A fire resistant shutter is provided including a first panel including wood and a second panel including a cementitious material located adjacent to the first panel. The fire resistant shutter further includes a hasp attached to the second panel and configured to be attached to a building structure with a detachable connector, and a pin including wax disposed in an aperture defined by the hasp. The pin prevents the hasp from opening. When the fire resistant shutter is attached to a building structure, heat from an approaching fire at least partially melts the pin, which opens the hasp, detaches the connector, and allows the shutter to drop. The deployed shutter provides fire resistance to the building structure, such as at a window.
