Article Summary
- There’s no such thing as bulletproof doors — only bullet-resistant ones.
- UL’s bullet resistance ratings indicate the number of shots from specific handguns or rifles that a high-security door can withstand.
- Hidden Door Store offers UL-certified and FE5- or FE15-rated products that meet many ift Rosenheim standards.
Not Sure Which Ballistic Level You Need? Here’s How to Decide
Ballistic resistance is an essential quality of high-security doors. However, not every door that claims to be “bulletproof” can stop bullets from every kind of gun. Understanding bulletproof ratings can help you choose the most suitable door to neutralize the threats you worry about the most. Use this guide from Hidden Door Store to decide on the appropriate ballistic level for your security door.
Start With Your Primary Threat Level
Underwriters Laboratories (UL) 752 is the name of the standard for ballistic protection. Its new designation system specifies whether the door can stop handguns, rifles and/or shotguns. Conventionally, the UL752 standard uses levels to indicate the bullet resistance of materials and assemblies. Generally speaking, the higher the level, the more powerful a gun an armored door can stop.
Select a UL level that aligns with your home security objectives. If you want to prioritize opportunistic crime, a high-security door designed to safeguard against handguns may suffice.
According to the United States Bureau of Alcohol, Tobacco, Firearms and Explosives’ manufacturing and tracing data, pistols have outsold other firearms in most years since 2010 and accounted for the majority of traced guns in the U.S. in 2023. Chances are, armed burglars may carry pistols when they break in.
Targeted threats are different. Armed malicious characters may target you because of who you are or what you do. If you’re a high-net-worth individual, a famous person, a controversial figure, a hated senior executive or somebody who has enemies, consider a ballistic door with a higher rating to protect yourself and your loved ones from murder attempts or targeted burglaries.
What Do Ballistic Ratings Actually Mean
Bulletproof doors are a misnomer. Even steel-reinforced doors eventually fail under relentless attacks. Ballistic ratings indicate bullet resistance, not insusceptibility to damage.
UL 752 aims to determine the type and number of projectiles that specific materials can withstand. Its rating has 10 levels. The table below shows what a door has to withstand in order to qualify for a given rating per the UL 752 standard:
| UL 752 Level | Description | Use Case |
| Levels 1 to 3 | Materials of 0.25 inches that can protect against three shots from small- to high-caliber handguns, up to a .44 Magnum. These UL 752 levels provide adequate protection against multiple shots from handguns. | Good enough for gas stations, convenience stores, banks and high-occupancy public buildings, where robbers may carry handguns. |
| Levels 4 to 8 | Materials of 0.25-inch thickness that can safeguard against five shots from automatic weapons, semiautomatic rifles and high-caliber rifles, firing ammunition of less than 2-inch thickness. These levels deliver standard rifle protection. | Suitable for government facilities, especially embassies whose staffers face grave threats in hostile countries from terrorists and enemy combatants. |
| Levels 9 to 10 | Materials that provide protection against armor-piercing rifle-fired bullets. These levels can protect against an M2 assault rifle or a .50 caliber vehicle-mounted attack in your home. | Usually used for military applications, such as nuclear facilities and bunkers. |
Consider Your Environment
Your location and lifestyle should influence your high-security door’s ballistic resistance level.
If you live or operate a business in an urban area, a security door designed for handgun protection may be enough. If you reside in the country or a high-risk community where law enforcement is unreliable, a steel-reinforced door optimized for rifle protection can provide you with peace of mind.
Think About Forced Entry, Not Just Ballistics
Forcible entry protection is just as crucial as bullet resistance. Most burglars would attempt to kick and jimmy locked doors using various tools first to gain access, rather than shooting, so yours should be able to keep intruders at bay.
Aside from bullet-resistant armor, your security door system should have internal structural steel, a multipoint locking mechanism and reinforced frames. Combining these features eliminates any weak points that offenders can exploit. Integrating Hidden Door Store’s SecuriWall™ panels into your space can make your safe or panic room more impregnable.
Evaluate How You Will Use the Door
Door usage determines whether your ballistic door requires concealment. Exterior commercial and residential security doors generally don’t need camouflage to mark the property’s entrance and exit for traffic control.
However, you may need a hidden door when concealing a hideout. A secret door disguised as a bookcase, mirror, hutch, wine rack, linen closet or shoe rack with ⅛-inch gaps or less across the floor can effectively obscure the entrance to your safe or panic room. An armored door that can hide in plain sight without arousing suspicion doesn’t have to stop bullets to begin with.
Weigh Budget vs. Protection Needs
The greater the desired bullet resistance, the more expensive the security door becomes. Higher UL levels require tougher materials and more rigorous testing standards.
Moreover, customization can drive up prices. One-of-a-kind units are more challenging and expensive to get certified, whereas standardized designs are the opposite. Third-party laboratories can receive duplicates of doors with standard features, allowing units with similar components and assemblies to get the same ratings.
Hidden Door Store provides expert guidance to help you select a ballistic door that meets your specific needs and fits your budget.
Factor in Future Needs
High-security home features — especially secret doors with bullet-resistant armor — are usually set-and-forget. Think with foresight to avoid the need to relocate your unit after installation.
Incorporate home improvement plans, such as a remodel to modify your space’s layout or a safe room addition. Also, consider the future threats you may face to determine the appropriate ballistic door design.
Look at Verified Testing and Certifications
Ballistic doors aren’t equal — and not just because they have different bullet resistance ratings. Seek compliance testing and non-UL third-party stamps of approval when comparing high-security doors.
Hidden Door Store offers independently verified high-security door models that meet some or all of these standards:
- FE5 or FE15 for forced entry resistance
- ift Rosenheim EN1627 for burglary protection
- ift Rosenheim EN1191 for long-term durability
- ift Rosenheim certifications thermal insulation, sound insulation, and/or water and wind resistance
Ask About Weight, Installation and Structural Requirements
Hidden Door Store offers high-security doors rated for either UL Level 3 or 8. Products with higher bullet resistance ratings are typically heavier and may require structural reinforcements and specialized installation methods, which vary by situation.
Choosing a ballistic door for your property ensures that the door frame can handle the unit’s weight and the walls won’t collapse due to the added security load. It reduces hazards during installation, allowing you to set it up correctly and safely. It should be light enough for everyone to enable both children and adults to use it effortlessly if necessary.
SecuriWall’s ballistic armor can consist of UL Level 3, 5 or 8 panels. This armored wall is modular, rendering installation convenient.
