The warmest certified passive window is designed for passive and low-energy construction. Thanks to modern technologies, the windows have excellent thermal insulation parameters and are characterized by above-average air and water tightness, being a kind of shield that protects us against unfavorable external conditions. The Passiv-line Ultra window can significantly reduce the demand for primary energy, which significantly improves the energy balance of the building.

Benefits of using this product:

• Energy efficiency – meaning a significant reduction in heating costs as the windows let more energy in than out,
• Definitely better thermal insulation,
• Minimizing the loss at the window tightness level due to the practically no air exchange with the window closed,
• Elimination of thermal bridges, even at the level of the frame and its contact with the glass,
• better acoustic insulation thanks to glued glass and a triple set of gaskets.
