The addition of up to 16-3/4 inches of 0.5 pcf glass fiber insulation (R-40), either faced or <br /> unfaced batt, or loose-fill to any 1- or 2-hour fire-resistance rated floor-ceiling or roof-ceiling system <br /> having a cavity deep enough to,accept the insulation is permitted, provided that one additional layer <br /> �i <br /> of either 1/2 inch type X or 5/8 inch type X gypsum panels is applied to the ceiling. The additional <br /> layer of gypsum panel shall be applied as described for the face layer of the tested system, except <br /> that the fastener length shall be increased by not less than the thickness of the additional layer of <br /> gypsum panel. <br />
