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.
