The secret to fighting against French villas

Previously French villas built in Hanoi are not only cool in the summer, warm in winter but never wet when it is sunny.

Dr. Nguyen Ngoc Chau, Vietnam Academy of Science and Technology has a large room in a villa built by the French. In the summer of 2006, he renovated the house, moving from a one-story house to two floors. To do this, he had to lower the base from 75cm to 5cm, and raise the ceiling higher.

To prevent sores, design the floor with good heat transfer materials.(Illustration).

When landing, Dr. Chau found that the house was designed with a background of golden sand (about 45cm thick) and coal slag (about 25cm). Therefore, despite breaking the old background, he still decided to make a new background as well as above: Digging into the negative core 50 cm, then pouring a layer of 30cm yellow sand, continuing to be a layer of 20cm slag, on the same slice with normal tiles.

The results were very satisfactory, in the days when the doctor's house was still dry while his sister's house right next door (with the wall) was very wet. Even the common wall was on the side of Mr. Chau's house, and on the side of her house she was soggy.

To combat the humidity, there may be other solutions but according to Dr. Chau, it is possible to apply a fairly simple solution that anyone can do: It is the design of the floor with good heat transfer materials, not must be as good as a few insulation articles.

Because the wetness of the floor is caused by the difference in temperature between the substrate and the substrate, the moisture in the air condenses on the floor surface. Like when you put a cup of ice cream or a glass of cold water on the table, after a few minutes you will see the outside of the cup condensing into water, not because the water from the cup is absorbed or from the floor soaked up as many people mistakenly thought.
