Abstract
A layered sheet construction contains at least one gas permeable, liquid water impermeable layer, and a gas delivery layer formed of a corrugated sheet proximate the gas permeable, water impermeable layer. The corrugated sheet has corrugations that form flow channels through which gas can be conveyed to the gas permeable layer. One embodiment of the layered sheet construction includes a gas permeable, liquid water impermeable layer having a surface energy that is below 20 dynes per centimeter.
