Frame shapes.
From traditional frames or industrial-loft-style sashes to minimalist profiles – we can meet all your aesthetic and functional requirements.
Aluminium-uPVC windows: robust aluminium on exterior, perfectly insulated on interior.
Rich colours, optimum insulation.
“Sticking colour film onto uPVC profiles may be cheaper, but makes little sense in terms of functional performance. […] For dark colours, Finstral always uses aluminium facings, which are capable of withstanding far higher temperatures.”
Joachim Oberrauch
Finstral Board of Directors
Unlimited colour choice.
We always use aluminium to produce dark colours – unlike other manufacturers, who apply paint or film to uPVC frames. Aluminium remains dimensionally stable even at extremely high temperatures. Dark uPVC, by contrast, softens when it heats up to over 80 °C, which may cause the frame to deform.
For the aluminium exterior, you can choose from over 250 colours. Nine non-sensitive options are available for the interior uPVC finish.
Supreme insulation performance.
No window insulates better than a modern uPVC model. This is irrespective of any aluminium facing on the exterior. Finstral windows achieve top values of up to Uw 0.74 W/m²K and Rw 47 dB.
Exterior uniformity, interior diversity.
Finstral enables you to design your windows space by space. With an aluminium-uPVC model in the bathroom or children’s bedroom and an aluminium-wood configuration in the showpiece lounge. While the interior is always tailored to the particular occupancy, the identical exterior vouches for a uniform façade composition.

Solar protection.
There is a host of solar protection options on offer – from traditional hinged shutters and solar protection glazing to interstitial shading devices.
Long-lasting quality.
Not only should new windows be secure, weathertight and attractive, they should also last for decades. Which is why we do our utmost to maximise the service life of our products. And how? By doing everything ourselves: from developing the profiles to the aluminium powder coating and specification of installation standards.
Minimum 60-year service life.
The mechanical durability (repeated opening and closing) of Finstral windows is tested not for the standard 20-year period, but for three times as long. Thanks to their high-grade design, they can withstand over 60,000 tilt-and-turn cycles without damage.

The best of both worlds.
Finstral’s aluminium-uPVC windows comprise a highly insulating uPVC core and a robust aluminium facing. They thus combine the durability and colour variety of aluminium with a far superior thermal insulation performance than that offered by pure aluminium windows.
FAQ
How are aluminium-uPVC windows installed?
Aluminium-uPVC windows can be fitted using minimally invasive methods, e.g. by means of slide-in installation, which involves no noise, dirt or scaffolding and takes around one hour per window. Here, the sashes, hardware and gaskets are removed from the existing frame and the new frame is slid into place. Installation with the FIN-Fix mounting frame is recommended for new-build contracts. This is incorporated during the wet construction phase. The window itself is then fitted during the dry construction phase, i.e. after all the “messy” operations have been completed. This virtually eliminates any risk of damage.
How are aluminium-uPVC windows maintained?
As the coated aluminium facing is highly dirt-repellent, simply wiping it down with water suffices. During Finstral’s uPVC extrusion process, textures are directly embossed into the material and not – as with other manufacturers – simply stuck on as a film. The dirt-sensitive micropores in the profiles are also compressed. This delivers a homogeneous, scratch-resistant finish that prevents dust from settling.
How much do aluminium-uPVC windows cost?
Each window is unique and the price depends on many different factors: size, materials, glass, security options etc. For a personalised quote, please contact us at finstral.com/contact.
