Platinum Series Hung-Slider Windows

Meant for residential as well as commercial uses, the Storm King System 4500 is a popular choice for commercial as well as institutional applications by being able to have limited ventilation possibilities for the building occupants. The design of the hardware mechanisms can be configured to limit the sash operation to tilt only, allowing safe and secure ventilation at the top, making the window safe for use on upper floors of buildings. In this mode, the mechanisms can be unlocked by maintenance or janitorial personnel for cleaning or general maintenance.  


  • Multi-chambered frame design with staggered weep system channels for efficient water drainage.

  • Pocket sill configuration for structural integrity.

  • T-mullion profile for multiple-lite configurations within a single perimeter frame.

  • High-definition finish for weather and stain resistance and ease of maintenance.

  • Available in different frame options for accessory grooves, integral nailing and/or stucco finish.

  • Colors: white, beige, or clay
