Document Type and Number:
WIPO Patent Application WO2007039747
Kind Code:
B1
Abstract:
A laminated glazing comprising two panes of glazing material, a sheet of interlayer material extending therebetween, and an electrically conductive member formed (possibly etched) from a sheet of electrically conductive material also positioned between the panes. The electrically conductive member may be a heating element which comprises a plurality of spaced apart, fine heating lines, electrically connected to a pair of busbars. The heating element may be divided into at least two heating zones, each having a different power density, and/or it may include a non-heated area. Also a method of manufacturing such a glazing involving locating a pre-formed electrically conductive member and . a sheet of interlayer material on a first pane of glazing material, placing a second pane of glazing material in register with the first so that the electrically conductive member and the interlayer material are between the two panes, and laminating in an autoclave.
