ECOFUTURAL OC
Presentation
ECOFUTURAL OC
A three-chamber window and door system designed for high thermal insulation with a fully concealed sash — the glazing profile remains invisible from the interior. The specially designed frame shape hides the full profile height of the sash, creating a clean glass-dominant aesthetic. Supports Monoblok-type window design with a narrow 77 mm sash joint, and is compatible with external roller blind profiles.
