Insulating glass units with internal muntin bars combine traditional aesthetics with modern functionality. They are an ideal choice for investors who appreciate elegant, classic window design while maintaining high thermal insulation and easy maintenance.
At Vitroterm-Murów, we offer insulating glass units with decorative internal muntin bars placed inside the glass unit—between the panes. This solution provides the appearance of traditional window division without affecting the window’s structural integrity or thermal insulation performance.
The muntin bars we use are precisely bent and symmetrically arranged, ensuring a high-quality finish and perfect alignment with the window frame geometry. We offer them in widths of 8, 18, 26, and 45 mm, in a wide range of colors—including wood-effect designs and the full RAL palette.
Our product range includes TermoProfi Viennese muntin bars – a new-generation solution for window and façade manufacturers who expect not only durability but also top-tier thermal performance. Made from a composite material with extremely low thermal conductivity, they eliminate thermal bridges and significantly improve the insulation of the entire glass unit.
The use of glass fibers ensures high structural rigidity, providing stability even in large-format glazing. The TermoProfi system also includes a full range of compatible installation accessories, enabling fast and repeatable prefabrication of muntin-bar constructions.
