WCO can provide extract ventilation as well as allow the entry of natural daylight for most kinds of industrial and commercial buildings. WCO is predominantly a Climate Control product, as it’s top section provides maximum ventilation. WCO can also be used for emergency smoke extract ventilation, although it is not certified as a smoke ventilator. Two controllable side dampers provide day-to-day ventilation when it is raining.
* In many cases a U value of at least 3.5 W/m²/K is required to meet local Regulations. This value can be achieved or surpassed if the ventilator is installed on an upstand which protrudes above the outer membrane of the roof. Colt can advise on this.
