- The redesigned Rota ventilation system offers a maximum of 80cm squared per linear meter when fully opened which provides increased levels of ventilations over traditional rooflight vents
- The system now directs air flow upward which reduces the risk of downdraughts and condensation forming
- External vent openings are fully protected to reduce risk of moisture and roof grit entering the interior space
- For the end-user the vent is actuated by a continuous T section which allows the unit to be easily opened and closed to a desired aperture
- Vent can be opened fully or 50% - which means that ventilation areas can be controlled
- Ventilation system fully drained – reducing the risk of water ingress.
