Weather barrier for a building penetration

摘要

A weather barrier for a building penetration. The building penetration has an opening in a wall of the building and a utility in the opening. The weather barrier has a sheet of material that is flexible and water resistant and having an outer perimeter and a resilient seal attached to the sheet of material within the outer perimeter. The sheet of material extends out around the resilient seal. The resilient seal is sized to resiliently clamp about the utility such that the resilient seal seals against and is supported by the utility when installed.

1. 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 weather barrier comprising:
a sheet of non-elastic material, the non-elastic material being flexible, water resistant, and air permeable, 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 sheet of elastomeric material sealably attached to the sheet of non-elastic material at the inner perimeter, the sheet of elastomeric material extending inward from the inner perimeter and defining a central opening that is smaller than the outer diameter of the utility, wherein, 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 the plane of the sheet of non-elastic material.
