What does "OC" mean in the name Ecofutural OC?

OC stands for "Concealed Sash" — the frame fully conceals the sash profile from the outside, creating a modern, minimalist appearance without visible sash lines.

Why is the Uw of Ecofutural OC higher than the standard one?

The Uw value of 1.4 W/m²K for Ecofutural OC applies to single-chamber glazing (not 2-chamber as for the others). With 2-chamber glazing the parameters will be better.
