What is the main problem of waterproofing the balcony?

As far as balcony windows are concerned, the first thing is to pay attention to the quality of the broken bridge aluminum window, the sealing should be good, and the second is not to make a mistake about the inside and outside of the waterproof frame. After the balcony window is installed, there will be gaps in the places where the window frame is in contact with the wall, but this gap must be within the allowable range, because these places need to be covered with special glue to prevent each contact surface from leaving no gaps; Of course, if the gap is too large, the window size is too small, and how to fill the gap with glue, it feels tight at that time, but after a period of time, the glue will shrink after a long period of sun exposure, and then there will be a gap again, which is also an important factor causing the leakage of the balcony. Similarly, the glass on the balcony window and the window frame are not fully sealed, in addition to the sealing strip to be pasted in these places, they also need to be glued, and the glass glue used here is generally high, and the adhesion to the glass is higher.

There is also the waterproof problem of sealing the balcony window and the quality of the glue used will also have a certain relationship, if the glue is not adhered enough, there will be gaps exposed after a period of use, and the water outside will still leak in, so the choice of this glue can not be sloppy, when choosing the glue, we must be careful and choose special glass glue. Install the sealed balcony window, the top is a point, if it rains, the rain is flowing down from top to bottom, so when installing the top of the sealed balcony window, it is necessary to extend the top into the inside of the beam above the balcony, and the internal length of the beam should reach more than 7 cm, and the top should have a certain angle, so that in the rainy day or the water on the beam surface flows down from the top, it will not flow back into the sealed balcony room.
