In modern architectural design, windows are not only important channels for lighting and ventilation, but also key elements for maintaining indoor comfort and energy efficiency. As an energy-efficient window type, the sealing performance of double inner opening thermal insulation system window is directly related to the indoor insulation, sound insulation and waterproof effects. So, how does the double inner opening thermal insulation system window ensure its sealing performance?First of all, the double inner opening thermal insulation system window adopts a multi-pass sealing structure in design. Usually, this type of window will be equipped with three or more sealing strips, which are not only made of excellent materials and strong weather resistance, but also precisely designed to ensure that an effective sealing line is formed when the window sash is closed. In particular, the second seal, that is, the overlap between the isobaric strip and the thermal insulation strip, is crucial. Effective overlap can greatly enhance air tightness and water tightness, and prevent the penetration of external air and moisture.Secondly, the selection and installation of thermal insulation strips are also the key to ensuring sealing performance. High-quality thermal insulation strips not only have excellent thermal insulation effects, but also can enhance the overall strength of the window frame, thereby improving sealing performance. During the installation process, the insulation strips need to be precisely matched with the window frame and sash to ensure seamless docking. In addition, some high-end double inner opening thermal insulation system windows will also adopt the design of equal-width glass sash insulation strips and main frame insulation strips, which can further reduce the thermal bridge effect and improve the overall thermal insulation performance.In addition to the sealing strips and insulation strips, the pressure line design and drainage method of the double inner opening thermal insulation system window also have an important impact on the sealing performance. The closed pressure line design can enhance the bite strength between the window frame and the window sash, thereby improving the wind pressure resistance and reducing the sealing failure caused by excessive wind pressure. The floor drain type hidden drainage design can effectively prevent rainwater from backflowing and keep the room dry.In addition, the double inner opening thermal insulation system window also needs to strictly comply with relevant specifications during the installation process to ensure that the gap between the window frame and the wall is fully filled. It is usually sealed with materials such as foam glue and sealant to further enhance the overall sealing performance.In summary, the double inner opening thermal insulation system window ensures its excellent sealing performance through multiple sealing structures, selection and installation of high-quality insulation strips, closed-end pressure line design, floor drain concealed drainage design and strict installation specifications.
