What is double wall glass?
Double wall glass is a glass-in-glass quilt. It is made by sucking out the air between two glasses to create a vacuum. Instead of using heating or cooling elements to keep the drink hot or cold, it keeps the drink at the correct temperature by keeping heat from escaping or entering.
This "vacuum" is the best insulator because there is no air to transfer heat. According to a study conducted over six hours, ordinary glasses are terrible at insulating liquids. In contrast, double wall glasses and cups do a good job of keeping drinks at the desired temperature.
Double wall glass is usually made of high-quality borosilicate glass and can usually hold hot and cold beverages. Thanks to the extra wall of glass, double wall glasses keep your drink hotter for longer, so your coffee doesn't get too cold (or too hot) while you continue working or reading the daily news. These double wall glasses are usually very sturdy.
Not only will these double wall glasses keep your drink hot or cold better, but they are also very durable.

The double tumbler is insulated to keep your drink at the right temperature from the first sip to the last.

The double tumbler not only keeps your drinks hot but also chilled drinks. Want to enjoy iced tea or lemonade on your outdoor lounger? Even in the scorching sun, use insulated glass to keep drinks fresh longer. When you're done drinking, place the cup in the dishwasher for an easy clean.
