Abstract
A moisture barrier system, comprising a barrier sheet adapted to be installed on a building having an interior wall structure and an exterior wall structure spaced apart from the interior wall structure to define a cavity there between.
Claims20
A method of installing a moisture barrier on a building having an interior wall and an exterior wall spaced apart from the interior wall to define a cavity therebetween, the method comprising
- applying a sealant to an exterior-facing surface of the interior wall in a line extending horizontally at least partially around the interior wall of the building,
- providing a plurality of barrier sheets,
- applying an upper section of the plurality of barrier sheets to the exterior-facing surface of the interior wall over the sealant,
- applying a lower section of the plurality of barrier sheets to the exterior wall,
- deforming the upper section of the plurality of barrier sheets to be parallel with the exterior-facing surface of the interior wall,
- deforming the lower section of the plurality of barrier sheets to be parallel with an upper surface of the exterior wall, wherein a medial section of the plurality of barrier sheets extend at a downwardly sloped angle from the upper section to the lower section,
- retaining the upper section of the plurality of barrier sheets to the interior wall with the sealant,
- retaining the lower section of the plurality of barrier sheets to the exterior wall between two layers of masonry included in the exterior wall of the building,
- adhering the plurality of barrier sheets to one another by adhering opposing ends of each of the plurality of barrier sheets together to provide a continuous seal dividing upper and lower cavity subsections around a perimeter of the building, and
- supporting the opposing ends of each of the plurality of barrier sheets with a joint support that is arranged to lie on an underside of the barrier sheets,
- wherein the joint support includes an upper strip corresponding to the upper section of the barrier sheets, a lower strip corresponding to the lower section of the barrier sheets, and a sloped strip corresponding with the medial section of the barrier sheets, and
- wherein the lower strip is formed to include an opening and mortar extends through the opening to mechanically join the joint support to the exterior wall of the building.

A moisture barrier system adapted to be installed on a building having an interior wall and an exterior wall spaced apart from the interior wall to define a cavity there between, the moisture barrier system comprising:
- a first barrier sheet including an interior reinforcement mesh and an outer polymeric layer encapsulating the interior reinforcement mesh,
- a second barrier sheet, wherein neighboring ends of the first barrier sheet and the second barrier sheet overlap, and
- a sheet support system configured to support and join the first barrier sheet and the second barrier sheet to the interior wall and the exterior wall, the sheet support system including a sealant coupled to an exterior-facing surface of the interior wall to lie between the exterior-facing surface and an upper section of the first barrier sheet and the second barrier sheet, a corner unit arranged to extend around a corner of the building and to lie beneath at least one of the first barrier sheet and the second barrier sheet at the corner, a surface fixing system configured to mount the upper section of the first barrier sheet and the second barrier sheet to the interior wall, the surface fixing system including an attachment strip and a plurality of fasteners that each extend through a corresponding opening formed in the attachment strip, through the upper section of the first barrier sheet and the second barrier sheet, and into the interior wall, and a joint support extending between and interconnecting the interior wall and the exterior wall and arranged to lie beneath the neighboring ends of the first barrier sheet and the second barrier sheet,
- wherein the joint support includes an upper strip corresponding to the upper section of the first and second barrier sheets, a lower strip corresponding to a lower section of the first and second barrier sheets, and a sloped strip corresponding with a medial section of the first and second barrier sheets, and
- wherein the lower strip of the joint support is formed to include an opening so that mortar extends through the opening to mechanically join the joint support to the exterior wall of the building.
