All published performance data is reported in imperial units and reflects Centre of Glass (C.O.G.) values generated through Vision v4.0 simulation modeling. U-values and R-values are calculated in accordance with ASHRAE winter design conditions.
Please note that overall window performance is influenced by additional factors including frame construction, cladding, profile design, spacer systems, and installation conditions. Complete unit thermal values may vary depending on the selected configuration.
