    Reduce energy consumption of cold and hot air convection by filling polyurethane foam

    In extremely cold regions, the winter lasts for a long time. To meet the energy-saving requirements of buildings, our doors and windows are filled with polyurethane foam, effectively reducing the impact of outdoor cold temperatures on indoor environments.

    The first sealing process

    Isothermal structure design and four sealing processes complement and complement each other

    All PA66 nylon insulation strips are designed on the same vertical line to ensure the same isotherm, making the product's sound insulation and thermal insulation performance more outstanding. Combined with four sealing processes, it better solves the problem of indoor insulation and thermal insulation
