Condensation is only able to form on surfaces that are cooler than the surrounding air. There must also be a high content of water vapour in the air. However, because double and triple glazing is better at reducing heat loss from a room than single glazing, the inner pane of a double or triple glazed window will have a higher surface temperature than a single pane window. As a result of the warmer glass surface, warm, moist air that is present in the room is less likely to turn into condensation when it meets the surface of the window.
