The air we normally breathe actually contains water vapor.
Take the winter window as an example, when the hot air in the room hits the cold glass, it will be cooled, and the water vapor in the air will turn into water droplets, which will be attached
to the glass window by condensation phenomenon.
According to research, a house of 30m2 produces 0.25L of water in a day and night.
The glass and windowsill always dews and drips water, which penetrates into the edge seam of the windowsill and makes the bottom wall of the windowsill moldy. When it flows to the wall, it makes the wallpaper moldy and falls off. Condensation is not only difficult for cleaning work, but also causes the growth of mold, which is very harmful to human health.
Vacuum insulating glass is an effective measure to anti- condensation. Because of its unique vacuum structure, it has a high thermal insulation performance, which makes it difficult for the indoor heat to radiate out, so the surface temperature is higher than the dew point, so it is not easy to produce condensation.
