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.

Metal panel roofs, and load support structures for supporting loads on such roofs. Side rails provide primary support for loads on such roofs. The side rails can be fabricated from sheet metal or can be extruded. A side rail includes a standing seam cavity which is lowered, and covers, the standing seam. Side walls of the standing seam cavity. An upstanding web extends up from the cavity, and lower shoulders may extend laterally, optionally downwardly, from the walls which define the cavity, on either one side, or both sides, of the cavity. Building roof insulation can extend up through an aperture in the roof, surrounded by such load support structure, and extend up to the top of the side rail, thus providing a thermal break between the load support structure elements and the space surrounded by the load support structure.

A lamination glass sheet (14) is attached to an outer major surface (4a) of said first glass sheet (2a) by means of a lamination layer (16), and wherein said sealing system (1c) extends into a hole (14a) in the lamination glass sheet (14), and the edge (8a-8c) of the vacuum insulated glass unit (1) proximate the hole (14a) in the lamination glass sheet (14), said sealing system (1c) and said hole in the lamination glass sheet (14) into which the sealing system (1c) extends are covered by the frame (20). The disclosure additionally relates to a retrofitting frame system (100) and a laminated vacuum insulated glass unit (1).

A cover assembly (100) for at least one roof penetrating structure (1), such as a roof window, is disclosed. It comprises a first cover member (10) comprising a pocket (106) extending along a pocket plane (P), and a second cover member (20) comprising an edge flange (202) extending in an edge flange plane (F) and having a bent edge (2051). The bent edge (2051) of the edge flange comprises a compacted section (2053) closest to the bend line and a lip section (2054) extending from the compacted section at an angle (A) to the flange plane, and the pocket height (PH) is larger than the edge flange height (EH) at the compacted section and smaller than the maximum edge flange height (EHL) at the lip section. A method for mounting cover members of a cover assembly is also disclosed.

A roof window (1) comprising a frame (2), a sash (3), a pane element (4), and a covering assembly (10), the covering assembly (10) comprising a diverter rail (103), where the diverter rail (103) extends along a top frame member (21) in a length direction and projects from the top frame member, forming a diverter angle (A) of 45-89 degrees with respect to a plane (C) defined by an exterior surface (4e) of the pane element (4).

In the roof window, the hinge assembly (9) comprises means to allow the sash (3) to be rotated about a substantially horizontal second hinge axis () at a distance from the top frame member and top sash member to provide a plurality of additional open positions in a second operational condition. A sash installation component (35) is provided to support the sash (3) in the second operational condition of the roof window (1).

In the roof window (1), each sash member (32) comprises a profile element (32a), an inner element (32c) and an intermediate element (32b) forming a connection between the profile element and the inner element of each sash member. The inner elements (32c) of the sash members (32) form a coherent inner element sash structure supporting an interior edge portion of the pane (4) and the profile elements (32a) of the sash members (32) are located along respective exterior edge portions of the pane (4). The intermediate element (32b) of each sash member (32) comprises engagement means (32b3) configured to form a structural connection with the inner element (32c) in one of at least two distinct positions in the height direction.

In the roof window (1), each mounting bracket (6) comprises a first bracket leg (61) for fastening to the roof structure and a second bracket leg (62) for fastening to the frame (2) of the roof window (1). The second bracket leg (62) of each mounting bracket (6) is provided with a first engagement means (624) in a first section (621) of the second bracket leg (62) and a second engagement means (629) in a second section (626) of the second bracket leg (62). The second engagement means (629) is configured to assume an inactive position and an active position, and the first engagement means (624) is configured to be received in one receiving structure (27) of the outer side of the frame member (22) in the mounted condition of the mounting bracket (6) on the frame (2) of the roof window (1), and said second engagement means (629) is configured to be received in another receiving structure (27b) of the outer side of the frame member in the mounted condition of the mounting bracket (6) on the frame (2) of the roof window (1) in its active position only.

In the roof window, each frame member (22) comprises a plurality of receiving structures at an interior, exterior, inner and/or outer side. The receiving structures comprise a number of grooves (25, 26, 27, 28) to interact with auxiliary equipment in an assembled condition of the frame.

A skylight having a frame with a flanged lip about a skylight window unit periphery having water drainage notches formed therein help keep the windows clean. The notches in the frame flange radiates outward from a central light transmissive region of the window unit and have an inboard depth adjacent the window opening approximately equal to the flange thickness. Inclination of the skylight when installed allows water to freely drain from through the notches off the central light transmissive region of the window unit.
