With the development of environmentally safe and energy-efficient construction of houses, people are increasingly paying attention to reducing heat losses. We offer passive high-performance windows, which meet the highest international requirements of passive windows. Passive houses are a look to the future and a house with high energy efficiency. The main properties of passive houses are excellent thermal insulation, air-tightness, return of heat from the exhaust air and quality windows and doors with low energy consumption. We offer passive windows that open both inward and outward. As the test results show, the U value is 0.59, for profile IV 90 - 0.62 for passive Top Swing windows.
