Window Glazing Bars

Glazing bars are considered a traditional and historical style element. When paired with modern aluminium windows, the result is a unique window design. Modern buildings can enjoy a more distinct character with alu lattice windows. In the windows24.com configurator, you can choose between three different glazing bar systems: The Viennese, the Helima and Sash. While the Viennese glazing bar only rests on the glass pane, the Helima glazing bar is inserted between the glass surfaces.

The Different Types of Glazing Bars

UPVC glazing barsInexpensive, available in all RAL colours, very easy to care forDon't go so well visually with wood windows; not so good insulating characteristics

The choice of material also depends on the nature of the existing windows. A wooden bar, for example, looks less attractive on a plastic window than on a wooden window.
