According to the Polish dictionary definition by Wladysław Kopaliński:
muntin archit. a bar, strip separating the window opening into glass filled partitions. German etymology Sprosse – bar; rung.
Muntins are divided into:
- Inter-pane (fixed)
- Vienna-style (glued)
Structural muntins are the most classic form of muntins, dating back to the same time as windows. They are installed in wood windows, strengthening their structure and enhancing the look of classic wood windows, particularly if they are installed in historic buildings or modern residential buildings with a traditional architectural style. We offer muntins in two widths – 6 cm and 8 cm.

These are muntins installed by the manufacturer of insulated glass inside the glass chamber. This is currently the least often chosen form for division of glass panes. Inter-pane muntins are manufactured in thicknesses of 8 mm, 18 mm, 26 mm and 45 mm. These muntins are available in different colours and in an imitation wood variant. Their main advantage is that they does not require maintenance and cause no problems during cleaning, as they are placed inside the window. The downside is that it is visible that the muntins are made of a material other than wood. Furthermore, they cannot be removed once windows are in use, as this would entail exchanging the whole glass pane set, which is costly.
They are a compromise between structural and inter-pane muntins. Inside the glazing is the so-called “blind muntin”, onto which 30 mm wooden slats are glued on from the outside on both sides using a special tape – Vienna-style muntins. The window is therefore divided into small panes from the outside. This solution creates problems when cleaning windows, but Vienna-style muntins look beautiful and natural.

Suspended muntins are used only in wood windows. Their biggest advantage is the possibility of easy disassembly for cleaning. They are installed on small hinges and hooks that make it easy to open them. They are installed on the outside of the window. Due to the less laborious nature of their manufacture, they are the cheapest option among wooden muntins. If one changes one’s mind or fashions change, they can always be removed and the appearance of the window changed.

The price of mullions is calculated as the number of panes that the window will be divided into times the fixed price of a muntin.
