4. Exterior wall system
The main structure of the house is mainly reinforced concrete wall, with high-density insulation board set outside, air troposphere set aside, and open dry hanging external wall set. The middle flowing air layer can take away the condensed water on the insulation board, effectively ensure the long-term drying of the insulation material, and maintain its insulation performance continuously and effectively. The air layer and dry hanging external wall play a good role in sunshade and heat insulation in summer, and also effectively prevent the invasion of rain water.
5. Exterior window system
The window is made of aluminum alloy with bridge cut-off and heat insulation, which effectively blocks the cold and hot outside. The joint space between the window frame and the window opening is also designed with heat resistance to isolate the heat conduction of these subtle places. With double-layer hollow glass and low-E coating, it can resist heat both inside and outside. In winter, the indoor heat can not go out, nor can the cold come in. In summer, the outdoor heat can not come in, nor can the indoor cold go out.
6. External sunshade system
Aluminum alloy external sun blind is installed outside the window, with the maximum sun shading rate of 80%. It can not only block direct radiation, but also block diffuse radiation, so as to reduce the indoor cooling load and achieve the purpose of energy saving.
7. Roof ground system
The roof is provided with a thick insulation layer, and the parapet part is also tightly wrapped, and the insulation layer is extended to the ground below the frozen soil layer, forming a closed insulation system to block the energy loss in all directions.
8. Noise isolation and sound insulation system
The exterior wall system, the exterior window system and the floor are all provided with sound insulation construction measures to effectively block the noise from the outside and between floors and provide a quiet indoor environment.
9. Drainage noise treatment system
The system adopts the post drainage sanitary equipment to discharge the sewage and waste water into the main pipe in the pipe well in this layer, so as to effectively solve the impact of drainage noise.
10. Dust collection and drainage system
Change the traditional garbage disposal method, unify the central dust collection, make the garbage not stay in the room, unify the central classification, and do not give bacteria breeding conditions.
