Pressure Curtain Wall PW2500

The Zero•Net PW2500 pressure curtain wall system takes traditional curtain wall design and incorporates our FortMax™ patented thermal barrier to provide industry-leading performance. By combining this system with standard 1″ double IGUs, designers can achieve U-values that traditional framing systems can only obtain with expensive triple pane IGUs.

  • 2 ½” profile available with various back member depths
  • glazing options: 1” to 13/4” IGU
  • FortMax™ patented thermal barrier
  • available in any combination of captured or structurally silicone glazed
  • screw spline assembly allows for delivery options of:
    • factory-fabricated and glazed
    • pre-assembled for field glazing
    • knocked down (KD) for field assembly and glazing
