Weather barrier for a building penetration
View Patent ↗There is provided a weather barrier for an opening in a wall of a building and a utility that passes through the opening. The weather barrier has a sheet of flexible and water resistant non-elastic material, which has an outer perimeter and an inner perimeter that defines a central passage that is larger than an outer diameter of the utility. A sheet of elastomeric material is sealably attached to the sheet of non-elastic material at the inner perimeter. The sheet of elastomeric material extends inward from the inner perimeter and defines a central opening that is smaller than the outer diameter of the utility. When the sheets of non-elastic and elastomeric material are disposed in a flat position, the sheet of non-elastic material defines a plane and the sheet of elastomeric material is parallel to and in line with the plane of the sheet of non-elastic material.
1. A method of protecting a penetration in a building against weather, the penetration comprising an opening in a wall of the building and a utility that passes through the opening, the method comprising the steps of:
providing:
a sheet of non-elastic material, the non-elastic material being flexible and water resistant, the sheet of non-elastic material having an outer perimeter and an inner perimeter, the inner perimeter defining a central passage that is larger than an outer diameter of the utility; and
a utility cover comprising a non-pliable sleeve and a flange extending perpendicularly outward from the non-pliable sleeve, wherein the flange of the utility cover is parallel to and sealably attached to the sheet of non-elastic material at the inner perimeter, the non-pliable sleeve of the utility cover extending outward from the inner perimeter of the sheet of non-elastic material and from the flange in a direction that is perpendicular to the plane of the sheet of non-elastic material, wherein the non-pliable sleeve defines a central opening that is shaped to receive the outer diameter of the utility; and
placing the utility cover over the utility such that the central opening of the non-pliable sleeve receives the outer diameter of the utility and such that the sheet of non-elastic material is adjacent to the wall of the building; and
attaching a building wrap material and the sheet of non-elastic material to the wall of the building.
2. The method of claim 1 , wherein the utility cover is molded to the sheet of non-elastic material.
3. The method of claim 1 , wherein the sheet of non-elastic material is air permeable.
4. The method of claim 1 , wherein attaching the building wrap material and the sheet of non-elastic material comprises attaching in an overlapping fashion.
5. The method of claim 1 , wherein the sheet of non-elastic material comprises a self-adhesive layer having a building-adhering area protected by a removable cover and a cover-adhering area.
6. The method of claim 5 , wherein attaching the building wrap material and the sheet of non-elastic material comprises attaching the self-adhesive layer to the building wrap material and at least one of the wall and the utility such that a seal is formed between the building wrap material and the utility.
7. The method of claim 5 , wherein the cover-adhering area is protected by a second removable cover, and further comprising the step of removing the second removable cover and adhering the utility cover to the cover-adhering area.
8. The method of claim 1 , wherein the utility cover passes through the sheet of non-elastic material such that the flange is attached to a first side of the sheet of non-elastic material and the sleeve extends outward from a second side of the sheet of non-elastic material.
9. A kit for forming a weather barrier for a penetration in a building, the penetration comprising an opening in a wall of the building and a utility that passes through the opening, the kit for forming a weather barrier comprising:
a sheet of material that is flexible and water resistant, the sheet of material having an outer perimeter and an inner perimeter, the inner perimeter defining a central passage that is larger than an outer diameter of the utility;
a self-adhesive layer on a face of the sheet of material, the self-adhesive layer having a building-adhering area protected by a first removable cover and a cover-adhering area protected by a second removable cover and surrounded by the building-adhering area; and
a utility cover comprising a non-pliable sleeve and a flange extending perpendicularly outward from the non-pliable sleeve, the flange of the utility cover comprising a surface for sealably adhering to the cover-adhering area after removal of the second removable cover, the non-pliable sleeve of the utility cover being shaped to extend outward from the inner perimeter of the sheet of material in a direction that is perpendicular to the plane of the sheet of material and defining a central opening, wherein the non-pliable sleeve is shaped to receive the outer diameter of the utility when adhered to the cover-adhering area.
10. The kit of claim 9 , wherein the utility cover passes through the sheet of material such that the flange is attached on the face of the sheet of material, and the sleeve extends outward from a second face of the sheet of material.
