Internal glass partition
An internal dividing wall made of safety-glass panes held by perimeter profiles in aluminium or steel. It divides spaces without closing them to light: it separates for acoustics and use while keeping transparency and a sense of openness. It is a dry, modular and reconfigurable system, typical of offices and commercial spaces, in which the glass acts as the diaphragm and the profiles and gaskets govern acoustic sealing and safety.

An internal dividing wall made of safety-glass panes held by perimeter profiles in aluminium or steel. It divides spaces without closing them to light: it separates for acoustics and use while keeping transparency and a sense of openness. It is a dry, modular and reconfigurable system, typical of offices and commercial spaces, in which the glass acts as the diaphragm and the profiles and gaskets govern acoustic sealing and safety.
The glass partition is a non-load-bearing internal divider in which the «wall» is a glass pane. It is made to separate without darkening: it brings natural light deep into the plan, gives a sense of openness and order, and can be taken apart and reassembled when spaces change. The glass is safety glass — toughened or laminated — and runs inside perimeter profiles that hold it and govern its joints.
A human-height wall must break without injuring. Toughened glass, if it fails, shatters into small blunt granules; laminated glass (two panes with a plastic interlayer) holds the fragments like a windscreen and keeps the pane in place even when broken. Partitions use these safety glasses, chosen by thickness and type according to size and impact risk.
Glass insulates from noise by mass, like any wall: the thicker it is (or laminated with acoustic interlayers), the more it attenuates. But the weak point is the perimeter: if the joints between panes and the connections to ceiling and floor are not sealed with continuous gaskets, the sound passes there. For high acoustic performance, double panes with a cavity, acoustic-break profiles and careful gaskets are used.
Everything is dry-assembled: the floor, ceiling and stile profiles are fixed to the structure, the panes are inserted and locked with glazing beads and gaskets, the doors (hinged or sliding) integrate into the modules. No water, no drying time, and easy reconfiguration. Care goes to the flatness of the connections, the tolerances (glass does not forgive being out of square) and the structural and seismic joints, which the system must follow without loading the panes.
Why it works
Transparent to light, opaque to soundGlass lets the light through but not the sound: to cross it, the sound wave must set its mass vibrating, and the thicker the pane (or double, or laminated with acoustic interlayers) the harder that is. The weak point is not the pane but its perimeter: an unsealed gap at the connections or between panels lets the noise through almost undisturbed. This is why the acoustics of a glass wall hinge on continuous gaskets and, for high performance, on a double pane with a cavity.

Between adjacent panes the vertical joint is closed with a continuous seal (silicone or a slim profile with gaskets): it keeps the line clean and, above all, seals the acoustic weak point so sound does not sneak between the panels.
