SYSTEM DESCRIPTION
**************************************************************************
NOTE: This specification should be used when glass
may be subjected to the effects of explosives or
projectiles and when protection of personnel from
SECTION 08 87 23.13
Page 3
the resulting glass spalling is required. The film
is most effective when installed on the interior
surface of the glass. Under low blast pressures or
projectile loads, the film may not prevent the glass
from breaking but it holds the glass fragments
together and reduces the destructive capability of
flying glass fragments. Note that testing has shown
that fragment retention film will not necessarily
hold glass fragments together when subjected to very
high blast pressures, and the designer may therefore
want to consider alternate methods for protection of
personnel. The application of film to glass
generally allows projectiles, fragments, or bullets
to pass through; however, the film does reduce
spalling of the glass associated with a projectile
passing through the film.
The application of film to glass provides some
resistance against impacts from hammers, rocks,
clubs, or thrown objects. An impact on the film
reinforced glass creates a hole approximately the
size of the impacting object. Therefore, several
impacts are needed to make a hole large enough for
entry. The use of greater film thickness and/or
factory laminated films provides more resistance
against these impacts.
Tints and reflective films can improve the thermal
energy performance of a building. However, darkly
tinted and reflective films can cause internal heat
buildup and internal stresses in the glass resulting
in a weakened glazing system. If reflective films
are used to reduce visibility into a facility, also
provide curtains or shades for night use because
films are not reflective when the light level on the
exterior side of the film is less than that on the
interior side.
**************************************************************************
1.2.1
General Requirements
The applied fragment retention film shall be clean and free of peeling,
splitting, scratches, creases, wrinkles, discoloration, and foreign
particles. The film application shall be free of air bubbles after 30
days. Fragment retention film shall not show signs of waviness and
distortion at the time the work is accepted. This determination shall be
made by the unaided eye (except for corrective prescription glasses), when
the film is viewed from a distance of 3 m 10 feet from the interior room
side at angles up to 45 degrees when looking at a clear or uniformly
overcast sky. Unacceptable fragment retention film applications shall be
removed in accordance with manufacturer's instructions and new film applied.
1.2.2

2.1
PRODUCTS
STANDARD PRODUCTS
Provide fragment retention film which is the standard product of a
manufacturer regularly engaged in the manufacture of such products and that
essentially duplicate items that have been in satisfactory use for at least
2 years prior to bid opening.
2.2
FRAGMENT RETENTION FILM
**************************************************************************
NOTE: Indicate windows and doors requiring film on
the window and door schedules or window and door
elevations of the drawings.
The film is available in 0.05 mm 0.002 in., 0.10 mm
0.004 in., 0.18 mm 0.007 in., 0.20 mm 0.008 in.,
0.25 mm 0.010 in., and 0.30 mm 0.012 inch
thicknesses. A minimum thickness of 0.10 mm 0.004
inch film is acceptable for fragment retention. The
use of greater than 0.10 mm 0.004 inch film
thickness and/or factory laminated films of 0.10 mm
0.004 inch or greater may provide more protection
for occupants from flying fragments of glass but may
not be warranted for low blast pressure. The
designer must investigate window frames and building
components adjacent to the glazed opening for
transfer of the blast load when using 0.18 mm 0.007
inch and thicker films.
The properties of fragment retention film and/or the
adhesive may change over time, effecting the film's
capacity to retain fragments. Testing has shown the
film retains fragments up to 7 years of use.
**************************************************************************
Fragment retention film shall be polyester, polyethylene terephthalate, or
a composite, optically clear and free of waves, distortions, impurities,
and adhesive lines. The film may be a single layer or laminated.
Lamination of the film shall only occur at the factory of the fragment
retention film manufacturer. The film shall include an abrasion resistant
coating on the surface that does not receive the film adhesive. Fragment
retention film shall be a minimum thickness of [0.10] [0.18] [0.25] mm
[0.004] [0.007] [0.010] inch and shall be [clear] [tinted] [reflective].
The film shall be supplied with an optically clear weatherable pressure
sensitive adhesive. The adhesive shall contain ultraviolet inhibitors to
protect the film for its required life and shall limit ultraviolet
transmission to not more than 8 percent of the radiation between 300 and
380 nanometers. The adhesive shall not be water activated. A water
soluble detackifier and/or release liner may be incorporated over the
adhesive to facilitate film application. The adhesive shall be 90 percent
cured within 30 days of installation. Adhesives on film thicknesses of
0.25 mm 0.010 inch and greater shall be a minimum of 0.02 mm 0.0008 inch
thick. The following tests to indicate compliance with specified
requirements shall be performed by an independent testing laboratory, and
the laboratory reports shall be signed by a responsible official of the
laboratory.
