REHAU’s ARTEVO Window System Now Fabricated in UK

REHAU’s largest window system ARTEVO is now being fabricated in the UK, giving architects, designers and specifiers the opportunity to incorporate large, high-performance polymer profiles that maximise natural light.

ARTEVO builds on the successful GENEO range with RAU-FIPRO-X material, enabling floor-to-ceiling heights up to 2.6 meters. Now available in a new ALUX colour that is virtually identical to aluminium, the system offers enhanced stability through integrated force zones that eliminate the need for steel reinforcements. Its steel-free frame is 40% lighter than previous models and may be fitted with sealed units up to 72mm thick when used in the flushed-mounted sash, while also able to achieve sound insulation RW of up to 48dB.

The Passivhaus-certified ARTEVO window system is now being fabricated in the UK by commercial installer and fabricator GRM Windows. According to, Richard Gambling, Managing Director at GRM Windows, the window system’s versatility, practicality and sustainability credentials greatly appealed to the company as it looked to expand its frame portfolio.

“We wanted to be able to fabricate larger window profiles in polymer that would maximise natural light,” he explains. “This is vital in modern architectural design, but it cannot come at the cost of the frame’s thermal performance. ARTEVO’s efficiency in heat retention, combined with its lightweight construction that makes it easier to handle and install than other similar frames, meant it could provide the best of both worlds for our customers.

“The fact steel reinforcements are not needed was another key reason behind our decision to add ARTEVO to our window portfolio, as this meant we could streamline the fabrication process. We were also impressed by the frame’s overall sustainability – we know that each profile contains up to 75% recycled content and that recyclates are being used in the ARTEVO’s glazing beads. Being able to demonstrate sustainable practice is becoming increasingly important to securing project work, so having these provable green credentials easily available is undoubtedly a major benefit.”

ARTEVO is available with a fully recyclable Low-E foil, a patent pending thermal insert technology developed by REHAU’s engineers, allowing the system to achieve a u-value of up to 0.81 W/.m²K. Pre-inserted within the chambers of the window profile and replacing traditional foam thermal inserts, its V-shaped, reflective foil can also reduce heat radiation by up to five per cent while preventing convection within the profile chambers.

“ARTEVO is designed with architectural freedom in mind,” says Russell Hand, Head of Product & Technical at REHAU UK. “It offers slimmer profile sizes down to 80mm while increasing frame performance, ensuring it can be used for large spans without compromising on a building’s design or performance priorities as a project nears completion. “Our commitment to added value is why ‘evolution’ features in the product’s name, as we’ve taken everything that made our GENEO system a success and improved upon it. We are confident GRM Windows will see growing demand for the ARTEVO system going forward, offering the best possible combination of performance and design sensibilities for the commercial market and beyond.”
