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.

Fall-Through protection

Safety is our number one priority. That is why all INDU LIGHT continuous rooflights come together with the IAP1 anchor point. This includes a stainless steel bracket which is integrated in the eave structure of the continuous rooflight and fixed to the frame head. Attached to the PPE it protects personnel from falls. Anchor point IAP1 is a tested class A1 anchor device in accordance with EN 795:1996-07/A1:2000-10 (D) und EN 795:2012-10 (D)
