When it comes to facility security, the terms “bulletproof” and bullet-resistant doors are often used interchangeably. But in reality, there’s an important distinction, and understanding it can make all the difference when protecting your school, hospital, or government building.
In this blog, we’ll break down what bullet-resistant doors are, why “bulletproof” is a misleading term, and how the right terminology connects directly to real-world performance and expectations.
What Are Bullet-Resistant Doors?
Bullet-resistant doors are designed to resist penetration from firearms and to maintain structural integrity under ballistic impact. These doors are built with UL 752-rated cores and glazing options, meaning they meet rigorous performance standards set by third-party testing agencies.
At Iron Badger Defense Solutions, our bullet-resistant doors are custom-built to fit existing frames and can be finished in solid wood, veneer, or laminate, delivering both protection and professional aesthetics.

Why “Bulletproof” Is a Misleading Term
The word “bulletproof” implies complete and indefinite immunity to bullets, something that no material or product can truly guarantee. Under extreme conditions, even the strongest materials can be compromised.
Industry professionals instead use the term “bullet-resistant”, which more accurately reflects a door’s tested ability to stop specific types of firearms at defined velocities and distances.
The U.S. Department of Justice and the National Institute of Justice (NIJ) classify ballistic materials based on their resistance levels. To see how those standards are established, visit the official NIJ ballistic resistance guide.
UL 752 Ratings: What Do They Mean?
UL 752 is the standard that certifies materials for ballistic resistance. Bullet-resistant doors are typically rated from Level 1 to Level 8:
- Level 1: 9mm handgun
- Level 3: .44 Magnum
- Level 8: 7.62mm rifle rounds
At Iron Badger, we offer custom door systems rated to your facility’s specific threat profile. Whether you need Level 1 protection for a school vestibule or Level 8 for a government entry point, we fabricate and install to exact standards.
School Security & Missouri Senate Bill 68
In 2025, Missouri passed Senate Bill 68, a state-wide mandate requiring public schools to enhance their physical security, starting with stronger entry point protections. This includes the installation of anti-intruder door locks on all exterior doors by July 2029.
While anti-intruder locks are a key part of that law, they work best when paired with ballistic-rated entry doors. Bullet-resistant doors help slow or stop intrusions, while secure locking devices delay unauthorized access and give first responders more time to act.
Together, these solutions help schools comply with legal requirements and strengthen real-world protection for students and staff.

Use Cases: Where Bullet-Resistant Doors Matter Most
Schools
Protecting students and staff from active shooter threats starts with securing entry points. Bullet-resistant narrow vision doors help slow intruders and buy time for emergency response.
Hospitals
High-traffic public entrances and sensitive care units benefit from added protection, without sacrificing design or compliance with access control systems.
Government Buildings
Courthouses, police departments, and administrative offices rely on ballistic-rated doors to prevent breaches and protect personnel.
Retail & Private Sector
Facilities at risk of armed robbery or forced entry, such as banks or high-end retail, use bullet-resistant doors to reinforce vulnerable locations.
