DefenseLite · Polycarbonate Security Glazing
DefenseLite is a clear polycarbonate shield mounted over your existing windows, up to 250x stronger than glass, that prevents forced entry instead of just slowing it down.
Why it matters
Security film buys you seconds. For storefronts, schools, and high-risk sites, seconds are not enough. DefenseLite mounts a clear polycarbonate barrier over your existing glass so an intruder cannot break through at all, protecting the people and property behind the window.

Good to know
Security film holds broken glass together and delays entry. DefenseLite is a separate clear polycarbonate panel, up to 250x stronger than glass, mounted over your existing window in a custom frame, so it prevents entry rather than just slowing it.
No. DefenseLite is a retrofit. It mounts over your existing glass, so there is no need to tear out and replace your windows.
DefenseLite is built to defeat forced entry and impact, not gunfire. For ballistic protection we install BulletShield, which is tested to UL 752.
