Security and Energy Efficiency 

OS2’s advanced technology ensures high performance with minimal profiles, allowing for large window sizes and excellent insulation. The thermal break profiles are made of two metal shells joined by extruded polyamide, ensuring high insulation and energy efficiency with U-values as low as 1.1 W/m²K, significantly reducing energy consumption. The system also offers high security with anti-burglary features up to RC3, providing peace of mind alongside aesthetic appeal.
