A roll-form spacer product providing air space and drainage passageways within a building structure. Preferably, the spacer product is a corrugated web of material having undulating front and rear faces and serpentine-shaped longitudinally extending edges. The faces include alternating arrays of grooves and ridges which extend perpendicular to the side edges and parallel to an axis of a spiral roll of the spacer. Thus, when the spacer is unrolled and applied to a building structure in a plurality of horizontally extending rows, the ridges and grooves are substantially vertically-disposed to form a plurality of unobstructed passageways for the drainage of moisture. Preferably, the web is made of an openwork mat of randomly convoluted polymeric filaments, and thus, enables ready circulation of air.
