1. Optimize ventilation performance
When the uPVC window is down, the room can not only be ventilated naturally, but the most important thing is that the air enters the room from the window or side, and will not directly blow to the body. Especially when the temperature difference between indoor and outdoor is large, it can greatly reduce the number of people. Risk of catching a cold due to direct blowing. Especially in high-rise apartments or empty villa communities, the wind is very strong in spring and autumn, and the inverted state of the PVC windows completely makes the exchange of indoor and outdoor air smooth, comfortable and soft.
2. Improve safety
When the window is down, the window is open and ventilated. At the same time, it is very safe and anti-theft performance compared to the outer casement or inner PVC casement window. The reason is very simple-the thief can even reach into the window, but Can't open the window, let alone enter the room! Therefore, the owner can completely set the windows in the inverted state when leaving the house, which not only ensures continuous ventilation, but also does not have to worry about the gentleman's patronage.
3. Dustproof and rainproof
When the window is down, the airflow entering the room will first be blocked by the glass. The heavier dust particles in the air are less likely to "turn sharply" and are naturally blocked outside. On a rainy day, because the rain falls from above, even if it shifts into the room due to the wind direction, it will be blocked by the glass of the inverted window. Therefore, when the owner is not at home, there is no need to worry about accidental rain damaging the furniture and floors.
4. Easy to clean
Owners who live on the second floor and above and open windows from outside must have the following painful experience: the PVC window basically cannot be cleaned, the reason is simple, it opens out, even if your arm is long and flexible enough to reach out of the window, but Unfortunately, you live on the 28th floor. Is it too dangerous to stick most of your body out of the window to wipe the window? And the inverted window is completely free of this trouble, as long as the window is fully opened inward, it is easy to take care of!
