A multi-layer fire-resistant (FR) panel or board, for use in exterior applications, such as siding, cladding, trim, fencing, or sheathing. The panel or board may be OSB or other form of engineered-wood, with an integrated fire-resistant laminate incorporated during a manufacturing process. The laminate may be placed on top of or under a fines layer. The laminate may be placed under an overlay layer, such as a resin-impregnated paper overlay, or other form of weather- or water-resistant barrier (WRB). The laminate itself may also serve as a WRB, and may thus be combined with or substituted for the overlay layer. A second FR laminate may be applied on the bottom of the panel or board. In addition to providing FR characteristics, the laminate also protects the structural integrity of the panel by preventing or reducing the splitting and/or cracking of the panel or board during a fire event.
