A wide view of the outside is provided by the +K8000 sliding system, a minimalist line applied to large openings in the Caminho Velho project that blends in perfectly with the project’s distinctive landscape. Noir 100 Sablé is the finish used on the doors and windows of the +K8000 and +E3600 thermal break systems. Along with wood, the selected aluminum systems—which include railings—create a harmonious blend with the Douro.
