A back bedding glazing compound applicator assembly is disclosed. The back bedding glazing compound applicator assembly comprises a nozzle head that is fluidly connected to a back bedding glazing compound supply source and a stabilizer device for retaining a fixed vertical position of a viewing surface while back bedding glazing compound is being dispensed by the nozzle head. The nozzle head includes a back bedding glazing compound channel fluidly connected to a dispensing opening. The dispensing opening is positioned adjacent a bottom surface of the nozzle head.

System and method for glazing

A system for glazing a sash is disclosed. The system comprises at least two position assemblies, a back bedding glazing compound applicator assembly, and a stabilizer assembly. The position assemblies each include a position member defining a distal end and a housing. Each position member is selectively slidable between a stored position and an extended position; wherein the distal end of the positioner member is extend outwardly from the housing and contacts a glazing leg of the sash when the positioner member is moved into the extended position. The back bedding glazing compound applicator assembly is configured to move from a stored position to a dispensing position, wherein the back bedding glazing compound applicator assembly includes a nozzle head that is configured to fit within a gap defined between an interior surface of the sash and an outer edge of a viewing element disposed within an opening of the sash when the back bedding glazing compound applicator assembly is in the dispensing position and wherein the back bedding glazing compound applicator assembly is fluidly connected to a back bedding glazing compound supply source. The stabilizer assembly is configured to retain the viewing element in a fixed position with respect to the sash while back bedding glazing compound is being dispensed by nozzle head.

A method of glazing a sash is disclosed. The method begins by placing a sash on a glazing table, wherein the sash defines an opening therein and has a glazing leg extending into the opening in the sash. At least two positioner assemblies are actuated, each positioner assembly having a position member defining a distal end. Each position member is selectively slidable between a stored position and an extended position. When the positioner assemblies are actuated, each position member is moved into the extended position such that the distal end of the positioner member contacts the glazing leg of the sash. A viewing element is then inserted into the sash opening and into abutting contact with portions of the positioner members so as to create a gap between an interior surface of the sash and an outer edge of the viewing element. Once the viewing element is positioned, the positioner members are retracted. Next, a back bedding glazing compound applicator assembly is actuated to move from a stored position to a dispensing position. The back bedding glazing compound applicator includes a nozzle head that is configured to fit within the gap between the interior surface of the sash and the outer edge of the viewing element when in the dispensing position. Once positioned, back bedding glazing compound is dispensed between the glazing leg and the viewing element. Once dispensing is complete, the back bedding glazing compound applicator assembly is retracted.

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.

A grid simulating muntins is retained or secured by clips within a spacer frame between glass sheets. The clips include a spacer-engaging member having a platform, and upright walls bendable toward one another, and a grid-engaging member. The grid-engaging member is mounted on the platform, extends upward between and spaced from the upright walls, and is received into one of the ends of the elongated members of the grid. The platform and portions of the upright walls of the spacer-engaging member are positioned within the spacer frame such that the ends of the elongated members of the grid are below the sight line of the unit. The spacer-engaging member and the grid-engaging member can be a monolithic piece, or the grid-engaging member can be detachably secured to the platform of the spacer-engaging member.
