A ratio between an area of the vent slot to an area of the outlet is less than 0.33. The air circulating unit includes a window movable between a closed position to block the outlet, and an open position where the outlet is unblocked and cooperates with the vent opening and the air chamber to form a second venting pathway.

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 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. 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 roof hatch for enabling access to a rooftop of a building from an interior of the building includes a curb adapter configured to be disposed over a curb of the rooftop. The curb is formed around an opening in the rooftop that fluidly connects the interior of the building to an exterior of the building. Additionally, the roof hatch includes a cover coupled to the curb adapter by a pivoting member. The cover includes a support extending within an interior length of the cover. The roof hatch includes a gas spring coupled between the support and the curb adapter. The gas spring is configured to apply a force to the support, and the support is configured to distribute the force along the interior length of the cover.

The present disclosure relates to an aperture cover such as a window or a door. The aperture cover comprises a vacuum insulated glass unit (3), and a frame (2, 17) such as a sash. The frame (2, 17) comprises elongated structural frame members (8) which together encloses a frame opening (2a). The vacuum insulated glass unit (3) overlaps (18) at least one of the elongated structural frame members (8) so that the edge surface (7) of the vacuum insulated glass unit (3) extends beyond the outer side surface (14) of the overlapped elongated structural frame member (8). The frame (2) moreover comprises an elongated connection profile (6) comprising a connection wall member (6a) which extends parallel to the overlapped structural frame member (8) and is connected to at least one of the outer major surfaces (S1, S2) of the vacuum insulated glass unit (3), and the elongated connection profile (6) comprises a fixation member (6b) which is connected to the overlapped structural frame member (8).

An architectural screen roof curb supported by an upstanding support curb to camouflage or hide various articles including, but not limited to, HVAC units. The architectural screen roof curb includes a top curb portion and two or more spaced, generally horizontal extending support members which then, in turn, support one or more architectural screens such that no portion of the architectural screen roof curb comes into contact with the underlying roof.

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 system of components for forming a skylight which includes a base frame formed from lengths of identical base frame extrusions a glazing frame formed from lengths of identical glazing frame extrusions angular corner pieces for joining the base frame extrusions and the glazing frame extrusions to form a base frame and a glazing frame respectively a glazing panel adapted to be adhered at its edges to said glazing frame and said glazing panel being adapted to be attached to said base frame. The set of component extrusions reduces the cost of making custom measured skylights. Preferably Aluminium extruded frame members are used. The glass sheet is adhered at its edges to the upper edge of a glazing support frame. The glazing support frame extrusions preferably include a protective edge that extends up from the support surface to enclose the edge of the glass sheet.

The present disclosure relates to a vacuum insulated glass (VIG) unit frame assembly (10), wherein said vacuum insulated glass unit frame assembly (10) comprises: a vacuum insulated glass unit (1), anda frame (20) comprising elongated frame profile arrangements (20a-20d) which frames said vacuum insulated glass unit (1) in a frame opening (21). One or more of said frame profile arrangements (20a-20d) comprises a holding part (28), wherein said holding part (28) holds the vacuum insulated glass unit (2) between first and second holding members (22, 23 28a, 28b,) arranged at opposite outwardly facing surfaces (4a, 4b, 15, 35a) of the vacuum insulated glass unit (1), and one or more resilient suspension elements (45a, 45b) is compressed between a first of said holding members (22, 23 28a, 28b) and one of said opposite outwardly facing surfaces (4a, 4b), and wherein one or more resilient suspension elements (45a, 45b) is compressed between a second of said holding members (22, 23 28a, 28b) and the other of said opposite outwardly facing surfaces (4a, 4b). Said compressed, resilient suspension elements (45a, 45b) provides a holding force (F1, F2) towards said opposite outwardly facing surfaces (4a, 4b, 15, 35a) of the vacuum insulated glass unit (1) so as to suspend the vacuum insulated glass unit (1) between said first and second holding members (28a, 28b), and each of said compressed, resilient suspension elements (45a, 45b) are configured to be further compressed or expand in response to a thermal deflection of the edge (8a-8d) of the VIG unit (1) due to a temperature difference (AT=71?72) between the two glass sheets (2a, 2b). The disclosure additionally relates to a vacuum insulated glass unit and a retrofitting frame system.

A skylight includes a frame that is configured to be mounted to a structure, the frame defining a central opening and a solar power unit that is coupled with the frame.
