Wall system with vapor barrier securement

摘要

A system for assembling a pre-engineered building with a monolithic vapor retarder to control the formation of condensation on the walls. The system allows for numerous different combinations of insulation thickness, different kinds of walls, inside vapor retarders in different rigid panels, different facings or membranes. The system further provides for finished inside surfaces with high thermal quality.

1. A method to seal the joint lines of a vapor retarding barrier at the structural column lines of a pre-engineered building, the method comprising:
installing a plurality of structural building columns, each of the building columns including an outer flange and an upper element for securing the roof beam thereto; selecting a horizontally extending girt of a preferred width for subsequent attachment to the outer flange of the columns; offsetting a wall line of the building away from the structural columns by a distance roughly consistent with the span of the horizontally extending girt; attaching a trim plate with a first and second side as well as an interior and an exterior face to the outer flange of each structural column, the trim plate first and second sides overhanging the column outer flange; securing the horizontally extending girt over the trim plate and to the outer flange of the structural columns; positioning a first blanket of insulation atop the girt; positioning a second blanket of insulation adjacent the first blanket, the second blanket having at least one horizontally extending depression therein aligned with the at least one horizontally extending girt; securing at least one horizontally extending spacer block to an exterior wall panel, wherein the spacer block is positioned for receipt into the at least one horizontally extending depression; securing the exterior wall and spacer blocks to the girt; and securing an interior vapor barrier to both the first and second overhanging sides of the trim plate thereby eliminating any direct metal pathway between the interior and the exterior of the walls of the pre-engineered building.
