Some people may think as a high-end, innovative energy efficient glass, it must have a very complex manufacturing process behind it, corresponding to the status of high-end products in people's minds. Is it really that difficult to make vacuum insulated glass? Let us briefly outline the birth of vacuum insulated glass below.

First, wash two pieces of glass panes ( the glass panes can be float glass, wired glass, tempered glass, rolled glass, sandblasted glass, heat absorbing glass, ultraviolet absorbing glass or heat reflective glass, etc.);

Next, place cylindrical supports measuring 0.1 to 0.5 mm in height and 0.3 to 1.0 mm in diameter or linear or lattice-like supports measuring 0.4 to 0.6 mm in width on one of the glass panes at 10 to 25 mm spacing;

Put the other glass pane on top;

Apply solder glass ( It can also be low melting point metal, flexible metal, or organic binder) around the edges of the glass panes ;

Heat at 450 ° C for 15 to 60 minutes to remove moisture and organic matter attached to the glass;

Seal two glass panes edges with solder glass to form a whole piece;

Open a venting hole at an appropriate position for vacuum extraction by using a vacuum pump, ensuring the vacuum pressure between the two glass panes reaching 0.001 mm Hg to make vacuum insulated glass.

The six steps seem simple. In reality, the complete vacuum insulated glass production process involves nearly one hundred production procedures. It requires high precision and demanding requirement for the production environment. Not integrating intelligent automation technology into the process will lead to low production efficiency, directly impacting vacuum insulated glass performance and stability. The product will lose its commercial application value as a result.

LandVac® by LandGlass uses high quality fully tempered glass pane as substrate. At LandGlass,an intelligent production line is employed to manufacture vacuum insulated glass. It can effectively shorten the manufacturing cycle time of vacuum insulated glass, making sure every step in the processing is precise and controllable. Production yield and efficiency are increased. LandVac® also uses lead-free flexible metal solder for edge sealing, which has been certified by Rohs Europe to ensure it is safe and lead-free. Following the implementation of national energy conservation regulations and green building policies, vacuum insulated glass has become the preferred energy-efficient window & door product for green buildings, including passive houses, energy efficient buildings and zero energy consumption buildings.
