Frame shapes.
Always the slenderest frames.
Narrower frames immediately deliver glass areas some 15% larger than those achieved by other manufacturers: for better daylighting and brighter spaces.
“Please do not specify windows for your home as a whole, but design them for each individual space.”

Lounge windows from Finstral.
We do everything ourselves – from development and production to installation and support. Finstral ranks as one of the very few window manufacturers to offer everything from a single source.
Do you just want to inspect, touch and try out our products? At the Finstral Studio, you will find a wide range of windows and doors. Along with expert answers to your questions.
Windows are investments for decades. Which makes intelligent design all the more important. The diversity of design and functional options is far greater than you can imagine.

At a glance.
The lounge is the central living space in your home and its windows are subject to accordingly high requirements. Finstral helps to craft solutions offering an ideal combination of daylight, views and atmosphere. The size, number and position of windows are tailored to the space and its intended use. Drawing on individually combinable materials, finishes and details, Finstral is able to precision-manufacture every single window – as a perfect and technically intelligent match for the space.
Our detailed catalogues for windows/glass walls and doors offer you comprehensive details of our wide-ranging product portfolio. You can view them online and download them at Prospectuses · Finstral. We should also be glad to send them to your home free of charge.
You can view Finstral windows at our Finstral Studios or at the premises of one of our approx. 1,000 dealer partners throughout Europe. Use our dealer search at finstral.com/dealer-search to find a site in your vicinity. You can, on request, arrange either a meeting there or a home visit.
Delivery and installation times depend on the specific project – the number of windows, mounting method, on-site situation etc. Binding dates for delivery and installation will be agreed with you a few weeks in advance. For window replacements, installation takes approx. 1¼ to 2 hours per window, depending on the mounting method. For further details, please visit: Installation - Finstral Planner.
That depends on the method. In many cases, we can adopt a minimally invasive procedure. For a window replacement, we then need only around 2 hours per window – all without any noise, dirt or scaffolding.
