The SF25 slide, turn and stack system offers clients a clear, unobstructed, panoramic view.
These SF25 Frameless Glass Stacking Doors are commonly used as patio doors to create flexible, modern and practical outdoor spaces such as balconies, terraces, and outdoor restaurant seating areas; but are also used for indoor segmentation in living and working spaces.
The first panel on the door acts as a single, independent access point that can be opened and closed independently of the others.
When opened fully, each individual panel slides independently across the same side of the track to allow for a wider opening. These panels can additionally slide from a 90-degree angle to a 180-degree angle, allowing for openings on a curved radius.
