With low U-values, sleek aesthetics and exemplary sustainability credentials, Deceuninck is redefining expectations with a new, composite, tilt and turn window system for the commercial sector.

With homes accounting for around 14% of the UK’s CO₂ emissions and utility bills remaining high, energy efficiency is a key consideration when building new housing schemes.

Achieving U-values as low as 0.7W/m²K, Deceuninck’s ultra energy-efficient tilt-and-turn window system, Elegant, exceeds current building regulations to future-proof commercial projects.

Developed specifically for the commercial sector and ideally suited to medium to high rise applications, Elegant has also been designed to require less energy to recycle at end of life. This forms part of Deceuninck’s closed loop approach, in accordance with its participation in the Science Based Targets (SBTi) carbon reduction scheme.

A match for aluminium

With a contemporary, minimalist aesthetic, Deceuninck claims that the composite PVC-U and aluminium product is a strong challenger to the full aluminium systems it emulates, while its modular design maximises design flexibility and minimises stockholding.

“Elegant makes up one of the ‘four pillars’ of our commercial proposition to customers, alongside our 2500 and 2800 series, aluminium offering, and building products range,” says Peter Dyer, head of commercial at Deceuninck.

“With the backing of our wider sustainability strategy, it’s an extremely viable alternative to some of the larger aluminium-specified projects because it looks great but also delivers exceptional through-life performance. In addition, it’s also less energy intensive to recycle post-consumer,” he continues.

“Everything about it – from manufacture, to performance, to end-of-life – is geared to reduce carbon emissions. It creates big opportunities for fabricators, installers and developers because, with U-values as low as 0.7W/m²K, it delivers a far higher level of thermal efficiency than aluminium, at a cost-effective price point.

“This means that Elegant can be pitched to specifiers as an added-value option, creating opportunities for fabricators and lowering costs for developers, all while delivering a better solution to the end-user,” Peter adds.

A 76mm system with a ThermoFibra glass fibre sash, Elegant incorporates Forthex, Deceuninck’s extruded insulated thermal reinforcement. This negates the need for traditional steel reinforcement, thanks to steel wires embedded in a low-density insulating foam core.

Windows manufactured using ThermoFibra and Forthex are as strong as steel reinforced windows but are 30% more thermally efficient with 40% savings on materials and weight. They are also 100% recyclable.

With slim sightlines and contemporary minimalist features, Elegant creates a strong architectural aesthetic in an advanced, low maintenance and energy efficient composite system.

This look is achieved with Decoroc, a durable foil which creates the appearance of powder-coated aluminium. Said to be a popular choice in commercial applications, Decoroc is designed to be cost-effective, scratch and impact resistant. Easy-to-clean, Decoroc is available in 16 colours and finishes which span Deceuninck’s aluminium and PVC-U ranges  for maximum flexibility.

A future-proofing approach

With energy efficiency and sustainability increasingly dominating the future of construction product manufacture, the launch of Elegant heralds a genuine step-change in the development of viable window solutions for the commercial sector.

With U-values that far exceed current building regulations, Elegant offers a level of thermal efficiency that not only meets today’s requirements but also anticipates the tougher standards of tomorrow. This future-proofing approach ensures commercial specifiers, developers, and installers can deliver projects that combine sustainability with long-term value.

And with a modular design philosophy that delivers both versatility and manufacturing efficiency, this flexible window enables fabricators to streamline production while offering clients a wide range of aesthetic and performance-led solutions.

“With Elegant, we’ve really raised our game in the commercial sector,” adds Peter. “It strikes a perfect balance between value, performance and aesthetics that is currently unmatched in that marketplace.”

“It’s setting the standard for a new generation of low maintenance and energy efficient products, which position Deceuninck and our customers for a future defined by energy efficiency and sustainability.

“That’s an opportunity not to be missed, for commercial fabricators, installers – and developers,” he concludes.
