A partition system is only as flexible as its junctions. The M1-M2-M3 range publishes the full vocabulary: start and end modules in glass or panel, intermediate modules, a fixed ninety-degree corner, and junctions at two, three and four ways — the four-way resolved with a circular profile that lets four walls meet without a visible mess. Add the wood-to-glass continuity module and the technical module with sockets, and a floor can be drawn freely.

Structurally, the system is extruded aluminium 1.5 mm thick with airtight gaskets, heights from 2100 to 3340 mm, and soft-body impact testing at 50, 3, 1 and 0.5 kg to UNI 10880. Acoustic laminates take the system from Rw 33 to 42 dB depending on profile and glass.

Send the drawing before the purchase order: the technical office at Quadrifoglio validates the junctions, and what returns is a module list you can price line by line.

FAQ

Which junction modules exist?
Start and end in glass or panel, intermediate, fixed ninety-degree corner, and two, three and four-way junctions — the four-way using a circular profile.
Can wood and glass meet in one run?
Yes: a dedicated wood-to-glass continuity module handles the transition within the same wall.
Where does the wiring go?
Into the technical module with sockets, which is part of the standard module list rather than an improvisation on site.
What impact testing is declared?
Soft-body impact at 50, 3, 1 and 0.5 kg, to UNI 10880:2000 clauses 5.1 to 5.4.
Can the wall stand without fixing to the ceiling?
A self-supporting version exists with a 100 × 30 mm top frame; corners and joints must then be structural aluminium, and the layout is reviewed by the technical office first.

How to turn an open floor into rooms without building walls

Five moves from an empty plate to a working layout, using modules instead of masonry.

Draw the circulation first
Corridors decide where junctions land, and junctions decide the module list.
Put the noisy rooms together
Grouping them means fewer high-performance runs and a cheaper wall.
Mark the four-way crossings
They are the most expensive nodes and the ones worth reducing.
Locate power before glazing
The technical module has to sit where the desks will be, not where there is room left.
Send the layout for verification
La Mercanti passes the drawing to Quadrifoglio's technical office before the order is placed.
