In short, no. It’s crucial to ensure that every detail is carefully considered with the architect during the design and specification phase. Key factors to consider include the slab and flooring build-ups, trim, rough opening sizes, and the proper calculation of all fire door components. This ensures that the leaf size is accurately determined, allowing the door manufacturer to create a custom-made fire door system that fits perfectly and avoids installation issues.
According to NZS 4520:2010 regulations, any modifications or alterations to a fire door must be approved by the manufacturer to ensure continued compliance with fire safety standards. Unauthorized changes such as cutting, drilling, or installing non-compliant hardware can severely compromise the door’s fire resistance and render it non-compliant. The consequences of making unauthorized modifications include voiding the fire rating certification, creating serious safety risks, potential legal and insurance issues, building code violations, and endangering life safety in the event of a fire.
To maintain safety and compliance, always contact the manufacturer directly for any required modifications. They can assess the situation and offer expert advice tailored to your needs. Additionally, only use approved installers and technicians and ensure that all hardware or components are from the manufacturer’s approved hardware list.
