Check the thermal envelope first
Before selecting a profile, establish whether the window separates a heated room from outdoors. For a thermal envelope, select a thermally broken system and calculate the complete window.

The manufacturer describes ConceptSystem 59Pa as a non-insulated system developed for warm climates. It is not an insulated external window solution for a heated home in Kharkiv: the intended application requires a separate check. Geometry and classes in the table follow the Ukrainian and global Functional sheets. Those technical sheets do not state Uf or Uw; we do not substitute the glazing Ug value. RC2 and weather performance depend on the tested configuration.
Performance depends on dimensions, profile combinations, hardware and glazing. Each opening requires its own specification; catalogue maxima are not a guarantee for every element.
The Ukrainian and global Functional sheets agree on the listed figures. Neither sheet specifies Uf or Uw for this non-insulated system.
Variant availability, hardware and delivery terms in Ukraine must be confirmed for the project. A catalogue listing does not imply stock availability.
DESIGN CHECKS
Before selecting a profile, establish whether the window separates a heated room from outdoors. For a thermal envelope, select a thermally broken system and calculate the complete window.
The 4–35 mm range describes the permitted vent infill thickness. An efficient insulating glass unit does not by itself turn a non-insulated profile into a thermally broken frame.
E750, C5 and RC2 are not universal guarantees for any size or hardware. Coordinate the layout, junctions, glazing and actual specification together.
