Energy-saving sliding door and window

NIW50F series energy-saving inner opening inner window

1. This system adopts polyamide-nylon plus glass fiber insulation polymer as the heat-insulating strip of the heat-insulating strip, and the inner and outer profiles adopt the hollow-back structure, which can effectively reduce the resonance effect of sound waves and prevent the sound from spreading. At the same time, due to the separation of the inner and outer profiles, the surface treatment and color of the indoor and outdoor profiles can be flexibly configured according to the needs.

2. The opening fan system forms a multi-chamber structure through the eagle rubber strip and the T-shaped heat insulating strip, and the outer chamber communicates with the outside through the air guiding and drainage device to form an isobaric chamber, which significantly improves the airtightness and watertightness.

3. The frame and fan of the system adopt 45-degree group angle, and stainless steel reinforcement code pieces are set at the corners of the group. The positioning is accurate, the connection is reliable, and the appearance is simple and beautiful.

4. The system is people-oriented and has child safety devices to enhance the safety of high-rise use.
