NZ Fire Doors
Smoke & Fire-Rated Doors For Commercial & Residential Projects Across The Waikato
Specified, supplied, and supported to meet New Zealand fire requirements
At Montage Doors, we work with New Zealand’s leading smoke and fire door manufacturers to supply compliant fire-rated door systems for commercial buildings, apartments, and selected residential applications.
Our role is to help builders, architects, and project teams select the correct fire door system for each location, ensuring the rating, components, and documentation all line up for consent and inspection.
Fire ratings explained
Fire doors are rated by how long they can resist fire exposure. Common fire resistance ratings include:
30 minutes
60 minutes
90 minutes
The required rating depends on the building design and the fire separation the door sits within. The rating applies to the full door system, not just the door leaf.
Fire doors are complete systems
A compliant fire door is a tested system made up of multiple parts, including:
Fire-rated door leaf
Approved frame
Intumescent and smoke seals
Fire-rated hinges and hardware
Closers and latching hardware (where required)
Substituting or changing components can affect compliance. That’s why fire doors must be supplied exactly as tested and approved.
Installation is critical: Even a correctly specified fire door can fail if it is not installed properly. Clearances, fixing methods, seals, and hardware placement all play a part in how the door performs in a real fire.
Fire Door FAQ's
What is a fire door?
A fire door is a tested door assembly designed to slow the spread of fire and smoke for a set period of time. During a fire, it helps contain the fire within a compartment, giving occupants more time to exit safely and helping limit damage to the building.
Fire doors form part of a building’s passive fire protection system and are commonly required in:
Commercial buildings
Apartments and multi-unit housing
Offices, schools, hospitals, and care facilities
Stairwells, corridors, plant rooms, and fire separations
How does a fire door slow the spread of fire?
Fire doors use fire-resistant materials and are designed to remain in place during a fire. When exposed to heat, intumescent seals expand to close gaps around the door, helping block flames and smoke.
Are fire doors fireproof?
No. Fire doors are fire-resistant, not fireproof. They are tested to withstand fire for a specific time period, such as 30, 60, or 90 minutes.
Does fire door hardware need to be fire-rated?
Yes. Hinges, locks, latches, closers, and other hardware must be approved for use with fire doors. Standard hardware may fail early in a fire.
Can fire doors include glass?
Yes, but only fire-rated glazing that has been tested as part of the door system. Standard glass cannot be used in a fire door.
Can fire doors be painted?
Fire doors can be painted or finished, but only with approved coatings and within allowable thickness limits. Excess paint build-up or unsuitable products can affect performance.
Do fire doors have to self-close?
In many commercial settings, yes. Self-closing devices help make sure the door is closed during a fire, which is essential for it to work properly.
Can fire doors be altered after installation?
No. Cutting, drilling, or modifying a fire door without approval can void the fire rating. Any changes must align with the tested system.
How do I know what fire rating is required?
The required fire rating is usually listed on the building plans or fire report. If you’re unsure, we can help review the project requirements before supply.
