When a client asks whether single or double glazing is better, we normally look at the floor plan before giving an answer.
The reason is simple: a meeting room does not have the same requirements as an open workspace.
In many office projects, demountable glass partition systems can use single and double glazing in different areas, depending on how each room will be used.
What is the practical difference?
Single glazing uses one layer of glass and normally has a slimmer, simpler structure. It works well where the main goal is to divide the space while keeping the office bright and open.
Double glazing uses two layers of glass and a deeper partition system. It is more commonly considered for rooms where privacy, acoustic control or integrated blinds are important.
But the extra layer of glass is only part of the difference. The frame, seals, doors and other components also affect the finished result.
| Office area | What we would usually consider |
|---|---|
| Open workspace | Single glazing |
| Corridor | Single glazing |
| Showroom / display area | Single glazing |
| General office | Depends on privacy needs |
| Meeting room | Usually double glazing |
| Executive office | Usually double glazing |
| Finance / confidential room | Double glazing |
This is not a fixed rule. It is simply a useful starting point when reviewing a layout.
Where single glazing usually works well
For open offices, corridors and display areas, single glazing is often enough.
These spaces normally need separation without losing daylight or visual connection. In that situation, using a deeper double-glazed system may add cost without adding much practical value.
Single glazing also works well when the design calls for a slimmer, more minimal frameless glass partition.
Choosing single glazing does not mean choosing a “low-end” system. It simply means the specification matches the way the space will be used.
Where we normally look at double glazing
Meeting rooms are one of the most common examples.
People usually expect a meeting room to feel more private than the surrounding office, so double glazing may make more sense.
The same applies to executive offices, finance rooms or other spaces where conversations are more sensitive.
Double-glazed systems are also useful when integrated blinds are required. In some projects, the blinds are actually one of the main reasons for choosing a deeper system.
That said, we would never look at the glass alone.
A double-glazed wall with the wrong door or poor sealing details will not automatically provide the level of privacy a client expects.
Do you need double glazing everywhere?
Usually not.
We often see projects where the initial specification asks for double glazing throughout the entire office simply because it is seen as the “higher” option.
Once the layout is reviewed, a mixed solution can make more sense.
For example:
Open office and corridors — single glazing
Meeting rooms — double glazing
Executive offices — double glazing
Display areas — single glazing
This keeps the higher-specification system where it is actually useful and avoids over-specifying areas that do not need it.
It can also help keep the overall project budget under control.
If cost is part of the decision, our office glass partition cost guide explains how glazing, doors, wall height and finishes affect the quotation.
What else should be decided at the same time?
The glazing choice should normally be confirmed together with:
- door type;
- glass thickness and glass type;
- blinds;
- wiring requirements;
- frame finish;
- partition height.
For example, some 90 mm and 100 mm systems are better suited to offices that need blinds, wiring or a deeper frame structure, while a slimmer system may be more appropriate where transparency and a clean appearance are the priority.
This is why a floor plan is usually more useful to us than simply being told, “I need single glazing” or “I need double glazing.”
Not sure which one to use?
Send us your floor plan and tell us how the rooms will be used.
We can review the layout area by area and recommend where single glazing is sufficient and where double glazing would be more appropriate.
