ZB90 Narrow Bezel Inward Opening Window Series

　　1. The visible surface of the profile is reduced while the wall thickness is increased to 2.0mm, effectively increasing wind pressure resistance.

　　2. Based on the siphon principle, the sealing strip creates an independent pressure-equalizing chamber within the window frame. The fan features a drip line design and independent drainage channels, forming a complete pressure-equalizing drainage structure to prevent rainwater infiltration.

　　3. A dedicated glass pad is designed, using nylon material to enhance load-bearing stability. Diagonal installation prevents the glass fan from sagging.

　　4. The pressure rib design is closed, enhancing overall thermal insulation and wind pressure resistance.

　　5. A new 35.3 multi-chamber PA66GF25 thermal insulation strip with fins is used, which more effectively blocks heat conduction. The indoor and outdoor aluminum alloys and thermal insulation strip are combined using a roll-forming composite method. The water-air separation pressure-equalizing strip effectively separates the outdoor watertight chamber from the indoor airtight chamber.

　　6. The intermediate sealing strip uses a co-extruded soft and hard foam strip with a 13.5° slope. Utilizing EPDM and co-extruded soft and hard foam strips, the triple-seal structure effectively reduces heat loss caused by air convection.

　　7. The corner brackets use pin corner brackets with built-in guide channels. Through a special adhesive guiding design, the two-component adhesive effectively reaches the inner corners, resulting in high strength, durability, 30 microns precision, a naturally flat finish, and significantly improved overall efficiency.
