A method of making an integrated window sash includes providing a sash frame having a first sheet supporting surface, a second sheet supporting surface, and a base extending from the first sheet supporting surface to toward the second sheet supporting surface; applying a layer of an adhesive sealant having a low gas and moisture permeability on the first sheet supporting surface; applying a layer of an adhesive sealant having a low gas and moisture permeability on the second sheet supporting surface; applying a layer of a moisture pervious matrix having a desiccant therein on the base; moving a first sheet having a first major surface and an opposite second major surface into the spacer frame over and spaced from the matrix to move the first major surface of the first sheet against the first layer, and moving a second sheet having a first major surface and an opposite major surface toward the second layer to move the first major surface of the second sheet against the second layer, wherein the first surface of the second sheet is spaced from the second surface of the first sheet to provide a compartment therebetween and the desiccant is in communication with the compartment.
