How to do a good job of heat preservation in rural self-built houses

There are two common roof designs for self-built houses in rural areas: flat roof and sloping roof. Although the construction of flat roofs in rural areas is relatively simple, which is conducive to the drying of crops, the heat dissipation of sloping roofs is relatively better, so the sloping roofs of rural self-built houses will be cooler in summer. In addition, insulation boards or materials can be installed between the roof and the ceiling.

The insulation board method can be used for the second floor of the self-built house, that is, the pearl sand insulation layer with a thickness of 10 cm is laid on the roof, and then a layer of cement prefabricated insulation board is laid. You can also use the soil layer insulation method, which can store 20 cm thick soil layer for greening and planting flowers and plants, which not only beautifies the harsh environment, but also has the function of heat preservation and heat insulation.

Thermal insulation coatings are mainly used on walls, which can be divided into three types: thermal insulation, thermal light reflection and radiation insulation. Choosing these suitable paints during decoration can also play a role in heat preservation, so it is also a good choice.

Extended data:

After the temperature of tile roof rises in summer, a large amount of radiant heat enters the room, which leads to the continuous rise of temperature and extremely uncomfortable working and living environment. The solar radiation absorption coefficient (normal total radiation emissivity) of aluminum foil coil is 0.07, and the radiation heat is very small. It is widely used for heat insulation of roofs and walls.

Heat energy transmission way (without heat insulation film): solar-infrared electromagnetic wave-heat energy hits the tiles to raise the temperature-tiles become heat sources to release heat energy-heat energy hits the cast-in-place roof to raise the temperature-cast-in-place roof becomes heat sources to release heat energy-indoor environment temperature continues to rise.

Heat energy transfer path (with heat insulation film): solar-infrared electromagnetic wave-heat energy hits the ceramic tile to raise the temperature-ceramic tile becomes a heat source to release heat energy-heat energy hits the aluminum foil to raise the surface temperature-aluminum foil has extremely low emissivity and releases a small amount of heat energy-and a comfortable ambient temperature is maintained indoors.
