Integral Fire and Smoke Barrier for Life Safety Compartmentation

The Certified 2-Hour Fire-Rated Steel Door & Frame Set is a fully tested and certified assembly designed to compartmentalize a building, preventing the spread of fire and smoke for up to 120 minutes. This critical passive fire protection system protects escape routes (stairwells, corridors), separates high-risk areas, and safeguards property, providing vital time for evacuation and firefighting operations.

Key Features & Benefits:

• Full 120-Minute Integrity & Stability: Certified to withstand standard fire exposure tests (BS 476: Part 22 or equivalent) without collapse, maintaining its barrier function.
• Intumescent Fire & Smoke Seals: Specially fitted seals around the door edges expand dramatically when exposed to heat (approx. 180°C), sealing gaps to block flames, hot gases, and toxic smoke.
• Solid Core Construction: The door leaf is constructed from galvanized steel skins filled with a non-combustible mineral wool core, providing rigidity and insulation.
• Integrated Frame System: Comes with a matching, pre-formed steel frame for correct installation and rated performance. Frame is designed for masonry or stud wall construction.
• Compatible Hardware: Prepared for the installation of a full suite of fire-rated hardware, including a 3-hour rated mortice lock, hinges, and a door closer/holder (sold separately).
• Certification & Labels: Each door is supplied with a permanent certification label detailing its fire rating, manufacturer, and test standard.

Mandatory Applications (By Building Code):

• Fire Escape Staircase Doors
• Separations between building tenancies
• Entrances to electrical switch rooms, generator rooms, and hazardous storage areas.
• Corridor doors in hospitals, schools, and high-rise residential buildings.
• Industrial fire walls and partitions.

Technical Specifications & Compliance:

⚠️ Critical Note: Fire rating is only valid when installed with the correct frame, specified fire-rated hardware, and by an approved installer following manufacturer guidelines.
