The balcony window leaks when it rains. What is the reason and how to solve it?

1, different types of windows have different water leakage.

There are two main types of windows: casement windows and sliding windows. Recently, a frameless window is popular for balcony sealing.

The casement window has better sealing performance. After closing the window, the window is closed more tightly, so the casement window is the least prone to water leakage. In order to ensure the flexibility and convenience of push and pull, the gap seal of push and pull window is not good, and the slide rail is even worse. Therefore, if the sliding window encounters heavy rain, it may leak.

The sealing performance of frameless windows is worse. There is no sealing measure between the glasses of frameless windows, otherwise it will be very inconvenient to open them. Therefore, frameless windows can't stand the wind and rain, or they will leak if they are not good.

2, window frame material differences

Common window materials are plastic steel window, aluminum alloy and broken bridge aluminum. The strength of aluminum alloy is low, and the aluminum alloy window may be deformed to some extent after a long time, so its rain-proof performance is not good.

Is there a gap between the glass and the window frame?

In some families, there is a gap between the glass and the window frame. It may be that after a long time, the glass glue on it will fall off and there will be a certain gap. In this case, it is enough to reapply weather-resistant glass glue.

4. Is there an inclined water slope?

Generally, the countertop outside the window is inclined, and the outside is inclined downward. If there is rain on the countertop, it will flow down faster, and if the countertop outside the window is flat, there may be a lot of water.

5. Check the drain hole of the window.

Many window frames under windows have several drainage holes. If there is water in the window frame, it can be drained well. But if there is no drainage hole or the drainage hole is blocked, more and more water will accumulate inside, so that it will overflow the window frame and then overflow into the room.

6. The waterproof layer is waterproof.

If there are still problems after various inspections, it may be the waterproof problem of the wall, which will be more troublesome. If necessary, you need to knock on the outer wall and repaint it for waterproofing.
