JN70 内开内倒

下沉式隐藏排水结构，避免雨水倒灌。型材拼接采用德国卫仕双组角注胶工艺，更为美观、灵活，且严丝合缝。辅助系统采用全胶条、加厚加宽胶条、隔热保温。

The sinking type hides the drainage structure to avoid rainwater backflow. The profile splicing adopts the German Weishi double-group corner glue injection process, which is more beautiful, flexible, and tightly seamed. The auxiliary system adopts full rubber strips, thickened and widened rubber strips, and heat insulation.
