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.

Descriptive memo

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.

Safety: toughened and laminated glass

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.

Acoustics: separating sound while staying transparent

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.

A dry, modular system

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.

Systems architecture

Why it works

Transparent to light, opaque to sound
glasslight: passes throughnoisemuch quieterunsealed joint: sound leaksmass blocks the sound; the weak point is the perimeter

Glass 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.

Longer bar = more sound stopped. A double pane with a cavity and acoustic interlayers reaches office-grade privacy while keeping the wall transparent.

Head and base connection

Top and bottom the pane runs in a «U» profile; a tolerance gap above the glass lets the structure deflect without loading it, while continuous gaskets in the profiles seal the joint to sound and hold the pane.

Vertical pane-to-pane joint

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.

Recurring defects

Diagnostics · site
Acustica
Sound leaks at joints and connections
CauseContinuous gaskets missing at the head, base or between panes: the glass insulates but the sound passes through the perimeter gaps, undoing the performance.
PreventionContinuous gaskets, sealed joints, acoustic-break profiles, attention to head and base junctions.
Meccanica
Breakage and cracking of the glass
CauseImpact, point loads on the edge, out-of-square frames or stress from a too-tight fit crack or break the pane, sometimes spontaneously (NiS inclusions in toughened glass).
PreventionSafety glass to size and risk, tolerance gaps, no edge contact, heat-soak test for toughened glass.
Termo-igrometrica
Condensation between the panes (double glazing)
CauseIn a double system, a failed edge seal lets humid air in: it condenses in the cavity and fogs the glass, which can no longer be cleaned.
PreventionQuality sealed units, drained/ventilated profiles where applicable, protection of the edge seal.
Adesione
Detachment and slipping of the gaskets
CauseGaskets that shrink, harden or were badly fitted come loose and slip out: the pane rattles and the acoustic and dust seal is lost.
PreventionQuality gaskets correctly sized, continuous runs, periodic inspection and replacement.
