THERM+ S-I/FS-I Steel Facades

The THERM+ S-I and FS-I steel façade systems offer a robust mullion-transom curtain wall solution that merges traditional set-on-top construction with modern screw channel integration. With THERM+ FS-I, the pressure profile of the glass façade connects directly to the steel substructure—no welding required—thanks to the integrated screw channel. THERM+ S-I enables the use of standard steel profiles while ensuring optimal corrosion protection, making both systems ideal for durable, flexible, and efficient façade design.
