Abstract
A multilayer insulating glass having at least two panes of glass and a resistance heating element on a glass surface. The panes are separated by a spacer comprising two parallel hollow sections and an insulating web of unfoamed and cured polyurethane casting compound filling the interspace between the hollow sections. The web forms a hard and permanent bond with the hollow sections, creating a spacer having relatively high torsional rigidity and electrical insulation and having relatively low thermal conductivity.
