The window KV 350 with integrated blinds is a very narrow window despite its profiled edges of window sash and window frame. It features four main advantages: As well as the best sound reduction and thermal insulation, sun and privacy protection are also integrated directly in the window. This helps with cleaning - the blind is protected by glass panes from wind, bad weather and dirt. Sun protection is now also available in refurbishments or on facades, even if they do not permit roller shutters. I-tec shading works fully self-suffciently and offers many other useful functions.
