Chapter 1583

Qin Shiou thought who was coming at first, but there was no warning at sea and no visitors on land. Later, he saw the tiger and leopard shouting at their work clothes. He realized that the little guy also had to change into a suit.

He explained that it was for work. The tiger and leopard bit one of his trouser legs and had to change into that bulletproof vest anyway.

Qin Shiou is so angry. The bulletproof vests are heavy and not very ventilated. I don't understand why the two little guys like to wear them so much. He's not a smelly person. Who did the two little guys learn so smelly from?

He had no choice but to take out his dog's bulletproof vest and change it for them.

After changing, the two little guys were happy, and then lingered with Qin Shiou, as if showing off their clothes of the same color.

George and Vivian were teased. They took out their mobile phones and took pictures with tigers and leopards. Lala Wang also cooperated very well. They were full of good feelings for the camera.

Qin Shiou beckoned that it was time for everyone to start work.

George instructed the teenagers to mix detergent with warm water and wipe the tiles of the outer wall from the door to both sides.

Wind and rain, the original milky white tiles have turned into a dark yellow or turquoise because they are covered with moss. You can wipe off the moss, but you can't wipe off the changing colors.

The villa is full of the vicissitudes of the times. George sighed: "this house is at least half a century old. My father's cottage in the countryside is such a construction style. Time flies."

The whole house is built of wood. In some places, the wood has decayed. Qin Shiou needs to replace it, or use a sawdust gun to fill it with sawdust. Finally, it needs to be blocked with glue and painted with a layer of paint. It is very complex.

For this kind of old house, it costs a lot of money to repair. The key is to waste time. For the rich, it's better to build a new one.

Qin Shiou is used to living here and feels no need to change his house. Moreover, the villa needs to be repaired only at the corners. On the whole, it is still very good. For example, the solid wood stairs in the house are particularly strong. After decades of use, there is no creaking sound when stepping on them, which is as stable as a rock.

Canadian houses, especially rural villas, are mainly made of wood. Unlike the domestic use of concrete and bricks and tiles, there are many local wood, and the cost of using wood to build houses is also low.

For example, in farewell Town, the trees on the island belong to the government, but if anyone wants to build a house, he can buy a piece of wood on the ground at a very low price.

In this way, even if the new house is built, it still needs maintenance because it is still wood, and the maintenance cost is not low. We have to spend about 2% of the money to repair it every year.

The work that the teenagers have to do is the simplest and non dangerous one. They wipe the floor, wipe the windows and doors, weed and so on. The main work still depends on Qin Shiou and the fishermen.

Shack introduced to Qin Shiou: "the most important thing to repair the house is the roof. It's rainy and snowy on the island, and there are often strong winds landing, so the damage to the roof is the greatest. Later, we'll go up and have a look at the aging of the roof. There were snow disasters in the first two years, which is estimated to have caused damage. "

After setting up the ladder, several people tied their safety belts and went to the roof of the villa.

In the first year, several warehouses in Daqin fishing ground collapsed due to wind and snow. It was repaired by Sark and sea monsters. The villa was OK. The materials used were more exquisite, and professional anti-corrosion was made, which made it more resistant to rain and snow.

On the roof, the villa roof is made of layers of wood. Some have broken several layers. Although some look complete, they will become fragments when they touch them. They are aging.

There should be no problem with the roof of this villa, otherwise it is easy to cause more damage to the house. For example, once the rain leaks, it will obviously corrode the walls, because the walls of the villa are also wood, so it is not as simple as mildew or even rot.

If the roof insulation is not good, the air conditioner in the house will be turned on in winter, and the temperature can not be raised. Even if the air conditioner is turned on 24 hours a day, it is useless.

In Canada, the roofs of wooden houses need to be repaired every five years. This kind of repair is an overhaul, and many things need to be replaced. There are few people in Canada. Except for the downtown, most people live in small villas. It costs about four or five thousand Canadian dollars to change once, and the average person's monthly salary is gone.

In addition, the roof has to be replaced every 25 years, so the price is more expensive, not tens of thousands of Canadian dollars.

Qin Shiou discussed shack and other humanitarians: "do you want to have an overhaul and replace it with modern common glazed tiles?"

Shack shook his head and said, "don't change, boss. The glazed tiles are beautiful, but they are too heavy, which will cause a great burden on the walls of the house. Moreover, it is windy and snowy on the island. Coupled with the pressure of glazed tiles, the burden on the house will be greater, so it is good to use wooden boards. "

Mr. Qin was particular about people. At that time, hemlock was used for roof timber.

Tieshan is the most elegant and widely used tree species in the North American market. Its strength is slightly lower than that of yellow pine. It is more suitable for anti-corrosion treatment. After pressure anti-corrosion treatment, it is beautiful and strong, which can be comparable to the natural and durable North American red cedar.

Hemlock wood is very suitable for roof because it has great stability, small coefficient of thermal expansion and contraction, and anti tanning. It is common sense to know that almost all wood will turn black after long-term sun exposure, but hemlock can still maintain the color when it is newly sawn after perennial sun exposure. It is very beautiful to make a roof.

These iron fir trees have been treated and have a layer of transparent paint on the surface, which is a mixture of anti-corrosion paint and reinforcing paint, which can not only enhance the anti-corrosion performance of wood, but also increase its strength.

This is also one of the advantages of hemlock. They have excellent adhesion and can accept various surface coatings.

There are several floors on the roof. After Qin Shiou repaired it with iron fir, he added a layer of carbonized wood.

Now the roof of the country villa is made of wood, and generally does not use hemlock wood, but carbonized wood.

Carbonized wood is made by homogeneous carbonization of wood at high temperature. It does not need to use chemical agents. Its ability comes from itself, so it has a more stable role of anti-corrosion and resistance to external forces.

Moreover, the carbonized wood has a dark brown color on the surface, as if it can absorb sunlight. It is very beautiful.

Carbonized wood has low moisture content, not easy to absorb water, stable material, no deformation, good heat insulation performance, simple construction, convenient brushing, no special smell, anti-corrosion, anti moth, anti deformation and cracking. It is simply an excellent choice for external wood.

In addition, it also has the advantage of light weight, because it is carbonized, completely degreased without grease overflow, less mass, and less pressure on the walls and wooden beams of the house.
