Window muntin bars
The muntin bars are wooden or aluminum slats that divide window sashes into an appropriate number of boxes specified by the customer. They mainly have a decorative function, although sometimes they are also structural elements of the window. In many cases, the use of muntins is indispensable – it allows to preserve the style of historic buildings, and gives newer buildings a unique character.

There is one glazing unit in the wing. Wooden slats are placed from the outside, but they do not touch the surface of the glass – they are offset from it by about 3 mm. The muntin can be attached to the sash with latches, enabling it to be removed, e.g. when cleaning windows, or with hinges enabling the frame to be opened with a muntin.
