Certified vault rooms, strongrooms and vault doors to EN 1143-1
A vault room or strongroom is an armoured space closed off by a certified vault door, designed for the secure storage of large volumes of valuables, documents, archives or works of art. The traditional version consists of a reinforced concrete room into which the vault door is integrated. The thickness, reinforcement and build-up of the walls are determined by the required security level and the resistance grade under EN 1143-1.
An interesting alternative is the prefabricated or modular vault room, built from armoured panels that interlock precisely and are anchored from the inside, allowing a made-to-measure vault room without massive concrete construction. This modular strongroom is considerably lighter, installs quickly and easily — including in existing buildings and on upper floors — and its thinner walls yield appreciably more usable interior space.
In a new build or major renovation, it pays to include the vault room in the design from the start: a certified vault door on a room built on site often offers, in proportion to the volume, more storage space at a lower price than a large free-standing safe. Plan early, and you gain both space and budget.
The range includes certified vault doors and vault rooms from Grade 0 up to Grade 13 under EN 1143-1 — the highest level the standard knows, for banks, cash-in-transit companies and professional value storage. The heaviest versions are available as KB versions: this core-drilling protection (CD) offers additional resistance against attacks with diamond core drills — a very real risk, as the spectacular break-in at a German bank vault in late 2025 demonstrated, where precisely this protection was missing. Fire-resistant vault rooms are also available, purpose-built for the safe keeping of precious collections.
Vault rooms serve widely different environments: jewellers and diamond dealers securing their stock behind a vault door overnight, companies protecting servers or sensitive equipment, and organisations managing extensive archives. For archiving, the vault room is the logical step when individual fire-resistant cabinets no longer suffice: a single secured archive room protects the entire holdings against burglary and — in the fire-resistant version — against fire. Fitted with fixed or mobile shelving, an archive strongroom stores large document volumes compactly and in good order, from notarial deeds and patient records to art collections and heritage pieces.
The vault door itself deserves particular attention. Every door is fitted with high-security safe locks certified to EN 1300, class A, B, C or D — as a key lock, mechanical or electronic code lock, or with biometrics. In the higher grades, up to four locks are often combined on a single vault door, complemented by a time lock preventing any opening outside programmed hours, remote blocking via IP or the alarm system, the four-eyes or six-eyes principle requiring several people to open together, or one-time codes. Some vault doors can additionally be fitted with an internal opening mechanism, allowing the vault room to double as a panic room or secure shelter. For business continuity there are emergency doors — certified to the same resistance grade as the main door — keeping the vault room accessible should the main door fail to open; versions even exist with an emergency hatch integrated into the main door itself. The contents thus remain accessible at all times, without a single concession to security.
Every vault room is a bespoke project: for each enquiry we assess the location, the required volume, the resistance grade and the structural possibilities, and take charge of complete delivery and installation.
