The effect of exterior wall insulation board on buildings: 1. It can reduce the interference to residents. During decoration, when the building uses external insulation for renovation and construction, the internal insulation layer is easily damaged. External insulation can prevent the damage to the insulation layer during decoration. . 2. Its heat preservation and thermal insulation effect is better than that of internal insulation. Since the external wall insulation board material is attached to the outside of the wall, external insulation can reduce the construction cost, increase the use area of the house, and achieve higher economic benefits. 3. The use of exterior wall insulation boards can help eliminate or weaken the impact of thermal bridges produced around the junction of interior and exterior walls, exterior wall ring beams, structural columns, frame beams, and the junction of top parapet and roof panels. 4. Due to the strong heat storage capacity, the main structure is on the indoor side. It is beneficial to the thermal stability of the room, can prevent large temperature differences in the room temperature, and improve the moisture content of the wall. 5. The thermal insulation material of the exterior wall insulation board has a protective effect on the main structure, because the insulation layer is placed outside the building envelope. Outdoor climate conditions cause large temperature changes inside the wall, which occur in the outer insulation layer, buffering the stress caused by structural deformation due to temperature changes, preventing large temperature changes in the main internal structure, and effectively improving the durability of the main structure. , the life of the building is extended.
