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 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 sill track for sliding panels such as doors or windows in a door jamb or window jamb. The sill track mounts flush to the surrounding floors and has an integrated drainage system for preventing water from penetrating the sill track. The sill track comprises a base having walls to support flooring, a panel track for receiving a guide of a panel, such as wheels of a sliding glass door, and a weep channel wall forming a weep channel for draining water to below a top surface of the sill track. The walls of the base, the panel track and the weep channel wall are configured such that the flooring installed on the sill track, the panel track and the top of the weep channel wall are all flush with the surrounding flooring on the interior and exterior of the sill track.

This invention is directed toward a window for a garage door panel, where the window has an interior frame and an exterior frame. Both the interior and exterior frame have straight members that are secured to each other through the parts of the garage door that surround the opening with screws and screw receptacles. Connecting the frame members are corner braces, than come in a variety of designs, with some being invisible after installation and others forming a decorative corner to the window.

There is provided a kit of parts configurable for assembly within a window assembly, that defines a window opening, and includes a frame and a sash, wherein the sash is slidably mounted relative to the frame for slidable movement relative to the frame from a first position to a second position, wherein the kit comprises a frame member of the above-described frame, a sash member of the above-described sash; wherein: the frame member defines a retainer; and the frame, the retainer, and the sash are co-operatively configured such that, while the sash is disposed relative to the frame in the first position, the retainer is interfering with movement of the sash member in an inwardly direction, and while the sash is disposed relative to the frame in the second position, there is an absence of interference to movement of the sash member in the inwardly direction. There is also provided a window construction obtainable from assembly of at least the parts of the kit of parts.

A motorized window with one or more motors and a frame with a slidable segment is disclosed. A drive system with gears, transmission or worm drive engage with a gear track mounted to the frame or slidable segment. Rotating a first gear in a first rotational direction causes the first gear to pull the slidable segment in a first linear direction. Rotating the first gear in a second rotational direction causes the first gear to pull the slidable segment in a second linear direction. Preferably, a controller controls the operation of the motors. Sensors inform the controller, and user input via a mobile device enables both direct user control and programming of the controller.

Various aspects of the disclosure relate to modular sill systems for sliding panel doors and windows, collectively sliding fenestration units. In various examples, modular sill systems include multiple separate and distinct base components that provide tracks on which one or more panels are able to slide.

A horizontally sliding window can block a draft, rainwater, dust, and noise from being introduced through a gap between a window casing and a window while the window is closed, thereby improving indoor heat insulating and soundproof functions of the window. A horizontally sliding window includes a square frame-shaped window casing having a transverse frame and a longitudinal frame assembled therein and a window disposed on an inner side of the window casing. Moving frames are respectively interposed between the transverse frame and an upper end portion of the window and between the transverse frame and a lower end portion of the window, each including first and second cover members extending from opposite sides thereof to cover indoor and outdoor sides of the transverse frame, respectively, and having a roller rotatably coupled between the first and second cover members so as to operate in contact with the transverse frame.

A trim assembly securable in a window frame includes a track on which a sliding window is supportable, a latch insert including a plurality of latch openings, and a latch mechanism securable to the sliding window adjacent the latch insert. The latch mechanism is displaceable between an extended position and a retracted position and includes a lever connected with a latch tab. In the extended position, the latch tab is positioned in a selected one of the latch openings. The latch mechanism is biased toward the extended position. The spacing of the latch openings provides for essentially infinite open/close positions.
