Only wooden windows provide the pleasure of communing with healthy, natural wood. Although there are technologies that can imitate wood, they are no match for the original. Various types of wood prepared by 21. offer a wide range of different aesthetic experiences, which can be further modified through the use of a wide range of different coloured protective varnishes. 21. offers native wood species, such as pine and oak as well as exotic wood such as meranti.
Wooden windows are made of a material that naturally provides excellent properties in terms of acoustic insulation, especially thermal insulation. With wooden window systems, it is possible to meet the requirements of new construction and even significantly exceed the requirements for passive construction. Wooden windows can be used as a key element in reducing heating bills for houses, apartments and public buildings.
Wood is a durable material, thanks to which an investment in wooden windows is a guarantee for years. All wooden windows manufactured by 21. are covered by a five-year warranty. The raw material used and the technologies used in production, including ecological TEKNOS varnishes, minimize the typical risks associated with window warping and loss of functional properties. The maintenance requirements of wooden windows do not go much beyond what is necessary for other types of windows.
Choosing wooden windows means caring for the environment. The raw material used for their production is renewable. Each tree cut for production is replaced with new trees. 21. only use FSC-certified wood. The production process itself is also much more ecological, as it uses a minimum amount of harmful substances, and wood processing is less harmful to the environment than PVC or aluminium processing.
