Atrium Smoke Extract System

SK Ventilio designs advanced smoke extract systems for atria, sky-lit spaces, and large open-plan interiors where conventional smoke zoning is impractical. Our atrium smoke extract designs maintain a tenable smoke-free layer at low level, allowing safe occupant evacuation while providing firefighters with clear access and visibility.

We use deterministic and probabilistic fire engineering methods — including CFD (Computational Fluid Dynamics) simulations — to verify system performance under realistic fire scenarios, ensuring full compliance with BS 7346, BS EN 12101, and fire authority requirements.
