  • Sealing louvers for roof structures
    Patent number: 11993930
    Abstract: Louvered roof systems are provided with one or more louvers. Such louvers can be combined in an assembly that is movable between an open condition and a closed condition. In the closed condition, louvers in the assembly engage one another. In such engagement, a leg extending generally transversely from one louver may include a wing that extends generally transversely to the leg and that abuts a surface of an adjacent louver. Additionally or alternatively, in such engagement, a leg extending transversely from one louver may be received in a notch in an adjacent louver. An end cap can include a downwardly extending flange that directs liquid flow from a louver's top surface and past its bottom surface to form droplets or streams to fall from a lower part of the flange and prevent travel of the liquid flow along the bottom surface of the louver.
