Bifolding doors create a striking focal point, especially when paired with the premium finish PVD Black (Physical Vapor Deposition), which provides a durable surface that resists wear and tarnishing. The Weatherfold 4s 50 & 100 systems are available in three finishes, including PVD Black and seamlessly integrate with Brio’s 612 pleated insect screen and the 286 dual point lock, which secures both top and bottom of panels with a single lever turn. Weatherfold 4s 50 & 100 systems are ideal for homes seeking seamless indoor-outdoor connectivity, and commercial applications requiring flexible spaces.
For heavier and larger panels, use Weatherfold 4s 150 which can cover openings up to 19m wide and 4m high.
