Cosabella SD-23
From residential developments and commercial spaces to wide balconies and outdoor transitions, it adapts flexibly to different project types requiring both durability and aesthetics. Its 37 mm visible central interlock creates a more substantial, balanced profile and provides high structural strength. Running quietly and smoothly on stainless steel tracks with special rollers, SD23 offers a load capacity of up to 140 kg. Double glazing up to 28 mm and a special 90 mm sash height combine robust glazing configurations with practical sliding operation. Class 6A watertightness, Class 3 air permeability and C1/B2 wind load resistance, certified to international standards, demonstrate SD23’s balanced and reliable performance.
