Abstract
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.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
109 words
An apparatus for drying insulation after installation comprising: (a) a penetrating means for creating a passageway between the space occupied by the insulation and an exterior environment where unwanted moisture can be carried away by evaporation; and (b) wicking means within the passageway for transporting moisture by capillary action from the insulation to the external environment; and wherein the penetrating means is a hollow device adapted to receive the wicking means within itself and having at least one opening through which the wicking means may contact the insulation and further having at least one other opening through which moisture may evaporate from the wicking means to the external environment.
Claim 2
Independent Claim
109 words
An apparatus for drying insulation after installation comprising: (a) a penetrating means for creating a passageway between the space occupied by the insulation and an exterior environment where unwanted moisture can be carried away by evaporation; and (b) wicking means within the passageway for transporting moisture by capillary action from the insulation to the external environment; and wherein the penetrating means is a hollow device adapted to receive the wicking means within itself and having at least one opening through which the wicking means may contact the insulation and further having at least one other opening through which moisture may evaporate from the wicking means to the external environment.

Claim 14
Independent Claim
97 words
A method of drying wet insulation material when the material is separated from an external environment by a sealing surface, the method comprising: (a) penetrating the surface to create a passageway between the material and the external environment; (b) disposing a housing within said passageway, said housing having a wicking means within itself and having at least one opening through which the wicking means may contact the insulation and further having at least one opening through which moisture can evaporate from said wicking means to said external environment; and (c) sealing said housing to said sealing surface.
Claim 15
Independent Claim
97 words
A method of drying wet insulation material when the material is separated from an external environment by a sealing surface, the method comprising: (a) penetrating the surface to create a passageway between the material and the external environment; (b) disposing a housing within said passageway, said housing having a wicking means within itself and having at least one opening through which the wicking means may contact the insulation and further having at least one opening through which moisture can evaporate from said wicking means to said external environment; and (c) sealing said housing to said sealing surface.
Claim 16
Dependent Claim
121 words
A roofing system comprising: (a) a support structure situated upon the roof; (b) insulating material adapted to be received within the support structure; (c) a sealing means for sealing the insulation into the support structure; (d) at least one wicking apparatus comprising: (i) a penetrating means for creating a passageway between the insulating material and an external environment; and (ii) a wicking means within the passageway for transporting moisture to the external environment and (e) a network of moisture-carrying channels within the insulating material for transporting moisture to the wicking means; and wherein the wicking apparatus, insulating material and moisture-carrying channels are formed as cellular units adapted to be received by the support structure and then covered by the sealing means.
Claim 17
Dependent Claim
121 words
A roofing system comprising: (a) a support structure situated upon the roof; (b) insulating material adapted to be received within the support structure; (c) a sealing means for sealing the insulation into the support structure; (d) at least one wicking apparatus comprising: (i) a penetrating means for creating a passageway between the insulating material and an external environment; and (ii) a wicking means within the passageway for transporting moisture to the external environment and (e) a network of moisture-carrying channels within the insulating material for transporting moisture to the wicking means; and wherein the wicking apparatus, insulating material and moisture-carrying channels are formed as cellular units adapted to be received by the support structure and then covered by the sealing means.
