Tubelite’s newest thermally broken curtain wall product has been designed to meet or exceed today’s stringent energy codes. The 400TU Series 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. 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 curtain wall framing product that the industry has to offer.
