The Internorm KF 220 window is available as uPVC only or uPVC with an aluminium cladding. The narrow, square-edged window frame gives the impression of fixed glazing but the window can be opened. The frame can be rendered on three sides for a frameless appearance. The glass pane is bonded giving all round excellent stability, thermal insulation and security.
