Energy-efficient window design innovation makes waves in self-build specification

Sustainability Tue, Oct 1, 2024 2:20 PM

The development of a new, ground-breaking frame innovation is set to transform the thermal performance of sash windows and make waves in the self-build market.

The ThermoVFlex system, developed in partnership by polymer products manufacturer REHAU and sash windows specialists Roseview Windows, allows homeowners to enjoy more energy-efficient frames without the cost of specialist glazing.

Crucially, this improved thermal performance is realised through the frame, rather than the glass, allowing for a u-value of 1.2 W/m2K without triple or vacuum glazing – the first sash window to do so.

Using the REHAU-patented ThermoVFlex system, self-builders can cut costs product costs while also allowing for more options on window design, as Keane Grantham, Marketing Manager at Roseview Windows, explains.

"Energy efficiency is becoming an increasingly important factor for customers in the self-build market, but they still want a variety of design options for their windows," he says. "Currently, we recommend that new build projects aim for a U-value of 1.2 W/m²K to futureproof and stay ahead of any potential updates to the Future Homes Standard or any further environmental legislation.

"However, current methods of achieving this performance level in sash windows can be expensive for self-builders while also restricting the design and aesthetic options available, such as astragal bars, safety glass, and other traditional patterns. This is why the ThermoVFlex system is so crucial; it enhances the frame’s overall energy efficiency without compromising the appearance of the finished window."

The ThermoVFlex system is currently used by Roseview to manufacture its Heritage Rose and Ultimate Rose sash windows. With the innovation representing a paradigm shift in frame design, Russell Hand, Head of Windows at REHAU UK, feels it has a large role to play in making UK homes more energy efficient.

“It is commonly known that the UK’s housing stock is among the draughtiest in Europe,” he concludes.

“As the Committee on Climate Change has previously made clear, decarbonising new and existing homes will be vital to achieving net zero decarbonisation goals.

We pride ourselves on being a whole systems provider and hope we can make a major impact in this ongoing journey to greener homes. Providing innovations such as the ThermoVFlex system to the self-build market and beyond will be key to this.”
