Generally, hollow glass is still selected. The reasons are as follows:
Vacuum glass is a new type of product. It uses properly dispersed particle pillars as the distance, the void layer is only 0.1~0.2mm, the vacuum in the cavity is free of gas, and the vacuum degree reaches above 0.1 Pa. As a new generation of energy-saving glass, it has better heat insulation and insulation, and its insulation is about 4 times that of single piece of General glass; Due to the high thermal resistance of vacuum glass, it has better functions of preventing condensation and frosting, therefore, it is extremely beneficial to winter lighting in dry and cold areas. However, due to the high manufacturing process requirements and high cost of vacuum glass, if it is used on broken bridge aluminum doors and windows, the price of vacuum glass may be higher than that of broken bridge aluminum itself, in addition, the gap of vacuum glass is only 0.1~0.2mm, and the base cannot be installed on the broken bridge aluminum. It can be applied to curtain wall or ordinary aluminum alloy doors and windows. The minimum gap of broken bridge aluminum doors and windows glass is 6mm, therefore, it is not practical to use vacuum glass on broken bridge aluminum doors and windows, so the glass on broken bridge aluminum doors and windows market is made of hollow glass.
The wind pressure resistance of vacuum glass is about twice that of hollow glass made of the same glass, but the impact strength is not as good as that of hollow glass. At the same time, because the production process of vacuum glass is more complicated than that of regular glass and the raw materials are more expensive, the price of vacuum glass is relatively expensive.
In general, home decoration replacement broken bridge aluminum doors and windows you can choose to use vacuum glass according to the decoration requirements. If you pursue the quality of life and have higher requirements on heat preservation and sound insulation, you can choose it, but it is not just needed.
