Anonymous users2024-01-24In general, in residential buildings, there is a unified channel for smoke exhaust and exhaust in the bathroom and kitchen, and the developer has reserved holes in the built house. These holes are in the walls of the pre-built smoke exhaust ducts. If you want to change it, then you have to start a new hole, and this is not up to the developer.
If it is an old-fashioned house, it is generally not so thoughtful, there is no unified smoke exhaust channel, and the developer can't find it, so these holes are ignored.
Therefore, the developer is responsible for drilling the holes in the design, but the developer does not care about the holes outside the design drawings.
Yes, it is recommended to tie a stainless steel screen at the outer opening, or make a small screen window to prevent birds from entering the nest and affecting ventilation.
It's not a big problem, the one that was opened was the exhaust outlet of your own home, and the other one was a public straight row, and you might have some return air when you used that one. It's like an exhaust vent in a kitchen.
Go directly to the developer and ask for openings and compensation. As long as the developer's drawings have this exhaust outlet, but you can't see it, if you go to court, you will definitely win. Because the developer did not follow the design drawings for construction.
Generally, it is advisable to be about 15 cm away from the ceiling.
The exhaust duct has two airways, one is the main airway and the other is the bronchi. >>>More
