Tubelite’s 400SS SG Series Screw Spine thermally broken curtainwall product has been designed to reduce fabrication and installation labor while meeting or exceeding today’s stringent energy codes. The 400SS SG has a 2-1/2″ sight line with system depth of 7-1/2”. This screw spline system has been designed with several options that allow for pre-glazing in the shop, unitized or stick fabricated for field glazing flexibility.

Dependable Performance

The thermal isolator and thick gasketing provide excellent U-Factors and CRF when using high-performance insulated glass. Glass is positioned to the system exterior which provides enhanced resistance to rainwater. 11 anodized finishes and 19 standard paint colors are available on this framing system to complement any project with warranted protection, as well as street appeal. The 400SS also accepts Tubelite’s operable windows, Therml=Block® Doors, and Maxblock® Sunshades.

400SS low- and mid-rise is recommended for use on medium- and low-rise applications. The 1/2” min. bite (see details as bit varies with application) securely grips insulated glass or panels of 1″ thickness. An improved horizontal member allows for expansion/contraction clearances which minimizes splice requirements.

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