Security doors

RC2 and RC3 are burglar resistance classes under the European standard EN 1627. RC2 doors are tested against at least 3 minutes of active attack with simple tools, while RC3 doors are tested for 5 minutes, including heavier tools such as a crowbar. RC3 therefore offers a higher level of protection.

For a typical flat in an apartment block, a certified RC2 security door is usually enough. For greater security we recommend RC3, which offers higher resistance to break-in attempts. When choosing, also consider where the flat is, how exposed it is and any requirements from your insurer.

The EN 1627 standard sets out the requirements and burglar resistance classes for doors, windows and other building elements. Classes RC1 to RC6 indicate different levels of protection, depending on the type of attack and the tools used. Certification confirms that the product's burglar resistance has been tested using the prescribed procedures.

For a standard replacement of a flat's front door, the building manager's consent is usually not needed, as long as no common parts of the building are affected. If the replacement affects shared structures, the building's appearance or required fire safety, additional rules apply. Before replacing the door, we recommend checking the building rules and talking to the building manager.

Yes, a good-quality security door can noticeably reduce noise coming in from corridors and stairwells. Sound insulation depends on the door construction, core, seals and correct installation. Some Padilla models achieve sound insulation of 30 to 40 dB, depending on the version.

A security door is not automatically a fire door. To be fire-resistant, it needs an additional, properly tested and classified version, such as EI30 or EI60. Padilla also offers security doors with fire resistance, which protect against both break-ins and the spread of fire.

Yes, some security doors can be unlocked electronically with a code, card, fingerprint or smartphone. Padilla also offers versions with electronic locks. It is important that the chosen system is compatible with the door and does not affect its certified security.

A transom is an additional panel above the door leaf that fills the space in taller door openings. It can be solid or glazed, depending on the version. It is most often used in older buildings and in openings that are taller than standard. On a security door, it must keep the whole assembly properly secure.

Yes, on most security doors you can replace just the lock cylinder, without changing the whole lock or the door. It is important to choose a good-quality security cylinder of the right size. On a certified door, the new cylinder must maintain the required level of burglar protection.

Spanish manufacturer Padilla specialises in metal security, fire-rated and technical doors. Dierre is an Italian manufacturer focused mainly on security doors, with a range of design and technical solutions. Both offer certified security versions; the choice depends on the model, the properties you need and how the door will be used.
