The Innovativ-ST 60 is our most versatile solution for a really unique all-steel window system.  It has a fairly narrow depth that can still handle a wide enough triple-pane glazing unit to make some applications near passive house grade. This is due to the high strength of steel in which just a single thin wall can provide enough structural integrity to hold a heavy glazing unit.  The profile system comes in three styles (Basic, Warm, and Slim) which only have a modern square exterior shape and can handle up to a 44mm-wide glazing unit. All three models have an option to be in full stainless steel for a truly luxurious upgrade.  The thermal break connectors provide a surprisingly decent amount of thermal performance for an all-steel profile, especially in the Warm model, where it is wider. The Innovativ-ST 60 window system is for those who need or want a really narrow profile in any material:  47.5mm in Fixed configuration for the Basic and Warm models; only 25mm (~1 inch) in Fixed configuration for the Slim model!!!  This makes the Slim model the perfect solution to replace windows in old industrial buildings and warehouses where the look of the original slim steel windows may need to be replicated for historical preservation requirements.  If the slimness of the profiles are not a priority, the Basic and Warm models also come in a slightly more insulative taller option of 72.5mm (Fixed conf.), while the Slim model comes in a taller option of 40mm (Fixed conf.).
