When a security consultant asks for bullet resistant polycarbonate sheet, the first thing I want to know is not the price but the threat. A panel built to stop a 9 mm handgun and a panel built to stop a rifle are different products, and buying the wrong one is worse than buying none because it gives false confidence. UL 752 levels exist to make that threat clear.
How UL 752 levels map to your risk
UL 752 defines ballistic levels from level 1, which stops common handgun rounds, up to level 8 for rifle threats. The panel thickness and lamination grow with the level: a level 3 panel that stops a .44 Magnum needs a heavier build than a level 1 panel. Matching the level to the actual threat at your site is the whole job of the specifier.
Why polycarbonate, and why it must be laminated
Polycarbonate absorbs impact without the spalling that shatters glass, and it is far lighter than glass of equal protection, so the frame and structure carry less load. For higher threats the sheet is laminated — bonded in multiple plies — so each layer slows and stops the round. A single thick sheet is not a substitute for a designed multi-ply panel.
For the level-by-level breakdown, our guide to UL 752 ballistic ratings explained is the companion read, and the composite build is covered in laminated polycarbonate glazing.
Frequently Asked Questions
Q: What thickness is bullet resistant polycarbonate sheet?
A: Thickness rises with the threat level; typical laminated panels run from about 25 mm up to 50 mm and more depending on the UL 752 level you need.
Q: Does a bullet resistant polycarbonate panel stay clear?
A: Yes, properly laminated polycarbonate keeps good optical clarity while stopping the round, which is why it is used for bank counters and security glazing that must keep daylight.
