What is the standard thickness of window glass

What is the thickness of window glass?

Thickness of glass panes with single glazing

In the case of windows with single glazing, as was customary in the past, the greatest fluctuation range can be found in the thickness of the glass panes.

Such windows can have glass panes between 2 mm and 51 mm thick. The high fluctuation range is explained, among other things, by the fact that the pane alone has to provide the entire load-bearing capacity.

The larger the glass surface, the more resilient the pane has to be. In the case of windows with single glazing, the thickness of the pane increases with the size of the window. The larger pane thickness also leads to better sound insulation, but also to a higher weight of the window.

Thickness of laminated glass

In the case of laminated glass (VSG glass), the thickness can be up to 65 mm. This is due to the fact that laminated glass usually consists of two panes of glass (possibly more) that are firmly connected to one another by a laminated plastic film. Very thick laminated glass with a very resistant film is also called bulletproof glass.

Thickness of double glazed windows

Double-glazed windows are usually between 22 and 42 mm thick.

They consist of two separate panes that are firmly and airtightly connected to each other at the edge of the pane. The filling between the panes usually consists of argon, a noble gas, and other gases and gas mixtures in the case of higher-quality soundproof windows.

The distance between the panes is essential for the physical properties of the window, for its heat and sound insulation, as well as the edge seal of the panes and its construction.

Triple insulating glass

Triple-glazed windows usually have pane thicknesses of 27 or 32 mm, but there are different values ​​for many windows.

In addition to the glass thickness, many other factors play a role in the properties of glazing. The thickness of the glass is therefore of minor importance when buying.
