Which will conduct more heat single-pane window or a double-pane window?

A single-pane window will conduct more heat than a double-pane window. This is because a double-pane window has two layers of glass with a layer of insulating gas or air between them, which reduces heat transfer. The added insulation in double-pane Windows helps to keep indoor temperatures stable, making them more energy-efficient. Consequently, double-pane Windows are preferred for better thermal performance.
