Abstract
A roll-form spacer product providing an air space and drainage passageways within a building structure. Preferably, the spacer product is a thermoplasic web of material having hollow spacer elements formed integrally thereon. A first set of spacer elements projects outwardly from one face of the web and a second set of spacer elements projects from the other face of the web. The first and second sets of spacer elements are offset, project in opposite directions, and create air space and drainage passageways along each face. Thus, in a wall or roof construction, air, vapor and water are provided with exit paths extending along both the inner sheathing member and the outer building material. In addition, the web can also be provided with apertures for creating transverse paths therethrough.
