The most important feature of VIKNALAND window systems
– complete adaptation for temperature variations on the territory of Ukraine. Window – the design is initially mobile, “breathing”. In winter, the window profile becomes more fragile and brittle, in the summer, after heating, – soft and supple. Therefore, reliable profile and high-quality professional installation play a decisive role in the long-term operation of windows. And the VIKNALAND profile is designed according to Ukrainian weather conditions.
