Continuous rooflight flaps

Our best-selling continuous rooflight flaps for SHEV and ventilation


Our continuous rooflight full flaps provide three-fold benefits: very good room and space illumination with natural daylight; the possibility of electrically or pneumatically actuated aerationand ventilation for a healthy room climate; and utilisation as a natural smoke extraction system (NSHEV) in the course of preventive fire protection in combination with the corresponding openerfitting.
