They can be hidden or visible depending on the architectural concept. The dampers work in the same way as the dampers in a frame structure with diagonal bracings but here two panels are used instead of the diagonal bracings.
The panels including dampers are prefabricated which means that they can be installed quickly into buildings. This is
especially an advantage when retrofitting as the panels can be installed quickly without much disturbance of the daily
operations of a building.
The panel damper can be made to fit typical openings in the building. And they can be designed for any capacity.
