Fully Tested Impact Resistant Curtain
Wall Systems to Accommodate 9/16″ Laminated Glass
Series PW256 is a 2-1/2” x 6-9/16” impact-resistant screw-spline assembled curtain wall system can accommodate 9/16” laminated glass designed for wind-borne debris applications. PW256 impact-resistant curtain wall is fully tested in accordance with ASTM and Florida Building Code standards for large missile impact and is approved for use in south Florida’s High Velocity Hurricane Zone and coastal areas considered wind-borne debris regions. PW256 options include fully captured and two-sided silicone structural glazed applications.
