Certified armored door installation BP1 • BP2 • BP3 in Paris

In Paris, where burglaries are frequent, a classic door—even reinforced—no longer suffices to guarantee reliable security. Choosing a certified armored door means opting for protection tested and validated by independent organizations, notably the CNPP (National Center for Prevention and Protection). Unlike so-called “armored” doors without real validation, a certified door benefits from the NF A2P label, which attests to its resistance to the most commonly used break-in techniques: crowbar, drilling, lock picking, sawing…

This certification is the result of rigorous laboratory tests, carried out on the entire door block: leaf, lock, locking points, hinges, etc. The result: the security level is measured precisely, and you have the assurance that your door will hold for at least several minutes against a targeted attack. It is an essential guarantee, not only for your peace of mind but also to be eligible for home insurance requirements.

👉 Choosing a certified armored door is not just about reinforcing an entrance: it is about sustainably securing your family, your belongings, and your peace of mind in an exposed urban environment.

In Paris, whether it is an existing door reinforcement or the installation of a complete armored door unit, the NF A2P certification defines the level of resistance against break-ins. Three levels coexist: BP1, BP2, and BP3.

• 
  BP1 guarantees resistance of at least 5 minutes against attacks, with a steel structure of 20 to 25/10th. These door units are generally equipped with A2P★ certified locks, with 3, 5, or 7 locking points. This is the typical combination to effectively secure a Parisian apartment.
  
• 
  BP2, the structure remains the same, but the lock is more efficient: often A2P★★, sometimes even ★★★ with some manufacturers. This level is recommended for ground floor housing, houses, or shops.
  
• 
  BP3 corresponds to enhanced protection. The steel thickness increases to 40/10th, with an increased number of locking points (7 to 9 points), and a A2P★★★ certified lock, such as the Serenis 710 from Picard Locks or the Fichet Alicea XP from Fichet . These configurations are ideal for valuable properties or high-risk environments.
  

Choosing the right certification level means adapting your security to Parisian realities, while respecting the requirements of home insurance.

In Paris, the choice of an NF A2P certified armored door depends both on the type of housing, its exposure to risks, and the level of comfort sought. In an apartment located on an upper floor, a BP1 certified door with A2P★ lock is generally sufficient to meet common security requirements. However, for a ground floor, a top floor with a terrace, or a sensitive neighborhood, it is better to opt for a BP2 or BP3 door, designed to resist more aggressive break-ins.

In a detached house, security must cover direct access from the street: the minimum recommended is a BP2 door with A2P★★ or ★★★ lock. For a shop or an office, a BP3 armored door is strongly recommended.

But security is not always enough: the certification level also affects acoustic comfort. In Paris, where noise pollution is constant, sound insulation becomes an essential criterion. At Picard Serrures, the Diamant 10 armored door (BP1) achieves 42 dB of insulation, while the Diamant 20 (BP3) offers up to 47 dB. A real difference in daily life.

Choosing the right armored door means securing your home while improving your quality of life in Paris.

The price of a security door or custom armor in Paris can vary depending on many criteria. Between the level of security, aesthetic options, and integrated equipment, each project is unique. The price of a custom-made door armor, equipped with a A2P one-star certified lock, starts at €1850 including tax for supply only. For complete armored door blocks (door + reinforced frame), the first certified models start at €2390 including tax, while the protection of a cellar can start from €799 including tax.

The price can quickly change depending on the number of locking points, the type of keys (classic, patented, protected, with identity control), the door certification (BP1, BP2, BP3), but also depending on the chosen exterior style: moldings, RAL paint, oak or mahogany finish… Every detail counts. Accessories can also influence the final price: security door stopper, connected peephole, reinforced handles, door closer, Tedee connected keypad or cylinder, etc.

To get a clear and adapted price for your home, the easiest way is to send us some photos of your current door. Our team will respond within 24 hours with a free and personalized estimate.

Door reinforcement is often a more economical solution, as it allows you to keep the existing door, while adding a steel structure and an A2P certified lock. It is an excellent option when the current door is made of quality solid wood, a material sometimes difficult to find with modern manufacturers. However, if the original door is too damaged, too thin, or already weakened, it is often better to start with a complete armored door block, which is stronger and more durable.

Reinforcement involves installing a new Z-shaped metal frame, as well as a U-shaped steel sheet that wraps around the existing door. The choice of the multipoint lock is up to the customer: A2P★, A2P★★, or A2P★★★ depending on the desired level of security.

But the most striking difference remains the sound and thermal insulation. Even a well-installed reinforcement can never compete with a high-end door block like the Diamant models from Picard Serrures, which reach 80 to 90 mm thickness, with integrated insulating materials. On a Diamant 30, sound insulation reaches up to 47 dB; the Diamant 10 and 20, with fireproof option, offer about 44 dB. Conversely, a classic reinforcement remains on average between 20 and 30 dB, and is generally not officially tested like certified door blocks.

The difference is therefore as much technical as budgetary: a **Diamant 30 armored door with A2P★★★ often exceeds €4950, while a custom reinforcement with A2P★★★ lock stays around €2950. That is why each situation must be carefully studied.
