A few things drive the cost of bulletproof glass: the ballistic rating, what it’s made of, and the size. On average, expect to pay $40 to $100 per square foot for the material on basic protection, though high-end, multi-layered options can run past $200 per square foot.
Worth clearing up first: “bulletproof glass” isn’t really the right term. The industry calls it bullet-resistant glass, and it’s usually made from layers of laminated glass combined with polycarbonate or acrylic. A UL Level 1 rating, which stops 9mm handguns, is the most affordable option out there. Move up to Level 3, the standard for most commercial security, or Level 7 and 8, used for military and high-threat government applications, and the glass gets thicker and heavier fast. That’s what pushes the price up.
Custom shapes, tints, and one-way viewing capability all add to the total as well, and you’ll want to budget for the specialized shipping and handling this kind of heavy, sensitive material requires. Since the glass only works as well as its installation and how well the rating matches the actual threat, it’s worth talking to a security professional for a real quote rather than guessing at what you need.
