Abstract
Abstract An apparatus is disclosed for eliminating moisture from a moist-prone area such as an insulated roof or the like. The invention comprises a grid of hydrophilic material adjacent the moisture prone area. The grid comprises a first set of longitudinally extending hydrophilic elements and a second set of longitudinally extending hydrophilic elements disposed in a transverse relationship to the first set of hydrophilic elements. The grid enables moisture to travel along the first and second set of hydrophilic elements by capillary action. A vent is included for venting moisture accumulated in the first and second set of hydrophilic elements to remove moisture thereby.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
186 words
An apparatus for eliminating moisture in an insulated roof system having a roof deck and insulation disposed thereon covered by a waterproof layer, the improvement comprising: a grid of hydrophilic material disposed adjacent the insulating layer; said grid comprising a first set of longitudinally extending hydrophilic elements; said grid further comprising a second set of longitudinally extending hydrophilic elements disposed in a transverse relationship to said first set of hydrophilic elements enabling moisture to travel along said first and second sets of hydrophilic elements by capillary action, each of said elements of said first and said second set being enclosed within a vapor impervious shield; first aperture means disposed in said vapor impervious shield enabling moisture to enter therein to input said grid elements; second aperture means disposed in said vapor impervious shield to enable evaporation of moisture from said grid elements; and means for venting the moisture accumulated in said first and second sets of hydrophilic elements through said second aperture means enabling the moisture accumulated within said grid to flow toward said means for venting thereby reducing the moisture within the moisture prone area.
Claim 2
Independent Claim
186 words
An apparatus for eliminating moisture in an insulated roof system having a roof deck and insulation disposed thereon covered by a waterproof layer, the improvement comprising: a grid of hydrophilic material disposed adjacent the insulating layer; said grid comprising a first set of longitudinally extending hydrophilic elements; said grid further comprising a second set of longitudinally extending hydrophilic elements disposed in a transverse relationship to said first set of hydrophilic elements enabling moisture to travel along said first and second sets of hydrophilic elements by capillary action, each of said elements of said first and said second set being enclosed within a vapor impervious shield; first aperture means disposed in said vapor impervious shield enabling moisture to enter therein to input said grid elements; second aperture means disposed in said vapor impervious shield to enable evaporation of moisture from said grid elements; and means for venting the moisture accumulated in said first and second sets of hydrophilic elements through said second aperture means enabling the moisture accumulated within said grid to flow toward said means for venting thereby reducing the moisture within the moisture prone area.
Claim 3
Dependent Claim
46 words
An apparatus as set forth in claim 1, wherein said venting means includes a third hydrophilic element at least partially exposed to the ambient and in communication with at least one of said first and second sets of hydrophilic elements for enabling evaporation of accumulated moisture.
Claim 4
Dependent Claim
21 words
An apparatus as set forth in claim 1, wherein said hydrophilic grid is interposed between insulating portions of the roof insulation.
Claim 5
Dependent Claim
28 words
An apparatus as set forth in claim 1, wherein the grid is disposed on a surface of the insulation extending substantially parallel to the roof of the building.
Claim 6
Dependent Claim
34 words
An apparatus as set forth in claim 1, wherein said vent means includes said second aperture means being disposed in fluid communication with a vent pipe extending through the insulation and the waterproof covering.
Claim 7
Dependent Claim
24 words
An apparatus as set forth in claim 1, wherein each of said grid elements includes a sub-grid element disposed in said vapor impervious shield.
Claim 8
Dependent Claim
26 words
An apparatus as set forth in claim 1, wherein each of said grid elements includes a substantially solid hydrophilic material disposed in said vapor impervious shield.
Claim 9
Dependent Claim
43 words
An apparatus as set forth in claim 2, wherein said third hydrophilic element comprises a solid hydrophilic material disposed about the periphery of the roof and extending along the sidewall of the building with the terminating edge thereof being exposed to the ambient.
Claim 10
Dependent Claim
34 words
An apparatus as set forth in claim 2, wherein said third hydrophilic element comprises a solid hydrophilic material in fluid contact with said grid and extending adjacent a preexisting vent in the building system.
Claim 11
Independent Claim
160 words
An apparatus for eliminating moisture within a moisture prone area, comprising in combination: a grid of hydrophilic material disposed adjacent the moisture prone area; said grid comprising a first set of longitudinally extending hydrophilic elements disposed in a transverse relationship to said first set of hydrophilic elements enabling moisture to travel along said first and second sets of hydrophilic elements by capillary action, each of said elements of said first and said second set being enclosed within a vapor impervious shield; first aperture means disposed in said vapor impervious shield enabling moisture to enter therein to input said grid elements; second aperture means disposed in said vapor impervious shield to enable evaporation of moisture from said grid elements; and means for venting the moisture accumulated in said first and second sets of hydrophilic elements through said second aperture means enabling the moisture accumulated within said grid to flow toward said vent thereby reducing the moisture within the moisture prone area.
Claim 12
Independent Claim
160 words
An apparatus for eliminating moisture within a moisture prone area, comprising in combination: a grid of hydrophilic material disposed adjacent the moisture prone area; said grid comprising a first set of longitudinally extending hydrophilic elements disposed in a transverse relationship to said first set of hydrophilic elements enabling moisture to travel along said first and second sets of hydrophilic elements by capillary action, each of said elements of said first and said second set being enclosed within a vapor impervious shield; first aperture means disposed in said vapor impervious shield enabling moisture to enter therein to input said grid elements; second aperture means disposed in said vapor impervious shield to enable evaporation of moisture from said grid elements; and means for venting the moisture accumulated in said first and second sets of hydrophilic elements through said second aperture means enabling the moisture accumulated within said grid to flow toward said vent thereby reducing the moisture within the moisture prone area.
