Abstract
An integrated window sash includes a sash frame having a base between first and second sheet supporting surfaces and first and second sheets each having a first surface and an opposite second surface. The marginal edge portions of the first surface of the first sheet are secured to the first supporting surface, and marginal edge portions of the first surface of the second sheet are secured to the second supporting surface. The first surface of the second sheet faces and is spaced from the second surface of the first sheet to provide a compartment therebetween. A desiccating medium carried in a groove, or on the base communicates with the compartment, and the base and the desiccating medium define an interior opening in the sash frame, wherein the first sheet is sized to pass through the interior opening to the first sheet supporting surface without contacting the desiccating medium.
