Venting rooflight solutions

Whether ventilation is needed to provide fresh air for occupants or to facilitate the escape of smoke and heat, the range of continuous polycarbonate rooflights from VELUX Commercial can help.

Choose from an array of configurations for natural ventilation, with options including single flaps, double flaps, side flaps, crossbeam flaps and full flaps. Surface fans can also be integrated into the rooflights to increase airflow.

Refurbishing industrial roofs with continuous polycarbonate rooflights

Thanks to their lightweight properties and ease of installation, continuous polycarbonate rooflights are often used for refurbishment projects, either to replace existing rooflights or as part of a wider effort to bring natural light into the building and improve ventilation. Their lightweight build up makes them ideal for roofs not originally designed to hold the weight of rooflights.

The upstands used with polycarbonate rooflights create a secure connection between the supporting structure and rooflight, helping to ensure weather tightness and thermal efficiency. Various sizes are available, and they can be finished with an optional colour coating.
