Compliant fire sealing and fire stopping solutions to prevent the spread of fire and smoke through penetrations and building systems.
Fire sealing and fire stopping are critical components of passive fire protection, designed to prevent the spread of fire and smoke through openings, joints and service penetrations in a building.
These systems are installed wherever services such as electrical, plumbing and mechanical systems pass through fire rated walls and floors. Without proper sealing, these penetrations can compromise fire compartments and allow fire and smoke to spread rapidly throughout a building.
Bowsers provides professional fire sealing and fire stopping services across commercial, industrial and infrastructure projects, ensuring all installations meet Australian standards and compliance requirements.
All works are carried out with careful attention to system selection, correct installation methods and long term performance.
Fire sealing and fire stopping must be installed in accordance with Australian Standards and the National Construction Code to ensure building compliance and occupant safety.
Incorrect or incomplete fire stopping is one of the most common compliance issues in buildings and can significantly impact fire safety performance.
Bowsers ensures all fire stopping systems are installed to meet required Fire Resistance Levels and compliance standards. We provide inspection reports, compliance audits and support with fire safety statements where required.
Our team works closely with builders, consultants and certifiers to ensure all systems are correctly installed and documented.
Fire sealing and fire stopping systems are required in most building types where services penetrate fire rated elements.
Common applications include:
