Traditional craftsmanship meets the latest technology

Manufacture of

your quality windows

Ambitious and sustainably-built architecture needs building materials like wood. It is an extremely hard-wearing raw material with the ideal properties in terms of its physical structure. Working with wood not only makes sense and is efficient, it is also unavoidable for energy-efficient building, healthy living and for houses with character. The native timber we use comes from the healthy forests of the Suwalki Lake District, where we process it in the local region to create our high quality products.

At BARTYN, we see our craftsmanship as bespoke work. Our windows are a symbol of quality and tradition. Combined with future-oriented innovation, these two elements form the basis of the success story of our company. Despite the high degree of technology used at BARTYN, there is no getting away from the fact that the construction of wooden windows is still to a great extent a matter of manual processes. This requires highly-trained and experienced employees. In the manufacture of our wooden windows at BARTYN, a highly-qualified team of employees with fine instincts for their work and decades of experience are responsible for building our unique products. The windows they construct with their professional skill and the use of the latest technology are available in a range of sophisticated versions, and can also be manufactured according the individual wishes of our customers, in order to fulfil the requirements of any architectural style. We manufacture more than 10,000 windows every year.  Around 80% of these are sold on the international market. 


Live and love the individual character of your wooden windows from BARTYN.

Wooden windows

We at BARTYN love wood – this living material, with its individual charm and natural elegance cannot be matched by any other raw material. It's no wonder that wood is the traditional and most well established material for the construction of windows. Wood is an energy-saving, natural and renewable raw material, with a diverse range of possible uses. We design and create the dimensions for your windows on an individual basis, according to your needs and wishes – both windows with a historical character and those with a contemporary style. In doing so, we consider outstanding properties in terms of thermal insulation, quality in respect of air and watertightness, sound insulation and mechanical load bearing to be an absolute must.

Wood-Aluminium windows

Wood-Aluminium windows are the most exclusive windows on the current market, as their design and the technology used are of an incomparably high standard. This combination of materials offers the respective advantages of each of the materials, saves energy and provides security: On the exterior, a maintenance-free aluminium shell acts as a protective layer meaning that maintenance and painting are no longer an issue. On the interior, the warm, living feeling of wood in an elegant design provides exceptional thermal insulation values. A system is thereby created that meets the highest standards both in terms of technical performance and aesthetics. 
Painting and maintenance of the outside of the windows? Not anymore! Simply enjoy the view and leave the rest to your windows.
