Exterior Technologies Inc. (EXTECH) is offering two new suspension systems for its KINETICWALL moving building façade: Drop-In and Pin-Mount (Rod-Mount is also available). The Drop-In suspension system has T-shaped kinetic flappers that are inserted into a rung extrusion system. The Pin-Mount suspension system makes the flappers appear to float in front of the support rungs and side rails. Flapper shapes can be mixed to create geometric patterns and for installation at various mounting points, facilitating changes in kinetic activity.
