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 unit includes a fenestration frame with a first frame member, and a sash including a sash frame to support a glazing unit. The fenestration unit includes a channel defined in one of the first frame member and the sash frame that extends along a first axis. The fenestration unit includes a retainer base associated with the other of the first frame member and the sash frame that extends along the first axis. The fenestration unit includes a retainer removably coupled to the first frame member and the sash frame to removably retain the sash frame on the fenestration frame. The retainer has a first retainer arm, a second retainer arm and a third retainer arm. The third retainer arm is movably coupled to the channel and the first retainer arm is movably coupled to the retainer base.

A parallel sliding system, in particular deposit-sliding system, may include a leaf, in particular a window or door leaf, which can be displaced horizontally from a closed position, in which the leaf closes an opening, in particular a window opening or door opening, into a sliding position, in which the leaf can slide parallel to the opening into an open position exposing the opening, and at least one slide which, when the leaf is displaced horizontally from the sliding position back into the closed position, is displaced relative to the leaf in the vertical direction in order to close in a sealing manner at least one gap between the leaf and a horizontal spar of a frame profile which surrounds the leaf in the closed position.

A water penetration prevention system includes an insert for being positioned along a track for a window, the insert having a first engaging portion disposed on a first side of the insert and a second engaging portion disposed on a second side of the insert. The system also includes a seal engaging member disposed between the first engaging portion and the second engaging portion, the seal engaging member being selectively positionable between a first position that a second position. The seal engaging member, in the second position, applies a force on at least one of the first side of the insert and the second side of the insert that causes the at least one of the first side of the insert and the second side of the insert to sealingly engage a corresponding one of the window and a vertical wall of the track.

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.

The invention describes the new aluminum alloy window design to provide increased energy saving, water proof, wind proof and how to maximize the material during the manufacturing process. There are only six different aluminum alloy extrusion pieces to construct the main structure of this aluminum sliding window. The current aluminum sliding window sold in USA usually consist of at least eight main aluminum alloy extrusion pieces. With this new window design, the window manufacture will be able to save on labor, material and inventory throughout the manufacturing process. Please see FIG. 1 for detail.

The exterior frame and plain stile of the aluminum sliding window have three stopping points consisting with one special designed shark-gill shape rubber strip and two brush seals. See FIGS. 2 and 3 for detail cross section diagram of the aluminum sliding window exterior frame and plain stile. With this window design, the outside cold air will need to make six turns in order to flow into inside of house. The head and sill of the exterior window frame have thermal insulation dividers to provide waterproof, windproof and thermal insulation function of the main window section. Please see FIG. 4 for illustration of this function. The meeting stile of the interior window has interlock mechanism with double shark-gill shape rubber strips to provide vertical water/wind proof in addition to the thermal insulation function. See FIG. 5 for detail on the window meeting stile cross section diagram. With this new window design, the window will reduce the manufacture cost and provide better and energy efficient window to customers.

The present invention relates to a door guide frame of a detachable segment structure for sliding windows and doors, in which in order to improve heat insulating performance of the door guide frame, the door guide frame is divided into an outer body portion and an inner body portion and a thermal break is disposed therebetween, and even when a second pocket guide segment accommodated in the inner side surface of the inner body portion and a third pocket guide segment accommodated in the inner side surface of the outer body portion are separated from an upper cap region of an aluminum material and have a lower leg region formed of a thermal break material, a supporting means capable of providing a good supporting force for the lower leg region formed of such thermal break material is provided without affecting the heat insulating performance of the door guide frame.

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 fenestration unit including a first panel having a leading portion and a trailing portion, a second panel, and a frame including a first lateral member and a second lateral member. The first lateral member has a trolley space configured to slideably receive a trolley assembly. The trolley assembly includes a first trolley coupled to the leading portion of the first panel and a second trolley coupled to the trailing portion of the first panel. Each of the first and the second trolleys includes a guide pin slideably received in the leading and trailing tracks, respectively. The guide pins are configured to guide the first panel out of a coplanar relationship with the second panel when the first panel is slid to an opened position and guide the first panel into a coplanar relationship with the second panel when the first panel is slid to a closed position.

A fenestration wall assembly includes a fenestration frame extending along a perimeter of the fenestration wall assembly. The fenestration frame includes a socket core having a first module socket configured to interchangeably receive service modules therein, and a second module socket configured to interchangeably receive service modules therein. The interchangeably received service modules include at least first and second service modules. Each of the first and second modules includes respective first and second module profiles. A panel having a panel profile is surrounded by the fenestration frame. The panel profile is isolated from the first and second module profiles.
