Vario Continuous Rooflights are ideal for large-area glazing of industrial and commercial flat roofs and sloping roofs. They enable spaces to be filled with diffused natural light and can also be used for both comfort ventilation and smoke and heat exhaust ventilation (SHEV).


With a high-quality and robust construction, Vario rooflights feature aluminium frames and polycarbonate multi-wall sheets. They are made-to-measure and pre-fabricated at our factory, and a wide choice of configuration options and accessories are available. The high degree of pre-assembly and easy installation saves project time and costs.
