NEW DOUBLE-HUNG

There is a breast cavity under the window; the two sashes have guiding pins and slide on two parallel vertical grooves located on both sides of the window frame which extends into the breast cavity. Guided by a horizontal connecting section and a crossing section the two sashes can be either in the same groove, or in parallel grooves. For the complete opening of the window, after opening the breast cavity, the two sashes are stored parallel to each other with the aid of a branching section and a horizontal section within the breast cavity. A more detailed description and drawings are to be found in the enclosed patent while the video shows the window in operation. The unique and facile manner in which the window operates makes its use like play. Remote control is an option. We have a working model in Budapest, Hungary... With the current interest in green building, enhanced by government-sponsored consortia, we believe this window would have an important contribution to energy savings..
