Is single-layer glass better or double-layer glass better?

Compared with other materials, the glass water cup can be regarded as a safer water cup. In addition to the clear and transparent material, the reason why the glass cup is popular is its safety performance. There are some differences between single-layer glass and double-layer glass.

Double-layer cups have the functions of heat insulation and heat preservation that single-layer cups do not have, especially for glass water cups. The thermal conductivity of the glass is very strong. When boiling water is poured in, the whole body of the glass will be very hot after a short while, and the appearance of the double-layer glass can effectively eliminate this problem.

Because of the double layer, the temperature of the boiling water is difficult to spread, which can increase heat preservation and also has a good heat insulation function. In terms of various properties, the benefits of double-layer glasses are obvious, and they are better than single-layer glasses. Even so, there is one thing that a double-layer glass is not as good as a single-layer glass, and that is the weight. Except for this shortcoming, a double-layer glass is better than a single-layer glass
