How to recognize an armored door?
Distinctive visual characteristics
Contrary to popular belief, an armored door is not only recognized by its weight or thickness. Here are the key elements to identify a genuine armored door:
Steel core: The heart of an armored door consists of one or more steel plates. This metal structure may be visible on the door edges or hidden under decorative cladding.
Reinforced closing system: An armored door must have a multi-point locking system (minimum 3 points, often 5 to 7 points). These locking points are distributed along the entire height of the door, unlike a standard lock that only locks at one central point.
Armored frame: A proper armored door is always accompanied by a reinforced steel frame. This detail is crucial because there’s no point having a resistant door if the frame can be easily deformed or broken.
Secure hinges: Armored door hinges are either hidden (invisible hinges) or equipped with anti-removal pins that prevent door removal even if the hinges are accessible.
Technical signs to verify
Official certification: Any proper armored door must have A2P (Assurance Prévention Protection) certification or equivalent. This certification is issued by independent organizations like CNPP.
Thickness and weight: An armored door generally measures between 50 and 80 mm thick and weighs between 80 and 200 kg depending on its protection level. For comparison, a standard door weighs about 30 to 40 kg.
Quality finishes: Modern armored doors offer very varied finishes (wood, metal, composite) that perfectly mask their security nature. The absence of attractive finishes doesn’t necessarily mean it’s an authentic armored door.
How to test the solidity of an existing door
If you want to evaluate the resistance of your current door, here are some simple tests:
Sound test: Tap lightly on different points of the door. An armored door produces a dull, muffled sound, while a hollow door resonates more sharply.
Observation of locking points: Count the number of points where your key activates a locking mechanism. A standard door has only one, an armored door has at least three.
Frame examination: Check if the door frame shows visible metal reinforcements or if its construction seems particularly robust.
Different types of armored doors
Classification by structure
Solid core armored doors
These doors constitute the top of the range in terms of security. Their internal structure is entirely composed of steel, offering maximum resistance to break-in attempts. The solid core guarantees homogeneous protection over the entire door surface.
Advantages: Exceptional resistance, maximum durability, excellent sound insulation Disadvantages: High weight (up to 200 kg), higher cost, installation constraints
Honeycomb core armored doors
This structure combines steel plates and honeycomb structure in composite materials. It offers an excellent compromise between security, weight, and thermal insulation.
Advantages: Reduced weight, good thermal insulation, interesting quality-price ratio Disadvantages: Slightly lower resistance than solid core
Mixed armored doors
These doors combine different materials (steel, wood, composite materials) to optimize both security and aesthetics. They allow reconciling protection and harmonious integration into the habitat.
Classification by security level
A2P BP1 armored doors
Entry-level, these doors resist about 5 minutes to break-in attempts with common tools (crowbar, screwdriver). They are suitable for low-risk housing or as a complement to other security devices.
Recommended for: High-floor apartments, monitored residences, limited budget
A2P BP2 armored doors
Intermediate level, these doors offer about 10 minutes resistance against more specialized tools (drill, saw). They represent the most popular choice for individuals.
Recommended for: Individual houses, ground-floor apartments, moderate risk areas
A2P BP3 armored doors
Maximum level for individuals, these doors resist about 15 minutes to professional tools. They are recommended for high-value properties or high-risk areas.
Recommended for: Luxury properties, high-crime areas, valuable storage
Classification by opening mode
Classic swing armored doors
The traditional system with inward or outward opening. This is the most common and economical solution.
Sliding armored doors
Modern solution for reduced spaces or specific architectural configurations. The sliding mechanism requires reinforced rails to support the weight.
Pivoting armored doors
High-end system with central pivot, offering smooth opening and contemporary design. Mainly used for prestigious entrances.
Specialized armored doors
Fire-resistant armored doors
These doors combine break-in protection and fire resistance. They are mandatory in certain buildings and recommended for communicating garages.
Acoustic armored doors
Specially designed for sound insulation, they integrate absorbent materials while maintaining their security properties.
Custom armored doors
For non-standard openings or specific architectural requirements, custom doors allow adapting security to all configurations.
A2P certification: the quality guarantee
Understanding A2P certification
A2P (Assurance Prévention Protection) certification constitutes the absolute reference for armored door security in France. Created by French insurers, it guarantees that the product has been tested according to rigorous protocols by independent organizations.
