1. Be sure to make the balcony according to the size, that is to say, some rooms are not necessarily sized, and the height difference between the left and right sides of the balcony may be 2 cm. If it is not sealed according to the actual size, there will be a big gap on one side.

2, the balcony must be tight, there can be no gaps. In addition to the above, there are sewer pipes, which must be sealed after drilling holes in the glass, otherwise mosquitoes will enter.

3. If it's tempered glass, don't stick it too tightly with the glass, and it will break in the sun.
