3M Safety & Security
Window Film Specification Guide
As a leader in both adhesive and film technologies, 3M brings together these disciplines to create the finest products available for residential, commercial and government buildings.
Our films reduce up to 99% of the sun's ultraviolet rays and reject up to 79% of the solar heat that may otherwise come through a window.
3M Safety and Security Films provide fragment retention by helping to hold glass together during destructive weather, smash and grab crimes and vandalism or even acts of terrorism.
They help to seal out the water, the primary cause of property damage and they have a toughness that allows these films to withstand day-to-day abuse.
Safety & Security Films
3M™ offer a comprehensive range of Safety & Security Film options to cover the widest variety of needs. The range
starts with the conventional PET SH series and extends up to the Ultra Microlayered Security Films. The range also
covers other innovative products such as the CI (Counter Intelligence) films. These have been designed for
protection against electronic signals and eavesdropping.
When it comes to Window Films for physical security, thickness is no substitute for technology. 3M’s Ultra
Microlayered Security Films offer unique technology. In fact, ULTRA600 has 42 layers of alternating materials
in an optically clear film just 0.15mm thick! This 3M patented technology provides superior performance over
conventional PET films.
The best way to demonstrate the superior properties of the Ultra Microlayered Security Films
is to perform a tear test. Inside this folder you will find a set of film samples, each sample
has a slit through one side. Start with the standard PET film sample, grip the film with each
hand either side of the slit and tear the sample, you will find that it tears quite easily. Now
repeat the process with the Ultra Microlayered Security Film. You will find a significant
difference in the tear performance of the products.
The Ultra Microlayered Security Films superior tear resistance is the standout feature of the technology. However,
it is more than just its tear resistance that gives Ultra its superior performance. Security film performance is about
managing and absorbing energy from events such as bomb blasts and flying projectiles (rocks) etc. No individual
security film property can give an indication of its overall performance, below is an explanation of the key material
properties that dictate performance.

 |
| Ultra Microlayered Security Film has a lower Young’s modulus (is less stiff) than conventional films. This means that Ultra Microlayered Security Film begins to stretch and absorb energy more easily than conventional PET films. | Ultra Microlayered Security Film also has a greater elongation to break than conventional films. This means that Ultra Microlayered Security Film can stretch more and absorb energy over a longer period of time than conventional films. | Ultra Microlayered Security Film has a higher Ultimate Tensile Strength (UTS) than conventional films. This means per micron thickness, it is ultimately harder to break than conventional film. |
All of these properties mean that the Ultra Microlayered Security Films is
supremely effective at absorbing and distributing energy, providing
increased safety against physical attack.
The Ultraflex attachment system was developed by 3M to compliment the
properties of the Ultra Microlayered Security Film. The system attaches the
Security Film into the window frame by way of a structural silicone bead. This
flexible attachment system coupled with the Ultra Security Film acts to soften
the impact that is transferred into the window frames during a physical event.

The ULTRA400 series includes SCLARL400, S20SIAR400, S25NVAR400, S35NEAR400, S50NEAR400 and CI100B. This range covers applications that require increased security along with solar control or electromagnetic shielding (CI).
Further Definitions
Graves Area Tear: The measurement of a material to resist both initial tear as well as continued tearing.
When punctured Ultra films will continue to have high strength.
Puncture Propagation Tear: Resistance to Puncture and Tear.
Greater resistance to Puncture and Tear means higher resistance to forced entry, bomb blast, storm cycling.
Abrasion Resistance: Measures the ability of the film’s surface to resist scratching.
The lower the % change in haze, the more durable the film is to maintain appearance after many cleanings.
Blast Tests: The results demonstrated that glass treated with 3M ULTRA400 & ULTRA600 offered significant increased
protection against the dangers of flying glass caused by explosive blast loads.
