System Description
Series PW251 is a 2-1/2” X 7” is a screw-spline assembled pressure wall curtain wall system can accommodate 1” insulated glass for low-rise, multi-story and monumental applications. Snap-together profiles using integral screw-spilne joinery allows for the frames to be pre-assembled in panels resulting in increased productivity and quality control. PW251 options include fully captured and two-sided silicone structural glazed and 10” deep profiles are available.
