What is Insulation Rating (Hours)?
Indicates how long a drinkware item can maintain its temperature for hot or cold beverages.
Definition
The insulation rating specifies the duration, in hours, that the drinkware can keep its contents either hot or cold under specific test conditions. For example, 'Insulation Rating Cold: 28 hours' means a cold beverage will remain cold for up to 28 hours, and 'Insulation Rating Hot: 13 hours' means a hot beverage will stay hot for up to 13 hours. These ratings are typically determined by industry standard tests.
Why It Matters
This rating is a direct measure of performance, telling you exactly how long you can expect your coffee to stay hot or your water to stay cold, which is essential for commuters, outdoor activities, or long workdays.
What to Look For
Higher numbers indicate better performance; 18+ hours for cold and 6+ hours for hot are generally considered premium.
