System Overview
Natural ventilation systems use openable windows, rooflights, and louvres to move fresh air through buildings without mechanical assistance: reducing energy consumption, improving air quality, and doubling as automatic opening vents for smoke control. Vent Trade supplies chain, linear, and rack actuators from UCS, Topp, and Mingardi, along with thermostatic controllers, certified AOV roof vents, and smoke exhaust louvres, all held in stock for next-day delivery.
