Sophisticated design for challenging technical requirements

As approved SHEV unit, Draco-vent combination wings were designed for ridge-shaped rooflights, like Skyline and the daylight system Shedline. Draco-vent is available as glass combination wing section |1| or glass single-wing section |2|.

Also with pyramids and other glass building structures Draco-vent fulfills the technical requirements for an optimised ventilation and fire protection.

Draco-vent successfully provides an optimised solution for the requirement of a reliable rain-proof-ventilation and creating the largest possible smoke extraction area.

Variable ventilation and rain-proof-ventilation technology

Conventional glass wing sections with only an upward opening ventilation function can be used as a SHEV unit and for daily ventilation. However when used for ventilation there is the risk of rain entering while the flap is in closing mode.

Draco-vent successfully provides an optimised solution to ensure reliable rain-proof-ventilation. Daily 'comfort ventilation' can take place by opening the flap at the bottom. At the same time, the opener cross-beam is designed in such a way that, in the event of a fire, it can open at the top effectively and create the largest possible smoke extraction area.

Control technology

Control technology

Intelligent control technology integrated in the  building automation system. Drive technologies are available as pnestumatic and electric solution.


Fall and fall-through protection

Continuous rooflights and light domes without structural features to render them permanently fall-through proof must include suitable covers or suspended structures which prevent individuals from falling through. INDU LIGHT protective systems are available for continuous rooflights and light domes and can be retrofitted onto all current INDU LIGHT products.
