What are the benefits of concealed drainage for system doors and windows?
In fact, the traditional drainage is that the profile opens two drainage holes to drain. If the rainfall is too heavy that day, these two drainage holes are likely to drain less, resulting in rainwater leakage from doors and windows. Working principle of concealed drainage of doors and windows: outdoor pressure will often be exerted on indoor under the action of wind, and rainwater will penetrate into indoor along this pressure. Sealing rubber strips are added in the center of window sash and window frame, the outer side is watertight, the inner side is airtight, and the outer side forms an isobaric chamber. The pressure in the isobaric chamber is equal to the outdoor pressure, which can prevent rainwater from entering the chamber and flowing out by its own gravity.
