There is generally no door at the balcony entrance, but at most one entrance cover (door cover), and then the finished sliding door is customized. All door covers and pass covers shall be horizontal and vertical. Check with a vertical measuring ruler. If the balcony pass is not horizontal and vertical, there will be gaps after installing the sliding door; When laying floor tiles, play a horizontal line on the wall. Check the floor tiles according to the horizontal line, and don't use the bricklayer's level.
If the sliding door is not square (which is rare), it may be that the two sides of the door cover are not vertical, which is the responsibility of the carpenter; It is the bricklayer's responsibility that the tiles are not laid properly.
Note: All door covers and pass covers should be horizontal and vertical. Check with a vertical measuring ruler.
When laying floor tiles, play a horizontal line on the wall. Check the floor tiles according to the horizontal line, and don't use the bricklayer's level (the error will be great).
Remedial measures for defects:
By carrying the door, keep the sliding rail of the sliding door high and low, and ensure that the gaps on both sides are tight. But the consequence is that the two doors are not vertical.
Curtains must be installed at the entrance and balcony. Indoor because your living room area is small, install a light color department, the pattern should not be too big, it seems that the place has become bigger. A bamboo curtain is installed on the balcony, which is ventilated but not light-tight, which can let the air circulate and block the sun. You can use it as you like.
