Internorm is continuously developing and evolving its window range to meet the growing demands of its customers. With this, the window and door company has added to its collection of designs with the KF220 – a PVCu /aluminium system.<br> <br> With its glass sash, the KF220 boasts a modern square design that provides a non-visible sash profile. The finished result is one where there is no difference in the outside view between fixed elements and elements that can be opened. With its frameless glass architecture, the window can almost be completely plastered in on three sides, so further enhancing the design's clear line finish.<br> <br> This window design comes with Solar+ glazing as standard. The triple glazing features a special thermal coating that helps maximise the potential energy gains provided through solar irradiation and prevents subsequent heat loss through the window with very low U-values.<br> <br> As with all of Internorm's windows, highlevel security is offered as standard with fully concealed locking parts on the bottom corners.
