Modified foam wall structures with high racking strength and methods for their manufacture

A method for modifying a foam wall structure comprising depositing a high solids-containing chemically-curing polymeric structural adhesive composition into at least one of (A) an aperture located within a foam layer, and (B) an aperture located between the foam layer and a frame member, wherein the foam wall structure comprises:

• (a) frame members comprising:
• (i) a first member;
• (ii) a second member spaced apart from the first member;
• and
• (iii) connecting members extending between the first member and the second member, wherein the first member, the second member, and the connecting members each comprise a front surface and a rear surface that form a front frame surface and a rear frame surface;
• (b) a foam panel attached to the front frame surface, wherein:
• (i) the foam panel overlies the front frame surface;
• and
• (ii) the foam panel, the first member, the second member, and the connecting members define a cavity;
• and
• (c) the foam layer disposed within the cavity and adhered to the foam panel.
