Welcome to Pro Flame Limited
We are Auckland’s premier specialists in passive fire protection, dedicated to securing structural integrity through precision engineering. Our expert team provides end-to-end solutions, from high-performance penetration seals and cavity barriers to intumescent steel coatings. We take pride in delivering meticulous craftsmanship that ensures every building meets stringent safety codes. Whether you require complex installations or urgent compliance repairs, Pro Flame Limited offers the technical expertise to protect your assets and occupants.
Penetration Firestop
Our penetration firestop service focuses on sealing openings created by pipes, cables, and other service penetrations in walls, floors, and ceilings. Using high-quality collars, sealants, or fire-rated batts, we prevent the spread of fire and smoke between building compartments. This critical fire protection measure ensures the integrity of your structure is maintained, protecting both occupants and property while meeting all relevant building codes and fire safety standards.


External Cavity Barrier
External cavity barriers are installed to prevent vertical fire spread within façade cavities, which is a requirement under many building codes. Our team carefully places fire-resistant materials within these gaps to block flames and smoke from moving up the exterior of your building. This essential protection enhances your structure's fire safety, reduces risks to occupants, and ensures regulatory compliance, giving you peace of mind for both new and existing buildings.
Intumescent Paint
Intumescent paint is applied to structural steel to provide a critical layer of fire protection. When exposed to high temperatures, it swells and forms a thick, insulating foam that protects the steel from heat, helping maintain the building’s structural integrity during a fire. Our team ensures correct application thickness and coverage, delivering reliable fire resistance that meets code requirements while safeguarding both the property and the people inside.


Fire Door Sealant and Fire-Rated Duct Wrapping
We ensure fire doors are properly sealed with approved fire-rated sealants, addressing common defects that compromise safety. For ducts, particularly kitchen extract systems, we wrap them with foil-faced, fire-rated insulation to prevent fire and smoke from spreading between areas. Both services are essential for containing fires and maintaining compartmentation within buildings. Our skilled team delivers precise installations that protect occupants, preserve property, and comply with all fire safety regulations.
BWoF Repair
If your building has failed a Building Warrant of Fitness (BWoF) inspection due to fire safety issues, our team can help. We assess the property, identify defects, and implement corrective solutions such as firestopping, barriers, or door seal repairs. By addressing these issues promptly and effectively, we restore compliance with fire safety standards, helping your building pass inspections while keeping occupants and assets protected.
