A sliding door or window system includes a track. The track includes an outer housing; an inner housing within the outer housing; a guide body provided with the inner housing and configured to guide a sliding movement of a door or a window; and at least one adjustable body that is provided on the outer housing, at least partially within the inner housing, and fixed with respect to the inner housing in a vertical direction, the at least one adjustable body configured to change a height of the inner housing with respect to the outer housing by rotating, such as to change a height of the guide body.

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.

There is included an intermediate element including one or more, but not necessarily limited to, an L-shaped profiled portion configured to receive a part of a panel of a door or window, a pad configured to be fit into at least one frame part and comprising a support strip groove, and an intermediate element extended from the L-shaped portion to the pad.

An adjustable header having a first header piece and a second header piece, which are attachable to each other by a connector.

Improved sliding window or sliding door with a leaf with a leaf frame that is composed of leaf profiles which each comprise two half-shells which are thermally connected to each other by an intermediate thermal insulator, whereby in the leaf frame a rebate is provided for a panel which is supported by one or more glazing bead supports in the rebate and whereby the leaf frame is supported by one or more roller cassettes with rollers, wherein at least one glazing bead support comprises a feed-through section for transmitting the weight of the panel or a part thereof to at least one concerned roller cassette and that this feed-through section extends through a bottom leaf profile of the leaf frame up to a roller cassette.

The present application relates to an arrangement for reducing thermal energy loss through a sill assembly of the type used with a door or window. The sill assembly includes at least one sill member. The at least one sill member has a hollow region therein. The sill assembly further includes a baffle disposed within the at least one sill member. The baffle spans a length of the at least one sill member and divides the at least one sill member into a plurality of chambers thereby limiting interaction of warmer air and cooler air within the at least one sill member. The baffle reduces heat transfer through the hollow region via convection.

Provided is a tower of a wind turbine, having a hollow inner space and a door for opening and closing an aperture into the inner space, wherein the door is a sliding door, which is slidingly arranged on a tower aperture member attached to the tower, and which sliding door is at least partially sealed by a seal to the tower aperture member at least when the door is in the closed position.
