Exterior sheathing panel with integrated air/water barrier membrane

At least one of these or other problems is reduced using a building material that is uniquely identifiable. A method of making an identifiable gypsum-based building product includes selecting a tagging material occurring naturally in a component of the building material and choosing a carrier substance having a high concentration of the tagging material. By selecting an amount of the carrier substance and adding it to the building material, a building product having a unique product characteristic is created. In a second embodiment of the invention, a second tagging material is combined with the first tagging material to create a unique product. In yet another embodiment of the invention, a supplemental amount of the tagging material is added to the gypsum-based composition in addition to the carrier substance. Some tagging materials are useful in a gypsum-based composition to produce a visual confirmation of the presence of the tagging material.
