Vertical seals for use with exterior wall panel assemblies

A vertical seal for use with and to be positioned between two adjacent exterior wall insulated panels and sealant, comprising:

• opposed vertical side walls being resiliently deformable;
• at least two vertical end walls extending between the opposed vertical side walls, being resiliently deformable and each having a bend therein;
• a plurality of ribs extending outwardly from and longitudinally along each vertical side wall of the opposed vertical side walls such that, for each said vertical side wall, the plurality of ribs defines a faying area between the vertical side wall and a corresponding adjacent exterior wall insulated panel of the two adjacent exterior wall insulated panels, and the faying area is configured to receive sealant for affixing the vertical seal to the corresponding adjacent exterior wall panel, wherein a width of the faying area is defined by the plurality of ribs, and a faying area side of each rib of the plurality of ribs is orthogonal to the vertical side wall such that the faying area is an elongate rectangle in cross section;
• and
• wherein the opposed vertical side walls and the at least two vertical end walls define at least one cavity and wherein the bend in the vertical end walls facilitates movement of the opposed vertical side walls relative to each other.
