The multi-upgrade for your home.

More daylight, more peace and quiet, more insulation, more security, more living comfort: a window replacement often improves far more than just the visuals. Modern Finstral windows combine functional performance with security, sound insulation, energy efficiency and aesthetic appeal.

The Finstral pledge.

Always from a single source. For uncompromising quality.

What makes Finstral windows so special? The fact that we model them as an integral system. The result is a perfectly coordinated window concept uniting aesthetic appeal, energy efficiency and durability.

Smart window replacement.

Finstral has innovated the minimally invasive slide-on and slide-in installation methods. The outcome? Window replacement in a maximum of two hours per window. Without noise, dirt or any need for tenants to vacate the building.

Multiple certifications.

Quality is something we can demonstrate, not just promise. Our products, installation methods and procedures are regularly inspected, making us one of Europe’s most certified window manufacturers.

Always nearby.

With 14 plants, 27 company-owned Studios and some 800 partners across 14 countries, we combine pan-European experience with face-to-face, on-the-spot counselling. We can thus provide you with reliable, end-to-end support, from design through to installation.

More light.

Slender frames and large areas of glazing will admit more daylight into your interior to lend your home a more open feel. Architecture, living quality and views will take centre stage.

Enhanced security.

Not only do new windows protect against wind and weather, they also make life far more difficult for burglars. Up-to-the-minute security features combine powerful protection with high design appeal.

Window replacement without dirt or noise.

Refurbishments usually spell building mess. Not with Finstral: our intelligent, minimally invasive installation methods generally allow us to replace your old windows in under two hours. With neither masonry works nor any elaborate preparations. Your furniture stays where it is and you carry on with your daily routine. Come evening, you will be back in your lounge – only with a nicer view. Thanks to your new windows.

Energiesparen, Fenster mit orangenen Hintergrund

Energy saving starts with windows.

Old windows are rarely either efficient or attractive. New Finstral windows kill two birds with one stone: premium-quality insulation glazing, thermally insulating profiles and best-practice installation will cut energy use by up to 20 %. Your new windows will be visible on your heating bill. And not only on your façade. Every replaced window will thus pay double dividends, benefiting both your energy profile and your home.
