Insulating Glass Production Process
Insulating glass is typically composed of two or more glass panes separated by a spacer filled with air or gas, such as argon or krypton. The space between the glass panes reduces heat transfer, resulting in better insulation and energy efficiency. The production process typically involves the following steps:
- Glass cutting and Low-E edge deletion
- Washing and cleaning of the cut glass
- Spacer preparation and primary sealing
- Gas filling
- Assembly of insulated glass units
- Secondary sealing
Each of these steps can affect the overall cost of producing insulating glass, so optimizing each step is essential to minimize costs. Below we will explain them in details.
- Glass Cutting and Low-E Edge Deletion
Glass cutting and low-E edge deletion are critical steps in the production of high-quality insulating glass units. Glass cutting involves cutting the glass to the required size and shape using specialized cutting equipment. It is important to ensure that the glass is cut accurately and with minimal wastage to minimize production costs.
Low-E edge deletion is the process of removing the low-E coating from the edges of the glass to prevent the coating from interfering with the sealant bonding. This process is typically done using specialized equipment that removes a small portion of the low-E coating from the edges of the glass.
- Washing and Cleaning of the Cut Glass
After the glass cutting and low-E edge deletion process, the glass is thoroughly washed and cleaned to remove any contaminants that may affect the performance of the insulated glass unit. This step is critical as any dirt or residue left on the glass surface can interfere with the bonding of the sealant and spacer.
The glass is typically cleaned using automated washing equipment that sprays the glass with water and a cleaning solution. The glass is then dried using specialized drying equipment that ensures the glass is free of any moisture.
- Spacer Preparation and Primary Sealing
Insulating glass spacers is an essential component of the insulated glass unit, providing structural support and maintaining the distance between the glass panes. The spacer is typically made of aluminum, stainless steel, or warm-edge materials, such as thermoplastic spacers.
Spacer preparation involves cutting the spacer to the required size and shape and applying a butyl sealant to the spacer surface that will bond with the glass panes. The sealant used in this process is butyl sealant.
- Gas Filling
Gas filling is the process of filling the space between the glass panes with a low-conductivity gas, such as argon or krypton. This gas helps to improve the insulation properties of the insulated glass unit, reducing heat loss and improving energy efficiency.
The gas filling process typically involves inserting the spacer into the glass panes and sealing the perimeter with a secondary sealant. The gas is then injected into the space between the panes using specialized equipment.
- Assembly of Insulated Glass Units
After the gas filling process, the glass panes are assembled into the insulated glass unit. This typically involves placing the glass panes onto a specialized assembly line and bonding the spacer to the glass panes using the sealant.
The assembled insulated glass unit is then placed into a press that applies pressure to ensure that the sealant bonds properly to the glass and spacer. The unit is left to cure for a specific period, typically between 24 and 48 hours, to allow the sealant to set and cure fully.
- Secondary Sealing
After the curing process, the insulated glass unit is removed from the press, and a secondary sealant is applied to the perimeter of the unit. The secondary sealant helps to improve the structural integrity of the unit and prevent any moisture or gas leakage.
The secondary sealant used in this process is typically a two-part silicone sealant, polyurethane sealant or hotmelt sealant that is applied using a glass sealing extruder or with an automatic glass sealing robots which can be integrated to insulating glass production line. The unit is then left to cure for a further period to allow the sealant to fully set and cure.
In conclusion, insulating glass production is a complex process that involves several critical steps, including glass cutting, low-E edge deletion, washing and cleaning, spacer preparation, gas filling, assembly of insulated glass units, and secondary sealing. Each of these steps is essential to produce high-quality insulating glass units that provide excellent insulation properties and energy efficiency. Manufacturers must optimize each step of the production process to minimize costs and ensure consistent quality in their products.
