Rounded edges of frame and sash create a harmonic ambience with the white UPVC window, but also with the aluminium attachment clad. I-tec insulation, Internorm's new insulating technology, insulates the frame continuously and improves the thermal insulation considerably. The all around gluing of the glazing bead additionally ensures stability and security for the window. I-tec ventilation ensures sufficient fresh air and perfect room climate 24 hours a day and can be integrated upon request.
