Windows with muntin bars were once the only way to build large windows. The bars provided a support function. But these days, this support is no longer required, and modern-styled lattice windows have become architectural design elements.
Muntin bars are modern and popular! They can be used to provide wonderful enhancements to façades. Fans of the country house style particularly appreciate this. In combination with appropriate furnishings, you can create dream living spaces that combine the modern and traditional.
