The MOVA system is an innovative, modular window sill system that offers maximum flexibility and interchangeability. Thanks to a variety of mounting options with or without a screw flange, the system provides customisable variants to meet a wide range of requirements. The tested water tightness under heavy rain of up to 1,950 Pa ensures optimal protection, while the reduced plastic content contributes to environmental protection. The independent components are stress-free and can be easily mounted without permanent connections. Water is efficiently channelled away using the cascade principle, and the “Viennese installation method” allows for a detachable connection between the window sill and masonry.
