We have to assume you have addressed the reason for the insulation failure before the correction or repair can be started. If your insulation is falling in several areas and especially if it is a climate controlled environment you may consider an upgrade to a “banded” second layer which will add an additional layer to the existing layer and holding it up together with the new second layer.
