QUADRA
The Quadra collection by ADL expresses structural purity through the geometry of its square profiles. Characterised by a distinctive square cross section that runs along the entire framework, Quadra transforms glass panels into true architectural partitions. Its minimalist design allows the creation of movable glass walls that define space with precision while maintaining transparency and light continuity.
Available in Sliding Door and Pivot Door versions, the collection embodies balance between form and function, uniting architectural strength with refined motion. The integration of the handle within the upright rod enhances the linear continuity of the system, resulting in doors that combine technical excellence with timeless, sculptural design.

QUADRA Door Types
SLIDING DOOR
The Quadra sliding door is distinguished by its square cross section, which defines the entire perimeter of the panel. This architectural profile transforms the door into a mobile wall, dividing and connecting spaces with seamless continuity. The integrated handle within the upright rod maintains visual purity, while the sliding mechanism ensures silent, fluid movement throughout the living environment.
PIVOT DOOR
The Quadra pivot door emphasises geometric precision through its frameless movement and square-profile design. The absence of a wall jamb and the integration of the rotation hinge within the frame enhance both technical performance and visual clarity. Large panels pivot smoothly, closing gently with autonomous precision, highlighting Quadra’s architectural rigour and sculptural elegance.
