FM110 Double Internal Windows

　　1. According to the siphon principle, the window is formed into an independent equal pressure compartment using sealing strips, and a stepped hidden drainage is designed. The fan adopts a drip line design and an independent drainage channel to form a complete equal pressure drainage structure, avoiding rainwater infiltration.

　　2. 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.

　　3. Design specialized glass pads to improve the insulation performance of the entire window and avoid condensation in low temperature and high humidity weather.

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

　　5. Adopting a flat external screen window design scheme to enhance the insulation performance of the entire window. The gauze fan is detachable and highly practical.

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

　　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 with built-in guide grooves. Through a special guide rubber 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.
