It’s Not Just About Looks—It’s About Long-Term Safety

When it comes to upfitting your fleet for law enforcement or public safety use, every piece of equipment matters. But one element that often gets overlooked? The window screens. Whether you’re retrofitting patrol vehicles or customizing new ones, choosing between steel or polycarbonate window armor isn’t just about aesthetics—it’s a decision that impacts safety, visibility, durability, and performance.

So, how do you know which material makes the most sense for your agency’s needs? Let’s break down the pros, cons, and common use cases of each—so you can feel confident your team has the protection it needs without sacrificing function.

Steel Window Screens: Built Like a Tank

If you’re prioritizing toughness above all else, steel window screens are your go-to. These are heavy-duty, welded mesh barriers that are nearly impossible to break through. Steel is particularly favored in high-risk transport vehicles or correctional fleets where restraint and security are paramount.

Here’s why departments lean toward steel:

• Maximum impact resistance—great for high-risk prisoner transport

• Difficult to tamper with or break

• Long-lasting in extreme weather conditions

• Ideal for rear windows where visibility isn’t as critical

But there are a few trade-offs. Steel is heavier than polycarbonate, which could slightly impact fuel efficiency or vehicle performance over time. Plus, it may reduce visibility, depending on the mesh pattern and placement.

Polycarbonate Window Screens: Lightweight, Strong, and Clear

Don’t let the lighter weight fool you—polycarbonate screens are no slouch when it comes to strength. In fact, poly is known for its high impact resistance, and it offers the bonus of crystal-clear visibility, making it a solid option for agencies who want both safety and situational awareness.

Why polycarbonate is gaining popularity:

• High optical clarity—officers can still see out the window

• Lighter weight, reducing strain on vehicle performance

• Easy to install and often looks more integrated with factory design

• Resistant to cracking or shattering under pressure

The biggest drawback? It can scratch more easily than steel and may need occasional replacement in high-use environments. But for most patrol units, especially those used in community policing or city environments, polycarbonate offers the best of both worlds.

Which One Is Right for You?

Ultimately, the decision comes down to how your fleet is used. For correctional transport or high-risk environments, steel may be worth the extra bulk. But if visibility, speed, and ease of use matter more, polycarbonate is the smart play.

You should also consider compatibility with other vehicle safety upgrades—like prisoner seating, belt systems, or door armor. A well-integrated build not only keeps your officers and detainees safer, but it also helps your fleet last longer and stay in top working condition.
