ABSTRACT:
The present invention provides spacer stock for making a spacer frame for a multi-sheet unit. The spacer stock includes a first supporting surface; a second supporting surface opposite to, and facing away from, the first supporting surface; a base surface between and connecting the first and second supporting surfaces, and wherein the first and second supporting surfaces and base surface are made of plastic and rate of moisture and/or gas movement through portions of the first and second supporting surfaces is greater than the rate of moisture and/or gas movement, respectively through the base surface.
