This window uses high-quality TPE EPDM composite strips and high-strength nylon PA66 insulation strips, which give the window stronger insulation and sealing, thereby effectively saving energy and land consumption. The slim window frame maximizes the use of natural light while improving the field of vision. The sliding design makes it more advantageous in terms of space saving, and the tilt-in design allows the window to be opened even on rainy days for better ventilation. Especially for families with children and pets, the tilt-in design greatly reduces the safety hazard of falling from buildings.
