OS2 Door and Window Systems

NEO | METAL

Brand: Secco

The OS2 series consists of window and door systems that translate SECCO’s minimal steel profile philosophy into different performance levels. Profile depths ranging from 40 mm to 85 mm offer scalable solutions—from interior partitions to large openings requiring high thermal performance. Glass thicknesses vary from 21 mm to 58 mm, with thermal and acoustic performance increasing in line with profile depth. The series includes inward- and outward-opening, tilt & turn, lift-and-slide, and folding systems, as well as horizontally and vertically operating pivot solutions. Finishes in galvanized steel, stainless steel, brass, and corten ensure full material consistency across all accessories.