SECTION 08 87 23.13

2.2.1
Impact Performance
**************************************************************************
NOTE: Retain sentences about splices when the film
will be applied to sheets of glass with a dimension
exceeding 1475 mm 58 inches in both directions.
Paragraph 5.1.3 (2) of ANSI Z97.1 and paragraph
1204.4 (e) (1) (ii) of 16 CFR 1201 will not be an
accepted form of testing glazing failure after the
impact test because these paragraphs allow complete
disintegration if fragment particles are small
enough. Complete disintegration of the glazing is
unacceptable under blast loading because the
particles would be propelled into the building and
could seriously injure or kill the occupants.
Designers specifying fragment retention film for use
in other countries may substitute impact test
reports in accordance with British Standard (BS) BS
6206 Class B and German Standard DIN 5237, which use
similar testing methods to the impact tests
specified. The designer should accept but not
specify films tested and receiving an A1 impact
resistance under DIN 52290 or film which has tested
positively in accordance with BS 5544. Do not
specify the film to be tested in accordance with DIN
52290 or BS 5544 because relatively few films can
pass these more stringent impact tests.
**************************************************************************
Fragment retention film shall be tested for impact in accordance with
ANSI Z97.1 or 16 CFR 1201. Tests shall be conducted on fragment retention
film applied to 3.1 to 6.4 mm 1/8 to 1/4 inch-thick annealed flat glass
which conforms to the requirements of ASTM C1036, Type I, Class 1, Quality
q3. The film tested shall be applied to the glass with a splice located at
the midpoint of the specimen. Sketches showing location and configuration
of splice shall be included in submitted certified test reports. After the
impact portion of the test is conducted, satisfactory performance of the
test specimens shall be determined using ANSI Z97.1, paragraph 5.1.3 or
16 CFR 1201, paragraph 1201.4 (e)--INTERPRETATION OF RESULTS. To be
qualified for use under this specification, the manufacturer shall provide
a report that the fragment retention film satisfactorily performed in
accordance with ANSI Z97.1, paragraph 5.1.3 (1), (3), or (4) or with
16 CFR 1201, paragraph 1204.4 (e) (1) (i), (iv), or (v). ANSI Z97.1,
paragraph 5.1.3 (2) or 16 CFR 1201, paragraph 1204.4 (e) (1) (ii) shall not
constitute passing criteria.
2.2.2
Tensile Strength
The fragment retention film samples tested shall exhibit a minimum tensile
strength at break of 172.4 MPa 25,000 psi when tested in accordance with
ASTM D882. Method A, Static Weighing, Constant Rate of Grip Separation
Test, shall be used to conduct this test. The rate of grip separation
shall not exceed 0.2 mm/s 1/2 inch per minute.
2.2.3
Peel Strength
Testing shall be conducted following 1,200 hours accelerated weathering
SECTION 08 87 23.13
Page 8
exposure. The fragment retention film shall exhibit a minimum peel
strength of 930 N/m 5.3 pounds/inch for 0.10 mm 0.004 inch thick film and
790 N/m 4.5 pounds/inch for 0.18 mm 0.007 inch thick and thicker film when
tested in accordance with ASTM D3330/D3330M. Method A shall be used to
conduct the tests. A glass substrate shall be used and a maximum dwell
time of 45 days is permitted.
2.2.4
Surface Abrasion
The fragment retention film shall exhibit a change in haze not to exceed
3.2 percent following 100 turns, using 500-gram weights on a CS 10F
abrasive wheel when tested in accordance with ASTM D1044.
2.2.5
Flame Spread and Smoke Density
**************************************************************************
Note: The designer may delete the requirement for
flame spread and smoke density index if not required
by the project.
**************************************************************************
The fragment retention film shall exhibit a flame spread index not
exceeding 25 and a smoke density index not exceeding 100 when tested in
accordance with ASTM E84. For the test, the specimen shall be mounted to
6.4 mm 1/4 inch thick tempered glass which conforms to the requirements of
ASTM C1048, Kind FT, Type I, Class 1, Quality q3.
PART 3
3.1
EXECUTION
SURFACE PREPARATION
Clean the glass surface, to which the fragment retention film is to be
applied, of paint, foreign compounds, smears, and spatters. After the
initial cleaning, further clean the surface to receive the film in
accordance with the film manufacturer's instructions.
