KF 410

Complete flush transition from sash to frame unites the KF 410 to one unit. If the frame is rendered on three sides into the brickwork outside, only the narrow, square-edged frame of the sash remains visible. The new I-tec insulation technology facilitates continuous insulation in the frame, thus improving thermal insulation considerably. Technological advantage concerning airing is provided by the I-tec ventilation. The ventilation system, integrated into the frame, ensures sufficient fresh air and perfect room climate for 24 hours a day.
