A load support structure supports a load on a metal panel roof. Such load support structure includes multiple closure members including opposing side rails, and optionally end closures. The rails are mounted on roof panel ribs. Cavities can be disposed inwardly of the outer perimeter of the support structure as defined by the closure members, in upper portions of the closure members. Rods may be inserted through slot-shaped openings, into the cavities. Cross-section dimensions of the rods are less than the widths of the cavity openings. Either the rods are compressed, or the cavity openings are expanded, or both, so as to enable manually inserting the rods into the cavities. Elongate thermal breaks may be installed at and adjacent the cavities, to assist in controlling thermal conduction through the closure members, between the outside environment and the enclosed space above the roof opening.

This disclosure relates to a louvered patio cover. The louvered patio cover may comprise a frame with support beams, louvered panels, support beam couplers, an actuator, a gutter, and/or other components. The support beams may have angled ends. The louvered panels may be rotatably coupled to the support beams. A support beam coupler may comprise first and second receivers. The first receiver may be configured to receive an angled end of a first support beam, and the second receiver may be configured to receive an angled end of a second support beam. The angled ends of the first and second support beams may face, meet, and/or abut each other when received by the first and second receivers. The actuator may be configured to rotate the louvered panels. A gutter may comprise a lighting channel configured to hold a light source for lighting an area under the louvered patio cover.

A roof load support structure supports a load on a sloping metal panel roof such that substantially all of the load is conveyed through rails, which are mounted on roof panel ribs, then through the roof panel ribs, and to underlying building support structure. Minor portions of the load can be conveyed through an upper diverter and a lower closure. The upper diverter diverts water laterally away from the support structure, in two opposing directions to two opposing sides of the support structure.

A walkable skylight lighting system, installed to a roofing structure, including a skylight having a pane and framing members that surround and support the pane, and including a paving surface, the paving surface having a plurality of pavers that extend immediately adjacent to the skylight. The pane is an insulating glass unit (IGU) having structural glass panels and a thermal panel that are separated and sealed by a spacer, and separately supported so that they do not crush the spacer. The framing members include an upper framing member that has a lighting channel containing an LED lighting strip that edge lights the structural glass panels in the pane.

In the roof window (1), each sash member (31, 32) comprises a profile element (31a, 32a), an inner element (32c) and an intermediate element (31b, 32b) forming a connection between the profile element and the inner element of each sash member in an assembled condition of the sash (3). The profile elements (31a, 32a) of the sash members (31, 32) are located along respective exterior edge portions of the pane (4) in the assembled condition of the sash (3), and the profile elements (31a, 32a) of the top sash member (31) and the two side sash members (32) are formed as a set of longitudinal profiles of substantially uniform cross-section.

In the roof window, the frame (2) comprises at least one releasable component (24c, 24d) configured to allow replacement with a different set of components to change the functionality of the roof window (1). Specifically, one releasable component comprises a cover (24c) releasably connected to remaining components of the bottom frame member (24) and defining a cavity relative to the remaining components of the bottom frame member (24).

In the roof window, an interface unit (8) is provided to interact with auxiliary equipment and/or other components of the roof window (1) in an assembled condition of the frame (2). The interface unit (8) comprises a top interface element and two side interface elements (82, 83) received in a receiving structure comprising an interface unit groove in an exterior side of the top frame member and two side members (22, 23).

A roof window (1) comprising a frame (2), a sash (3) carrying a pane (4), where the frame (2) comprises an interface unit (8) extending in the length direction (L) of at least one frame member (21, 22, 23, 24). At least one flashing member (1011, 1012, 1013, 1014) comprises a flange (1017) inserted in a flashing reception groove (85) in the interface unit (8) in a direction parallel to the frame plane (F), said flashing reception groove (85) extending in the length direction (L) of the frame member (21, 22, 23, 24). One or more protrusions (85a) are provided in the flashing reception groove for engagement with the flange(s) (1017) and extend(s) in the length direction (L) and is/are made by co-extrusion with one or more parts (80, 86, 88) of the interface unit (8) delimiting the flashing reception groove. A method for mounting a roof window is also disclosed.

Provided is an automated self-cleaning skylight including a frame (1) fitted with glass (2) and installed with guide rails (3) on both sides of the frame that guides a wiper beam (12) consisting of wiper blade guide plates (9) and driven by a motor (4) with both sides being connected to shafts (5), wherein at opposite corners of the frame are located with spray nozzles (13) via which a cleaning solution is sprayed, and one side of the shafts is connected to a rotating pulley (6) that connects to a drive belt (8) connected to a tension pulley (7). When the shaft is rotated by the motor, the rotating pulley and the tension pulley are in turn rotated, causing the drive belt to shift and drive the wiper blade guide plates attached to the drive belt and a wiper blade (17) inserted into a groove in the wiper beam.

Lighting devices and methods for providing daylight to the interior of a structure are disclosed. Some embodiments disclosed herein provide a daylighting device including a tube having a sidewall with a reflective interior surface, a light collecting structure, and a light reflector positioned to reflect daylight into the light collector. In some embodiments, the light collector is associated with one or more light-turning and/or light reflecting structures configured to increase the amount of light captured by the daylighting device. Optical elements may allow for the absorption and/or selective transmission of infrared light away from an interior of the daylighting device.
