Weather Seam

Weather Seam is a weathertight  seismic expansion control system for interior and exterior walls and ceilings. An optional secondary moisture barrier is available for exterior applications. The colorable elastomeric seal  completely covers the supporting  aluminum frame creating a functional and attractive joint. Weather Seam accommodated thermal movement and multidirectional seismic movement. Wider Weather Seam joints employ multiple seals with selfcentering bars and a nylon reinforced pantograph mechanism. Seals are available in standard black, beige and gray.
