Warm windowsill

The window sill profile is used to seal the bottom joint of the window, ensuring perfect tightness against water and blow-by (limiting the value of linear thermal bridges) preventing the effect of the so-called “waving curtains”. Thanks to the adjustable contact surfaces, it is also the basis for the external and internal window sill. Made of high density XPS extruded polystyrene.
