In today’s market, agility is everything. Fabricators are under pressure to increase margins, reduce complexity and meet growing demand for high-performance aluminium systems, all without expanding headcount or holding costly stock.
The Decalu aluminium system from Deceuninck Aluminium has been designed from the ground up to help fabricators do exactly that.
With a modular construction, pre-gasketed profiles and a joined-up product offer that includes windows, doors and internal partitioning, Decalu is helping fabricators build a more scalable and profitable aluminium operation.
Modular by design, made for modern fabrication
At the core of Decalu is a platform-based approach to system design. Where traditional aluminium systems often require multiple profiles and unique components for each product type, Decalu simplifies manufacturing through shared parts, consistent principles, and intelligent engineering.
“The goal with Decalu was to give fabricators more with less,” explains Darren Woodcock, General Manager at Deceuninck Aluminium. “You can manufacture multiple window and door styles using the same key components, which cuts down on stock, speeds up production and reduces the potential for error.”
Thanks to this modularity, Decalu can be up to 40% faster to fabricate than many competitor systems. It also makes it easier to train production staff, quote jobs, and manage factory workflows.
Every Decalu system is pre-gasketed as standard, using co-extruded EPDM gaskets inserted during profile manufacture. This not only saves valuable time on the factory floor, but also eliminates gasket shrinkage, one of the leading causes of site call-backs.
Flush performance, future-proofed
Among the most popular products in the Decalu range is the Decalu88 Flush Casement, which has gained significant traction across both newbuild and home improvement sectors since its launch.
Available in side-hung, top-hung and fixed configurations, the system delivers a sleek, flush appearance with slim sightlines and U-values as low as 0.8W/m²K when triple-glazed. Even with standard double glazing, the system achieves 1.2W/m²K, comfortably meeting current regulations and helping future-proof fabricators as energy standards continue to rise.
“The Decalu88 Flush Casement gives fabricators a product that ticks every box: design appeal, thermal performance, and ease of manufacture,” says Darren. “It’s a perfect example of how the Decalu platform can support commercial growth through practical, real-world benefits.”
One system, many opportunities
A key advantage of the Decalu platform is its ability to support a complete product range underpinned by consistent design and fabrication principles.
From bi-folding doors and lift-and-slide systems to the Encasa internal door and partitioning system, Decalu enables fabricators to offer a joined-up aluminium solution, all while operating from a single, simplified system base.
Encasa, in particular, is opening up new, high-margin opportunities. With 34mm sightlines and a clean steel-look aesthetic, it’s ideal for internal glazing, pivot doors and sliding partitions, all manufactured using familiar Decalu processes.
For PVC-U fabricators looking to diversify into aluminium, this compatibility is especially valuable. Decalu systems use a PVC-U-style Eurogroove, share a similar fabrication logic, and are backed by Deceuninck Aluminium’s integrated technical support team, now aligned across both aluminium and PVC-U divisions.
“There’s a real opportunity for fabricators to grow their aluminium offering without starting from scratch,” Darren adds. “Decalu makes that transition smoother, quicker and more profitable.”
Ready to scale
Deceuninck Aluminium has further strengthened its support with UK-based profile stockholding, reducing lead times and helping fabricators plan with confidence. A growing range of colours, including marine-grade and dual finishes as standard, ensures even greater flexibility at the point of sale.
With performance-led product design, modular efficiency, and a complete support infrastructure behind it, Decalu is more than a system; it’s a platform built to power growth.
