Sash design
We offer sashes that are offset or semi-offset from the frame or that sit flush. Depending on the chosen model, the interior edges can also be more angular or curved.
Aluminium uPVC windows feature an uPVC frame and sash encased by external aluminium cladding. Modern uPVC shows on the interior and makes for an excellently insulated window core. The material’s sleek surfaces can also be easily customised with our range of colour coatings. On the outside, the metal cladding protects and provides impressive robustness. It can be coloured to match the interior or fashion a different finish. To find out more just read on or contact us to start your Neuffer journey today.
The Key Benefits
- Excellent insulation: thanks to uPVC’s precisely engineered structure and profiles that feature three gaskets, we offer very good sound insulation as well as Passive House certified aluminium clad windows with maximum energy efficiency.
- Low maintenance: due to the sleek wipeable nature of the interior face and the long-lasting external cladding, these windows can be easily cleaned and require minimal upkeep.
- Impressive protection: the strength, impact resistance, and anti-rust properties of the metal exterior ensure excellent protection against the elements and break-in attempts.
Glass seal
The glass seal ensures watertightness between the glazing and the sash that encases it. The weather-resistant aluminium shell with welded corner joints.
Reinforcement
Depending on the model, a steel or energy-saving carbon fibre reinforcement fully strengthens the structure.
Chambers
A varying number of insulating chambers that trap dense air slow heat loss.

Certificates & Quality Manufacturing
During production the metal cladding that externally protects our aluminium uPVC windows is anodised to ensure excellent anti-rust and anti-corrosion properties. It is then additionally powder-coated in the chosen colour of decor, which provides further protection as well as UV resistance. Thanks to these techniques we can therefore provide a 10-year guarantee on the metal surface of our aluminium uPVC windows, which makes for an excellent price to performance ratio. Alongside guarantees, some of the profiles, such as the twinset energeto 8000 and TwinSet energeto 8000 ED models, have been certified by the Passive House Institute as being particularly energy-efficient. The profiles have u-values below 0.8 W/(m²K), for example, and so greatly reduce utility bills as well as carbon footprint by helping to maintain an interior temperature that won’t exceed 25 °C for more than 10% of hours annually.