History and legitimacy: Established in the 1980s, A2P certification is recognized by all French insurance companies. It often constitutes a sine qua non condition to benefit from certain guarantees or premium reductions.
Certifying bodies: CNPP (Centre National de Prévention et de Protection) is the main organization, but other approved laboratories can issue this certification.
A2P resistance tests
Test protocols: A2P tests reproduce real break-in attempt conditions. They evaluate the resistance of the door + lock + frame assembly against different attack methods:
- Force attacks (blows, pressure)
- Drilling and sawing
- Pulling and twisting
- Lock picking and bumping
Test conditions: Tests are conducted under controlled conditions, with standardized tools and precise protocols. Each level (BP1, BP2, BP3) corresponds to a resistance time and a defined tool set.
Evaluation criteria: Beyond simple time resistance, tests evaluate:
- Structural integrity after attack
- Mechanism functioning
- Fixing point resistance
- Quality of materials used
Certification levels explained
A2P BP1 (Door Block level 1)
- Resistance time: 5 minutes minimum
- Attack tools: Common hand tools (crowbar, screwdriver, hammer)
- Recommended use: Basic protection, secure apartments
- Approximate cost: €800 to €1,500
A2P BP2 (Door Block level 2)
- Resistance time: 10 minutes minimum
- Attack tools: Mechanized tools (drill, hand saw, shears)
- Recommended use: Standard protection, most homes
- Approximate cost: €1,200 to €2,500
A2P BP3 (Door Block level 3)
- Resistance time: 15 minutes minimum
- Attack tools: Power tools (grinder, percussion drill, jigsaw)
- Recommended use: Enhanced protection, high-value properties
- Approximate cost: €2,000 to €4,000
Complementary certifications
NF (French Standard): Guarantees manufacturing quality and product durability.
CE (European Conformity): Attests conformity to European safety standards.
Specialized certifications: Fire resistance (EI), acoustic insulation (Rw), thermal performance (Ud).
Resistance levels explained
Resistance test methodology
Break-in attempt simulation: Approved laboratories faithfully reproduce methods used by burglars. These tests are based on police statistics and analysis of real break-in attempts.
Evolution of attack methods: Test protocols constantly evolve to adapt to new techniques used by criminals. The arrival of powerful cordless tools notably led to toughening requirements for BP2 and BP3 levels.
Detailed analysis by resistance level
BP1 Level – Protection against opportunism
This level aims to discourage opportunistic break-in attempts. Burglars using basic tools will generally give up when faced with 5 minutes of resistance.
Tested attack methods:
- Shoulder or foot forcing
- Crowbar use (30 to 40 cm)
- Screwdrivers of different sizes
- Carpenter’s hammer (300 g)
- Pliers and tongs
Potential weak points: Against a determined burglar with electric tools, this level may prove insufficient.
BP2 Level – Recommended standard protection
This level meets the needs of most individuals. It effectively deters “average” burglars who have more sophisticated tools.
Tested attack methods:
- All BP1 level tools
- Electric drill (up to 750 W)
- Hand saw and metal blade
- Shears up to 600 mm
- Metal files and rasps
- Chisels and punches
Proven effectiveness: Statistics show that 80% of break-in attempts are abandoned before 10 minutes.
BP3 Level – Maximum protection
The highest level for individuals, reserved for high-risk situations or high-value properties.
Tested attack methods:
- All tools from previous levels
- Angle grinder (up to 1200 W)
- Percussion drill (up to 1200 W)
- Electric jigsaw
- 1.5 kg sledgehammer
- Professional lock picking tools
Important note: Beyond 15 minutes, detection risks are very high, which explains why this level constitutes the maximum for individuals.
Factors influencing real resistance
Installation quality: A poorly installed BP3 door can offer lower resistance than a properly installed BP1 door. Fixing in a load-bearing wall, perfect alignment, and installation sealing are crucial.
Support condition: A wall in poor condition, failing anchorages, or a weakened structure can compromise armored door effectiveness.
Maintenance: Lock mechanisms require regular maintenance. A poorly maintained lock can facilitate picking or bumping.
Human factor: Real resistance also depends on occupant habits (door properly locked, keys not accessible, etc.).
Specialized complementary tests
Aging tests: Doors undergo opening/closing cycles (generally 200,000 cycles) to verify their resistance over time.
Climate tests: Resistance to temperature variations, humidity, and weather.
Functionality tests: Verification of proper operation after resistance tests (smooth opening, maintained alignment).
