Exterior finish system

摘要

Disclosed is an exterior finish system for building structures that includes a water pervious adhesive for securing an insulation layer to a water resistive barrier applied to a building wall substrate. Also disclosed is a building structure such as a building column or wall that includes the finish system and a method of using the finish system to assemble a building structure such as a column or wall.

主权项

1. A building wall comprising:
a building wall substrate; a water resistive barrier layer applied to a portion of said building wall substrate; an insulation layer having opposite interiorly and exteriorly facing surfaces; a water pervious adhesive layer disposed between said water resistive barrier layer and said insulation layer adhering said insulation layer to said building wall substrate, said water pervious adhesive layer comprising a water pervious adhesive comprising internal voids that create one or more drainage paths within said water pervious adhesive layer, wherein said water pervious adhesive comprises a polymeric adhesive comprising from about 40 to about 90 weight percent of a polymer component, and from about 0.2 to about 45 weight percent of at least one aggregate component; and an exterior finish material applied to at least a portion of the exteriorly facing surface of said insulation layer.
