The present invention relates to a thermal insulation structure of a door frame in which a moving window (sliding window) constituting a sliding window system is installed, and more particularly, a two-side supporting frame window supporting both sides of a glass window constituting a sliding window system, more particularly, relates to an insulating structure in a side section of a door frame into which the side portion of the sliding window that is moved when closing the sliding window of the supporting frame window type is pocketed, that is, the insulating structure of the side section of the door frame.

A frame system for a door or window is constituted by at least one fixed frame (1) and at least one movable sash (3) mounted in the fixed frame and having a central post (5) and a handle (4). The locking system (6) for the sash (3) is integrated in the aluminum profiles of the fixed frame (1). The sash (3) has no visible aluminum profiles next to the floor and next to the ceiling. The thickness of the visible aluminum of the post and of the handle ranges from 1 mm to 5 mm and the central post (5) and the handle (4) can be mounted to either side of the movable sash without modification.

A sill assembly that can include a sill and one or more threshold inserts. The threshold inserts can cover cavities within the sill. The sill assembly can optionally include a subsill, which can be a separate from or part of the sill. The subsill can include subsill cavities aligned over the sill cavities to form vertically-stacked pressure chambers. These vertically-stacked pressure chambers can include vertically-stacked pressure chambers positioned within the interior of the building, and vertically-stacked pressure chambers positioned within the exterior of the building. The sill assembly is so structured that different door types, such as swing doors, pivot doors, folding doors and/or sliding doors can be accommodated using the same sill and subsill by simply changing the threshold inserts. The sill assembly can have a minimal rise above the floor surface to meet regulatory requirements such as the Americans with Disabilities Act (ADA).

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 fenestration unit includes a first glass unit, a first panel frame, a second glass unit, a second panel frame, a sill flashing, and a frame. The frame includes a header, jambs, and a frame sill including a first track and a second track. The first panel frame and the first glass unit are slidable along the first track when positioned in the frame. The second panel frame and the second glass unit are slidable along the second track when positioned in the frame. The sill flashing includes a base extending under the first and second tracks and a wall extending upward from the base to inhibit moisture intrusion through the fenestration unit. The frame sill is removable from the frame without disassembling the sill flashing, the jambs, and the header.

A semi-invisible combination of thermal insulating profiles of the lower part of sliding doors and windows which allows the unhindered passage of people and objects above the semi-invisible combination. The interior and exterior floor has co-planarity and uniformity while the invention permits unhindered passage of people and objects, is accessible by people with walking disabilities, has narrow width grooves, has a classy profile design, has high levels of waterproofing for the non-visible parts as well as high waterproofing against normal weather conditions.

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 se cond walls and formed by curing a flowable material.
