The Robust 'INNA-DOR' 60 doorset provides protection against fire for up to one hour (60 minutes), whether latched or unlatched, as part of a building’s passive fire protection. Fire doors maintain the fire resistance of the wall as a whole and enable a safe exit in case of emergency.

The construction incorporates appropriate seals around the door leaf perimeter with appropriate fire resistant glass fitted to all vision panels.

Robust has successfully redesigned steel doors away from their original industrial roots to provide a highly cost-effective single solution to fire protection, security, durability and aesthetics. The doors, fitted in internal and external applications in a wide variety of wall constructions, are designed to protect personnel and property from the spread of flames and smoke. Robust doors offer substantial benefits over comparable timber doors in strength, durability and security.

The range has been tested to BS 476 Parts 20 and 22, BS EN 1634 and holds CERTIFIRE certification.
