Disclosed herein is a sill configuration of a framework assembly. The sill configuration includes a shoulder, defining a plug supporting surface. The sill configuration is configured for co-operation with the movable sash configuration and the fixed sash configuration so that while a movable sash configuration and a fixed sash configuration are mounted to the sill configuration: (i) the movable sash configuration is slidable, relative to the sill configuration, and (ii) the movable sash configuration, the fixed sash configuration, and the sill configuration are co-operatively disposed so that a space is defined between the movable sash configuration, the fixed sash configuration, and the sill configuration, and (iii) the plug supporting surface of the shoulder is configured for supporting a plug for disposition within the space. While the framework assembly is mounted within the opening of the building construction, the plug-supporting surface is elevated relative to the base.

A fenestration system may comprise a closure element, such as a door or window. The closure element is movable relative to a frame between open and closed positions. The frame surrounds a fenestration opening, such as a doorway. The fenestration system may also comprise a carrier mounted to the closure element and movable relative to the closure element between extended and retracted positions. A weather strip is attached to the carrier and arranged to contact the frame in the extended position of the carrier. One or more retraction magnets may be arranged to exert a first magnetic force on the carrier to move the carrier into the retracted position in the open position of the closure element. One or more extension magnets may be arranged to exert a second magnetic force on the carrier to move the carrier into the extended position in the closed position of the closure element.

The present invention relates to a heat insulation and support structure between a moving window (sliding window) and a fixed window constituting a sliding window system, or between a moving window and another moving window. More particularly, the present invention relates to a window chassis insulating structure and a glass panel supporting (mounting) structure including technical improvements in a center bar portion in which a window chassis of a movable window and a fixed window (or other movable window) overlap each other when a sliding window of a two-side supporting frame window having a two-sided supporting frame for supporting only both sides of a glass window constituting a sliding window system, is closed.

The present invention relates to an installation structure of an elastic gasket attached and installed as a sealing member to a moving window glass supporting insulation bracket in a sliding window having a two-sided supporting frame window chassis, and more specifically, it relates to an installation structure of a sealing member (e.g. an elastic gasket) that is installed to provide a sealing function between a glass supporting insulation bracket that directly supports a glass panel of the moving window from the top or bottom and a window frame provided with a sliding rail, when opening and closing the sliding window having only two-sided supporting frame that support both sides of the glass window constituting the sliding window.

Exemplary implementations of a thermally-efficient slidable fenestration assembly are glass window systems or glass door systems having one or more sliding glass panels. The fenestration assemblies are adapted to be mounted in an architectural structure such as a building or house. Accessory channels in the fenestration framework may be provided to facilitate nail-fin, retro-fit or screen adaptors as means to attach the assembly to the surrounding architecture. Stiles, tracks and rails of the assembly are specifically configured to reduce heat transfer across the fenestration assembly, while simultaneously maintaining the structural integrity and durability of the overall assembly. Certain stile, track and rail components may comprise materials of relatively low conductivities. Preferred stile configurations include interlock elements arranged to reduce the assembly's vulnerability to tampering from a position outside of the fenestration.

A fenestration assembly includes a glazing unit includes a pane spacer between exterior and interior panes proximate glazing unit edges. A fenestration frame is coupled around the glazing unit and includes a frame core extending around the glazing unit. The frame core includes a unitary core wall including a composite material that is hollow and extends continuously from a core interior face to a core exterior face. A metal glazing cap is coupled with the frame core. The metal glazing cap having a cap end indirectly engaged with the glazing unit along the interior pane, and the cap end is remote from the pane spacer. Each of the core exterior face, the pane spacer and the metal glazing cap are thermally isolated from each other with the frame core including the unitary core wall.

A frame assembly, for use in window and door applications configured to retain a panel, comprising a frame with a cover assembly and a support assembly having a track assembly, and a sill assembly and a header assembly both interconnected to a securing surface. The cover assembly is interconnected to the support assembly. The sill assembly comprises a roller member disposed in supporting relation to the track assembly, and the header assembly is disposed in supporting relation to the support assembly so that the frame is movable relative to both the header assembly and the sill assembly. At least a portion of the frame comprises a predetermined thickness and a predetermined width. The predetermined thickness is substantially less than the predetermined width so that both cooperatively and concurrently enhance viewing through the panel and the frame's stability.

There is provided a sash apparatus for securing in a window or a door, and a methods making same. The sash apparatus comprises a frame with multiple segments securable to the window or door, where each of the segments has an internal passage therein. The multiple segments are arranged and coupled together at non-straight angles to form the frame, with the internal passages within the segments in fluid communication with one another. The sash apparatus also includes a bonding fill at least partially filling the internal passages within the frame to hold the multiple segments together.

A thermally enhanced extrudate includes a channel, a first wall, and a second wall. The channel extends along a longitudinal axis from a first end to a second end of the thermally enhanced extrudate and is shaped to receive glass or a frame. The second wall is spaced from the first wall. The first wall and the second wall partially enclose a thermal break extending along the longitudinal axis. The thermal break has a first width defined between the first wall and the second wall at an upper end of the thermal break and a second width defined between the first wall and the second wall at a lower end of the thermal break. The thermally enhanced extrudate further includes a solid insulation material in the thermal break between the first and second walls and formed by curing a flowable material.

Provided is a window system including a first window that extends in a first direction, and that partially overlaps a second window in the first direction. The second window extends in the first direction, and is offset from the first window in a second direction that is orthogonal to the first direction. The window system includes a connector that is configured to connect the first window and the second window, and that is disposed in an area between the first window and the second window in the second direction and where the first window partially overlaps the second window in the first direction.
