Abstract
A method for making a compartmentalized sealant strip and barrier assembly 10 has the steps of co-extruding a barrier strip 9 of non-sealant elastomeric material with a plurality of projecting linear extending walls 9c and a sealant strip 11 wherein the sealant strip 11 is formed on one side of the barrier strip 9 filling the space between the plurality of projecting walls 9c to form a plurality of linearly extending rows of sealant 11 across the transverse width of the co-extrusion to form the compartmentalized sealant strip and barrier assembly 10.
