ABSTRACT:
A wicking apparatus for drying insulation wet with water, particularly insulation in flat roofing systems and wall systems, is disclosed consisting of a hollow device, capable of penetrating the exterior weather shield or siding to the insulation to create a passageway from the insulation to an external environment where moisture can evaporate, and a wick disposed within the passageway to transport moisture by capillary action from the insulation to the external environment. In retrofit applications, the method resides in penetrating the weather shield or insulation in at least one location and deploying the wicking apparatus to induce drying; in new applications a network of moisture-transporting channels can also be employed within the insulation itself together with one or more wicking apparatuses to further aid in drying.
