Superior insulation the copper plating on the inner wall is an extra line of defense against temperature transfer. Heat escapes much slower so your hot coffee stays hot even in a snow storm, and heat enters much slower so your ice water doesn't melt even under a blistering summer sun. On average, copper vacuum insulation can make a difference of up to 9℉ (5℃) over the course of 24 hours.
