Curtainwall Infinity System
The SteelBuilt Curtainwall Infinity™ System can use as a back mullion almost any type of custom steel member, allowing architects and designers to use larger areas of glass, smaller frame profiles and greater free spans. The design flexibility allows curtain walls to be incorporated into a nearly limitless range of building types, designs, and performance requirements.
