Room Integrity Testing for Fire Suppression Systems
Need room integrity testing for a fire suppression system?
Air Tightness Solutions provides room integrity testing for contractors, fire suppression specialists and commercial projects across the UK.
We help project teams complete required testing efficiently, avoid delays to commissioning programmes and provide clear reporting following the completed test.
Whether you are working on a data centre, server room, archive facility, plant room or specialist protected environment, we can help arrange testing at the right stage of the project.
What is room integrity testing?
Room integrity testing, sometimes referred to as enclosure integrity testing, assesses how effectively a protected room can retain fire suppression gas following system discharge.
The test helps determine whether the room enclosure has been sealed sufficiently to maintain the required hold time for the suppression system to operate effectively.
Room integrity testing is commonly carried out on spaces protected by gaseous fire suppression systems, including:
- Server rooms
- Data centres
- Electrical switch rooms
- Communications rooms
- Archives and document storage
- Control rooms
- Plant rooms
- Specialist protected environments
Testing is often completed as part of the commissioning process before the suppression system becomes operational.
Why is room integrity testing important?
Gaseous fire suppression systems rely on the protected room remaining sufficiently sealed after discharge.
Excessive air leakage can reduce gas concentration levels too quickly and affect system performance.
- Testing helps confirm that:
- The enclosure can maintain the required hold time
- Leakage levels are within acceptable limits
- The suppression system can operate effectively
- The room has been sealed correctly
- Compliance requirements have been met
Identifying leakage issues before handover can help avoid delays, remedial works and retesting later in the programme.
Why choose Air Tightness Solutions?
Room integrity testing often takes place on specialist projects where timing, accuracy and communication are critical.
Clients choose Air Tightness Solutions because we provide:
- Value Engineered Advice
- Responsive & Reliable Service
- Fully Accredited
We provide compliant solutions with ATTMA accredited engineers for Air Testing.
When should room integrity testing be carried out?
Testing is typically completed once the protected room construction and sealing works have been finished.
This may include:
- Installation of doors and glazing
- Completion of service penetrations
- Installation of fire suppression systems
- Sealing of cable and pipe penetrations
- Completion of ceiling and floor interfaces
- Final sealing works
Testing too early can increase the likelihood of failed results or aborted visits if the room is not fully complete.

Common causes of room leakage
Air leakage within protected rooms is commonly caused by:
- Unsealed cable penetrations
- Poorly sealed pipe penetrations
- Door perimeter leakage
- Ceiling void leakage paths
- Raised floor leakage
- Gaps around ductwork
- Incomplete sealing works
Identifying these issues early can help reduce delays and remedial works later in the project.
