Figures from the BO Fenster 2026 brochure (pp. 3–15). Uw refers to the window, Ug to the glazing. Thermal values are calculated for a reference window; actual performance depends on dimensions, glazing and options. Sound insulation depends on the selected glazing. Values marked “To be confirmed” require validation of the glazing configuration. Final specifications are provided in your quotation.
