Alumaster also offers specialized solutions that increase the comfort and functionality of glass doors. These are elements mounted on vertical edges or in the contact area of the door leaves, which improve the tightness, acoustics, and stability of the structure. Thanks to them, the glass door system becomes complete – it protects not only from below, but also vertically and at the point of contact between the door leaves.
