Office glass partitions: plan them right, not twice

Start with use, not with glass

Glass partitions are popular in offices because they divide space without blocking daylight. Whether a solution works day to day, however, depends less on its looks than on what happens on either side of the wall. A meeting room for confidential talks has very different needs from a project room that only needs visual separation.

Before asking for quotes, write a short description of how each planned zone will be used. It is the single most useful document for planners and suppliers, and it stops quotes from being based on different assumptions.

• What happens in the enclosed room: phone calls, meetings, focused individual work, receiving clients?
• How loud are the neighbouring areas in normal operation, such as reception, kitchenette or open-plan space?
• Where is visibility welcome and where is privacy needed, for example because of screens or HR conversations?
• Which doors, fanlights or openings are required, and do they need to be step-free?
• Is the space rented or owned, and how long should the solution last?

Plan acoustics and privacy deliberately

A common misconception is that more glass automatically makes a better office. In practice it is usually easier to reduce sources of disturbance first and only then decide how transparent each zone should be. A graded approach, where not every room is equally open, often produces a calmer office that is still bright.

Sound insulation is not just a matter of the glass. Single or double glazing, laminated glass with an acoustic interlayer and glass thickness all matter, but so do the connections to ceiling, floor and walls and the door seals. Even a high-performance pane loses much of its effect if sound travels through an open grid ceiling, a raised floor or a gap under the door. Ask which complete assembly a quoted sound insulation value refers to, not just the pane.

Privacy can be solved selectively: frosted bands at seated eye level, printed or switchable glass, or curtains. Frosted bands often do double duty as a safety feature, since large glass surfaces should be clearly marked so people notice them.

Technical essentials and regulations

Beyond acoustics and appearance, some points are non-negotiable and must be settled early. Which requirements apply in a given case depends on the building, the canton and the use.

• Safety glass: in circulation areas, toughened or laminated safety glass is generally required. The SIGAB guideline on safety with glass is a widely used benchmark in Switzerland.
• Markings: large continuous glass surfaces need clearly visible markings so nobody walks into them.
• Fire protection: if the wall sits on a fire compartment boundary or an escape route, the VKF fire protection regulations apply. Tested fire-rated glazing and doors are then required, and the authority or the building's fire safety officer must be involved.
• Escape routes and accessibility: door widths, thresholds and opening direction must fit the escape concept and, where relevant, the SIA 500 standard.
• Building services: ventilation, cooling, sprinklers, lighting and sockets must not be cut off by new rooms. An enclosed room without its own air supply quickly becomes stuffy.
• Tenancy: in rented space, alterations need the landlord's written consent. Also clarify whether the partition must be removed when you move out.

Make quotes comparable

The cost of a glass partition depends heavily on glass build-up, height, number of doors, acoustic and fire requirements and installation effort. Flat prices per square metre therefore say little. What matters more is that every quote describes the same scope.

1. Give all suppliers the same use description and the same floor plan.
2. Ask for a breakdown by glass, profiles, doors, hardware, film and installation.
3. Check whether site measurement, ceiling and floor connections, disposal and night work are included.
4. Get sound insulation values and glass types confirmed in writing, including the conditions under which they apply.
5. Clarify warranty, spare parts availability and whether elements can later be moved or reused.

The cheapest quote is only cheap if it includes the same work as the others.

Installing during operations

When an occupied office is refitted, the sequence of work often matters more than the component itself. Noise, dust and blocked routes disrupt business more than expected if they are not planned.

• Have the existing space measured precisely before glass is ordered, because panes are made to measure.
• Split installation into stages so only part of the floor is affected at any time.
• Coordinate delivery of large panes with the lift, stairwell and property management.
• Schedule noisy work such as drilling into ceiling and floor outside core hours.
• Book interfaces with electricians, ventilation and flooring in advance so no trade waits for another.

A realistic example: a fiduciary office with 25 workstations wants two meeting rooms. If the ceiling and floor work is done on a Friday afternoon and Saturday and the panes are installed the following week, day-to-day work is barely affected. Without a staged plan, the whole floor would be restricted for several days.

Frequently asked questions

A well-planned glass partition organises not only the space but also the working day. Considering use, acoustics, regulations and installation together gives you a solution without costly corrections.
