A curb-mounted skylight designed for mounting on a framing protruding from the roof and forming part of its construction. The skylight has a glazing unit (1) and a support frame (2), where the distance (H2) from the skylight support surface to the outermost edge of the protective wall (22) of the section profile of the support frame (2) is not longer than the distance (H1) from the skylight support surface to the outside surface of the glazing unit (1). There is an adhesive sealing joint (5) between the glazing unit (1) and the protective wall (2).

A vacuum insulated glass (VIG) unit frame assembly (10) is disclosed comprising: a rectangular vacuum insulated glass unit (1) comprising two glass sheets (2a, 2b) separated by a sealed gap (11), wherein a plurality of support structures (12) are distributed in said gap (11), and a frame arrangement (20) comprising elongated frame profile arrangements (20a-20d) which frames said vacuum insulated glass unit (1) in a frame opening (21), and wherein said frame arrangement (20) comprises a fixation system (40, 45a, 45b, 80, 28a, 28b, 22, 23, 40) fixating the vacuum insulated glass unit (1) at the frame arrangement (20), wherein said frame (20) is arranged so as to allow edges (8a-8d) of said vacuum insulated glass unit (1) to thermally deflect (DIS4) in a deflection direction (D1, D2) perpendicular to said frame opening plane (P2) due to a temperature difference (?T=T1?T2) between the two glass sheets (2a, 2b), and to provide a restriction of said thermal deflection (DIS4) of the edges (8a-8d), so as to reduce the magnitude of the thermal deflection compared to an unrestricted thermal deflection of the edges (8a-8d) at said temperature difference (?T=T1?T2).

The present subject matter provides apparatus for connecting a roof assembly to a membrane using at least one backer rod connected to the membrane, including: counterflashing disposed about the perimeter of the roof assembly, the counterflashing including a plurality of grips configured to receive and engage the at least one backer rod in contact with the membrane, so as to hold the membrane securely in position and maintain a weather seal at a desired flashing height of the membrane. In various examples, the roof assembly includes a roof hatch, window, or other fenestration unit. In various examples, the present subject matter provides a hatch attached to a wall for sealing an opening. In various examples, the present subject matter provides a method for operating a roof assembly for connection to a roof membrane.

Embodiments of the present invention comprise pre-fabricated domed skylight panel assemblies for use within steel decking systems. The skylight within the pre-fabricated domed skylight panel assembly is domed. Extending from the width-wise ends of the domed portion are respective skylight end extension portions for overlapping with adjacent steel decking panels or for coupling within an aperture of a decking panel. Further, extending from the length-wise edges of the dome portion are skylight edges configured for connection to decking panel edges (e.g., male and female rail edges or panel edges) that are configured for connection to edges of adjacent decking panels. The pre-fabricated domed skylight panel assemblies provide the desired light into the building, structural support in the steel decking system, ease of shipping of the domed skylight panel assemblies, ease of installation of the domed skylight panel assemblies at the building site, and a water tight seal.

The invention provides a system for installing a roof penetrating structure to a metal roof, the system comprising: a) a rail and closure structure adapted to be supported by adjacent rib elevations of said roof; b) a skylight adapted to be supported on the rail and closure structure; and c) a support member for sealing a cut away portion of the rib structure to divert water away from the rail and closure structure.

The invention provides a system for installing a rail and closure assembly on a metal roof. The rail and closure assembly includes a supporting rail and closure structure adapted to be supported by adjacent rib elevations of the roof, and an overlying load adapted to be supported by the rail and closure structure. The rail and closure structure diverts water around the rail and closure assembly. The entire heights of the side rails, including the rail bottoms, are above the closest portions of the panel flats. At least one panel of each of the side rails faces the respective rib along the full length of the respective side rail. The rail and closure assembly also includes a lower closure. Opposing ends of the lower closure extend upwardly and interface with the ribs. The lower closure further comprises a lower flange which interfaces with a respective panel flat.

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, thence 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. The support structure spans at least first and second ones of the roof panels. Cut, terminal ends of an intermediate rib are cantilevered from purlins immediately above and below the support structure, and thus support middle portions of the upper diverter and the lower closure.

A vacuum insulated glass (VIG) unit frame assembly is disclosed comprising: a rectangular vacuum insulated glass unit comprising two glass sheets separated by a sealed gap, wherein a plurality of support structures are distributed in the gap, and a frame arrangement comprising elongated frame profile arrangements which frames the vacuum insulated glass unit in a frame opening, and wherein the frame arrangement comprises a fixation system fixating the vacuum insulated glass unit at the frame arrangement, wherein the frame is arranged so as to allow edges of the vacuum insulated glass unit to thermally deflect in a deflection direction perpendicular to the frame opening plane due to a temperature difference (T=T1T2) between the two glass sheets, and to provide a restriction of the thermal deflection of the edges, so as to reduce the magnitude of the thermal deflection compared to an unrestricted thermal deflection of the edges at the temperature difference (T=T1T2).

A prefabricated skylight and curb assembly and method for installing and fabricating same is disclosed. The skylight and curb assembly of the present invention may include a roof curb, a skylight, and a locking cap. The roof curb may define an outer perimeter and an inner open perimeter. Further, the roof curb may include a lower end for securing to a roof structure and an upper end for rigidly securing the skylight. The locking cap may include a retainer and a cover. The retainer may be disposed on the outer perimeter of the roof curb between the upper and lower ends. The cover may be adjustably secured to the retainer so that the cover may be moveable between a generally vertical position and a generally horizontal position.

A skylight assembly, having framing members that define an interior space and rafters that span the interior space between framing members, the framing members having an upper support surface for supporting panes of glass, each pane having at least one structural glass panel and a thermal panel. A structural thermal break connected to each framing member provides a lower support surface. The structural glass panels are fully supported by the upper support surface. The thermal panel is supported by the lower support surface, and is sealed to the upper support surface by a spacer, forming an insulating glass unit therewith. The full support of the structural glass, independent of the support of the thermal panel, allows the skylight to be thermally insulated and walkable.
