400T Thermal Curtainwall

Tubelite’s newest thermally broken curtainwall product has been designed to meet or exceed today’s stringent energy codes. The 400T Series has a 2-1/2” face, with system depths from 6-1/4” to 10-1/4” and optional polyamide pressure plates. The shear block system can be stick fabricated for field glazing.

Beauty and Performance

The expanded thermal break and thicker gasketing improves U-Factors and CRF over Tubelite’s current 400CW thermal barrier system when using the same size and type of insulated glass. Glass is positioned to the system exterior for enhanced resistance to rainwater. Seven anodized finishes and 20 standard paint colors are available on this framing system to complement any project with warranteed protection, as well as street appeal. The 400T also accepts Tubelite’s Operable Windows, Therml=Block® Doors, Maxblock® Sunshades and aLuminate® light shelves.

400T Series Curtainwall is recommended for use on medium- and low-rise applications. The 1/2” bite securely grips insulated glass or panels of 1” thickness. Infill thicknesses from 1/8” to 1-5/16” also can be accommodated. Verticals can be steel-reinforced for high performance against strong windloads. An improved horizontal member allows for expansion/contraction clearances to minimize splice requirements.

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