Vacuum insulation works by preventing heat transfer from the outside of the bottle to the inside by creating a vacuum in an inner wall. As there is no air in the vacuum, convection cannot occur and the temperature of the liquid remains stable.
Foam insulation works by using foam to prevent convection occurring. It is difficult for air to move in foam so heat can’t transfer from outside the bottle to inside the bottle.
Why Stainless steel?
Stainless steel is corrosion resistant, non-toxic, stable, and non-absorbent and suitable for both hot and cold drinks. Stainless steel provides a stable barrier for vacuum insulation to keep your drinks hot for up to 12 hours.
Keeps liquids hot for up to 12 hours and cold for up to 24 hours. Pre-heat or cool the flask first with boiling or chilled water for best results. For dual hot and cold flasks, undo lid and pour hot liquids into a cup, rather than use the sipper.
