Passive Fire Protection Services

Passive fire protection systems are integral to building design, containing fire, smoke, and toxic gases within compartments to support structural stability and evacuation. These built-in measures comply with New Zealand Building Code Clause C (Protection from Fire), including C3 (spread of fire), C4 (movement to place of safety), and C6 (structural stability).

At TekSeal, we specialize in high-performance installations using Beele Engineering products, tailored for new builds and upgrades nationwide, including seismic-prone regions like Canterbury.
Our solutions address unique risks in commercial facilities, such as cool stores with refrigeration systems prone to chemical reactions during fires, and high-voltage electric substations with arc flash and electrical hazards. We ensure seamless integration with design plans, providing documentation for consents and long-term durability.

Why Passive Fire Protection Matters

In high-risk environments like cool stores, plant rooms, and high-voltage substations, fire can escalate rapidly due to gaps in penetrations, chemical hazards, or electrical risks. Passive systems contain it to the source, offering up to 4 hours of resistance per AS/EN/IMO standards, buying critical time for response and minimizing structural failure under Clause C6.
Nationwide, with a focus on Christchurch and Canterbury, post-earthquake fire studies emphasize resilient systems that withstand seismic activity while maintaining integrity. Passive protection isn’t just compliance—it’s a strategic layer that complements active systems, reducing insurance risks and supporting operational continuity for architects and consultants.

How We Install Passive Fire Protection

We deploy Beele Engineering’s certified systems, tested to international standards (EN, IMO, UL, ISO) for fire, smoke, and gas containment in harsh conditions. Our nationwide installations focus on complex commercial sites, including MCC rooms, refrigeration-heavy builds, and high-voltage electric substations, with full compliance documentation for NZ Building Code consents.

Fire Penetration Sealing

Penetrations for pipes, cables, and ducts pose significant risks by enabling fire and smoke migration. TekSeal seals these nationwide using Beele’s NOFIRNO system—a multi-purpose rubber sealant that expands in heat to create a gas- and watertight barrier, rated A0-A60/H0-H120 for up to 4 hours of resistance.

Suited for cool stores, high-voltage substations, and commercial builds across NZ, it prevents corrosion, accommodates seismic movement, and ensures Clause C3 compliance, with easy retrofitting for design flexibility.

Intumescent Wraps

Plastic pipes melt under fire, breaching compartments. We install Beele’s Crusher wrap and Rise cable sleeves which crush plastic pipes and seals melted cable insulation in voids delivering outstanding firestopping capability. Vibration-resistant and modular, they’re ideal for high-risk zones like MCC rooms near refrigeration or high-voltage substations with electrical equipment, exceeding NZ safety standards and supporting Clause C4 for safe egress.

Fire-Rated Sealant Installation

Joints, cracks, and service gaps require resilient sealing to resist extreme temperatures. TekSeal uses Beele’s NOFIRNO compound nationwide—flexible-curing sealants with smoke-tight and acoustic properties, ISO 9001-certified for durability in seismic areas. Compatible with substrates like concrete, steel, and GRP, they provide reliable protection under Clause C, with testing for harsh conditions across NZ, including high-voltage installations.
