Sealing Penetrations and Voids to Prevent Fire and Smoke Spread

Effective fire stopping and passive fire protection is critical to maintaining the integrity of your building’s fire compartments. Even small gaps around service penetrations, voids, or junctions can allow fire and smoke to spread rapidly.

At Crown, we provide fully compliant fire stopping solutions that restore compartmentation and safeguard both lives and property.


Our Fire Stopping Services Include:

  • Sealing around pipework, cables, and duct penetrations to prevent fire and smoke migration
  • Fire batt and mastic systems for larger openings
  • Intumescent wraps, collars, and pillows for plastic services
  • Soffit, ceiling, and riser sealing to maintain compartmentation throughout the building
  • Full photographic records and compliance certification logged in the Bolster system for traceability and audit readiness
