How bulletproof glass works

Bulletproof glass is not just thicker glass: it is a laminate of several glass layers bonded with layers of clear plastic, such as polycarbonate. Each layer has a different job.

What happens when a shot arrives

The outer layer, hard glass, deforms and breaks the projectile. The inner, more flexible layers absorb the remaining energy and keep fragments from reaching the cabin. The glass cracks around the impact, but the projectile stays trapped in the laminate. The illustration is a diagram: it does not show real thicknesses.

Why it is thick

The higher the protection level, the more layers and thickness. At RGM Armor, glass ranges from 32 to 42 mm depending on the level, with good visibility (see bulletproof glass). More thickness also means more weight in each door.

One side matters

Many bulletproof glass panels have a face meant to point outward. Installing them backwards reduces protection, which is why trained personnel do the installation.

Everyday care

Wash the glass with water, mild soap and a clean cloth. Avoid metal scrapers, abrasive cleaners and knocks on the edges. If you see bubbles, milky spots or layers separating at the edge, ask for an inspection: it may be delamination.

After an impact

Glass that took a shot should be inspected and, normally, replaced even if it looks intact. Cracks can reduce its ability to take a second hit in the same area.
