Production of double-glazed windows

LOSK manufactured the first double-glazed window in 1992.

The product was unique and difficult to understand. Many people asked, 'why?'

The company developed a direction for the production of double-glazed windows in parallel with the construction of the factory for the production of plastic windows in Pisochyn, Kharkiv region. In 1998, the first double-glazed window was made on a semi-automatic line purchased from the Italian company 'Forel', which met all requirements and norms. This was the first production line for double-glazed windows in Ukraine.

The Austrian company Peter Lisec's semiautomatic double-glazing production line has eliminated the human factor from labor-intensive and responsible assembly processes, reducing the number of employees and increasing productivity.

Various types of special glass can be used in glass production to create multifunctional glass. This glass can be sun-protective and energy-saving, as well as impact-resistant, puncture-proof, bulletproof and safe. The technologies available today make this possible.

The double glazing production line comprises the following modules:

1. Automated primary sealing of glazing BASE BUTYLE.
2. The thickness of the glass is from 3 to 25 mm.
3. The maximum sizes are 2500x2500 mm.

Laminated glass (triplex)

Glass lamination occurs in a special chamber called an autoclave. The layers of glass are glued together under pressure and high temperature. This process is time-consuming but the company uses it because it produces the highest quality lamination.

Losk has been producing laminated glass for over five years. During this time, the company has tested various manufacturing methods and has settled on what we believe to be the most reliable method: gluing the glass in an autoclave under pressure at a temperature of 150°C.

We only use polyvinyl butyral film as our adhesive material. This is because no liquid polymer can currently compete with the film, resulting in better optical and strength properties for the triplex produced with it.

Depending on the destination, we can produce the following types of laminated glass:

• Resistant to mechanical stress
• Bulletproof
• Explosiveproof
• Fireproof
• Noise protective
• Frost resistant
• Multilayer with special properties (such as radio interference, biological or information protection)

Sandblasting (matting) of glass

The LOSK company in Kharkov uses modern equipment to sandblast (frost) glass and mirrors.

The machine is equipped with a movable frosting chamber, unlike the traditional method of moving glass on a conveyor. The glass is kept immobile during the process. This allows for work with workpieces of complex shapes and eliminates the appearance of scratches on the back of the glass.

The borders of the matting area and the speed of movement of the camera and carriage are set using the CNC system.

Technical data:

• The maximum glass size is 3000 x 2250 mm.
• Productivity 5..9 min / m2
