Where do the muntin bars on the window work?

Muntin bars, ie strips that divide large areas of glass into parts, are a traditional and common addition to windows. However, they do not fit all types of buildings and windows. We advise when it is best to consider the installation of this decorative element?

The great return of the muntin bars

Traditionally, muntins, also known as slats, were used hundreds of years ago in wooden frames. They combined smaller lenses into one larger whole. Therefore, they fulfilled the structural function of the window.

But along with the growing interest in cheaper windows and modern PVC solutions, their popularity gradually declined. Instead of panes divided into smaller parts, preference was given to large glazing without bars. So for some time, investors have resigned from using it.

However, fashion is changing and what was once unpopular often starts to regain favor over time. This also happened with the muntin bars, which were again widely used in single-family homes, although more often they only have a decorative function. In some styles, they have even become an inevitable decorative accessory.

The muntin bars are available in different widths. They can be installed straight, diagonal and even curved. Everything depends on how they visually harmonize with the rest of the building.


Traditional white windows can visually benefit from the addition of bars – they look especially good when contrasted with the dark facade of the building.

What architectural styles do the muntin bars fit in?

The muntin bars are currently mainly a design accessory and less and less often a structural one, so when deciding to use them, the aesthetics of the entire building and its interior should be taken into account.

The muntin bars do not suit every architectural style. However, there are some where architects often and like to use them. First of all, they are perfect for historic or stylized buildings, for example in downtown tenements, where they go perfectly with wooden or PVC windows that imitate wooden joinery, such as Wood Look.

The muntin bars can be used not only in historic tenements. Also buildings that are typically rural or refer to the country style will benefit aesthetically from their mounting. The same goes for villas styled as noble country houses.

There is a place for muntin bars, not just in old buildings or investments for such stylized ones. At new ones houses in a classic style can visually benefit from such an addition without any problems provided that such windows fit the whole body of the building and its style.

The bars in the windows can significantly affect the visual reception of the room, so it is important that the interior design fits well with them. Therefore houses and apartments decorated in a rustic or industrial style can benefit from such a decorative addition for windows. The muntin bars also fit perfectly into loft apartments.

When not to place coin bars?

The muntin bars don’t work well in modernist and minimalist buildings. For example, all kinds of office buildings, production halls, modern museums and other utility facilities would rather do without this addition.

Their utility is similar in single-family homes. Where the architects opted for a minimalistic shape and large glazingyou should rather avoid splitting the windows with rods.

If we want high light transmittance and irradiance of the room, we should also refrain from installing muntin rods. Slightly, yet noticeable, they restrict the access of sunlight and affect indoor lighting.

What window colors do the muntin bars correspond to?

Finally, it is worth considering the color of windows with muntin bars. This addition fits windows that mainly refer to the classic and country style, which is why the muntin bars they will look good in wood or PVC windows with wood veneers. The choice of woody colors is very rich, so you will certainly be able to choose to match it with the rest of the building.

Traditional white windows can also benefit visually by adding rosettes to them. They look especially good when they contrast with the dark facade of the building.

In minimalist and modernist styles, veneers are popular, whose task is to imitate the aesthetics of metal structures. Matching muntins with such windows can be an extremely difficult task, so it’s probably better to give them up then.

If we want to have window frames in our house, let’s consider the general style of the building in which we want to install them. If it turns out that the muntins will match it, they will surely enrich the visual effect and make the whole look unique.
