VELUX and RENSON have introduced Topfix VMS, a motor-operated sunscreen with special mounting feet engineered for fixed and movable VELUX Modular Skylights. It employs ZipShade technology, providing fabric tension and wind resistance up to 75 mph. The proprietary design integrates screen fabrics to which zippers are affixed and move within a side channel and guide system for smooth extension/retraction, consistent fabric tension and resistance to the elements. Topfix VMS is available in a variety of colors and blackout-shade options. It can be integrated into a building-management system.
