The invention relates generally to the field of construction, and in particular to the use of a glass unit instead of the opening sashes of windows and doors, without using sash profiles into which conventional insulating glass units or insulating glass units with one protruding outer pane are usually fixed. The adaptive insulating glass unit is intended for use on windows and doors pre-installed in an opening or facade, as well as for use in the production of new windows and doors, which in turn are used for glazing door and window openings (fixed glazing or one with a sash opening inward, sideways, outward or upward off the frame) in residential buildings, in public and industrial buildings, display structures. The technical result of the invention is a quicker and more accurate assembly of multi-chambered insulating glass units with glued-in profiles, increased light transmission, thermal insulation and soundproofing properties of existing window and door systems without the need to reconfigure production processes, without the need to readjust and replace equipment used in the production of windows, as well as increased light transmission, thermal insulation and soundproofing properties of window and door systems pre-installed in the openings and facades of buildings without the need to reinstall them. The adaptive insulating glass unit designed to be used instead of the opening sashes of windows and doors, without the use of sash profiles into which conventional insulating glass units or insulating glass units with one protruding outer pane are usually fixed, offers new prospects for the design of new window and door systems. The adaptive insulating glass unit contains two outer panes and at least one inner pane, spaced from each other by spacer frames placed between the panes. Moreover, the outer panes are always larger than the inner ones, and between them there is a profile inserted all the way to all the inner panes and simultaneously to one of the outer panes and glued to said outer pane by means of hard glue with additional fixation of the glued profile to another outer pane through the aid of a spacer element, with the gap formed between the profile and the outer pane to which the profile is not glued by means of hard glue filled with elastic glue and sealant, with the outer part of the profile adapted to fixing fittings and seals, which adapt the adaptive insulating glass unit to specific window systems.

This disclosure provides spacers for smart windows. In one aspect, a window assembly includes a first substantially transparent substrate having an optically switchable device on a surface of the first substrate. The optically switchable device includes electrodes. A first electrode of the electrodes has a length about the length of a side of the optically switchable device. The window assembly further includes a second substantially transparent substrate a metal spacer between the first and the second substrates. The metal spacer has a substantially rectangular cross section, with one side of the metal spacer including a recess configured to accommodate the length of the first electrode such that there is no contact between the first electrode and the metal spacer. A primary seal material bonds the first substrate to the metal spacer and bonds the second substrate to the metal spacer.

A privacy glazing structure may include an electrically controllable optically active material, such as a liquid crystal material, sandwiched between a flexible substrate and a rigid substrate. The flexible substrate and the rigid substrate may each have a conductive layer deposited on the surface facing the optically active material. The flexible substrate may be bonded about its perimeter to the rigid substrate and may be sufficiently flexible to conform to non-planarity of the rigid substrate. As a result, the flexible substrate may adopt the surface contour of the rigid substrate to maintain a uniform thickness of optically active material between the flexible substrate and the rigid substrate.
