Natural Ventilation

Our Natural Smoke Venting Solutions provide a reliable and cost-effective means to meeting the requirements of Approved Document B. We understand the correct fire rating required of every component to maintain the necessary compartmentation within the building, and that knowledge is underpinned by our ongoing research and development commitment.

How Do Natural Smoke Ventilation Systems Work?

Natural Smoke Venting Systems create a natural airflow that purges smoke from a building, clearing areas to ensure a safe means of escape and provide greater visibility and access for firefighters.

Natural Smoke Venting Systems can be designed based around windows, vents, automatic opening vents (AOVs) or, where it is not possible to vent through an external wall, a vertical smoke shaft. In the event of a fire, smoke detectors will activate the system and natural airflow dynamics will be used to remove the smoke as quickly and efficiently as possible.

What is included in Natural Smoke Ventilation?

• Automatic Opening Vent (AOV) - A mechanically operated vent that is linked to the fire detection system and opens in the event of a fire. 
• Windows - Windows are commonly used to provide natural smoke ventilation. Actuators can be used to automatically open the window in response to smoke.
• Vertical Smoke Shaft - Where vents or suitable windows on exterior walls cannot be achieved, a smoke shaft can be used to provide ventilation.
