Frequently Asked Questions (FAQs)

1. What is vacuum insulated thermos?

Vacuum insulation means that your thermos features an insulating layer between the two inner stainless steel or glass sections. Together, these design elements keep your coffee cold or hot.

2. What is a vacuum insulated container?

Vacuum insulation is a specific type of insulation that uses a man-made vacuum between two panels of materials, such as glass or stainless steel, so that the temperature of the fluids or gases on either side of the panels are isolated and don't affect each other.

3. Do thermoses have a vacuum?

The scientific secret to a thermos is a vacuum. No, not the kind of vacuum you use to clean your floors. We're talking about the kind of vacuum that simply means the absence of air. A thermos is a bottle with a double-walled container inside of it.

4. How do vacuum insulated containers work?

Vacuum bottles are effective because they reduce heat transfer caused by conduction, convection, and radiation. The vacuum between the two walls of the glass or metal vessel greatly reduces heat transfer due to convection and conduction.
