The structural panel is made of gypsum, where one of the upper surfaces is covered with a metal foil and the metal foil is perforated. The metal foil is made of aluminum, zinc, tin or alloys of these metals. The structural panel comprises a gypsum core and a single or double sided sheathing with a fleece. The metal foil is provided with a paper layer on single or both sides. An independent claim is included for a method for manufacturing a structural panel.
