What it is
Aluminium windows
The Ecofutural variant with a concealed sash.
Role in the project
Ecofutural OC
OC is a separate variant of the Ecofutural family, with its own profile section and geometry.
What to consider
Purpose and limitations
Ecofutural OC, Genesis SU, Superial SU and Max Light INVISIBLE each have their own construction and technical data.
Versions in the Ecofutural family
One flexible base, two facade geometries
Ecofutural is a thermally broken window and door family with a 65 mm system depth. It comes in a standard version with a visible sash and a separate OC version with a concealed sash. OC changes the geometry and how the window looks from outside; it is not a higher level of thermal insulation than the basic system.

Technical system name
Standard visible-sash versionEcofutural
The flexible Ecofutural base for common opening types, with a wide range of infills and a choice between the standard thermally broken version and the ‘i’ and ‘i+’ variants, depending on the calculations for each unit.

Concealed sashEcofutural OC
OC is chosen when a cleaner exterior line and a less visible sash are the priority. It has its own sash and infill geometry; it is not a cosmetic add-on to the standard Ecofutural window.
