This present invention generally relates to the manufacture and application of a vented glazing system to existing glazed units or new glazing units. More particularly this invention relates to a method of glazing and a glazing system that will increase thermal performance and reduce condensation for existing glazed units.

A secondary window system installable within a primary window frame that includes a top horizontal member, a bottom horizontal member spaced from the top horizontal member, and first and second side members, the secondary window system including a top channel member attachable to and extending along at least a portion of the top horizontal member of the primary window frame, a secondary window frame comprising a header, a sill spaced from the header, first and second side jambs spaced from each other and extending from the header to the sill, and a secondary window opening defined by the secondary window frame, a top channel retainer engageable with the header of the secondary window frame, and at least one hanger engageable with the top channel member and the top channel retainer, wherein the secondary window frame is rotatably moveable relative to the primary window frame about the at least one hanger.

A composite sash and frame for windows and doors uses a sash assembly, a frame head, a frame sill and a frame jamb to thermally maximize structural integrity, prevent thermal transfer, and increase aesthetic appeal. The composite sash and frame for windows and doors uses a two-sided system. The first side is constructed from rigid durable materials that are designed to withstand corrosion and is positioned on the exterior surface of a building. The second side is constructed from aesthetically appealing thermally isolating materials and is positioned on the interior surface of the building. The sash assembly, the frame head, the frame sill, and the frame jamb are all constructed using this two-sided architecture, and are thus specifically designed to withstand corrosion and damage while satisfying the user's aesthetic requirements.

A main support frame is formed from sections of a plastic extrusion and has opposite side portions with peripheral recesses receiving an inner sash unit and outer sash unit each having a frame formed from sections of a plastic extrusion and supporting an insulated glass unit. Hinges support the dual sash units for pivotal movement between open and closed positions, and gear connected telescopic link members connect the main frame to the sash frames for simultaneous movement. A lock system includes a handle on the inner sash unit for moving straps with studs on the sash frames through a connector mechanism mounted on the main frame for simultaneously locking and releasing both sash units and for releasing only the inner sash unit. A screen and/or mini-blind can be supported between the sash units, and the window system with dual sash units may be constructed in various forms.

A configuration of tandem high efficiency primary windows is disclosed as both a structure and method to enhance the energy efficiency of windows. Each of the tandem windows is separately installed, respectively, on the exterior and interior of a building window opening. Each window may be separately operable for opening, closing, and cleaning. The interior window can include a cover, surrounding any part of the frame that protrudes into the interior space, the cover having an air gap for interior air to circulate and remove moisture from the interior surfaces of the interior window and its frame. The space between the windows is vented for removal of water vapor, if necessary, by a tube that extends from the space to the outside or to the cold side of the window opening, the tube having features that prevent the entry of outside into the space between the windows.

A construction profile, in particular for a window or door frame, includes: a) a polymeric core profile; b) a metallic side profile structurally attached to the polymeric core profile such that the polymeric core profile and the metallic side profile behave as a single structural entity. The construction profile defines a room side that in use faces an interior of a building, and an exterior side that in use faces the outdoors. The polymeric core profile includes side walls defining a cavity divided in multiple inner rooms separated by inner walls extending in a longitudinal direction of the construction profile. The metallic side profile is provided on a side wall of the polymeric core profile facing the interior, external of the polymeric core profile.

Extruded plastic profiles with integrated insulation, the method for extruding such products, and the windows and doors made with such plastic extrusions. The plastic extrusions may additionally include a low heat build-up capstock system comprising an acrylic cap and pigment system that is substantially IR transparent. The extruded plastic profiles with integrated insulation are recyclable using conventional plastic extrusion process and are fully weldable in conventional window and door manufacturing.

A sliding window assembly (35) including a window frame and at least two glass panes (38, 39). At least one of the glass panes (38, 39) slides within the frame between an open position and a closed position, wherein one of the edges of each pane overlaps to form overlapping edges (42, 43). First and second rails (44, 45) are connected to the overlapping edges (42, 43) and cooperate to form a seal between them in the closed position. Each rail (44, 45) is formed from a metal component (46) and a plastic component (51) that are formed separate from each other and are assembled in nesting connection. The seal in the overlap between the overlapping edges (42, 43) in the closed position of the panes (38, 39) is formed between the plastic components (51) of the first and second rails (44, 45). The metal components (51) of the first and second rails (44, 45) are spaced from contact with each other and extend to overlie outwardly facing surfaces of the first and second panes (38, 39).
