400TU High Performance Thermal Curtainwall

Providing superior thermal performance that meets or exceeds today’s stringent energy codes.

Tubelite’s highest thermally broken curtainwall product has been designed to meet or exceed today’s stringent energy codes. The 400TU Series Curtainwall has a 2-1/2″ face, and offers screw-spline or shear clip assembly. The pressure bar system can be stick fabricated, or assembled into “ladders” at your shop for field glazing.

Beauty and Performance

The dual thermal strut decreases U-Factors and increases CRF significantly over many current thermal barrier systems. Glass is positioned to the system exterior for enhanced resistance to rainwater. The 400TU also accepts accessories like Tubelite Operable Windows, Therml=Block® Doors, aLuminate® Light Shelves and Maxblock® Sunshades.

The 1/2” bite securely grips insulating glass or panels of 1″ or 1-3/4″ thickness. Verticals can be steel-reinforced for high performance against strong windloads.

Thorough testing by an independent laboratory ensures that 400TU is the highest quality curtainwall framing product that the industry has to offer.

System Features:

  • Aluminum, Polyamide and Thermal Pressure Plate available.
  • Dual and Triple Glazed options for insulated glass.
  • Vertical members can also be used as horizontals (for shear clip assembly).
  • Stick fabricated with shear clip or screw spline construction.
  • Options for Captured and SSG horizontals and verticals.
  • Can be used with aLuminate Light Shelves and MaxBlock Sunshades.
