As part of our ongoing commitment to performance, compliance, and safety, Safetyline Jalousie is proud to confirm that our louvre window systems — in combination with our new actuator from SE Controls — have been independently tested as a complete system to meet the performance requirements of EN 12101-2:2003 for Natural Smoke and Heat Exhaust Ventilators (NSHEVs).
This achievement reflects our broader mission to push the boundaries of what’s possible in operable window and ventilation design, ensuring our solutions perform not only in everyday conditions but also in emergency situations where reliability is critical.
Tested for Use as NSHEVs – Natural Smoke and Heat Exhaust Ventilators
Our glass louvre and actuator systems have been tested to demonstrate their suitability for use as NSHEVs — a vital component of modern building safety strategies.
Applications include:
- Smoke and heat extraction
- Make-up air in stair pressurisation systems
- Emergency ventilation of corridors and escape routes
By satisfying the relevant criteria under EN 12101-2, our systems offer a robust and compliant solution that supports occupant safety and emergency access in the event of a fire.
Natural Ventilation, Air Tightness and Safety in One System
Safetyline Jalousie systems are designed to deliver high-performance natural ventilation, air tightness, and smoke control capabilities — offering architects and consultants a single solution that meets both functional and safety requirements.
Ideal for:
- Residential apartments
- Hotels and student accommodation
- Schools and universities
- Retail and commercial buildings
When triggered, the system enables the rapid release of heat and smoke, maintaining clear escape paths for longer and supporting emergency services access.
Our NSHEV-ready systems allow for the integration of natural smoke ventilation solutions that satisfy compliance requirements without compromising architectural intent.
What Does EN 12101-2 Testing Involve?
EN 12101-2:2003 is the European standard for Natural Smoke and Heat Exhaust Ventilators (NSHEVs), defining how these systems must perform under real-world fire conditions.
Our systems were tested in accordance with Annex G, which evaluates the fire resistance of a ventilator system by exposing it to temperatures of 300°C.
Acceptance criteria (according to paragraph G.4 of the standard):
- The sample must remain closed without signs of deterioration for the first five minutes of the test
- At five minutes, the ventilator must be manually initiated into its fire (open) position
- Throughout the test, the effective throat area must not be reduced by more than 10%
This confirms that the system can withstand intense heat, respond reliably on demand, and maintain airflow critical to smoke extraction.
While not currently mandated in Australia, Safetyline Jalousie undertook this testing voluntarily to ensure our systems meet internationally recognised standards—providing future-proof compliance against potential legislative changes and peace of mind for clients that the product will perform as intended when it matters most.
Why We Go Further
At Safetyline Jalousie, we believe that performance and safety must be backed by real-world testing — not assumptions. In critical applications such as smoke control, non-compliant or underperforming systems aren’t just a risk — they can compromise the safety of occupants and responders.
That’s why we continue to test, innovate, and invest — so our clients can specify our systems with absolute confidence, knowing they’ve been developed to support performance-based design and reduce risk across every project.
