My windows are two-layered. When winter comes, there will be a lot of moisture on the windows. Over time, the middle of the two-layered windows will become very dirty. Can anyone help me find a solution~! !

Let me help you find a solution. Below is an article I wrote, I hope it can help you.

Do you know the three main reasons why water drips from windows? The solution is quite simple, you might as well give it a try

"What's the matter with water dripping from the windows? Can installing laminated windows solve the problem?"

With the arrival of winter, the weather is getting colder. , this type of consultation suddenly increased. My answer is: Installing laminated windows can alleviate the water leakage in the windows to a great extent, but it cannot ensure that there will be no water leakage at all. Because there are three major causes of water dripping from windows, we cannot completely solve them.

1. Caused by cold weather

In Changchun in the North, the weather is the coldest in late autumn, winter and early spring of the year, and it is during this season that the phenomenon of dripping water appears. When the outdoor temperature is below 0 degrees Celsius, the temperature difference between indoor and outdoor increases, and when the moist air (water vapor) in the room encounters the cold glass windows, condensation will occur, which is what physics calls condensation, and the gas condenses into liquid. The more liquid accumulates, it will flow down the window and onto the windowsill or even the ground. The colder the weather, the colder the glass windows will be, and the more serious the condensation will be. On the contrary, in the warm weather of late spring, midsummer and early autumn, who has seen water dripping from the windows?

2. Caused by water vapor in the room

The humid air in the room is also called water vapor. We know that no one lives in an empty house, no matter how cold the weather is, there will be no water dripping from the windows. As long as people live in a house, water vapor will be produced. On a winter morning, the outside of a private car is covered with frost, but the glass inside is very clean. But when people get in, the windows are covered with condensation. Of course, the water vapor in the same house is also different in size. In some homes, there is so much moisture that black hair grows on the walls near the windows, but in other homes, this does not happen. This is related to the size of the house, the number of people and the living habits of the residents. If the house area is large and the population is small, the water vapor will be relatively small. On the contrary, the water vapor will be large. In addition, the owner of the house is accustomed to cooking food, raising flowers and fish, and being diligent in doing laundry and mopping the floor... These will produce a large amount of water vapor, which will condense into water flow, pool on the ground, and even penetrate under the floor. After wiping it clean every day, it would drip again, and it would not be wiped clean again and again, which annoyed the owner of the room.

I remember a customer suddenly called me a few days ago and said why there was water on the windowsill and on the floor in the kitchen? The glazed windows installed in December last year have not had this problem. Is there something wrong with the glazed windows? ——It’s simply impossible. "Did the water consumption suddenly increase and the water vapor increase?" I asked. He suddenly realized that a large group of out-of-town friends came to the house and cooked a lot of dishes... and it was really like that.

3. Caused by problems with the windows themselves

Currently, there are some common problems with windows throughout the city and even in the three northeastern provinces and three northern regions.

1. The windows have fewer glass layers

The Ministry of Housing and Urban-Rural Development’s building exterior window standards require three-pane windows in northeastern regions and four-pane windows in cold regions. So we see that buildings after 2014 all have triple-glazed windows. It is said that a newly opened building in a community in Jingyue, Changchun actually has four windows. However, buildings before 2014 only had two-layer glass windows. In summer, it is as hot as a fire in front of the two-pane window; in winter, it is freezing cold in front of the window. With such a thin window, can water vapor prevent condensation and dripping water in winter?

I remember that in the early years, my home had single-layer wooden windows. In winter, the glass was covered with thick white frost. When the sun came out, the center of the glass melted, and water flowed all over the window sill. At night it freezes again, and sometimes the curtains are so frozen that they can't be opened. Later, the unit divided us into a house with two plastic-steel windows, which was much warmer. The ice and frost had disappeared, leaving only water flowing. Now the two-pane windows have been installed with laminated windows. In the coldest weather, there is still some breath on the windows, but there is no water dripping anymore. It can be seen how important it is to keep the room warm, cold and water-proof, and multi-layer glass in the windows.

2. The distance between the windows is narrow

According to the prevailing manufacturing standards for plastic steel windows in Changchun, the distance between the two windows should be 4+12A+4 or 4+9A+4. ("4" is the thickness of the glass, "12A" or "9A" is the spacing of the insulating glass in millimeters, the same below), the triple glass window is 4+12A+4+12A+4 or 4+9A+4+9A+ 4. Unfortunately, the spacing of window glass in many households is not up to standard. The warmth of the windows relies on the sealed cavity formed by the spacing of the insulating glass. If the spacing is not enough, the indoor heat can be directly conducted out, so how can we keep warm and prevent cold? So water dripping from the windows is inevitable.

3. Poor sealing of windows

In 90% of residential households in Changchun, the windows have poor sealing and air leakage. Air leakage between the frame and the wall, aging and missing sealing strips between the glass and the window frame, air leakage, air leakage at the beading, air leakage when the fan is opened and closed at an angle... In order to prevent wind, people have thought of many ways, such as replacing the rubber strips and pasting them. Plastic sheets, sticky tape, etc. cannot solve the fundamental problem and greatly reduce the quality of life. These air leaks not only lower the room temperature, but also cause a large amount of water vapor to condense directly into water and flow down, which is the main cause of water dripping from windows.

Although installing laminated windows cannot solve the problem of cold weather or the problem of high water vapor in the customer's home, it can solve the problem of the number of layers of windows, upgrading two-pane windows to three-pane windows; it can solve the problem of poor air leakage and sealing in windows. and other problems, raising the room temperature can greatly alleviate the water leakage situation. Three years of experience in adding laminated windows has proven that the problem of water dripping from the windows of some customers has been completely solved, some families have solved the problem by 80 or 90%, and some have solved it by 60 or 70%. We will continue to explore and work hard to bring comfortable life to all people who need it.
