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 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 an adhesive comprising internal voids that create one or more drainage paths within said water pervious adhesive layer, said water pervious adhesive layer comprising a polymer-modified cementitious adhesive comprising from about 32 to about 70 weight percent of at least one cementitious material component, from about 5 to about 30 weight percent of a polymer component, from about 0.3 to about 32 weight percent of at least one aggregate component, and from 0 to about 30 weight percent water; and an exterior finish material applied to at least a portion of the exteriorly facing surface of said insulation layer.
