External wall insulation refers to a kind of insulation material used for wall construction. It is mainly composed of polymer mortar, glass fiber mesh cloth, flame-retardant molded polystyrene foam board or extruded board and other materials. Thermal insulation, waterproofing, and decorative functions are the preferred materials for the external insulation of modern buildings. Today Xiaobian is talking about the advantages and construction requirements of exterior insulation. External wall insulation advantages: 1. The effect is good Because the insulation material is placed on the outside of the building's exterior wall, it can basically eliminate the “cold and hot bridge†influences of various parts of the building. The thermal insulation performance of the light and new-type high-efficiency heat-insulating materials can be fully utilized. Compared with the external wall inner heat-insulation and sandwich heat-insulation wall materials, under the condition of using the same heat-insulating materials, the thickness of the heat-insulating materials needs to be smaller to achieve a higher energy-saving effect. 2. Improve indoor environment The external insulation of the external wall of the building improves the thermal insulation performance of the wall, reduces the conduction loss of the indoor thermal energy, and increases the thermal stability of the interior. In addition, to a certain extent, it has prevented the soaking of peripheral walls such as wind, frost, rain, and snow, improving the moisture-proof performance of the wall, and avoiding phenomena such as mildew, condensation, and cold penetration in the interior. This creates a comfortable indoor living environment. In addition, the insulation material is applied to the outside of the wall to avoid the pollution of the indoor environment caused by the volatile harmful substances in the insulation material. 3. Protected The insulation layer placed on the outside of the building greatly reduces the influence of natural temperature, humidity, and ultraviolet rays on the main structure. In particular, due to the influence of temperature on the structure, the thermal expansion and contraction of the periphery of the building may cause cracks in the non-structural components of the building. The use of external thermal insulation technology in the external wall can reduce the stress generated within the structure. 4. Wide range The external insulation of the external walls of the building is not only suitable for buildings that require heating in winter in the north, but also for air-conditioned buildings that need to be insulated in summer in the south. That is, it is suitable for the thermal insulation of the masonry concrete masonry wall, and also for the insulation of the shear wall structure concrete wall. Not only applies to new construction, but also applies to energy-saving renovation of existing buildings. External wall insulation construction requirements: 1. The construction and acceptance of the exterior wall and exterior doors are completed, and the base surface meets the requirements of relevant regulations. 2. The ambient temperature for the normal construction of external insulation systems is 5°C~35°C. 3, the construction site should be to achieve road access, water, electricity. 4. Construction erection tools and scaffolding shall meet the construction requirements and be safe and reliable. 5. The mobile distribution box and tap water pipes used in construction shall be configured according to the construction requirements. 6. Vertical and horizontal transport facilities for distribution materials are required to comply with relevant safety regulations. 7. The distance between the high-voltage electric wires and the construction site in the construction operating environment shall comply with relevant regulations and have corresponding protective facilities. 8. Remove all obstructions on the wall surface to be insulated. 9, the wind when the insulation board is not more than 5 levels. 10. To ensure construction quality, the construction surface should avoid direct exposure for a long time, and it should not be constructed in rainy days. 11, construction tools: slotting machine, wallpaper knife, screwdriver, scissors, ink fountain, brown brush, electric mixer, plastic, mixing barrel, impact drill, hammer, trowel, pallets, 2m on the ruler.
