What is the role of door and window sealing tops?
Sound insulation, waterproof, sealed, dustproof
Sound insulation: If there is a gap between the sliding doors and windows, it is easy to produce wind noise when the wind blows; the role of the top is to cushion and fill the gap, so that the sealing and sound insulation effect of the product is better.
Sealed waterproof: good tops are not easy to absorb moisture (easy to block rainwater). Like the sealing strip, the sealing strip can also prevent dust and flying insects from entering the room through doors and windows.
