Installation depth: 82.5 mm
Gealan S9000
Imagine the perfect morning. Outside, the city pulses with life, but in your living room, there's blissful silence. Sunbeams gently illuminate the interior, and you feel pleasantly warm, knowing your heating bills won't spoil this moment. This isn't a dream. This is everyday reality created by GEALAN S9000 passive house windows – the certified solution for those who demand absolutely uncompromising energy efficiency and comfort from their homes.
With a record-low U-value of just 0.71 W/(m²K) and the prestigious Passive House Institute Darmstadt certificate, this system sets new standards in energy-efficient construction. These are the ideal passive house windows for any prestigious investment where thermal comfort, peaceful tranquillity, and timeless aesthetics are priorities.
The GEALAN Technology Triad: Synergy of Innovation in Passive House Windows
What makes the GEALAN S9000 system so exceptional? It’s not a single feature, but the synergy of three proprietary, groundbreaking technologies. The combination of unmatched stability, intensive thermal insulation, and unrivalled colour durability creates a complete energy-efficient window that addresses the key challenges of modern construction in one system.
1. STV® Technology (Static Dry Glazing) – More Light, Greater Stability
Do you dream of large-format glazing that opens your home to the garden? STV® technology makes it possible. This patented solution permanently bonds the glazing unit to the sash profile. This means the glass weight is distributed evenly, allowing you to create stable large-scale window installations up to 2.5 metres high, eliminating the need for massive steel reinforcements. Your windows are lighter, slimmer, and let in more valuable daylight, whilst you forget about the risk of sagging heavy sashes and costly service visits.
2. IKD® System (Intensive Core Insulation) – Warmth Locked in the Heart of the Profile
How do you achieve the highest thermal insulation for windows? By filling the main chamber of the profile with special insulation foam during production. That’s the secret of the IKD® system. This solution, applied in a controlled factory process, reduces the thermal transmittance value of the frame itself (Uf) to a record-breaking 0.89 W/(m²K). For you, this means a simple benefit: even lower heating bills and the certainty that every element of your uPVC window works towards your family’s comfort.
3. GEALAN-acrylcolor® Surface – Lasting Window Colour That Defies Time
Your home’s aesthetics are an investment for years to come. The GEALAN-acrylcolor® surface guarantees they’ll remain unchanged. This isn’t ordinary foil or paint. It’s a 0.5mm layer of coloured acrylic glass (PMMA), inseparably fused with the PVC profile. The result is a uniform, perfectly smooth, matt surface that’s twice as hard as standard PVC. It’s completely resistant to fading, peeling, and scratching. Your energy-saving windows will retain their lasting colour and perfect appearance for decades, without the need for painting or renovation.
6-Chamber Windows 82.5mm: Construction for Maximum Thermal Insulation
At the heart of the system is the GEALAN S9000 profile with an installation depth of 82.5mm, whose six-chamber construction creates an extremely effective barrier against heat loss. The construction is complemented by an advanced triple sealing system (in the MD version). Its middle seal creates a so-called “dry chamber” that protects the hardware from moisture, guaranteeing years of trouble-free operation. Moreover, the possibility of using energy-efficient triple glazing units with a Ug value down to 0.5 W/(m²K) with warm edge spacer bars allows precise parameter matching to your project’s most stringent requirements.
Sound Insulation up to 51 dB: Quiet Windows for Your Home
Do you know the difference between the noise of a busy street and the silence that allows you to fully relax? It’s precisely 51 decibels. With this acoustic insulation performance, the GEALAN S9000 system offers the highest level of noise protection. Whether your home is in the city centre, near an airport, or railway line, you can enjoy priceless peace. This is your private comfort zone.
Complete GEALAN S9000 System: Windows, Doors and Lift-Slide Systems in One Style
Perfection lies in consistency. GEALAN S9000 isn’t just windows – it’s a complete window system platform that also includes entrance doors and large-format lift-and-slide systems (HST). This allows you to complete your entire project in one cohesive style, maintaining the same highest level of aesthetics, technical parameters, and quality. The system is available in over 50 colour variants, including the exclusive GEALAN-acrylcolor® palette and wood-effect Realwood® finishes, giving you unlimited design possibilities.
Passive House Certificate and Funding Programmes
By choosing GEALAN S9000, you’re investing in quality with objective confirmation. The certificate from the Passive House Institute Darmstadt – the most prestigious institution in this field – guarantees that the system meets the highest global standards for passive house construction and will achieve your building’s planned energy balance. Furthermore, the excellent thermal transmittance values qualify the system for various energy retrofit funding programmes available worldwide, allowing you to obtain attractive rebates on investment costs and making it even more cost-effective.
