.2.1
Application to New Glass Before Glazing
**************************************************************************
NOTE: Retain this paragraph when film will be
applied to the glass before glazing. This may occur
at the window or door manufacturer's shop or in the
field. Designer will insert a coordinating note
into Section: GLASS AND GLAZING, indicating that
fragment retention film application is a requirement.
**************************************************************************
Fragment retention film shall be applied so that it extends edge to edge of
the glass sheet. The film reinforced glass shall then be set into the
frame with glazing compounds or gaskets as specified in Section 08800
GLAZING. When contact between the glazing compounds and/or gaskets and the
film occurs, the Contractor shall ensure compatibility. The Contractor
shall be responsible for delivery of the fragment retention film to the
appropriate location for application. Fragment retention film application
and curing shall be coordinated with the glass supplier and window or door
manufacturer prior to glazing installation.
3.2.2
Application to Existing Glass Involving Dismantlement
**************************************************************************
NOTE: Retain this paragraph when film is to be
applied to existing glazing where the stops,
compounds, and/or gaskets must be removed to apply
the film edge to edge of the glass sheet.
Dismantlement is recommended for glazed openings
with removable stops and removable reusable gaskets.
Removable gaskets include vinyl and rubber channels
or beads and extruded aluminum beads. Dismantlement
may be too expensive for openings glazed with
compounds. This expense is due to the increased
labor, increased risk of breakage, and increased
cost of replacing compounds because most compounds
