What Is 3M™ Scotchshield™ Ultra S800 Security Window Film?

In an uncertain world, protecting people and property is more important than ever. From schools and hospitals to hotels, offices, and government buildings, glass windows are one of the most vulnerable entry points in any structure.

That’s where 3M™ Scotchshield™ Ultra S800 comes in—a high-performance, tear-resistant safety and security window film designed to help protect against forced entry, flying glass shards, and even explosions.

Let’s dive into what makes Ultra S800 one of the most trusted names in passive glass protection.

What Is 3M™ Ultra S800?

3M™ Scotchshield™ Ultra S800 is an 8-mil (0.20mm) thick, micro-layered polyester security film applied directly to glass windows and doors. It's designed to hold shattered glass together, helping prevent dangerous shards from becoming airborne hazards during break-ins, blasts, or natural disasters.

Its advanced construction helps delay intruders, deter attacks, and reduce the risk of injury in critical moments—all while being optically clear and virtually invisible once installed.

How It Works: Micro-Layered Strength and Tear Resistance

Unlike traditional window films, Ultra S800 is built using a co-extruded, multi-layered construction. This micro-layered design enhances its tensile strength and tear resistance, making it incredibly difficult to penetrate or rip apart—even under duress.

Independent Lab Test Results:

• Tensile Strength: 31,500 psi

• Break Strength: 253 lbs/in

• Thickness: 8 mils (0.20 mm)

These numbers place Ultra S800 among the strongest window films in the industry, making it a top choice for both commercial and institutional security upgrades.

What Does Ultra S800 Protect Against?

Security film isn’t just about theft prevention. It serves multiple functions by reinforcing one of the weakest points in a building—its glass.

🛡️ Protection Against Forced Entry

Glass is often the easiest way for intruders to gain access. Ultra S800 helps delay entry, giving law enforcement or on-site security more time to respond.

When paired with 3M™ Impact Protection Attachment Systems, which anchor the film to the window frame, this solution becomes even more effective at resisting high-force entry attempts, including those using crowbars, hammers, or firearms.

💥 Blast Mitigation

In the event of an explosion—accidental or intentional—flying glass shards are a major cause of injury or death. Ultra S800’s design holds broken glass in place, helping to reduce injuries by keeping shards from becoming deadly projectiles.

This is why Ultra S800 is often used in:

• Government buildings

• Embassies

• Airports

• Military facilities

• Sensitive infrastructure

Where Is Ultra S800 Typically Installed?

Anywhere that safety and security are a concern, Ultra S800 is a viable solution. It’s especially valuable in:

• 🏫 Schools and universities – Improve safety without changing appearance

• 🏨 Hotels and resorts – Invisible protection for guest-facing windows

• 🏥 Hospitals and healthcare facilities – Maintain open, sunlit spaces while protecting patients and staff

• 🏢 Corporate offices – Deter smash-and-grab theft

• 🏛️ Government and municipal buildings – Reinforce critical infrastructure

• 🛍️ Retail storefronts – Reduce theft and protect employees

Because it’s optically clear, the film doesn’t affect aesthetics or visibility—making it ideal for public-facing glass where design matters.

The UV Protection Bonus

Like all 3M™ window films, Ultra S800 rejects 99% of harmful UV rays. This protects:

• Art and signage from fading

• Interior furnishings and floors from UV damage

• People inside from prolonged UV exposure

So in addition to safety, it also provides valuable fade protection and occupant health benefits—without any noticeable darkening or tint.

Why Choose Ultra S800 Over Other Security Measures?

You might be wondering: Why not just install laminated glass or bulletproof windows?

While those solutions have their place, they’re often cost-prohibitive, require structural upgrades, and may change the look of the building. Ultra S800 is cost-effective, non-intrusive, and far more flexible.

Solution	Cost	Installation Disruption	Appearance
Bulletproof Glass	$$$$	High	Obvious
Laminated Security Glass	$$$	Medium	Visible layers
3M Ultra S800	$	Low	Invisible

Especially when combined with a 3M™ Impact Protection Attachment System, Ultra S800 creates a passive defense barrier that’s hard to beat in terms of performance-to-price ratio.

Professional Installation Matters

To be effective, Ultra S800 must be installed by a 3M-certified installer. Precision cutting, edge sealing, and correct bonding to glass are all critical components to ensure the film performs under real-world stress.
