The advantage of ECONOMY windows is especially their dimensional stability. Thanks to the high quality galvanized reinforcement, the windows will last for a longer time, and retain their insulating properties. The surface of the windows is extremely smooth and resistant to damage.
As a standard, the ECONOMY windows come with high quality double glazing with plastic distance frame. Thermal insulation values, however, are significantly improved by choosing triple insulation. Perimeter fittings Siegenia FAVORIT are fully adjustable in three directions, with optional microventilation feature.
Most popular color of these windows is white, but on request, this product line is also available in one of four basic wood decors.
