ADDITIONAL HEAT-SAVING DETACHABLE WINDOW LINING Russian patent published in 2014 - IPC E06B7/00 

FIELD: construction.

SUBSTANCE: invention relates to construction and is intended for additional heat insulation of already installed single or double translucent part of a window structure. The technical result is achieved by application of an additional detachable lining attached to a translucent material (glass) of the already available window structure. The additional detachable lining is a translucent material (in this structure a glass or a polycarbonate sheet), to the surface of which a gasket is attached in a non-detachable manner to the perimeter, made of the elastic material (for instance, silicon) and spacers. The additional detachable pad is tightly applied to glass of the existing window frame, and in the gap between glasses there is vacuum pulled, thus providing for fixation of the detachable lining. Vacuum is pulled by an external device by pumping of air via a valve installed on the glass of the additional detachable lining, thus, a vacuum multiple glass pane is created, including glass of the additional detachable lining of the glass being a structural element of the already existing window frame. In order to create identical stress in the entire surface of the multiple glass pane produced in this manner, the surface of the additional lining glass equipped with a gasket and facing the surface of the glass of the existing frame, is equipped with evenly installed supporting points (spacers). At the same time in the initial condition (before pulling vacuum in the interval between glasses) the height of the gasket must be more than the height of the spacer. When vacuum is pulled, the elastic material of the gasket is compressed, being pressed to the window frame glass, and becomes equal to the height of spacers, providing for tightness along the glass contour. To remove the additional lining early, it is necessary to lift an edge of the valve opening a hole 6 and bleed air from glass-to-glass space. For reliability it is permitted to coat the surface of the gasket with silicon or other lubricant. To prevent air leak, transparent scotch tape may be adhered on top of the valve.

EFFECT: increased extent of heat insulation and noise insulation of a translucent part of existing (already installed) windows.
