Passive Fire Protection Services
Hitachi Energy Substation secured with TekSeal’s Passive Fire Protection solutions.
Building safety depends on more than fire alarms and sprinklers. Passive fire protection creates permanent barriers within structures that limit fire and smoke movement between spaces, protecting occupants and preserving building integrity. These systems work silently in the background, meeting New Zealand Building Code Clause C requirements for fire safety, including restrictions on fire spread (C3), safe evacuation pathways (C4), and maintaining structural stability during fire events (C6).
TekSeal delivers specialized Beele Engineering passive fire installations throughout New Zealand, from new construction projects to building upgrades. Our work addresses seismic considerations in regions like Canterbury, where systems must withstand both fire and earthquake forces.
We handle complex commercial environments including cool stores where refrigeration chemicals create additional fire risks, and high-voltage electrical substations with arc flash and electrical hazards. Our installations integrate seamlessly with architectural plans, and we provide complete documentation to support building consent applications and ensure long-term system reliability.
The Importance of Passive Fire Protection
In high-risk settings like cool stores, plant rooms, and high-voltage substations, fire escalates quickly through penetration gaps, chemical hazards, or electrical risks. Passive systems confine fire to its origin point, delivering up to 4 hours of resistance per AS/EN/IMO standards, providing vital response time and reducing structural failure risk under Clause C6.
Across New Zealand, particularly in Christchurch and Canterbury, post-earthquake fire research highlights the need for resilient systems that endure seismic activity while preserving integrity. Passive protection extends beyond compliance, forming a strategic layer that complements active systems, lowering insurance exposure and supporting operational continuity for architects and consultants.
Our Passive Fire Protection Installation Process
We install Beele Engineering’s certified systems, tested to international standards (EN, IMO, UL, ISO) for fire, smoke, and gas containment in demanding conditions. Our nationwide work focuses on complex commercial locations, including MCC rooms, refrigeration-intensive buildings, and high-voltage electrical substations, with complete compliance documentation for NZ Building Code consents.
Fire Penetration Sealing
Penetrations for pipes, cables, and ducts create major risks by allowing fire and smoke passage. TekSeal seals these nationwide using Beele’s NOFIRNO system, a multi-purpose rubber sealant that expands under heat to form a gas and watertight barrier, rated A0 to A60/H0 to H120 for up to 4 hours of resistance.
Appropriate for cool stores, high-voltage substations, and commercial construction across NZ, it prevents corrosion, accommodates seismic movement, and ensures Clause C3 compliance, with straightforward retrofitting for design flexibility.
Intumescent Wrap Systems
Plastic pipes melt during fire, breaching compartments. We install Beele’s Crusher wrap and Rise cable sleeves which crush plastic pipes and seal melted cable insulation in voids, delivering excellent firestopping performance. Vibration resistant and modular, they suit high-risk zones like MCC rooms near refrigeration or high-voltage substations with electrical equipment, surpassing NZ safety standards and supporting Clause C4 for safe evacuation.
Fire Rated Sealant Applications
Joints, cracks, and service gaps need resilient sealing to withstand extreme temperatures. TekSeal applies Beele’s NOFIRNO compound nationwide, flexible curing sealants with smoke tight and acoustic properties, ISO 9001 certified for durability in seismic regions. Compatible with substrates including concrete, steel, and GRP, they deliver dependable protection under Clause C, with testing for harsh conditions across NZ, including high-voltage installations.
