Tests covering a broad range of criteria were carried out by the Institute of Materials Testing in Nor th-Rhine-Wes tphal ia and
those of the Institute of Industrial Aerodynamics in Aachen. This included testing the performance of the louvre windows and their structural integrity in response to fire, as well as determining the aerodynamic ventilation characteristics for units of different sizes.

The test results with different sizes, systems and four different drives enable our customers to choose from an exceptionally wide range of NSHEV`s for their required application. Naturally, the tried-and-tested qualities of our FLW louvre windows remain unchanged. With the rack and pinion mechanism only a low stroke is required to completely open the units. As a result, our units provide the maximum ventilation free area in the shortest possible time. A perfect synthesis of visual and functional features, combined with the safety qualities of a certified system.

As an additional service, we can quote you for commissioning your SmoTec louvre windows. Maintenance contracts for routine inspections of the installations are available at all times.
