Does double wall glass have the function of heat insulation?

Double wall glass is becoming more and more popular these days. For the first time I saw it, I wonder what is it inside the double wall. It is vacuum? And, if you watch carefully, you can see a pore at its bottom.

As a matter of fact, it is not vacuum inside the double wall but air. If there is vacuum in it, when we break the cup accidently, we will hear a huge sound. What’s more, it will blow out glass fragments. So it is very dangerious if there is vacuum inside it. As for the pore, in order to avoid deformation and breakage in the process of blown production, there is a pore at its bottom. After the production finish, people will cover the pore.

Here comes the question: does double wall glass have the function of heat insulation?

Of course the answer is yes. Double glass has the function of heat insulation to some extent. The interlayer slow down the process of heat loss so as to keep warm.
