Glazed Surfaces: Your Property’s Weakest Link
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, and even death, 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.
Fragment retention window film was credited for saving many lives during the September 2001 terrorist attack on the Pentagon.
A New Generation of Blast Film
3M has been manufacturing tough, tear-resistant window films to mitigate the effects of a bomb blast since the late 1960s. However, in 2024, 3M introduced its Scotchshield Safety & Security Window Film System S2400, a urethane-based security film that is more flexible than typical polyester-based (PET) films. This additional flexibility helps to provide greater Elongation at Break (560%) as compared to other films on the market, providing greater tear resistance in certain applications and situations. S2400 has been tested to the following standards:
- ANSI Z97.1
- 16 CFR 1201
- ASTM F1233
- ASTM E1886 & E1996
3M Safety & Security Window Films, such as S2400, are not tested to ASTM F3561-22. Learn More.

Independent GSA Testing
3M Safety & Security Window Films have been tested by independent agencies to the security criteria established by the GSA.

GSA Protection Standard
Performance Criteria | Protection Level | Hazard Level | Description of Window Glazing Response |
|---|---|---|---|
1 | Safe | None | Glazing does not break. No visible damage to glazing or frame. |
2 | Very High | None | Glazing cracks but is retained by the frame. Dusting or very small fragments near sill or on floor acceptable. |
3a | High | Very Low | Glazing cracks. Fragments enter space and land on floor no further than 3.3 ft. from the window. |
3b | High | Low | Glazing cracks. Fragments enter space and land on floor no further than 10 ft. from the window. |
4 | Medium | Medium | Glazing cracks. Fragments enter space and land on floor and impact a vertical witness panel at a distance of no more than 10 ft. from the window at a height no greater than 2 ft. above the floor. |
5 | Low | High | Glazing cracks and window system fails catastrophically. Fragments enter space impacting a vertical witness panel at a distance of no more than 10 ft. from the window at a height greater than 2 ft. above the floor. |
3M’s fragment retention films are maintenance-free, vary in thickness (from 4 mils to 24 mils*), and provide some of the energy benefits associated with 3M sun control films.
