1. A roof or skylight window comprising a frame and an insulated glazing unit, wherein the insulated glazing unit comprises:
a first glass pane and a second glass pane each having inner surfaces opposing each other, and
a side seal arranged between the first glass pane and the second glass pane creating a sealed cavity between the first and second glass panes;
wherein the first glass pane comprises an edge surface region overlapping the side seal along at least a first part of the side seal, wherein the edge surface region is a region close- to or at a peripheral edge of the first glass pane, wherein the edge surface region comprises an enamel layer comprising pigments wherein the pigments are metal and metal oxides comprising one or more of the metals selected from the list of: Aluminum; Antimony; Bismuth; Cobalt; Copper; Chrome; Iron; Manganese; Nickel; Titanium; Vanadium; Zinc; Zirconium;
wherein the pigments reflect at least 40% of solar radiation in a near infrared wavelength range between 700-2500 nm; and
wherein the insulated glazing unit has a periphery temperature at the edge surface region, wherein the pigments reduces the periphery temperature by at least 10 degrees when the insulated glazing unit is exposed to direct solar radiation of 900W/m2.
