Smoke Doors
Smoke Doors – Built to Code, Built to Last
At Paraparaumu Doors + Joinery, we manufacture custom smoke control doors that meet the highest safety standards and are fully compliant with the New Zealand Building Code (NZBC).
All doors are made onsite and to order, ensuring a tailored solution for your project, whether residential, commercial, or industrial.
Compliance & Certification
Our smoke doors are designed and built in accordance with NZBC Acceptable Solutions, specifically Appendix C, C6.1.2, which outlines requirements for smoke separation in buildings.
Key compliance features include:
-
Self-closing mechanisms (C6.1.4) – All doors must close automatically and reliably
-
Smoke seals – Installed in continuous contact with the door, slotted into the jamb to eliminate gaps
-
No sill seals required – But optional automatic drop seals (e.g., RP8) can be fitted
-
Solid core construction – Each door leaf is 38mm thick for durability and performance
-
Vision panels – Optional, with cutouts no closer than 150mm from any edge
-
Clearance tolerances:
-
Leaf to frame: max 3mm
-
Leaf to leaf: max 5mm
-
Leaf to floor covering: max 10mm
