Wood is natural and ecological material
Renewable resource
Precise technology for processing raw material
Wood is a heat insulator at an affordable price
Possibility to repair defects resulting from unprofessional use, obtaining a high-quality final effect
Wood is suitable for all materials; possibility to choose from a wide selection of top glazing sprays
In wooden windows it is possible to renew the top glazing coat after a certain period of ageing using a simple coating method
No need to imitate anything


Three-layer glued laminate ensures perfect product durability and stability in all directions and under any temperature and humidity
Wood has better strength characteristics in all directions of the frames and wings
Variability of shapes of the final products upon the designers, architects or customers requirements
Finishing shop with a controlled paint drying process we are one of the few manufacturers to apply a relatively complicated process of high-quality SIKKENS surface finish top surface finish in order to achieve the maximum surface quality - 4 layers of surface finish:
- Deep impregnation protects against penetration of humidity; in the case of a deep notch it protects the wood against humidity, decay, parasitic fungi and blue stain
- Colour impregnation sets the colour tone pigment base
- High-pressure sprayed 150m glazing layer
- High-pressure sprayed 150m top glazing layer
Latest trends in the manufacture of wooden windows
Offset glazing bar no unaesthetic space between the surface of the wing and the glazing window bar


Rounded edges ensure long life of the surface finish and improved coating earlier designs had sharp edges
Brand-name peripheral hardware for increased security
- Basic features
- Four-position handle closed, open, micro-ventilation and ventilation
- Two safety points on one-wing windows
- Four safety points on two-wing windows
- Safety catch to prevent windows from dipping or in the event of faulty handling
- DONAU THERMO drip moulds new modern shape of framed and winged drip moulds from anodized aluminium combined with plastic. It prevents the occurrence of a thermal bridge in the lower part of the window and prevents condensation inside the wooden profile as a result of the surrounding conditions and construction conditions
Window thickness profile of 68 mm and 78 mm
