A wood or engineered wood structural panel, such as, but not limited to, OSB (“oriented strand board”) or plywood, that is both fire-resistant and water resistant. The panel is factory-coated with a product that provides fire resistance. The treatment gives it a Fire-Resistant (FR) performance (for use in a one- or two-hour rated assembly). The panel also is overlaid or coated in a factory setting with a weather/water resistive barrier (WRB). The structural panel thus combines a fire-resistant structural sheathing and WRB product in one integrated panel produced at a factory prior for installation at a job site.

A covering panel for buildings includes: A) a ferromagnetic layer containing ferromagnetic material; B) one or more structural layers made of one or more materials which are substantially non-ferromagnetic; C) a signal light, which is visible, observing the major front face of the covering panel from the outside; and D) one or more wireless power supply stations, each of which supplies power to one or more electrical or electronic devices. The signal light is arranged at, or close to, one of the wireless power supply stations, for example, at, or close to, its possible inductor or capacitive plate, to allow a user to easily find the position of the power supply station, even though it is hidden in or behind the covering panel.
