The present invention provides a spacer frame for making a multi-sheet unit. The frame includes a spacer stock member having a first end and a second end, and a corner key comprising a bendable elongated body having a first end in the first end of the spacer stock member, an opposite second end in the second end of the spacer stock member, and a cut out between the ends, the ends of the corner key bendable relative to one another to decrease the spacing of the cut out.
Abstract:
An integrated window sash includes a sash frame having a first sheet supporting surface, a second sheet supporting surface spaced from the first sheet supporting surface and a base between the first and second sheet supporting surfaces; a first sheet having a first major surface and an opposite second major surface with marginal edge portions of the first surface of the first sheet secured to the first sheet supporting surface; a second sheet having a first major surface, an opposite second major surface, and a predetermined peripheral configuration with marginal edge portions of the first surface of the second sheet secured to the second sheet supporting surface, wherein the first major surface of the second sheet faces and is spaced from the second major surface of the first sheet to provide a compartment therebetween, and a desiccating medium carried on the base of the sash frame and communicating with the compartment, the base and the desiccating medium defining 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.
Abstract:
An integrated window sash includes a sash frame having a first sheet supporting surface, a second sheet supporting surface spaced from the first sheet supporting surface, and a base between the first and second sheet supporting surfaces, the base defining an opening; a first sheet having a first major surface and an opposite second major surface with marginal edge portions of the first surface of the first sheet secured to the first sheet supporting surface, the first sheet sized to pass through the opening toward the first sheet supporting surface; a second sheet having a first major surface and an opposite second major surface with marginal edge portions of the first surface of the second sheet secured to the second sheet supporting surface, the second sheet sized to be larger than the opening, wherein the first major surface of the second sheet faces the second major surface of the first sheet and is spaced therefrom to provide a compartment between the sheets; and a retainer mounted on the base between the sheets and having a first end portion engaging surface portions of the second surface of the first sheet and an opposite second end portion secured to the base.
Abstract:
A corner key for joining ends of spacer sections to form a corner of a spacer frame of a multi-sheet unit includes an elongated body having a first end and an opposite second end and a cut out between the ends of the body. The body is bendable to decrease spacing of the cut out to form a corner of the spacer frame.
Abstract:
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.
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.
Abstract:
The present invention provides a multi-sheet unit with a spacer frame having at least three sides, at least three corners, a first sheet supporting surface and an opposite second sheet supporting surface. The spacer frame includes a spacer stock member having a first end, an opposite second end, the at least three sides and at least two corners of the at least three corners; a corner key comprising a bendable elongated body having a first end in the first end of the spacer stock member, an opposite second end in the second end of the spacer stock member to provide one of the corners of the at least three corners of the spacer frame, and a cut out between the ends of the corner key, the ends of the corner key bendable relative to one another to decrease the spacing of the cut out; a first sheet secured to the first sheet supporting surface by a first moisture and/or gas impervious layer, and a second sheet secured to the second sheet supporting surface by a second moisture and/or gas impervious layer.
Abstract:
A method for forming a coated substrate is disclosed. The method comprises depositing an undercoating layer and depositing a functional coating comprising a material which can be present in more than one crystal structure over the undercoating layer, wherein there is a critical deposition thickness at which the functional coating transforms from a first polycrystalline film made up predominantly of the material having a first crystal structure to a second polycrystalline film made up predominantly of the same material having a second crystal structure.
Abstract:
An insulating unit includes a first and a second sheet, each of the sheets having a first major surface and an opposite second major surface; an arrangement to position the first and second sheets in spaced relation to one another to provide a compartment between the sheets, the second major surface of the first sheet and the first major surface of the second sheet facing the compartment; a lattice made of muntin bars in the compartment, the lattice having end portions adjacent to and spaced from the arrangement; and a retainer clip having a first end portion connected to an end portion of the lattice and the opposite second end portion having a compressible base, the compressible base in surface contact with the second major surface of the first sheet and the first major surface of the second sheet to retain the lattice in position between the sheets.
