HOME | About us


The DAREK company has been operating on the market since 1995. The production plant is located near Olsztyn in Dobre Miasto. It is located on a plot of 6.5 ha, where the production area covers over 4,000 m2. The latest machine park and the latest technologies in the window production industry apply.

Our staff consists of people with many years of experience and having the necessary qualifications guaranteeing the high quality of our products and services. The second production plant is located in the town of Kanie near Pruszków and has been operating since 2004. The production capacity of the plants is 470 window units per day. Such performance of the production lines satisfies us completely because we paid particular attention to the quality of our products and services and not as in most plants for quantity. At present, we can export our products to 3 countries of the European Union, such as the Netherlands, Germany and Norway.

As part of partnership-based cooperation, we care for the greatest satisfaction of our clients and contractors, wishing to permanently bind them to the company. We achieve this by maintaining an unchanging balance between the client’s interest and ours. Our innovative and quality impeccable products are arguments for our clients and partners in maintaining the optimal position on the market. It does not matter whether you are building new houses, renovating or renovating – the selection of the right windows plays an important role in the design phase of the building. The choice of window elements depends on what aspects, whether optical, technical or functional, are in the foreground.

In addition to classic solutions, windows and doors of any shape (circles, arches, trapeziums, triangles and others) and colors (veneered on one side or on the inside, veneered on both sides on a brown or white core, in a wide palette of wood-like foils) are made. The “DAREK” window and door factory is fully prepared for the use of the latest solutions in the field of PVC and ALU systems as well as fittings and composite glass.
Trying to stay ahead of the customers’ expectations, the offer is systematically extended by newer product solutions, examples of which can be introduced innovative solutions such as: IDEAL 8000 system (PVC system with aluminum overlays in any RAL color), HS lifting and sliding door system, window system and Passive House passive house or acrylic door in any RAL color.

The continued increase in thermal insulation requirements in recent years has forced profile manufacturers to make efforts to improve thermal insulation properties in systems. The aim of these efforts was to develop profiles whose heat transfer coefficient approaches the same coefficient as the one obtained in the case of glass. Attempts have been made to achieve this improvement without changing the existing depth of the structure. While this step brought yet a remarkable improvement when increasing the number of chambers to three, the further increase in the number of chambers did not lead to the expected results. The solution to this dilemma was brought by the construction of a completely new geometry profile with a depth of 70 mm and more. In this way, it was possible to obtain U values ​​of 0.7 W / m²K while using standard steel reinforcements.

In combination with thermal insulation glazing, Uf values ​​of 1.2 W / m²K and less are no longer utopian. The DAREK company already has windows and doors for sale with a heat transfer coefficient = 0.7 W / m²K. Wishing to meet the expectations of our clients, we would like to remind you that we have made windows from the beginning of our existence in any dimensions and shapes without additional costs associated with the purchase of non-standard goods, which certainly makes it easier for our customers to make a decision about the choice of PVC and aluminum joinery.
