Those who choose aluminum windows and doors expect a combination of sleek design, durability, and outstanding performance. With Decalu88, Deceuninck offers an aluminum system that combines these qualities into a contemporary and future-proof concept. The slim profiles, high insulation values, and refined finish make Decalu88 suitable for both modern new construction projects and high-end renovations.
The first thing you notice about Decalu88 is its flat exterior and minimalist look. Thanks to the narrow profile widths, maximum natural light is allowed in, while the overall design ensures a sleek, architectural look. Great attention has been paid to the details. For example, all drainage channels are concealed, and the entire series comes standard with hidden hardware. The result is a clean, uncluttered facade without any distracting elements.
Decalu88 also scores highly from a technical standpoint. Thanks to its integrated thermal insulation, optimized center hinges, and precisely installed seals, the system achieves excellent insulation values starting at Uf 1.0 W/m²K. Because the gaskets are installed during the manufacturing process—rather than on-site—proper installation and consistent performance in terms of wind and water tightness are guaranteed. Furthermore, the profiles—which consist of up to 70% of recycled raw materials—contribute to a lower environmental impact. In this way, Decalu88 combines high-quality performance with outstanding sustainability.
In addition to windows, the Decalu88 system also includes aluminum doors that combine the same sleek design with high usability and durability. The doors are available in a variety of high-quality styles and colors and can be fully customized, including glazing, milled lines, and trim profiles. Thanks to their durable coatings—available in any RAL color and Qualicoat-certified—the doors not only offer maximum design freedom but also retain their high-quality appearance for years to come. As a result, Decalu88 doors blend seamlessly with both modern and timeless architecture.
Aluminum is naturally strong, colorfast, weather-resistant, and low-maintenance. In addition, the doors are burglar-resistant and fully recyclable. This makes them a sustainable investment for both residential homes and commercial buildings.
A key innovation at Decalu88 is its patented anti-bimetal technology. Aluminum front doors can warp when subjected to large temperature differences, because the inside and outside heat up or cool down at different rates. This can cause problems when opening and closing the door. The anti-bimetal technology prevents this by using special thermal breaks that adapt to temperature fluctuations. This allows both sides of the door to expand and contract independently of each other, minimizing warping. As a result, even dark front doors that are exposed to direct sunlight for long periods continue to function optimally.
For projects that combine aluminum and PVC, Deceuninck offers a unique solution. The award-winning Elegant Abstract PVC system was developed with a look that perfectly complements Decalu88. Thanks to its architectural design—in which the opening sash lies completely flush with the frame—Elegant Abstract closely resembles aluminum while simultaneously benefiting from PVC’s excellent insulating properties. This allows architects and clients to strategically select the most suitable material for each application within a single project, without compromising on aesthetics. Because the visual difference between Elegant Abstract and Decalu88 is barely noticeable, a uniform appearance is created, while at the same time enabling significant budget optimization. This allows the end customer to combine the best of both materials and benefit from a cost-effective solution.
With insulation values starting at Uf 1.1 W/m²K, the option for triple-pane glazing, and a minimalist design, Elegant Abstract is the perfect complement to Decalu88. This allows architects and builders to effortlessly combine large aluminum facade openings with highly insulated PVC windows within a single project, without any visual discrepancies. The result is a harmonious whole in which design, comfort, and energy performance come together perfectly.
