What wall is suitable for rural self-built houses to keep warm so as not to be cold in winter? How to operate?

Thank you for inviting me. Now it has entered 65438+February, and the northern region has entered the early winter season, and the weather has gradually turned cold. In some areas, the temperature during the day is now MINUS 10 degrees, while in other areas, freezing weather has appeared at night.

In this cold season, it is very important to keep warm if you want to live comfortably and not be attacked by cold weather. Nowadays, in the rural areas in the north, firewood, straw and coal are generally used for heating. For some old houses, sometimes we burn a lot of materials, but the insulation inside is poor and it will feel very cold. So when building a new house, everyone will take some measures to keep warm. One is to reduce the use of heating materials, and the other is to be more environmentally friendly.

At present, there are generally 37 walls and 50 walls in rural self-built houses in northern China, which are thick enough to resist the cold weather in northern China. Masonry requires bricklayers to fill mortar joints first, so as to reduce the gaps between bricks and avoid the invasion of cool wind in winter.

At present, the building materials used in the north are mainly red bricks, and the thermal insulation materials are mostly foamed polystyrene board, which is called polystyrene foam board. This material has good effects of heat preservation, sound insulation and blocking cold air. If the building with the wall of Sanqi is adopted, a layer of benzene board with a thickness of about 5 ~ 10 cm can be pasted on the external wall of the building after the building is completed, which can effectively increase the indoor temperature by more than 3 ~ 5 degrees.

If a building with 50 walls is used, there are two ways to use benzene board. One method is to add benzene board with a thickness of 1 layer 10 cm between two 24 walls, or add benzene board between a 24-wall and a 37-wall. The other is outer layer pasting.

The effect of adding benzene board to wall 50 is better than that of adding benzene board to wall 37, which saves burning raw materials in winter, but the corresponding construction cost will also increase. In addition, when choosing benzene board, we must pay attention to its material and choose benzene board with good flame retardant effect produced by regular manufacturers.

With the decrease of red brick building materials in rural areas, a new building material with very good thermal insulation effect has emerged, that is, sea capacity module. Hairong module is a benzene plate frame building, supported by reinforced concrete, with excellent thermal insulation performance. But it has a disadvantage that it is not resistant to mice, and it is easy to be drilled by mice, and cold air invades the room. Therefore, it is best to do some protective measures at the bottom around the house to avoid the invasion of rats.
