sapsan S6 is a promising series designed specifically to optimize costs for budget-oriented projects. Its primary advantage is thermal performance comparable to the WD64 series, achieved through the use of a 24 mm thermal break. While its low metal consumption imposes stricter limits on the size and weight of structures, smart project optimization can bring the cost down to a level competitive with PVC products. The S6 series supports triple-pane glazing units up to 36 mm and is most in demand in southern regions.
