Profiglass, a Serbian glass-processing company based in Belgrade, specialises in the production of insulating glass units (IGUs) for window manufacturers and construction applications. The company combines flat glass processing with precision IGU assembly, focusing on glazing solutions designed to improve thermal insulation, acoustic comfort and overall building performance.
At the centre of Profiglass’s production is the manufacture of double and triple insulating glass units, configured according to the thermal and technical requirements of individual projects. IGUs can incorporate different glass compositions, including clear, Low-E and solar-control glass, allowing the glazing configuration to be adapted to requirements for U-value, solar heat gain, daylight transmission and energy efficiency.
Spacer technology is another important component of the company’s IGU production. Precisely formed spacers maintain the required distance between glass panes and create the insulating cavity, while appropriate primary and secondary sealants contribute to the unit’s gas tightness, moisture resistance and long-term durability. Depending on the specification, insulating cavities can be configured for air or inert-gas filling, supporting improved thermal performance.
Profiglass also focuses on dimensional accuracy and repeatability throughout the manufacturing process. Precise glass cutting, edge processing, spacer preparation, unit assembly and sealing are essential for maintaining consistent IGU geometry and ensuring reliable integration into modern window and façade systems. 
The company’s insulating glass solutions can be configured for a wide range of applications, from residential windows and doors to commercial façades, office buildings and large glazed surfaces. Different glass thicknesses, pane combinations and functional coatings can be selected to meet project-specific requirements for thermal insulation, solar control, safety and sound reduction.
For contemporary façades, where glazing represents a significant portion of the building envelope, correctly engineered IGUs play a critical role in balancing energy efficiency, daylight, occupant comfort and architectural transparency.
