Windows manufactured in Poland

GEALAN profile windows are not only aesthetically pleasing, the sophisticated and elaborate profile geometries meet the highest requirements in terms of thermal and acoustic insulation, burglary protection and ventilation. Windows made from GEALAN profiles represent the state of the art.

The flexible centre seal contributes significantly to the thermal insulation of the window. In addition, it protects the hardware components from moisture and thus ensures a more efficient operation of the hardware when opening the window, especially at low temperatures outside.
