    FE/BR Doors


    What is FE/BR?


    FE/BR, sometimes designated as FEBR, is an abbreviated version of the term Forced Entry and Ballistic Resistant or Forced Entry and Bullet Resistant. FeBr doors are tested using standardized ratings that describe how they withstand various levels of force exerted upon them by people and breaching tools as well as how capable they are at protecting against firearms.


    What is a FE/BR door?


    FE/BR doors are designed to protect against two categories of threat – people, machines, or tools attempting to forcibly open the door and projectiles fired from weapons with the goal to penetrate the door. Non-FEBR products may protect against one of these threats but not both.


    What materials is a FE/BR door made of?


    FE/BR doors are typically made of steel or aluminum but can use other materials as well, including wood or composites like fiberglass. The gauge of the material, the thickness of the door, and the qualities of the hardware all determine the length of time an entry can withstand a given threat.


    What’s the difference between residential doors and FE/BR doors?


    FE/BR doors use heavier gauge metal and more robust hardware than residential doors because they must resist greater force that can be exerted by attack teams armed with breaching tools. Additionally, they must also undergo ballistic resistant testing to withstand the force of a bullet without penetration. This two-fold protection makes FE/BR doors more appropriate for use in government, military, and other buildings at greater risk of becoming targets of hostile attack. Like FEBR windows, the additional materials required for such protection make FE/BR doors more expensive and, in some cases, less aesthetically pleasing than doors designed for retail and office building applications.


    How are FEBR doors rated?


    FEBR doors are rated by the U.S. Department of State (US DOS), ASTM International (formerly American Society for Testing and Materials), and UL (formerly Underwriters Laboratories). Within the US DOS standard SD-STD-01.01 Rev G (amended), doors are confirmed to have withstood assault by a specific weapon for a particular duration of time. ASTM and UL also have levels of protection determined by how long a door can withstand force from specific weapons and quantifiable force for a length of time.


    How are FEBR doors tested?


    FE/BR doors are tested to determine not only how long they can withstand a 2-6 person attack using breaching tools, but also how they perform during the same tests used for ballistic doors -- namely, how effective they are at resisting penetration by a firearm discharge. Simply put: does the door prevent a bullet from disabling it and how long will the door hold off attack using various breaching tools such as crowbars, wedges, saw and sledgehammers to name only a few. Given these testing requirements, one can readily see that FEBR doors are far more protective than the attack resistant product.


    Is attack resistant the same as FE/BR?


    No. Attack resistant doors are tested differently, focusing less on stopping a bullet and more on being able to continue to operate properly and secure the doorway AFTER being shot multiple times (up to 60 rounds). Simply put: does the door still work and remain locked to prevent entry by an intruder.


    Where can I find FEBR doors?
