Adhesive having structural integrity and insulative properties

An article comprising a first substrate, a second substrate, and an adhesive composition interposed between the two substrates comprising:

• (a) about 50 to about 99.9 weight percent, on a dry weight basis, of an emulsion-based polymer selected from the group consisting of vinyl acetate ethylene dispersion, polyvinyl acetate, polyvinyl acetate polyvinyl alcohol, dextrin stabilized polyvinyl acetate, polyvinyl acetate copolymers, vinyl acetate-ethylene copolymers, vinylacrylic, styrene acrylic, acrylic, styrene butyl rubber, polyurethane and mixtures thereof;
• (b) about 0.1 to about 10 weight percent, on a dry weight basis, of a plurality of expandable microspheres;
• (c) water;
• and
• (d) optionally, plasticizer and/or preservative;
• wherein the volume of the microspheres is greater than 200% in the dry adhesive upon expanding the microsphere.
