The Live window (wood/glass), has an extraordinary central node of only 59mm, while typically varies from 135 to 164mm and it’s also thinner than of the “most extremes” central nodes in metal alloys. Other plus:
-central symmetry. Normally to reduce the central node and having a symmetry of the profiles is used on both sides a cable tie in overlapping, in Live windows there aren’t overlapping and the windows are incredibly coplanar and symmetrical on both side.
-symmetry between profiles. Always, the dimension of the central node is greater than all other, while in Live window all nodes has the same dimension.
-frame and dk hinges not visible
-perfect alignment between the sash and frame and a small footprint profiles allows greater light penetration to more than 30% compared to traditional windows.
