Static Smoke Barrier glass D600 & DH classes

Flames are not the only danger during a fire. Smoke can also reach extreme temperatures and impede the safe evacuation of building occupants. Smoke containment screens were designed to mitigate this risk. These screens are regulated to provide stable fire resistance at a constant temperature (600 °C) or on a standardized time-temperature curve (ISO 834).

D/DH class solutions

 

Discreet Glazed Solutions with Tested Stability

These static smoke control systems are engineered for environments where both visibility and performance are critical. The use of DH class fire-rated glass ensures that the system holds its integrity even as fire intensity progresses along a realistic temperature curve. This makes it ideal for applications like atriums, corridors, lobbies, and vertical shafts where smoke migration must be controlled over time.

 

Performance

Performance

Smoke barriers tested for a constant temperature stability time (D) must maintain their integrity for a defined time at 600 °C. Barriers are classified in accordance with EN 13501-4 (Classification using data from fire resistance tests on components of smoke control systems). 

 

Normalized classes

Classes  Temperature (°C)  Time (min) 
D600 30  600  30 
D600 60  600  60 
D600 90  600  90 
D600 120  600  120 
D600 A  600  Any duration beyond 120 min 

 

 

Smoke containment screens tested according to a stability period with the standardized time-temperature curve (DH) must maintain their integrity for a defined time-temperature pair. Barriers are classified in accordance with EN 13501-4 (Classification using data from fire resistance tests on components of smoke control systems).
