OVs (Opening Vents) and AOVs (Automatic Opening Vents) are required to meet the relevant Building Regulations for ventilating escape routes. The Regulations stipulate a minimum free ventilation area (normally 1.0m² or 1.5m²), and require units to open to either 90° or 140° depending on a number of factors. Ventilation areas can be achieved with a variety of square or rectangular Em-Domes and can be used in conjunction with Em-Curb upstands or T-Collar and Em-Collar adaptors.

Opening the rooflight is by means of a 24V DC electric actuator. For OVs we can provide a stand alone control panel with a comprehensive range of accessories – for AOVs our control panel can interface with the main Building Management System (BMS) or accessories. Due to the variety of BMSs that are required to satisfy the relevant authorities, we recommend that a qualified mechanical and electrical company is employed to plan and install the system.