3.2
APPLICATION
**************************************************************************
NOTE: Greater protection for occupants from flying
glass caused by blast loads is achieved by applying
film such that it extends edge to edge of the sheet
and into the bite of the frame. Some gaskets and
compounds can dissolve the film surface, the
adhesive, or the metallic coating interlayer of
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.
**************************************************************************
Provide fragment retention film on window and door glass where indicated.
After surface preparation, apply the fragment retention film in accordance
with the manufacturer's recommendations and instructions. Film shall be
SECTION 08 87 23.13
Page 9
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,
maintain room conditions 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 08 81 00 GLAZING, indicating that
fragment retention film application is a requirement.
**************************************************************************
Apply fragment retention film 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 08 81 00 GLAZING.
Ensure compatibility when contact between the glazing compounds and/or
gaskets and the film occurs. Coordinate fragment retention film
application and curing 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 are not reusable. Compounds include wet
applied or semi-soft compounds such as sealant,
putty, butyl, hypalon, silicone, acrylic,
polyurethane, polysulfide, and preformed semi-solid
tapes. Although existing gaskets are readily
identifiable, determining the composition of
existing compounds to check compatibility with the
film is more difficult and could add expense to the
project.
**************************************************************************
Remove the existing glazing compound, gaskets, and/or stops as required to
expose the existing glass pane. If necessary, remove the glass so that the
film can be applied extending edge to edge of the glass sheet. Install
existing gaskets and/or stops and replace any removed glazing compounds
with new glazing compounds. Removed glazing compounds shall be scrapped
SECTION 08 87 23.13
Page 10
and not reused. Glazing compounds shall be in accordance with
GANA Sealant Manual. Glazing methods shall be in accordance with
GANA Glazing Manual. Ensure compatibility when contact between the glazing
compounds and/or gaskets and the film occurs. Any damaged or broken
glazing and gaskets shall be replaced and reinstalled in kind.
3.2.3
Application to Existing Glass Without Dismantlement
**************************************************************************
NOTE: Retain this paragraph for application where
dismantlement is not possible or is too expensive.
When exposed to the effects of explosives, films
that stop close to the frame but do not extend into
the bite tend to break along the weak edge and
disengage completely from the frame. Because the
disengaged film reinforced glass is held together as
a unit, protection is provided for building
occupants. This application is simplest and the
least costly. Also, coordination and compatibility
of the film with the compounds and gaskets is not
necessary because they do not contact. If the edges
of the existing glazing compounds are particularly
irregular, the designer may specify the film
application to be within a maximum of 5 mm 3/16 inch,
although the 3 mm 1/8 inch maximum is recommended.
**************************************************************************
Fragment retention film shall be applied so that it extends to within 1.6 mm
1/16 inch, with a maximum of [3] [5] mm [1/8] [3/16] inch, of the edge of
the visible glass area.
3.2.4
Application to Existing Glass and Frame Without Dismantlement
**************************************************************************
NOTE: Retain this paragraph for application where
dismantlement is not possible or is too expensive.
Although this application has not been tested under
blast loads, several manufacturers recommend it. In
this application, the film is likely to contact the
existing gaskets and compounds. Trim or a batten
may be indicated on the drawings and/or added to
this paragraph to hide the film edge.
**************************************************************************
Apply fragment retention film past the edge of the visible glass and extend
onto the frame. Amount of film overlap, edge connection to the frame, and
adhesive for adhering film to frame shall be as recommended by the film
manufacturer. Ensure compatibility when contact between the glazing
compounds and/or gaskets and the film occurs.
3.2.5
Splicing
**************************************************************************
NOTE: Overlaps of 0.25 mm 0.010 inch thick and
thicker film are highly visible and are not
recommended. If no glazing has a dimension exceeding
1475 mm 58 inches in both directions, specify that
the film may not be spliced.
**************************************************************************
SECTION 08 87 23.13
Page 11
[Splices or seams in fragment retention film are not permitted.] [Splices
or seams in fragment retention film are permitted only when a sheet of
glass has a dimension exceeding 1.475 m 58 inches in both directions. All
seams shall be applied with a minimum overlap of 6 mm 1/4 inch unless
submitted test reports indicate impact performance is not diminished when
seam is applied with a different overlap or a gap.]
3.3
CLEANING
Clean the fragment retention film in accordance with the manufacturer's
instructions.
