The purpose of drainage is not only to ensure that the door and window frames do not seep water, but also to ensure that the cavity of the insulating glass is dry and does not generate water vapor, because the high temperature after rain can easily generate water vapor in the cavity of the glass profile, and the water vapor is the insulating glass. Lifespan killer.
