RC3 Entrance Doors – A New Dimension of Security and Aesthetics

In modern architecture, entrance doors are no longer merely passages between spaces. They define the character of a building, its style, and its prestige. But above all, they serve a vital function – security, which must go hand in hand with functionality, comfort, and aesthetic appeal.

Doors built on the R-Core 90 mm profile from the Signature collection not only meet the highest standards of modern design but also achieve RC3 certification, setting a new benchmark for premium entrance doors.

What is RC3?

RC3 (Resistance Class 3) is an internationally recognized standard for burglary resistance, defined by EN 1627.

Entrance doors with RC3 certification:

  • Withstand at least 5 minutes of burglary attempts,

  • Are tested with professional tools such as crowbars, hammers, and power drills,

  • Provide effective protection against intruders using both skill and time.

In practice, RC3 doors offer a real, measurable barrier that ensures peace of mind for homeowners and residents.

Why RC3 Matters

Statistics show that intruders most frequently target doors and windows. RC3-rated doors provide:

  • Extended protection time – intruders are discouraged by the resistance,

  • Psychological comfort – residents feel safer,

  • Investment protection – safeguarding both property and value.

RC3 doors are ideal for single-family homes, apartments, and high-security buildings.
