The Role of Air Sealing in Fire Compartmentation Performance
Effective Fire Compartmentation Safety Surveys ensure that a building’s passive fire protection measures perform as intended. However, one often-overlooked factor is air sealing. Gaps, cracks, and unsealed penetrations can allow smoke, toxic gases, and even flames to bypass compartment lines — undermining safety and compliance.
Why Air Sealing Matters in Passive Fire Protection
Air sealing prevents the uncontrolled movement of air, smoke, and heat between compartments during a fire. Even the smallest openings can compromise Passive Fire Safety systems, meaning lives and property are put at greater risk.
Common Weak Points in Fire Compartmentation
- Service Penetrations: Cable trays, pipework, and ductwork passing through walls and floors must be sealed with appropriate Fire Stopping Installations.
- Junctions and Gaps: Poor sealing where walls meet ceilings or floors can create pathways for smoke and heat transfer.
- Inadequate Maintenance: Over time, seals and fire-rated materials can degrade, requiring inspection and replacement.
Air Sealing and Regulatory Compliance
For UK buildings, proper sealing of compartmentation is essential to meeting the requirements of Approved Document B and Passive Fire Protection Companies must ensure materials are compliant with Building Regulation 7. All work should be carried out by contractors who are Accredited by BM Trada.
Integrating Air Sealing into Passive Fire Protection Services
Air sealing works hand-in-hand with other Passive Fire Protection Services, such as Steel Fire Protection and Buildings and Fire Safety measures. When designed and installed correctly, air sealing helps maintain compartment integrity for the full fire resistance period.
How LPP Fire Protection Can Help
At LPP Fire Protection, we provide expert advice, installation, and inspection services to ensure your building’s compartmentation remains fully compliant. We work closely with developers, contractors, and facilities managers to deliver sealing solutions that are tested and proven for fire safety performance.
Conclusion
Air sealing is not just about energy efficiency — it is a critical part of maintaining the effectiveness of fire compartmentation. By addressing potential leakage points, you enhance safety, meet compliance standards, and protect lives and property in the event of a fire.
