Abstract:
1. A method of making an integrated window sash, comprising: providing a sash frame having a first sheet supporting surface, a second sheet supporting surface, a ledge connected to the second sheet supporting surface and extending away from the second sheet supporting surface, a base extending from the first sheet supporting surface toward the second sheet supporting surface, and a layer of a low gas and moisture permeability material on the base and facing open area defined by the sash frame; applying a first layer of an adhesive sealant having a low gas and moisture permeability on the first sheet supporting surface; applying a second 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 over the surface of the base; moving a first sheet having a first major surface, an opposite second major surface and a peripheral edge connecting the first and the second major surfaces into the spacer frame against the first layer of the adhesive sealant to secure the first surface of the first sheet against the first sheet supporting surface, wherein as the first sheet is moved over the layer of the moisture pervious matrix toward the first layer of the adhesive sealant, the peripheral edge of the first sheet moves over, is spaced from, and out of contact with, the layer of the moisture perilous matrix; providing a flexible sheet retainer having a first end portion and a second end portion; positioning the first end portion of the sheet retainer in facing relationship to the second surface of the first sheet; providing a second sheet having a first major surface and an opposite second major surface and moving the first surface of the second sheet against the second end portion of the sheet retainer to move the first end portion of the sheet retainer against the second surface of the first sheet to compress the sheet retainer between the second surface of the first sheet and the first surface of the second sheet, and to move the first surface of the second sheet against the second layer to secure the first surface of the second sheet against the second sheet supporting surface, wherein the first surface of the second sheet is spaced from, and in facing relationship to, the second surface of the first sheet to provide a compartment therebetween, and the desiccant is in communication with the compartment, and wherein after the practice of moving the second sheet, the first end portion of the sheet retainer is biased against at least the second surface of the first sheet to move the first sheet toward the first sheet supporting surface, and securing a preformed holding component to the ledge of the sash frame, wherein the holding component engages, and is continuous, around marginal edges of the second surface of the second sheet, wherein the holding component frames the second sheet.
