Six months after its debut, Alunet Systems’ Aluna+ Window System is steadily gaining momentum within the aluminium fenestration sector. Launched at RAF Cosford in April this year, the system arrived at a time when the market had grown increasingly saturated with complex, over-engineered options that often-added friction for both fabricators and installers. Aluna+ was designed to take a different approach. Where much of the industry has chased innovation through complexity, Alunet took the opportunity to re-evaluate what efficiency could look like in practice. The result is a system that aims not only to meet current performance and compliance standards but to do so with fewer moving parts and clearer fabrication logic, attributes that have become increasingly valuable in today’s demanding commercial and residential project landscape.
At the centre of the Aluna+ design is a patent-pending universal sash and transom profile, developed to simplify stockholding and manufacturing while reducing overall system part count by more than 30%. The intention is to free up bench space, streamline assembly, and help fabricators retain cashflow, without compromising on technical integrity or visual impact. “The traditional mindset in aluminium system design often sees complexity equated with innovation,” says Chris Armes, Technical and New Product Development Director at Alunet Systems. “But for fabricators, complexity can slow production, inflate overheads, and introduce more room for error. With Aluna+, we wanted to deliver a system that does the opposite – one that makes aluminium fabrication feel as straightforward as it should be.”
While the benefits to fabricators are clear, Aluna+ has also been designed with end-user expectations and installer needs in mind. Clean, flush aesthetics and narrow sightlines are supported by solid structural credentials and built-in thermal efficiency. The system achieves U-values as low as 0.9 W/m²K when triple glazed, or 1.2 W/m²K with standard double-glazed units, a detail that not only enables compliance with Future Homes Standards but also provides flexibility for specifiers and installers to meet performance targets without requiring bespoke glazing solutions. Aluna+ is out the box Building Regulations compliant boasting no foam, no fuss thermal efficiency with performance being managed using engineered polyamide thermal breaks.
The system is currently available in casement, flush, and tilt-turn configurations, allowing it to adapt to a wide variety of architectural requirements and project types. Its retro fit modular sills and ancillary components enhance thermals further and provide yet more reductions in required stock and more than 5% in fabrication waste. A brilliant balance of innovation and practicality which offers a level of consistency that is increasingly important as whole-house aluminium packages become more common.
While Aluna+ was never positioned as a disruptor in the traditional sense, its impact has grown organically through word of mouth among fabricators seeking to reduce complexity and improve workshop efficiency. Chris continues, “We’re not trying to reinvent aluminium windows just for the sake of it. What we’re trying to do is listen to fabricators, to installers, to market forces, and design systems that genuinely respond to what fabricators and installers need right now. Aluna+ is a reflection of that thinking.”
Alunet has also made it clear that Aluna+ is part of a wider, long-term strategy. The system sits within the company’s broader Aluna product family, which includes Bifolds, Sliders, Lanterns, Rooflights, French, Entrance, and Internal Doors – all built with the same innovative fabrication ethos. This whole-house alignment is expected to be a major area of focus as the market continues to prioritise consistency across product ranges and suppliers.
