The laminated glass looks normal but is special because it is made through a lamination process. Laminated Glass Interlayer Films offer higher durability, weather resistance, sound dampening, and several other features.
Below is the complete step-by-step process of making laminated glass.
The glass comes in bigger sheets, and so do the interlayer films. However, not every application requires the biggest sheet of glass. That's why the first step involves cutting glass into the required size. It is also the phase where the glass design can be customized according to the customer's requirements.
Cutting and making laminated glass starts with the raw and dirty glass. Small particles can increase the distance between layers of glass with multiple gaps. So, after cutting is complete, phase two includes using feeding devices to convey glass into the washing machines using roller tables.
All the gaps and impurities on the surface of glass panels are minimized as the glass moves through this phase. However, it is just the initial cleaning phase of this process.
The cleaning of glass panes continues as we go through the drying phase of the process. Automated machines are used to dry the glass panes when the glass is completely cleaned. The specialty of this process is that the glass stays clean since the drying process is conducted in a controlled environment.
However, it is still insufficient since the glass is not ready for lamination. So, it still needs to be stored in a controlled environment.
As the storage process starts, cleaned and dried glass panes are transferred inside a clean room. This room is not only clean from any contaminants, but it also has controlled humidity and temperature. It is dust free and not only the glass but also the PVB interlayer film rolls are present here since there are the least chances of causing any contamination on the glass.
The sandwich of glass and the interlayer film is firstly aligned with the highest accuracy, and then they are pressed through the nip roller. This roller heated, heats, and compresses the multiple layers together. This process binds all layers while removing air to create a perfect laminated glass.
The last process involves transferring glass to an auto-clave card. It is the final stage of making laminated glass, and here controlled cycles of pressure and heat and applied to the sandwich. These controlled cycles make the sandwich look like one clear layer of glass. After this process step, the laminated glass is ready for installation.
Laminated Glass Interlayer Films can play a huge role in architectural design since the glass differs from base glass. However, with different types and options available, it is essential to know which one works best for your use case.
