Title:
SPACER FOR PROVIDING DRAINAGE PASSAGEWAYS WITHIN BUILDING STRUCTURES
Document Type and Number:
WIPO Patent Application WO2003018930
Kind Code:
A3
Abstract:
A roll-form spacer product (12) providing air space and drainage passageways within a building structure. Preferably, the spacer product (12) is a corrugated web of material having undulating front and rear faces (14, 16) and serpentine-shaped longitudinally extending edges (22, 24). The faces (14, 16) include alternating arrays of grooves (20, 28) and ridges (18, 26) which extend perpendicular to the side edges (22, 26) and parallel to an axis (A) of a spiral roll of the spacer (12). Thus, when the spacer (12) is unrolled and applied to a building structure in a plurality of horizontally extending rows, the ridges (18, 26) and grooves (20, 28) are substantially vertically-disposed to form a plurality of unobstructed passageways for the drainage of moisture. Preferably, the web (12) is made of an openwork mat of randomly convoluted polymeric filaments, and thus, enables ready circulation of air.
