SM90 Interior Window Series

　　1. According to the principle of siphon, a sealing strip is used to form an independent isobaric compartment on the window, and a stepped hidden drainage is designed. The fan adopts a drip line design and an independent drainage channel to form a complete isobaric drainage structure, avoiding rainwater infiltration.

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

　　3. Design a dedicated glass cushion block, reinforced with nylon material for stable load-bearing design, and installed diagonally to prevent the glass fan from sagging.

　　4. Design a dedicated glass pad cotton to improve the insulation performance of the entire window and avoid condensation on the window during low temperature and high humidity weather.

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

　　6. Developed 39mm multi cavity finned PA66GF25 insulation strip, with a wall thickness 40% thinner than traditional insulation strip, which can effectively block heat conduction. The indoor and outdoor aluminum alloy and insulation strip are combined together by rolling composite method, and the water vapor separation pressure adhesive strip effectively separates the indoor waterproof chamber from the indoor airtight chamber.

　　7. The middle sealing strip uses soft and hard co extruded foam rubber strip, with a slope design of 13.5 °. Using EPDM and soft hard co extruded foam rubber strips, the three seal structure effectively reduces heat loss caused by air convection.

　　8. The corner assembly uses pin corner codes and built-in guide grooves. Through a special guide adhesive design, the two-component adhesive effectively reaches the inner corners, with high strength, non fragility, precision of 30 threads, natural flatness, and greatly improved overall efficiency.
