Abstract: The specification discloses a window or door, and glazing assemblies therefor, wherein the glazing assemblies include a first pane of glass with an exterior surface coated with a smooth, hardened silica-containing coating, and an opposite surface coated with at least one layer of a low emissivity coating. In one embodiment, a second pane of glass is joined to and spaced from the first pane of glass by a polymeric spacer. In a second embodiment, a third pane of glass is laminated to the second pane, and in a third embodiment, a third pane of glass coated on its interior surface with a low emissivity coating is joined to and spaced from the second pane by a polymeric spacer.

Abstract: A window latch assembly for locking first and second windows together includes a cover member coupled to the first window, and a handle pivotably coupled to the cover member. A lock member is fixedly coupled to the handle and has a lock portion adapted to protrude beyond a planar extent of the cover into a locked position, wherein the lock portion engages a lock keeper coupled to the second window, and an unlocked position, wherein the lock keeper is retracted inside the cover member. A mechanical finger is movable between a first position allowing the lock portion to be moved from the unlocked position to the locked position, and a second position preventing the lock portion from being moved from the unlocked position to the locked position, thereby preventing damage of the first and second windows.

Abstract: A latch assembly for double hung windows also permits each of the sashes to be tilted inwardly with respect to the window frame assembly. The window latch assembly includes a keeper which is recessed within a lower rail of the upper window sash, and a latch which is recessed in the upper rail of the lower window sash and positioned such that the latch and the keeper are selectively engaged upon rotation of a sweeper cam. The sweeper cam also engages a slide translatable between a first position engaging one of the side rails of the window frame assembly, and a second position, retracted within the lower window sash and release the upper edge of the window sash from the window frame assembly.

Abstract: An insulated window panel assembly for use in window and door assemblies having an improved insulating spacer between the window panes comprising the panel assembly. At least two panes of glass or other panel material are interconnected in parallel, spaced relationship by a spacer assembly. The spacer assembly is preferably a single length of tubing, generally rectangular in shape, having an outer wall of a first width interconnected to an inner wall of less width by generally concave sidewalls. The sidewalls also contain a bead of sealer material configured to seal with the adjacent window panes. A secondary seal is deposited on the outer wall and overlaps the sidewalls to also form a seal with the window panes. The spacer assembly is preferably one piece, bent to conform to the overall shape of the window panes wherein a first end of the spacer is connected to the opposite end. Folds may be made in the spacer along a crimp line formed in the inner wall to accommodate angular window pane configurations.

Abstract: An improved insulating spacer assembly for reducing heat transfer between panes of an insulated glazing unit comprises an extruded or roll-formed hollow metal spacer together with thermal breaks and primary sealant. The spacer and thermal breaks are preferably coextruded together, with the thermal breaks being extruded along the upper third portion of the spacer sidewalls, lengthwise along the spacer sidewall. The primary sealant is extruded along the middle third of the spacer sidewalls, parallel to and in cohering relationship to the thermal breaks. The invention also provides insulated glazing units wherein the spacer assembly is sandwiched between two glass panes to provide an exterior channel which is filled with a secondary sealant composition which also covers the exposed edges of the glass panes.

Abstract: An entry door system constructed of panels having a metal skin filled with insulating rigid foam core and having a unique wood facing and whereby the system has exceptional insulating qualities while projecting the beauty of a wood door. The system includes door and side panel components of substantially the same construction, except for the size, and provides for a versatile arrangement of panel components which in different selected combinations can be secured together into a single unit ready to be installed. The wood facing of the core filled panels includes wood stile and rail facing pieces and one or more raised panel subassemblies comprising a base panel to which is secured a raised panel with decorative wooden beads located at their perimeters which creates a wood picture frame look on the outer surfaces of the panels.
