Advanced Renovation Features

Seamless Integration: Equipped with renovation fins (35 mm or 65 mm) that neatly cover old frames and provide a clean, aesthetic finish.

Peak Thermal Performance: With a 6-chamber frame, it achieves an industry-leading 0.83 Uw for Ug = 0.5, making it the ultimate choice for thermal modernization.

Closed Section Steel: Superior structural stability allows for large glass spans without the need for extra bars or mullions.

Triple Gasket System: Three levels of sealing ensure maximum acoustic insulation and wind resistance.

Premium Glazing: Supports advanced glass packages up to 54 mm (STV technology) or 52 mm (standard).

Innovation & Surface Design

Every S9000 window is a masterpiece of technology. We utilize V-Perfect technology for virtually invisible welds and STV® dry glazing for enhanced structural bonding. For a vibrant, weather-resistant finish, choose acrylcolor technology, which offers a surface twice as hard as standard PVC.
