YCW 750 XT SSG yields best-in-class thermal performance and exceeds not only current codes, but also exceeds the most stringent green building codes and standards in the market today. The YCW 750 XT SSG yields the same best-in-class thermal performance as the YCW 750 XT system and exceeds not only current codes, but also exceeds the most stringent green building codes and standards in the market today. This vertical SSG system has captured 2-1/2” sightlined horizontals utilizing MegaTherm® technology with structural polyamide struts that accommodate standard 1” glazing units. To ensure long-term structural integrity, the dead load of the insulating glass rests on integrated structural supports, diverting this load away from the thermal barriers.
