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.

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 mounting mechanism for connecting mechanical equipment to any mounting surface has an upper (floating) portion, and a lower (fixed) portion. The mechanical equipment is mounted to the upper portion, and the lower portion is mounted to the mounting surface. The upper portion and lower portion are connected to each other via a connection mechanismpreferably a resilient connection mechanism. A restraint mechanism is attached to both the upper portion and the lower portion on the side of the upper and lower portion that faces away from the equipment. The restraint mechanism provides positive restraint at a rate of at least 5 pounds per linear inch of length but can provide much higher than that. The restraint mechanism is flexible to allow for isolation of the equipment.

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.

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.

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.

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.
