1, because the doors and windows of self-built houses are generally large, the heat emitted by these places accounts for about 35% of the whole building. In addition, the energy consumption of the ground and roof also needs to be considered. So if you do thermal insulation around the house, it is estimated that the total energy consumption can be reduced by about 15%, and it is estimated that it will not have an immediate and obvious effect as you said. If the windows and doors are double glazed, you should be able to feel the warmth obviously.
2 polystyrene board is not the cheapest thermal insulation material, but it has the highest cost performance. If you stick tiles outside, you only need to use metal mesh or reinforced glass fiber mesh. There is no need to consider too much tile safety for the first floor building. However, special tile bonding mortar should be used for tile bonding.
3 The insulation of untreated clay brick walls is limited to new buildings with a building age of less than 3 years. Also consider whether there is oil pollution or something that is not conducive to adhesion on the building wall. Your new house is absolutely fine.
There are many insulation modes. You can't make the sandwich wall yourself. Benzene board system is your best choice. 5 cm thick benzene board insulation in civil building area. If the project team contracts, the material belt in Tangshan area is about 60 square meters. You can refer to it yourself. It's not a big problem to do it yourself, and it doesn't require much technology.

Thermal insulation is still necessary, recommended. Rural areas in many areas are also undergoing thermal insulation renovation, and self-energy-saving renovation is subsidized by the state.
Application of thermal insulation materials
1, apply thermal insulation material.
Coating thermal insulation material is also called thermal insulation slurry. The paste product produced in the factory is called Gou insulating coatings; The dry material produced into powder in the factory is called insulating powder; Thermal insulation mortar is made by mixing thermal insulation material and binder on site and adding water.
This material has the advantages of convenient construction, economy and good thermal insulation effect, and can also solve the problem of dew condensation on the inner surface of the external wall in winter. The development prospect of this material is very broad.
2. Expanded polystyrene foam plastic board
This material is abbreviated as EPS. ? EPS board external wall insulation is a new building material coated with polymer mortar, which is composed of special polymer mortar, EPS board and glass fiber grid cloth. Suitable for all kinds of external wall insulation of new and old houses.
This material has the advantages of light weight, good thermal insulation, convenient cutting and construction, and has the decoration of the ocean.
3. External tile insulation board
Although the external insulation board on the external surface of the external wall has good insulation effect, it is difficult and uneconomical to construct, so it is not widely used at present.
This kind of insulation board has two types: self-hanging and rear hanging. Mainly used for external insulation of new and existing external walls. It can also be used for interior wall insulation, roof overflow protection, and good floor and awning insulation.
Therefore, in rural self-built houses, we should not only choose the correct thermal insulation materials, but also use them correctly, and apply them to the structure of buildings to play the role of thermal insulation materials, so that houses have better thermal insulation performance.
