Description of Preferred Embodiments The present invention utilizes known materials (glass, bounding materials, lower strength materials having good thermal insulation properties e.g. plastics like PVC, high strength materials e.g. high strength steel and high strength corrosion resistant steel) and known assembly methods. Novelty of the present invention comprises: joining the perimeter bars 33A, 33B, 33C, (Fig 1, Fig 2, Fig 3) made of high strength material, to the inner bars 31 made of high strength material, with high strength joints, thereby creating the grate 13; placing the grate 13 between the two panes 35; using the perimeter bars 33Λ, 33B, 33C of the grate 13, as spacers for the two panes 35; creating the high security insulated multi-pane window and door system in which the interlocking elements 40, 41 of the grate 13 interlock with the channels 43, 69 e beded in the outer frame 14; creating the high security insulated multi-pane window and door system in which the removable sashes 15, can not be removed in locked position of the lock 61, neither when . the lock bolt 49 is in an opening 45 (non venting position), nor when the lock bolt 49 is in openings 46, 47 (venting positions); creating the high security insulated multi-pane window and door system of which the high strength elements: the grate 13, the channels 43, 69 and the lock 61, can not be disassembled in the locked position of the lock 61, that means when the lock bolt 49 is in the openings 45, 46, 47; creating the high security insulated multi-pane system- assembly, which appears to be ordinary dual-pane glass window or door with colonial grids, but has burglar and alike resistan as a high strength steel grate. Referring to Fig 1, Fig 2 and Fig 3 (which are side view and two cross-sectional views of the same system) there is shown high security multi-pane sliding window and door system 10 as seen from interior of a building. The difference between the window system 10 and the door system 10 depends only on size of sashes, frames, trolleys and location of the system in a wall. The basic element of the high security multi-pane sliding window and door system 10 is the grate 13, made of high strength material. The grate 13 comprises of the perimeter bars 33A, 33B, 33C (which act also as the pane spacers for the panes 35), the inner bars 31, the top interlocking elements 41, the bottom interlocking elements 40, the lock cover 44, and bolts 50, 51, 66. The perimeter bars comprise of side perimeter bars 33Λ, top perimeter bars 33B, and bottom perimete bars 33C. All the perimeter bars 33Λ, 33B, 33C have mitered (at angle 45 degrees) ends. The top perimeter bar 33B is prewelded to the side perimeter bars 33A, the inner bars 31, and the top interlocking elements 41. The lock cover 44 is prewelded to the side perimeter bar 33Λ. The bottom perimeter bar 33C is prewelded to the bolts 50 in such arrangem as to be locked into cutouts 50A of the inner bars 31. The inner bars 31 (after preweldeing all elements: 31 and 33Λ to 33B, 44 to 33A, 50 to 33C) should be inserted therein hollow core plastic bars 39. The plastic bars 39 are integral part of a premoulded plastic grid 16. The premould plastic grid 16 consists of the hollow core plastic bars 39, welded to them hollow plastic bars 59, continuous plastic bars 34 prewelded to the bars 39 and 59. The continuous perimeter plastic bar 34 has mitered (at an angle 45 degrees) outside corners 53Λ to allow for better penetration of the bounding material 53. After inserting the plastic grid 16 onto the inner bars 31 (which form prewelded upper part of the grate 13, consisting of the bars 31, 33Λ, 33B, the lock cover 44,and the top interlocking elements 41), the lock 61 should be inserted into the lock cover. Then the lower interlocking elements 40 (containing the trolleys 57) should be bolted to the bottom perimeter bar 33C (using bolts 51), and the bottom perimeter bar 33C should be bolted to the side perimeter bars 33A (using bolts 66). After the inner bars 31 are inserted into the plastic grid 16 and the grate 13 is assembled, the bounding material 36, 53 can be applied on surfaces of the perimeter bars 33Λ, 33B, 33C. Then the sealed double pane unit 17, having the plastic grid 16 and the grate 13 inbetween the panes 35 can be assemble The sealed double pane unit 17 is inserted into the side, top, and bottom sash frame 37 elements, which are welded together at their corners, forming in result the complete sash 15. Before welding of the sash frame 37 elements, gasket 38 is inserted between the sealed double pane unit 17 and the sash frame 37. Basically the side, top and bottom elements of the sash frame 37 have the same design, dimensions and cross-sections. The differences being: different weather stripping locations in the top, bottom and side elements of the sash frame 37; cutouts for the bottom interlocking elements 40 in the bottom elements of the sash frame 37; cutouts for sash cover elements 60 in the side and top elements of the sash frame 37 (the sash cover elements 60 secured with bolts 63, are installed to improve thermal insulation of the system 10); longitudinal cutout in the top component of the sash frame 37 to allow installation and removal of the sash 15; cutout (in the side and bottom elements of the sash frame 37) to accommodate the lock cover 44. The outer frame 14 (made of lower strength material having good thermal insulation properties e.g. plastic like PVC) of the system 10, having inserted the bottom channels 43 and the top channels 69 (made of high strength rigid material) in the top outer frame elements 67 and the bottom outer frame elements 68. Inserting high strength material elements into side elements of the outer frame 14 is optional depending on conditions, they can be bolted to the bottom channels 43, the top channels 69 and are especially needed, when several of the system 10 doors and, or windows are grouped in a row side by side. The top outer frame elements 67 and the top channels 69 have cutouts 55A to accommodate bolts 55 fastening the outer frame 14 to a building or other structure and the cutouts 48 to allow removal of the sash 15. There There are three or more outer frame cover elements 56 (installe to improve thermal insulation of the system 10). The outer frame cover elements are fastened to the top outer frame element 67 with bolts 64. The bottom outer frame element 68 and the bottom channel 43 have cutouts 54A to accommodate bolts 54 fastening the outer frame 14 to a building or other structure, and the openings 45, 46, 47 to accommodate the lock bolt 49. Location of the openings 46 and 47, should be such, that not to allow for ventilation gap larger than 4 inches (101.6 millimeters). Location of the cutouts 54Λ, 55A, the bolts 54, 55 should be such, that not to allow for disassembling of the system 10, while the lock bolt 49 is in one of the openings 45, 46, 47. At least two bolts 54 should be covered by the lower interlocking elements 40 of each sash 15 and at least two bolts 55 should be covered by each sash 15 everytime, while the lock bolt 49 is in one of the openings 45, 46, 47. Length of the bolts 54 and 55 should be more than 4 inches (101.6 millimeters) . Location of the cutouts 48 should be such, that not to allow for the sash 15 removal, while the lock bolt 49 is in locked position in any of the openings 45, 46, 47. In order to remove the sash 15 from the outer frame 14, the bolts 63, 64, the outer frame cover elements 56 and the sash cover elements 60 must be removed. Then the cutouts 48 and the bolts 41 should be lined up. The sash 15 (the one closer to a building interior) should be lifted up, so the bolts 41 penetrate into the cutouts 48. Next the sash 15 (while lifted) should be rotated (along a contact line of the bolts 41 and the cutouts 48) and moved towards interior of the house (or other structure) to complete removal of the sash 15. The same procedure should be carried out to remove the remaining sashes 15. The reverse procedure should be carried out to install the sashes 15. The outer frame 14 has provision for screen panels 58. For better thermal insulation and cutting on noise (while operating the system 10) the top interlocking elements 41 and the top channels 69 should be covered with plastic.
