Weatherproof building envelope

A method for attaching weatherproof quadrilateral panels to a building roof, comprising the steps of:

• a) providing a plurality of weatherproof panels;
• b) installing the panels with respect to a line of slope of the building roof in a diagonal position with through openings on opposing corners of each panel and mutual overlapping of the panels in the direction of the roof slope;
• c) arranging and overlapping adjacent ones of the panels next to one another at the same height with respect to the line of slope and mutually spacing apart from one another in a direction perpendicular to the line of slope;
• c) connecting overlapping panels in the line of slope through upper and lower through openings on each panel with a fastener;
• and
• d) suspending the overlapping panels above the building roof by a holding element having a slot between an upper sealing element and a lower base element for receiving one of the plurality of weatherproof panels therein, the holding element having a through opening on the upper sealing element and lower base element corresponding and aligned with the upper and lower through openings on overlapping panels to affix the overlapping panels to the roof of the building by the fastener extending through the through openings of the holding element and the overlapping panels into the building roof.

A method for preparing a building envelope with several quadrilateral weatherproof panels, comprising the steps of:

• a) providing a plurality of weatherproof panels;
• b) installing the weatherproof panels with respect to a line of slope of a building roof in a diagonal position with mutual overlapping, each of the panels including an edge region with an upper corner and a lower opposing corner and said mutual overlapping including an arrangement wherein directly adjacent weatherproof panels overlap each other over at least part of a length of their edge regions;
• c) arranging adjacent ones of the weatherproof panels next to one another at the same height with respect to the line of slope and mutually spaced apart a predetermined distance from one another in a direction perpendicular to the line of slope;
• d) connecting the overlapping weatherproof panels to a bearing structure of the roof by connecting the upper corner of one panel to the lower corner of the overlapping panel with respect to the line of the slope;
• and
• e) suspending and sealing the one panel to the overlapping panels above the roof by a holding element having a sealing top element and a base element in contact with the roof of the building and affixedly attached thereto by a fastener passing through the overlapping panels and the holding element.
