A 3-chamber profile with a width of 60 mm and a series of 13-mm glazing beads is distinguished by high-quality characteristics and is affordable. A glazing bead is a structural element of a window frame used to fasten glass or double-glazed windows. It has the same characteristics as the 4-chamber profile. These types of windows are often used in commercial and industrial buildings and structures, providing energy efficiency by reducing heating and cooling costs.
