Featuring ultra-slim 30 mm sightlines that sit flush with the glass, both SF60 and SF80 eliminate bulky frames and reinforcing profiles that often obstruct views—making them perfect for creating floor-to-ceiling wall-of-glass aesthetics.

These systems support colossal panels—up to 6 m wide and 4 m tall—each capable of handling loads up to 800 kg. Entire sets can stretch across impressive spans, offering seamless indoor-outdoor accessibility.

Designed with modern building standards in mind, the double-glazed SF60 folder achieves system-wide U-values from just 1.1 W/m²K, while the triple-glazed SF80 delivers ultra-low values of 0.8 W/m²K—meeting Passivhaus-level requirements across the whole installation, not just the visible frame.

Unlike many bonded-frame systems where glass cannot be replaced independently, these doors are dry-glazed—held securely by internal glazing beads. This intelligent design ensures glass panels can be swapped quickly and cost-effectively, future-proofing your installation.
