Bolena Production
Production

Bolena is a manufacturer of PVC and aluminium structures. For the production of PVC (metal-plastic) structures, we use exclusively the PVC profile of the German company REHAU, whose products have enjoyed well-deserved recognition on the European market for more than 50 years. Apart from the components, the equipment on which the products are made has a major impact on their quality. The reliability and durability of your structures depend on it. We use equipment from renowned global brands.

The automated Sturtz line welds all four corners of the structure simultaneously, Federhenn equipment ensures the precise fitting of the hardware, and the insulating glass units are produced on the high-tech Lisec line.

For the production of aluminium structures, we use the Elumatec machining centre.

Clients and partners choose us precisely for the quality of the products we make.

Window Production Line
01
PVC Profile Cutting
PVC profile cutting is performed using Sturtz double head saw. High accuracy of cutting is guaranteed by computer program.
02
Reinforcement installation
The windows are fitted with galvanized steel reinforcement with thickness not less than 1.5 mm.
03
Welding of Elements
Welding, performed with the Sturtz German automated line, ensures maximal durability of welded corners and right dimensions of an element.
04
Seal Installation
Double rubber seal, fitted along the inner perimeter of the window, is wear resistant and remains elastic for 10 years.
GU and Siegenia hardware is installed at the hardware station, which makes the opening and closing process easy and safe.
07
Quality Control
The window is finished after installation of insulating glass. Quality inspector checks the functioning of each window on a special stand.
Bolena uses galvanized steel reinforcement (not less than 1.5 mm), which is placed inside the PVC profile. Reinforcement is inserted into each profile and securely fastened with screws using automatic machines.
Welding of workpieces into one structure is performed using the Sturtz German automated line, which welds all four corners of the product simultaneously, than the welding joints are automatically dressed.
05
Weld Dressing
After weld dressing, welded corners get perfect look.
06
Hardware installation
Hardware is fixed on sashes on Aluma hardware stand. Window functionality and service life depend on proper installation of the window hardware.
All PVC windows and doors are shipped to the customer only after inspection by the quality inspector. Specially trained and certified staff manufactures products that meet standards of the European Union.
Finished Window
Production technologies and components enable to manufacture the window of high quality that meets EU standards.
Production line of energy-efficient insulating glass
01
Glass Cutting
Glass is cut with maximum accuracy using the automated table according to a preset program. After cutting, glass is supplied to Lisec automated line.
02
Primary Sealing
At the station of the primary sealing, butyl sealant is applied on the spacer bar. This sealant secures 90% of water and air tightness of insulating glass.
03
Glass Washing
Glass for insulating glass undergo three-phase washing (wetting, washing and drying) using distilled water.
06
Seconadary Sealing
Thanks to special equipment, solid secondary layer of sealant is applied. This provides long-term service life of insulating glass.
The production of insulating glass is performed using the high-tech line by Lisec, the Austrian manufacturer that is considered to be a European market leader in this field of equipment. Thanks to manufacturing automation, the best tightness of insulated glazing is achieved. This increases the service life and thermal and sound insulation properties of glazing.
04
Insulating glass assembly
Automated equipment for insulating glass assembly secures proper sealing of insulating glass that improves their service life, heat resistance and sound insulation.
05
Filling with Argon
Insulating glass can be filled with argon to improve its heat resistance. The insulating glass unit is filled not less than 95% of argon.
Finished Insulating Glass Unit
50% of insulating glass produced at the factory are made of energy-efficient glass and filled with argon.
