Abstract
A method of forming a building panel is provided, with the building panel including facer and liner sheets surrounding a foam core. The method includes the steps of pre-notching the facer sheet at each false joint, roll forming the side joints of the facer sheet, bending the facer sheet, via a press operation, at the pre-notched area to form the false joint, such that the facer sheet is a continuous sheet across the false joint, and bonding the facer sheet having the false joint and the liner sheet to the foam core to form the building panel.
