SL-15 | SL-31 | BR
SECURITY GLASS LAMINATES FOR BLAST, BULLET, & FORCED ENTRY PROTECTION

Clear Armor's security window laminate is organized by threat level: SL-15 for forced-entry protection, SL-31 for riot-resistant protection against sustained attacks or multiple attackers, and BR for bullet-resistant applications.

CLEAR ARMOR 15-MIL SECURITY LAMINATE

SL-15 LAMINATE

SL-15 is typically recommended for schools, small businesses, and homes that need practical forced-entry resistance without full glass replacement. 

Forced-Entry Protection

SL-15 helps existing panes function more like burglar-resistant glass by holding damaged glass together after impact. The 15-mil laminate helps slow break-ins, smash-and-grabs, and forced-entry attempts, buying occupants and first responders more time to act.

Fortifies Existing Glass

SL-15 is optically clear, strengthening vulnerable glass while preserving visibility and appearance. The 15-mil laminate is tested to the ANSI Z97.1 impact standard for safety glazing.

15-MIL Protection

SL-15 uses a 15-mil laminate with a 420-psi breaking strength to reinforce glass doors, windows, sidelites, and other vulnerable access points without full replacement.

CLEAR ARMOR 31-MIL SECURITY LAMINATE

SL-31 RIOT LAMINATE​

SL-31 Laminate is the riot-resistant security laminate built for prolonged crowd events, civil unrest, and sustained, targeted attacks. 

31-MIL Protection

SL-31 is a 31-mil security laminate that helps keep damaged glass in place under repeated impact. Buyers may call this “riot-proof glass,” but the more accurate term is riot-resistant laminate, which helps delay a breach and supports response protocols. The 31-mil laminate is tested to the ANSI Z97.1 impact standard for safety glazing.

Higher-Threat Protection

SL-31 includes the forced-entry protection of SL-15, then adds greater resistance for more severe scenarios. With a 31-mil thickness and a 1,100-psi breaking strength, SL-31 is built for prolonged threats where standard glass or lighter-gauge film may not provide sufficient delay.

Delays Attacks

SL-31 Riot Laminate helps hold glass in place during an attack, giving occupants more time to call first responders, move to safer areas, or follow active-threat protocols. For facilities comparing security film, window security laminate, and riot-resistant laminate, SL-31 is built for sustained impact resistance.

CLEAR ARMOR BR LAMINATE

BULLET RESISTANT LAMINATE

BR Laminate is a top-tier protective glass-laminate configuration tested for bullet-resistant performance under specified conditions.

Optically Clear Security

BR Laminate strengthens high-risk glass doors and windows while maintaining clear visibility. For banks, government facilities, critical access points, and sensitive entrances, that balance of visibility and protection helps support a broader facility security plan.

One-Way Protection

BR Laminate supports one-way protection, helping protect people inside while allowing a defensive response outward when the system is installed for that purpose. Although many buyers search for “bulletproof glass,” the more accurate term is “bullet-resistant laminate” because no product should be described as universally bulletproof against all threats.

Bullet-Resistant Protection

BR Laminate is built for facilities that need bullet-resistant protection from common handgun rounds. In independent testing, Clear Armor's ballistic laminate met NIJ Standard 0108.01 Type II-A against 9mm on 1/4-inch glass (Intertek) and showed no penetration under UL 752 Level 3 conditions against .44 Magnum on 1/2-inch glass (Element U.S. Space & Defense). The applicable rating depends on the glass type, laminate configuration, and application requirements.

Frequently Asked Questions

What is security window laminate?

Security window laminate is a protective film applied to existing glass to help hold the pane together after impact. It strengthens vulnerable glass without requiring full glass replacement.


What is the difference between SL-15, SL-31, and BR laminate?

SL-15 is the entry-level forced-entry tier, SL-31 is the higher-threat riot-resistant tier, and BR is the bullet-resistant tier.


What is a riot-resistant security laminate?

A riot-resistant security laminate is a multi-layer film applied to existing glass to help it resist repeated impact during crowd events, civil unrest, or sustained attacks. Clear Armor’s SL-31 Riot Laminate is a retrofit security window laminate built for these higher-threat scenarios.


Is bullet-resistant glass the same as bulletproof glass?

Bullet-resistant glass is the more accurate term because ballistic protection depends on the product configuration, test rating, ammunition type, and installation conditions. Many people use “bulletproof glass” casually, but no glass or laminate should be considered universally protective against all ballistic threats.


Does security window laminate go on existing windows?

Security window laminate is applied to existing windows, doors, sidelites, and other glass surfaces. That retrofit approach helps facilities strengthen vulnerable glass without replacing the full glazing system.


What can the BR laminate stop?

BR Laminate is built for bullet-resistant applications involving common handgun rounds and 00 buckshot, depending on configuration. The applicable rating depends on the specific BR assembly, glass type, and installation requirements.

Review the Right Security Window Laminate for Your Facility

Security window laminate helps transform existing glass into a stronger protective barrier for forced-entry, riot, blast-related, and ballistic threat planning. The right tier depends on your facility type, glass conditions, threat profile, and documentation needs.
