Advantages of Using Double-walled Glass over Regular Glass


There are many different types and shapes of double wall glass, such as double wall glass, mugs, jugs, bottles, goblets, pots, pans, colored items ......


1、What is the function of double wall glass?

Double-walled glass cups use the principle of double-layer structure, which enhances the comfort of the cup and also improves the insulation function of the glass. In addition to the humanized design, double-walled glass has a good aesthetic value. The transparent material combined with the two-layer structure almost sublimates drinking tea into a dynamic artistic act.


Many glass manufacturers produce double-layer ice buckets. Vacuum double-layer glasses are usually hand-blown. The double-layered glass provides thermal insulation and can also store ice cubes. During the blowing process, if the middle layer is not a vacuum, the outer layer of the glass has a venting hole. This is to vent the gas from the glass to prevent the glass from deforming and exploding. After the production is finished, the hole is sealed. So there is gas in the middle of the two layers.

They are made of high borosilicate glass, and the applicable temperature is -20°C~150°C. If you want to buy a glass for yourself, it is recommended to buy a double-layer glass. If there is boiling water inside the cup, double-layer glass will not be hot, if there is water. But a single-layer glass is too hot and easy to burn.


The double glass design greatly reduces the thermal conductivity of the cup, which can effectively play the role of heat insulation and scale prevention when used. Insulated glasses keep cold drinks cold and hot drinks warm while the outer surface always feels comfortable in your hands.
