1. Window type technical parameters: multi-chamber three-way seal, window frame thickness 97.1mm, glass thickness 5+20A+5;
2. Whole window performance: flame retardant level B1, energy saving factor U value < 2.2-2.3 (w/.k), sound isolation level 6 (35-45dB), air tightness level 8 Q1 < 0.5 (m_/m.k), water tightness level 6 (Pa), air pressure resistance < 9 (KPa);
3. Micro-ventilation design, anti-theft, anti-insect and ant, comfortable and safe;
4. Multi-chamber PA66GF25 nylon strips and profiles are filled with polyurethane foam polyester as needed to increase the heat insulation performance of the frame.
5. EPDM soft and hard co-extruded micro-foam adhesive strip with automobile grade configuration can achieve good sealing performance.
6. Opening fans and window frames are multi-point foot grouping using self-developed multi-kinetic corner codes. After glue injection, the whole window is stable and has superior performance.
