Patent ID: 8776458

Claim:
A skylight to be integrated in a covering structure made of insulated sheets, comprising at least one top fretted transparent panel ( 20 ) having a substantially flat base ( 23 ), said at least one top fretted transparent panel ( 20 ) being extruded from plastic material and at least one bottom transparent alveolar panel ( 30 ) having a top surface and a bottom surface extruded from plastic material, firmly integrally joined together by interposing a layer of adhesive material ( 40 ) wherein said layer of adhesive material ( 40 ) is prearranged on a bottom surface of said at least one top fretted transparent panel ( 20 ) and on the top surface of said at least one bottom transparent alveolar panel ( 30 ) facing the at least one top fretted transparent panel ( 20 ), said at least one bottom transparent alveolar panel ( 30 ) comprising a closed cell multi-alveolar panel, said at least one bottom transparent alveolar panel ( 30 ) comprising at opposite ends, in the direction of the width, respectively a recessed seat ( 32 ) and a projecting edge ( 33 ), for lateral coupling with an adjacent at least one bottom transparent alveolar panel ( 30 ), said at least one top fretted transparent panel ( 20 ) comprising a portion projecting transversely beyond said at least one bottom transparent alveolar panel ( 30 ) for transverse coupling by superimposing with an adjacent at least one top fretted transparent panel ( 20 ) said at least one bottom transparent alveolar panel ( 30 ) comprising knurling on the top surface facing said at least one top fretted transparent panel ( 20 ), said knurling comprising a succession of triangular-shaped cusps havine tips ( 34 ), said layer of adhesive material ( 40 ) being discontinuous and arranged between the tips of said triangular-shaped cusps ( 34 ) of said knurling and said substantially flat base ( 23 ) of said at least one top fretted transparent panel.
