FM86 Interior Window Series

　　1. Wall thickness 1.8mm.

　　2. The frame layer is flush, and the indoor and outdoor are parallel and integrated, effectively improving window energy efficiency. The square lines are simple and beautiful.

　　3. The frame adopts traditional open frame drainage, and the fan adopts drip line design and independent drainage channels to form a complete equal pressure drainage structure, avoiding rainwater infiltration.

　　4. The pressure line is designed in a closed form, enhancing the overall insulation and wind pressure resistance performance.

　　5. Both the frame and fan are made of 35.3mm PA66GF25 insulation strip, with a vertical isotherm design, effectively reducing the product's heat transfer coefficient.

　　6. Using a rolling composite method to combine indoor and outdoor aluminum alloys with insulation strips, and applying pressure adhesive strips for water vapor separation, effectively separating the indoor waterproof chamber from the indoor airtight chamber. The foam rubber strip and three sealing structures effectively reduce heat loss caused by air convection. The design allows the two-component adhesive to effectively reach the inner corners, with high strength, non fragility, precision of 30 threads, natural flatness, and greatly improved overall efficiency.

　　7. The middle sealing strip uses soft and hard co extruded foam rubber strip, which is made of EPDM and soft and hard co extruded

　　8. Use collision angle codes or pin angle codes for corner assembly, with built-in guide grooves and special adhesive guides
