Frederick and Vera also mingled in the crowd. They went straight to a 65 square meter public rental house without looking at the bigger one.

On the one hand, there are only four people in their family, and the two rooms of 65 square meters are enough.

On the other hand, because Vera needs to take care of her two daughters at home, she has to be a full-time housewife. She only depends on Frederick to support her family. Her financial situation is quite tense. For them, eight silver nals is also a great burden.

The appearance of public rental houses is not much different from other houses. They are all square in shape and have sharp roofs, but the details are quite different.

Before entering the gate, the couple only looked at the whitewashed wooden wall, and their eyes showed their love.

It''s not just the two of them, it''s almost everyone around.

The wooden wall looks incredibly flat, without a crack. It''s hard to believe that it''s actually made of long wooden boards.

Usually, the walls of the wooden house that two people see are more or less uneven, because it is almost impossible to ensure the smooth surface of such a long wooden board by hand.

The same is true of the edge of the board. After assembling into a wooden wall, you can always see many small cracks. If the craftsman''s skill is poor, the cracks of finger thickness are not uncommon.

Compared with the public rental house in front of them, the best wooden house they have ever seen is no different from the crooked melon and cracked dates.

Frederick participated in the construction of public rental housing. Seeing his wife''s face full of admiration, he explained in a low voice: "I heard other workers say that these boards are processed by a very powerful machine, and the processing is fast and good. A hundred carpenters can''t hold that kind of machine..."

Vera''s eyes widened and asked a series of questions: "really? What does that machine look like? How does it work? "

Frederick grinned awkwardly: "only a few wood transport workers have seen the machine several times. No one else has seen it."

Seeing that his wife was disappointed, he quickly changed the topic: "guess what the surface of the wooden wall is painted with?"

Vera turned to look at the wooden wall and replied, "isn''t it lime? It''s said that this kind of thing is added to the cement... "

"It''s not just lime," Frederick said. "If you just brush lime water, it won''t take long to fall off. There''s fish bone glue and two other kinds of seaweed glue in the lime water."

"Mr. civil servant calls it" white fish paint ". It is very hard and won''t peel off easily after being dried. You can feel it."

Willa hesitated and looked at the others: "but just now the director said that the facilities of public rental housing should not be destroyed..."

Frederick said with indifference, "I''ve touched it countless times. It''s not like there''s nothing left."

Seeing her husband''s hasty face, Vera had to nod helplessly. She carefully approached the wooden wall and quickly reached out her hand to touch the snow-white white fish paint when people didn''t pay attention.

Because she was a little nervous and moved too fast, her feeling was not very clear, but it seemed very hard and delicate.

Some of Frederick''s devotees seized her hand and turned it over: "you see, you see, there is no white mark at all. I tell you, if it is lime water, it will leave white marks..."

Seeing a trace of surprise on his wife''s face, he laughed with pride: "in fact, there is more than one layer of paint on the wooden wall, and there is a layer of black asphalt paint under the white fish paint."

"Mr. civil servant also said that the asphalt paint was invented by the Lord. After painting it on the wooden wall, it can prevent insects and corrosion. The wooden wall can be used for a longer time, eh This is called anticorrosive primer, which can effectively prolong the service life of the product. "

This kind of professional description was obviously learned by Frederick from civil servants. After he said this, his face became more and more proud. It seemed that he had become a "learned" civil servant.

Vera gave him a funny nudge: "well, well, I know the asphalt paint is very good, and the Lord has invented a great thing."

At this time, Frederick suddenly remembered something, and his tone became more excited: "dear, Mr. civil servant also said that there is a very big advantage in painting two layers of paint on wooden walls..."

At this point, he deliberately stopped, staring at Willa''s face, saw her not blinking at himself, this satisfied to say the answer: "not ventilation!"

Vera Leng for a second to react, she was extremely surprised and asked: "really?"

Frederick nodded positively: "of course it is! White fish paint and asphalt paint will completely block the gap between the boards, and there will be no leakage of wind! "

Why does "no wind" surprise Vera so much?

The reason is winter!

Just imagine, if there are big cracks and small cracks on the four walls and the roof, and there is a strong wind outside, there will be a small wind inside. In other seasons, it''s just that. In winter, it will be colder inside. Who can bear it?

I can''t stand it, I have to!

Most civilians have to suffer in winter. Although almost every household has fireplaces, it is impossible to light them every day in order to save fuel.Then why not collect a room full of firewood and burn it every day in winter?

This is a good question, but if anyone asks any civilian like this, he will spit in his face: who doesn''t want to do this? How long does it take to collect a room full of firewood?

Some of the firewood collected has to be used to make a fire for cooking. The firewood for heating at night can only be saved. In ordinary days, just to support the family, you have to work all day long. When you get home, you''re already half dead. It''s not easy to accumulate firewood in a small room, do you know?

Therefore, in the long cold winter, most of the time, civilians have to stay at home shivering, the whole family huddled together for warmth.

In the tidal islands, winter is more severe.

This place is located in the marine environment, and the dimension is not low. The cold current from the south of the polar region can reach the tidal islands in a smooth way. Unlike the Dushan Kingdom, there are tall mountains in the north to block the cold wave.

Therefore, after winter, there will be continuous snowstorms in the tidal islands, when the temperature will directly soar to more than minus ten degrees, or even more than minus two or three degrees.

Therefore, in the tidal islands, many people are frozen to death every winter.

"No ventilation" means that the heat loss rate is slower, and it is more conducive to keeping warm. There will be no temperature outside and no temperature inside.

The wood with the same weight can be used for a longer time.

Only this point, greatly increased the civilians "alive" through the cold winter''s probability!

For most civilians, a wooden house without air leakage in winter is enough to make them feel very happy.

Vera also has such a "dream", in her memory, there is no winter, she was not cold.

But today, this dream has suddenly come true!

Looking at his wife''s happy face, Frederick felt more and more happy.

Recalling what he saw and heard at work, he said: "not only that, Mr. civil servant also said that the paint layer on the external wall should not be worried about falling off within five years..."

"Five years later, even if it falls off, the white fish paint on the outer layer will fall off, and the asphalt paint on the inner layer will never fall off, but the wall is not very good-looking..."

"In addition, if it falls off, you can buy white fish paint by yourself and mend it in time. You can buy it in the shops in Hongshi Town, and the price is not expensive..."

"The paint on the interior wall can last for at least 10 years..."

Vera couldn''t help stroking the wooden wall and said with admiration: "this paint layer Er It''s a long life... "

The number of "five years" doesn''t sound too long, but don''t forget that the paint layer on the exterior wall is exposed directly. It has been exposed to wind, rain, frost, snow and cold all the year round. The environment is so bad that the aging rate is very fast. Five years has been quite a long time.

There are similar exterior wall paints in this world, but they are all juice extracted directly from tree bark, completely natural, without any chemical preparation.

This kind of paint has low output, high price and short service life. It starts to fall off in two years at most. Where can civilians afford it?

At this time, Frederick saw that the others had entered the public rental housing, and urged Willa: "let''s hurry up, the others have entered..."
