PSK Patio Door
Gealan S9000
The GEALAN S9000 system in its tilt-and-slide configuration (PSK) represents our response to the demands of modern, conscious construction. We've taken the proven and highly functional solution of PSK patio doors and elevated it to an unprecedented level of excellence. Achieving a remarkable thermal transmittance coefficient Uw as low as 0.73 W/(m²K), our system successfully meets passive house standards. Its exceptional properties result from the synergy of three advanced technologies that together create a unique premium market proposition, guaranteeing maximum thermal insulation, reliable structural stability, and timeless elegance that stands the test of time.
STV® Technology – Guaranteed Stability in PSK Sliding Doors
Can you imagine massive patio glazing that operates smoothly and precisely even after years of use? Static Dry Glazing (STV®) technology provides an innovative solution to one of the biggest challenges facing large sliding constructions – maintaining perfect geometry. Through permanent bonding of the glass unit to the PVC profile, the rigidity of the glass intelligently transfers to the entire door leaf. In practice, this means you can be confident that even door leaves up to 2.5 meters (8.2 feet) wide will maintain their perfect form and smooth operation for decades, eliminating typical problems with sagging or frequent hardware adjustment.
IKD® Core – The Secret to Energy Savings in the PSK S9000 System
Think about the comfortable warmth in your home and the real savings visible on your heating bills. That’s exactly what IKD® technology (Integrated Core Insulation) delivers. Instead of hollow chambers or standard steel reinforcements that conduct cold, we factory-fill the main profile chambers with specialized polyurethane foam. This treatment drastically reduces the thermal transmittance coefficient of the frame itself (Uf) to just 0.89 W/(m²K), meeting rigorous passive house requirements and potentially reducing your heating costs by up to 25% compared to standard window solutions.
Acrylcolor® Coating – Durability and Aesthetics in Premium Class
Acrylcolor® represents a time-tested, advanced finishing technology that gives joinery exceptional durability and noble appearance. Through the co-extrusion process, the white PVC profile core permanently bonds with a layer of colored acrylic glass (PMMA). Unlike standard foils or coatings that can peel or fade, Acrylcolor® creates a uniform, integrated structure. Its surface is twice as hard as PVC, providing exceptional scratch resistance, while UV-protected color maintains its depth for decades. The silky smooth, non-porous coating prevents dirt accumulation, making maintenance of your sliding patio doors surprisingly simple.
Perfect Thermal and Acoustic Insulation – Your Private Haven
The foundation of the GEALAN S9000 system is its thoughtfully designed six-chamber construction with a frame depth of 82.5 mm (3.25 inches), creating an effective barrier against heat loss and unwanted noise. Moreover, we’ve implemented an innovative triple sealing system using EPDM gaskets. The third, central seal not only enhances thermal insulation but also creates a “dry chamber” that protects hardware from moisture, ensuring longer lifespan and reliable operation. The substantial frame depth accommodates energy-efficient triple-glazed units up to 54 mm (2.13 inches) thick, while acoustic insulation reaching 47 dB effectively reduces busy street noise to a comfortable whisper.
Intelligent PSK Mechanism – Convenience and Space Efficiency
The tilt-and-slide PSK system intelligently combines the advantages of traditional balcony doors with the convenience of sliding solutions. The mechanism operates intuitively: with one movement of the handle, you tilt the leaf for secure ventilation, then smoothly slide it along the fixed glazing. This solution saves valuable space in your living room or bedroom that would normally be occupied by an inward-opening leaf. Our PSK sliding doors also represent security – the construction resists forced entry from outside and can be equipped with anti-burglar hardware certified to RC2 resistance class, providing the highest level of protection.
Universal and Versatile Applications – Solutions Tailored to Your Needs
Whether you’re building a modern villa or renovating an existing property, the GEALAN S9000 PSK system answers contemporary architectural requirements. In single-family homes, it creates spectacular openings to patios or gardens, flooding interiors with maximum natural daylight. In premium apartments, it optimally illuminates spaces without consuming valuable floor area. Thanks to its excellent thermal performance, it’s also the ideal choice for energy retrofitting, significantly improving a building’s energy balance and meeting the highest requirements of international energy efficiency standards including EnEV and BREEAM certifications.
What Sets the GEALAN S9000 PSK System Apart from Other Solutions?
The secret behind the S9000 PSK system’s exceptional parameters isn’t a single innovation, but rather the market-unique combination of three advanced technologies. The synergy between Static Dry Glazing (STV®), thermally insulated core (IKD®), and Acrylcolor® coating achieves levels of dimensional stability, thermal insulation, and durability unavailable in standard PSK systems. While typical energy-efficient patio doors focus on basic functionality, GEALAN goes a step further. By choosing S9000 PSK, you’re investing in the most refined and efficient solution in its class – the ideal choice for discerning clients who value functionality but refuse to compromise on premium quality and energy efficiency.
