A vapour barrier pan for use in building structures is provided. The pan is shaped to fit into the joist pocket located between subsequent joists of buildings. The pan central body comprises a top edge, two sides joined to the top edge generally perpendicularly, and a bottom edge joined to the two sides and parallel to the top edge. A centre crease is situated in between the two sides and extends from the top edge to the bottom edge. The centre crease instills flexibility into the pan body allowing it to be bent in order to fit into joist pockets of varying sizes. Alternatively, the pan can be cut along the centre crease separating it into two portions that can be overlapped to cover small joist pockets. The top edge and sides comprise flanges that extend outwardly in the same direction, with the flange for the top edge having a slit corresponding to the centre crease. Below the central body is a tab that can be situated under or over insulation installed in between wall studs under the joist pocket. |
