Disclosed is a method for integrating at least one optical element inside an insulated glazing unit comprising at least two glass panes, where the optical element has a plurality of perforations and a non-perforated area, where the non-perforated area prevents penetration of light in a building where the insulated glazing unit is mounted, and where the perforations have a depth/width ratio that allows for passage of light with given angles of incidence, while light having other angles of incidence are unable to pass though the perforations, which provides a shading effect, and wherein the optical element is arranged between the two glass panes by means of an adhesive, and where the adhesive is substantially not present in the perforations of the optical element.
