RiotLite™ Security Film | FSJ Tactical
RiotLite Security Film, Retrofit Riot Glass Protection for Existing Windows
A multi-layer, optically clear security film independently tested to ASTM F3561 Level 3. RiotLite strengthens storefronts, windows, and doors against riots, looting, and smash-and-grab.
When violence strikes, glass windows and doors are the first targets for forced entry, vandalism, and theft. RiotLite™ is the cost-effective first layer of protection: an advanced multi-layer security film applied directly to existing glass that keeps it in place and slows attackers down.
Delay and Prevent
RiotLite provides enhanced forced-entry resistance and has been independently tested to ASTM F3561 Level 3. It strengthens storefronts, windows, and doors, mitigating risks from riots, looting, and smash-and-grab incidents. With a nearly invisible profile, RiotLite preserves natural light and aesthetics while offering discreet yet powerful protection for schools, retail storefronts, and other at-risk glass.
How RiotLite Works
RiotLite is an optically clear film "stack" built from multiple PET security film layers in a proprietary arrangement. When glass is struck by fists, rocks, crowbars, or bats, the film absorbs and spreads the impact and holds the broken glass together. Paired with mechanical attachment to the frame, the glass stays anchored in the opening instead of falling or being pushed out.
Benefits
Retrofit to Existing Glass
No window replacement. RiotLite is applied directly to the interior glass you already have.
Stackable Protection
Layered construction up to 41 mil lets FSJ Tactical tune protection to the threat.
Shatter Resistance
Holds glass fragments together to reduce injuries from broken glass caused by impact, storms, or blasts.
Strong, Shock-Absorbing Adhesion
An aggressive adhesive system bonds tightly to glass and absorbs shock.
Scratch-Resistant Hard Coat
A protective hard coat keeps the surface durable and clear.
UV Protection
Strong UV inhibitors reduce fading of interior furnishings and merchandise.

Where RiotLite Fits
RiotLite is a Security Level I solution in the DefenseLite system: delayed entry and slowed smash-and-grab. It's ideal for:
- Retail storefronts, hospitals and clinics, hotels, commercial offices, and data centers
- Government buildings, courthouses, and police stations
- Dispensaries, gun shops, and pawn shops
- Schools and campuses, banks, and houses of worship
- Residential glass
In a Zones of Defense plan, RiotLite is typically used on Zone 3 interior glass and lower-risk Zone 2 windows. For primary entries, step up to DefenseLite Pro for ASTM F3561 Level 8 forced-entry resistance or BulletShield for ballistic protection.
Film vs. Polycarbonate: An Honest Comparison
RiotLite is a strong, economical way to slow attackers. But film on glass can still be defeated with enough repeated blows. DefenseLite polycarbonate shields flex and absorb impact without breaking, and they stay intact even when the glass behind them shatters. Read our security film comparison to see which is right for each opening.

Frequently Asked Questions
What is RiotLite?
RiotLite is a stackable, multi-layer security film applied directly to existing glass. It uses optically clear PET film layers, strong UV inhibitors, an aggressive adhesive system, and a scratch-resistant hard coat. RiotLite (RL27) has been independently tested to ASTM F3561 Level 3.
Is RiotLite bullet proof window film?
No. RiotLite is a forced-entry and shatter-resistance film. It does not stop bullets on ordinary glass. For ballistic protection, FSJ Tactical recommends BulletShield.
How thick is RiotLite?
RiotLite is stackable, with protection up to 41 mil. FSJ Tactical typically recommends 36 to 41 mil configurations with mechanical attachment for meaningful forced-entry delay.
Why does mechanical attachment matter?
Without attachment, a filmed pane can be pushed out of the frame as a single sheet. Mechanically attaching the film to the frame keeps the glass anchored, which is how RiotLite is tested as a system.
How do I clean RiotLite?
RiotLite's hard coat resists scratches and can be cleaned with common window-cleaning solutions. Avoid abrasive pads and razor blades.
