Today, it is impossible to imagine our landscape without high-rise buildings. Increasing urbanisation in emerging regions is resulting in a growing demand for high-rise buildings. It goes without saying that window vents used in high-rise buildings must score well in terms of wind resistance, water tightness and acoustics. The higher the building, the more wind influence the building has to endure. This is precisely why DUCO has developed an attractive solution that responds perfectly to these requirements.
