Decalu88 Flush Casement: A system built for performance and longevity

Since its introduction to the market, the Decalu88 Flush Casement has proven itself a durable and efficient aluminium window system.

Since its introduction to the market, the Decalu88 Flush Casement has proven itself a durable and efficient aluminium window system.

Designed to meet the needs of fabricators, installers, and homeowners, the Decalu88 Flush Casement combines advanced technical features with aesthetic appeal, making it a standout choice for modern and traditional properties alike. 

Design versatility

The Decalu88 Flush Casement offers a seamless flush design, ensuring a contemporary aesthetic while maintaining compatibility with heritage-style projects. Its slim sightlines allow for more natural light and an enhanced visual connection with the outdoors.

But its design is more than skin deep. “The Decalu88 Flush Casement has been engineered to deliver on performance, not just looks,” says Alex Holbrook , Sales Manager for Deceuninck Aluminium.

“It’s a system that balances aesthetics with real-world practicality. It’s this balance that has made it such a popular choice across diverse project types.” 

A key feature of the Decalu88 is its flexibility in fabrication. Available in a variety of configurations, including side-hung, top-hung, and fixed frames, the system supports multiple project needs without compromising its core performance. 

Thermal efficiency that exceeds standards

With increasingly stringent building regulations, thermal efficiency is non-negotiable. The Decalu88 Flush Casement delivers U-values as low as 0.8W/m²K when triple-glazed, far exceeding regulatory requirements.

This level of performance is achieved thanks to Deceuninck Aluminium’s ThermoFibra technology and a carefully designed thermal break, which minimises heat loss and maximises energy savings. 

“Energy efficiency is at the forefront of what homeowners and developers are looking for,” Alex explains.

“The Decalu88 has been designed with this in mind, providing a solution that not only meets but exceeds expectations. It’s a system that helps fabricators and installers differentiate themselves in a competitive market.”

In addition to its thermal credentials, the system is also designed for acoustic performance, offering effective noise reduction in both urban and rural settings.

Ease of fabrication and installation

One of the standout features of the Decalu88 is its streamlined fabrication process. Designed with fabricators in mind, the system reduces manufacturing complexity through its modular design and pre-fitted hardware options.

This simplicity translates to faster production times without compromising quality.

The system’s ease of fabrication is matched by its installation efficiency. Pre-gasketed profiles and clip-on beads reduce time on-site, allowing installers to complete projects more quickly and efficiently.

“Time is a critical factor for both fabricators and installers,” Alex notes.

“The Decalu88 has been developed to streamline operations and boost efficiency. From the factory floor to the installation site, every detail has been considered to make the process as straightforward as possible.”

Durability and sustainability 

The durability of the Decalu88 Flush Casement is another key strength. Manufactured from high-quality aluminium, the system is built to withstand the test of time, even in challenging environmental conditions. 

Its powder-coated finish is designed to resist corrosion, ensuring it maintains its appearance and functionality for years to come.

Sustainability is also a core consideration. Aluminium is infinitely recyclable, and the Decalu88 system is designed with this in mind. This focus on sustainability aligns with growing industry and consumer demands for environmentally responsible building materials. 

“Durability and sustainability go hand in hand,” says Alex. 

“The Decalu88 is not only built to last but also designed to contribute to a more sustainable future. For many of our customers, this dual benefit is a deciding factor.”

Real-world success 

Since its launch, the Decalu88 Flush Casement has been specified for a wide range of projects, from high-end residential developments to commercial refurbishments. Its ability to deliver consistent performance across varied applications has earned it a reputation as a reliable and versatile solution.

For fabricators and installers, the system’s reliability translates to fewer callbacks and greater customer satisfaction.

For end-users, it offers peace of mind, knowing they’ve invested in a high-performing product that enhances their property. 

Alex adds, “The feedback we’ve received has been overwhelmingly positive. Installers appreciate the time-saving benefits, while homeowners value the combination of aesthetics and performance. 

“It’s a system that delivers on all fronts.”

Looking ahead

As market demands continue to evolve, the Decalu88 Flush Casement is well-positioned to remain a leading choice in aluminium window systems. 

Its combination of technical excellence, design versatility, and sustainability ensures it meets the challenges of modern construction while setting a benchmark for future innovation. 

“With the Decalu88, we’re not just responding to market demands—we’re anticipating them,” Alex concludes.

“It’s a product that embodies what Deceuninck Aluminium stands for; innovation, quality, and a commitment to delivering value to our customers.”
