Abstract (en)
[origin: WO2021176288A1] The present invention relates to a system (1) for shielding sun rays comprising: at least a first glass (2); at least a second PVD coating-free glass (3) and associated to the first glass (2) by means of a supporting frame (5) for forming a gap (51); a sun ray protection device (4) inserted in the gap (51), said sun ray protection device (4) defining: - a plurality of transparent areas (41) for letting sun rays pass through, such plurality of transparent areas (41) enabling sun rays to pass with a certain incidence angle while sun rays having other incidence angles are not able to pass through said plurality of transparent areas (41); - a plurality of blind areas (42) configured not to let sun rays pass, such blind areas (42) identifying a first surface (421) facing the second PVD coating-free glass (3) and a second surface (422) opposite to the first surface (421); such plurality of blind areas (42) have a reflection in the visible (ρv) lower than 50% and have an reflection index of sun rays (ρe) higher than the reflection index in the visible (ρv).
