A middle flashing assembly for use in a roof window arrangement with a first roof window located above a second roof window when seen in the direction of inclination of the roof structure is disclosed. It comprises a middle flashing member configured for extending between the roof windows and having at least one engagement section configured for engagement with a connector element extending from the first roof window towards the second roof window. It further comprises an edge supporting rail and an edge gasket both extending on the interior side of the middle flashing member in parallel with a longitudinal edge. The edge gasket is located between the middle flashing member and the edge supporting rail in the mounted state. An end section extends beyond the middle flashing member in the length direction for engagement with the connector element. A method for weather-proofing a roof window arrangement is also disclosed.

According to the invention, a skylight including a frame is disclosed. The skylight may include a frame. The frame may include a vertical curb and horizontal flashing integral with, and extending away from, a bottom of each exterior side of the vertical curb. The frame may also include a first vertical member extending upward from the horizontal flashing which extends from a first exterior side of the vertical curb, and a second vertical member extending upward from the horizontal flashing which extends from a second exterior side of the vertical curb, where the second exterior side is opposite the first exterior side. The frame may further include a first horizontal member extending from the first vertical member, and away from the vertical curb, as well as a second horizontal member extending from the second vertical member, and away from the vertical curb.

A sealing gasket (4) for use between flashing members (31,32) is disclosed. It comprises a compressible sealing section and an attachment section comprising at least two legs configured for engagement with a flashing member, both sections extending over substantially the entire length of the sealing gasket. The at least two legs of the attachment section project from a base section of the attachment section so that a first recess and a second recess extending in parallel are defined, said first and second recesses being configured for engagement with a flange, ridge, or leg on a flashing member. The invention further relates to a flashing arrangement and to a method of sealing a gap between flashing members for a roof window.

The present disclosure concerns a skylight protection assembly to protect a skylight of a roof. The skylight protection assembly comprises a frame superposable to a mounting surface of the roof to surround at least partially the skylight and securable to the roof, the frame comprising at least one frame member having a roof-engaging portion, a screen-supporting portion and an outer side; a protection screen engageable with the screen-supporting portion of said at least one frame member to define with the frame a skylight protection chamber configured to contain the skylight. The frame member comprises an upper frame member, the outer side of the upper frame member having a water-flowing profile considered in a plane substantially parallel to the mounting surface of the roof. The present disclosure also concerns a method for protecting a skylight of a roof.

The roof window system (1) is configured for being mounted in an opening in a roof structure (23) of a building and includes a ventilation unit (5) configured for being mounted adjacent to a roof window (13) and adapted for providing ventilation of the interior of the building in which the roof window is mounted. The roof window comprises a frame (2) defining a frame plane and including a pane (4) mounted in said frame. The frame comprises a top frame member (2a) intended for being located highest in the mounted state when seen in the direction of inclination of the roof structure, a bottom frame member opposite the top frame member, and two side frame members extending between the top frame member and the bottom frame member, said frame members together form a window structure delimiting a frame opening and each having an interior side (2f) intended for facing the interior in the mounted state, an exterior side intended for facing the exterior, an inner side (2d) facing the frame opening and an outer side (2e) facing away from the frame opening. The ventilation unit is configured for being arranged primarily adjacent to the outer side of a frame member, and comprises a lower side (24) configured for being arranged adjacent to or at the interior side (2f) of said frame member (2a). The roof window system further comprises a ventilation panel (3) allowing air passage from one side of the ventilation panel to another side of the ventilation panel, thereby defining an intended air flow direction, said ventilation panel being configured for facing the interior of the building and extending away from the interior side of the frame member adjacent to which the ventilation unit is mounted.

In a roof window system, the housing (6) of the ventilation unit (5) is prepared for accommodation of a standard ventilator and/or a regenerator allowing an air current through a ventilation passage (28), from an exterior grating (18) to a ventilation panel (3) integrated into or in continuation of a lining panel of a room in the interior of the building in which the roof window is installed.

In a roofing structure, two roof panels with different slopes and lengths are positioned back-to-back, the vertical back walls of the panels having a uniform height. The seam between the two differently-sloped panels are connected by a ridge cap set at a uniform height. The ridge cap covers the seam, extending on both sides to a distance from the back walls of the roof panels sufficient to create a capillary break therefrom (preventing moisture migration) and then downwards and slightly towards the back walls of the roof panels, thereby using gravity to direct the water into the downward sloping roof panels.

An end closure for a cladding for a first roof window forming part of a roof window arrangement mounted in an inclined roof structure, where said first roof window is above a second roof window when seen in the direction of inclination of the roof structure and where a middle flashing member is arranged between the roof windows is disclosed. The end closure comprises an end plug having a male connector section configured to be inserted in a hollow section of the cladding and an end gasket configured to come into a sealing engagement with the middle flashing member. The end gasket is arranged at the interior side of the end plug and extending from one side surface to the other. The end closure may further include a covering plug configured for interconnecting the end plug with a covering extending along a lower edge of the first roof window.

A connector element for a flashing assembly for use in a roof window arrangement is disclosed. The exterior side of the connector element comprises a gutter with two longitudinal edges configured for engagement with an engagement section of a flashing member. A connecting section is configured for being connected to a bracket used for connecting a roof window to a load-bearing structure of the roof structure. The connector element is configured for being arranged with a first end at an outer side of a bottom frame member of a first roof window and a second end at a second roof window. At least one attachment element is provided on an end surface at the second end, said attachment element being adapted for engagement with a supporting element of a flashing assembly. A method for weather proofing a roof window arrangement is also disclosed.

The invention provides a system for installing a load on a metal panel roof, the system comprising a rail and closure structure adapted to be supported by ribs defined by the roof panels, and a load adapted to be supported on the rail and closure structure. In some embodiments, standing seams on ribs, and side rails on the rail and closure structure, extend parallel to each other, and optionally parallel to opposing sides of a hole in the roof. In some embodiments, substantially all of a downwardly-directed force of the load passes downwardly through the rail and closure structure to the ribs, and from the ribs to underlying structural members of the building.
