Maximising daylight with minimal sight lines. The outer frame of the WICLINE 70SG window blends seamlessly into the mullion and transom profiles of the curtain wall, with only the glazing of the opening sash visible from the outside, blurring the boundaries between fixed glazing and opening elements. Specially designed mullion and transom profiles for WICTEC 50 system have been created to facilitate this integration, allowing opening leaves to be combined with a conventional curtain wall.
