What are RC classes?
RC classes (Resistance Class) are European certification levels that define the burglary resistance of doors, windows and facade elements. They are defined in the EN 1627 standard and range from RC1 (basic resistance) to RC6 (protection against heavy equipment).
RC1 — basic security
RC1 offers resistance against physical force: kicking, shoving and shoulder-barging. Most standard interior doors don't reach this level. Suitable as a first barrier in low-risk environments.
RC2 — the recommended starting point for homes
RC2 is the absolute minimum we recommend for a front door. The door withstands an attack with simple tools (screwdriver, crowbar) for 3 minutes. Insurance companies often require this level for standard policies.
RC3 — premium residential and light commercial use
RC3 withstands a 5-minute attack by experienced burglars using powerful tools (crowbar, hammer, chisel). Recommended for villas, jewellers and offices with valuable assets.
RC4–RC6 — banking and high-risk applications
Classes RC4 to RC6 are intended for banks, jewellers, valuables storage and military installations. They withstand attacks of 10 to 20 minutes using powerful electric tools and grinding discs.
Which class do you need?
The choice depends on three factors: location (urban vs. remote), the value of what you're protecting, and your insurer's requirements. Our advisors carry out a free risk assessment and recommend the most cost-effective solution.
