Vienna records thousands of residential break-ins every year — and in over 80% of cases the entrance door is the attack point. A standard-tested security door per EN 1627 is the single most effective measure against burglary.

Over 300 Google reviews at 5.0 stars, trade licence GISA 38955860 — certified quality from one source.
Resistance classes compared: RC2, RC3 and RC4
The European standard EN 1627 defines how long a security door must withstand defined break-in tools. Three classes are relevant for Vienna apartments and commercial properties — the right choice depends on location, use and protection requirements.
| Feature | RC2 / WK2 | RC3 / WK3 | RC4 / WK4 |
|---|---|---|---|
| Tested resistance time | 3 minutes | 5 minutes | 10 minutes |
| Attacker profile | Opportunist, simple tools | Experienced burglar, crowbar | Professional, power tools |
| Locking points | 3-point | 5- to 7-point | 7-point+, steel core |
| Cylinder class | Security cylinder | High-security cylinder | Highest cylinder class |
| Recommended use | Apartments, upper floors | Ground floor, houses, offices | Villas, jewellers, high security |
| Price incl. installation from | approx. €1,500 | approx. €2,500 | on request |
Most Vienna apartments achieve solid protection with RC2. For ground-floor units, houses or commercial premises we recommend RC3 — these locations carry the highest burglary risk. RC4 suits properties with special requirements such as jewellery shops or villas.

Which security level do you need?
Assess the property location
Ground floor, basement or street-level access? The break-in risk is elevated — RC2 minimum, RC3 recommended. From the first floor upwards, RC2 is usually sufficient.
Evaluate the use
Private apartment or commercial property? For offices handling sensitive data, medical practices or retail spaces, RC3 is the recommended minimum.
Consider valuables
Jewellery, art, cash or IT infrastructure? The higher the value, the higher the sensible protection class. Above certain thresholds, insurers may require RC3 or RC4.
Assess the surroundings
Quiet residential area or busy location? In high-traffic areas, visibility acts as a deterrent — RC2 often suffices. In secluded locations, intruders have more time.

How to identify a genuine security door
Not every door marketed as "secure" is standard-tested. Check these features before buying — or let us inspect what you already have.
Checklist: Identifying a certified security door
These five points distinguish a certified security door from an ordinary door with a marketing premium:
Type plate with RC class present
Every tested security door carries a plate showing the resistance class (RC2, RC3 or RC4) and reference to EN 1627. If this plate is missing, the door is not standard-tested.
Test certificate from a recognized body
A certificate from IFT Rosenheim, Holzforschung Austria or a comparable body confirms the testing. Ask to see this document — reputable manufacturers always supply it.
Installation by a GISA-registered trade business
The best door is worthless if installed incorrectly. Ensure the installer holds a valid trade licence. Our GISA number: 38955860 — verifiable at gisa.gv.at.
Frame and door leaf form a matched unit
In a genuine security door, frame and door leaf are designed as one system. If only the leaf is replaced and the old frame kept, the entire RC rating is void.
Security cylinder with key card
The cylinder must match the RC class. Security cylinders with a key card prevent unauthorized key copying — essential for any security door from RC2 upwards.
Insurance premium discount for certified doors
Premium savings: 5–15% with many insurers
Many Austrian household insurers offer a premium reduction when a standard-tested security door (RC2 or higher) is documented. Savings typically range from 5–15% of the annual premium. After installation we provide all paperwork: test certificate, installation confirmation and manufacturer documentation. Ask your insurer about the conditions — in many cases the door pays for itself through premium savings alone.
