Ballistic Glass for Banks: What Level of Protection Is Needed?

Written by Adam Baird | Apr 16, 2026 2:49:04 PM

If you’re looking at ballistic glass for a bank, the real question isn’t whether you need it. It’s how much protection actually makes sense for your layout. Go too light, and you leave gaps. Go too heavy, and you’re spending more than you need to.

Most of the time, the answer comes down to where the glass is going and what that area is exposed to.

Why Banks Use Ballistic Glass

There’s a reason you almost always see some form of protective glass at a bank. The goal is to protect people in moments where there’s very little margin for error. Banks require close interaction with the public, often involving cash or sensitive exchanges. That combination creates exposure.

Ballistic glass is used to reduce that exposure without shutting down the interaction itself. Employees can still see clearly, communicate easily, and do their jobs. The difference is there’s a barrier in place if something goes wrong.

There’s also a deterrent factor. When protective systems are visible and integrated into key areas, they signal that the facility is hardened. That alone can influence behavior before anything escalates.

What Level of Ballistic Glass Do Banks Actually Use?

The answer depends on the application. Because not every area of a bank carries the same level of risk, bulletproof glass is manufactured in different protection levels based on what it’s designed to stop:

  • Levels 1–3: Designed for common handgun threats
  • Levels 4–6: Covers higher-caliber handguns and some rifle scenarios
  • Levels 7–10: Built for rifle threats and higher-risk environments

These levels fall under UL 752 standards. If you want the full breakdown of what each level stops, check out our ballistic glass ratings guide.

For now, the better question is where each level actually makes sense inside a bank. Some areas are controlled. Others are exposed. That difference drives the level of protection.

Teller Windows and Transaction Counters

This is the most common use case. You’ve got regular interaction, but it’s still a managed environment.

Most banks land somewhere in the middle here around UL 752 Levels 3-5. Enough protection to stop typical handgun threats, without making the glass overly thick or difficult to work through.

Drive-Thru and Exterior Transaction Windows

Different story here. Anything facing the outside carries more unknowns. You don’t have the same level of control over distance or access, which is why protection levels often increase to Levels 5–8.

You’ll usually see stronger setups paired with transaction drawers or pass-through systems to limit exposure even further.

Entry Areas and Public Lobbies

This one depends a lot on the design. Some banks will use ballistic glass at entry points, especially in the form of glass doors or front-facing window systems. When they do, it’s often in the Level 1–3 range.

Not every bank goes this route though. A lot of layouts keep the lobby more open and focus protection on the areas where interaction actually happens, like teller lines or controlled access points.

If the location carries more risk, you might see higher levels used at the entrance or tied into access-controlled areas. But in most cases, it’s not about hardening the entire lobby. It’s about reinforcing the spots that matter.

Security Offices and Back-End Areas

These areas don’t get talked about as much, but they still factor in. If a space is tied to monitoring, cash handling, or restricted access, higher protection levels can come into play. Especially in facilities with a higher overall risk profile.

These spaces can vary quite a bit, but when protection is used, it’s often Levels 5–8 or higher.

What Determines the Right Protection Level for Banks?

There’s always a reason behind the level that gets chosen.

A few things tend to drive that decision:

  • Where the bank is located and the type of risk it carries
  • Whether the glass is inside or exposed to the exterior
  • How people interact at that position
  • How much visibility is needed without sacrificing protection
  • Whether you’re retrofitting or starting from scratch

None of these exist in a vacuum. They stack on top of each other, and that’s what ultimately points you toward the right level.

Choosing the Right Ballistic Glass for Your Bank

The easiest way to approach it is to think in zones. Where are people exposed? Where is interaction happening? Where would added protection actually make a difference?

Once those areas are clear, matching them to the right level becomes a lot more straightforward.

That’s usually where working with someone who’s seen real installations helps. Not just specs on paper, but how it all comes together in an actual bank environment.
