The applications of vacuum insulated glass found in the field of transportation mainly involve windows and roofs of vehicles such as trains, automobiles, high-speed trains, and ships. Because of its outstanding performance in thermal insulation, sound insulation, and condensation resistance, the use of vacuum insulated glass improves the comfort level of the driver and passenger compartment in terms of temperature, hearing, and visual experiences. In addition, it can also decrease the material consumption for window frames and window thickness, eliminate the window condensation phenomenon, and greatly lower the energy usage by air conditioning.
The product performance parameters vary depending on its specific configurations, as shown in the following table:
