The GEALAN S9000 window system is an elite solution designed for ultra-low energy buildings and Passive House standards. With its 82.5 mm installation depth and advanced triple-gasket technology, it represents the highest level of thermal and acoustic performance available in modern PVC engineering.

Advanced Engineering & Premium Finishes

Thermal Performance: A 6-chamber frame combined with a triple-gasket system achieves an exceptional heat transfer coefficient of 0.83 Uw for Ug = 0.5, perfect for extreme climates.

Superior Glazing: Supports massive glass thicknesses up to 54mm (STV technology) or 52mm (standard), allowing for high-spec triple or quadruple glazing.

Structural Integrity: Utilizes closed-section steel reinforcements to allow for oversized structures without the need for additional bars or mullions.

Seamless Aesthetics: We utilize V-Perfect technology for welding, ensuring nearly invisible corner joints for a flawless finish.

Acrylcolor Finish: Available with acrylcolor technology—a durable, vibrant, and scratch-resistant surface that is twice as hard as standard PVC.

Integrated Innovation

The S9000 utilizes STV (Static Dry Glazing), where the glass is bonded directly to the sash. This increases structural stability and security while preventing the sash from sagging over time. It is the ultimate choice for those who refuse to compromise between large panoramic views and maximum energy savings.
