A combination of two or more sheets of glass, separated by a spacer bar and sealed so that it forms a single unit, having one or more air spaces in between is called a Double-Glazed Unit. It is commonly referred to as 'double glazing glass' or 'double pane'. Double glazing or insulated glass evolved from the traditional double-hung windows and storm windows, which separated the interior and exterior spaces using a single pane of glass.
Manufacturing of double-glazing glass mainly includes cutting of the glass, glass edging, washing the glass, spacer assembly, and gas filling.
Glass Cutting
In this step of creating double-glazing glass, a pair of glass panes for making the sealed unit are carefully measured and then cut to size either by hand or by using an automatic cutting table. In addition, a variety of automated solutions, including saws and transfer tables, are used to improve the overall efficiency of the glass cutting process. Such solutions also reduce the mistakes that can cost us a great deal of money otherwise. Swift Glazing has the best-in-breed tools needed to get the job done well.
Glass Edging Once the glass panes are cut and ready, a single unit of glass is formed by sealing the two separate sheets using a sealant. This occurs by freeing the glass from any moisture-sensitive coating, or edge-deleting (removing a strip of coating from around the glass perimeter) to make the sealants adhere to the glass.
This whole process can take a long time. However, you can achieve edge deletion and reduce costly edge deletion failures with a wide variety of cost-effective solutions. You can find a single edge deletion table and a twin edge deletion table at Swift Glazing Equipment. These tables are designed for the safety of the operator as well as for productivity enhancement.
Glass Washer
In the next step, the sealed double-glazing glass unit passes through a glass washer. The washer might be the most critical piece of equipment in the entire process as it makes sure that the glass is entirely free of debris. With Swift Glazing, you can get access to glass washers in 60" and 84" capacity, custom-built to suit the manufacturers' many requirements. A thorough inspection of the units is done after washing to keep up with the quality required.
Spacer Assembly After ensuring that the glass is ready for use, a spacer bar, which is a seal between two panes of a window, is used to combine the single panes of glass. Nowadays, intercept and flexible spacers are being used in place of the historically used metal and fibre spacers. Those spacers were thought to provide durability, but in reality, the metal conducts heat instead of locking in the temperature. Intercept spacers have greater energy efficiency and have the ability to trap or lock the desired temperature. However, their tendency to cause noise and echo through the windows makes them undesirable for some applications.
Flexible spacers are one of the newest materials in the market today. They are far more energy-efficient than other spacers. Also, depending upon the materials used in the manufacturing process of these spacers, they are often considered better insulators than aluminium and intercept spacers.
Flexible spacers (swiggle spacers) have an environment-friendly profile and are quieter than aluminium or intercept seals. Swift Glazing Flexible Spacer Application table assists in setting up a flexible spacer assembly of your double glazing glass.
Gas Filling To further increase an IG unit’s thermal efficiency, gas filling is used. Gas filling equipment for windows work by filling the space between planes with either argon or krypton, which reduces the window’s U-factor rating.Swift Glazing Equipment supplies a range of gas fillers for Argon, Krypton, and Zenon gasses.
