DefenseLite security shield protects your school, storefront, or office from:

  • Forced entry

How Is DefenseLite Installed?

DefenseLite is installed over your existing window or door opening, mounted either on the exterior or interior of the glass. When anchored to the existing window frame, an airspace is created between the primary glass and the DefenseLite clear shield.

Weather sealed and engineered to be removable when needed, DefenseLite is custom made for every window or door and designed to blend into the existing framing. Once installed, it’s nearly invisible.

Other Window Protection Products From Elite Security Glazing

At Elite Security Glazing, we rate our window protection products as good, better, and best. DefenseLite is our “better” solution because it’s a step above security window film, but while it has proven to stop small-caliber rounds, it’s not as bulletproof as BulletShield.

Good: 3M™ Safety & Security Window Films

3M™ Safety & Security Window Films are applied directly to your existing glass and designed to delay entry through windows and doors. Properly installed, security window film can delay entry for 15-45 seconds, making it an excellent deterrent for smash-and-grab crime.

Best: BulletShield

For the most advanced window protection, we can create a bulletproof barrier with BulletShield, the bullet-resistant version of DefenseLite with UL 752 ballistic ratings.

When you’re searching for a retrofit security glazing solution to protect against forced entry, it’s best to compare your options side by side. Experiencing the differences in performance is the only way you’ll know you’re getting exactly what you’re looking for, which is why we always offer free consultations!
