Overview
Blast-resistant window film
was credited for saving many
lives during the September 2001
terrorist attack on the Pentagon.
In the event of a nearby explosion,
a building's Achilles heel is
typically its glazed surfaces.
Shattered into razor sharp fragments
and propelled at high speeds,
window and door glass can cause
severe injury to a building's
occupants. In addition, shattered
glazing allows blast over-pressure
to enter the building. This,
too, poses a serious threat
to the safety of those inside
and outside.
Extensive testing has proven
that the threat of injury due
to flying glass can be greatly
reduced by the use of 3M
Scotchshield™ Ultra Safety
& Security window films.
These tough, transparent, blast-resistant
films consist of multiple, microthin
polyester layers that work to
hold shattered glazing together.
Consequently, there are fewer
fragments and debris capable
of inflicting harm.
3M
Scotchshield™ Ultra Safety
& Security films greatly
enhance the protective capability
of glass in a very unobtrusive
manner. These thin, pliable
films can be applied quickly
and easily over existing windows.
Over the course of many years,
they maintain a high level of
optical clarity, even during
extreme conditions. Unlike thick,
single-layered films that tend
to be stiff and boardy, 3M
Scotchshield™ Ultra Safety
& Security films use microthin,
cross-woven layers that are
laminated together to enhance
tensile strength and elongation.
This patented film construction
delivers superior performance
over standard polyester in blast
and impact mitigation due to
its ability to absorb shock.

is no substitute for technology.)
Additional blast protection
is offered through the use of
an attachment system. An attachment
system helps to prevent the
entire glass pane from being
blown out of the window frame.
3M's Ultraflex
attachment system is a structural
silicone that bonds the film
to the glass to the frame. (Click

systems.)
Scotchshield™ films were
tested by an independent agency
and achieved a Very High protection
level and a Condition 2 on the
GSA rating scale when tested
with a standoff distance of
121 feet and a peak pressure
of 9 psi. (Click here to learn
more about blast protection
standards and testing results.)
Scotchshield's™ tough,
transparent, multiple, microthin
polyester layers work to hold
shattered glass in place. Consequently,
potential burglars are deterred
from attempting access through
a window that is difficult to
break. Clear Scotchshield™
films are the perfect solution
to a retailer or homeowner seeking
protection without sacrificing
visibility.
Scotchshield™ films are
maintenance-free, vary in thickness
(from 1.5 mils to 14 mils*),
and provide some of the energy
benefits associated with Scotchtint™.
