Joint sealing is crucial where building elements and materials meet, as any gaps make the structure susceptible to leakage. Proper sealing ensures that these joints remain watertight, airtight, and resistant to various environmental factors, thereby maintaining the building's integrity and energy efficiency.

What are penetration seals in passive fire protection, and why are they essential?

Penetration seals, also known as service penetration seals, are passive fire protection systems designed to maintain the fire resistance of building elements—such as walls or floors—where services like cables, cable trays, pipes, or ventilation ducts pass through them.

These seals are crucial because any opening in fire-resistant barriers can allow flames, heat, and toxic smoke to spread into adjoining rooms and areas, potentially leading to uncontrolled fire propagation throughout the building. By effectively sealing these penetrations, the spread of fire is contained within defined compartments, minimising damage and providing occupants more time to evacuate safely.
