Abstract: A rolled sheet product, the sheet product comprising a top layer and a bottom layer, the top layer being less ductile than the bottom layer, and the top layer facing outward in the rolled sheet product. A method of packaging a sheet product comprising a top layer and a bottom layer, the top layer being less ductile than the bottom layer, comprising winding the sheet product into a roll such that the top layer faces outward.

Abstract: A compliance system configured to assist a user with the selection of building materials that comply with a regulatory requirement includes a processor, a forms generator, and a user interface. The processor is programmed to receive a first user input via the user interface, which first user input identifies a geographic area within a larger compliance region to which the regulatory requirement relates. The geographic area has particular compliance parameters associated therewith. The processor also is programmed to receive a second user input via the user interface, which second user input identifies a first building material, based on the first and second user inputs, identify a second building material usable in combination with the first building material to comply with the regulatory requirement, and, via the forms generator, generate one or more forms that document compliance with the regulatory requirement.
