To improve the quality of building exterior wall insulation projects, we can start from the following aspects!
1. The team responsible for on-site construction must develop a careful plan for the exterior wall insulation construction process and process requirements. Within one week before the construction of exterior wall insulation, the technical person in charge of the construction team must conduct comprehensive and professional construction and safety construction training for on-site construction personnel and provide Party A with a detailed construction technology briefing plan so that workers can have a comprehensive understanding of the construction technology. technical requirements, and ensure that construction is carried out in strict accordance with specifications and procedures during the construction process.
2. Polystyrene board or extruded board and other auxiliary insulation materials must comply with the requirements of the building The design requirements of the structural drawings must comply with the current building energy-saving standards; no unit or individual can change the exterior wall insulation system practices or lower the energy-saving design standards without authorization. If it is really necessary to change the design requirements of the exterior wall insulation, the change must be issued by the original design unit Only after the formalities have been reviewed and passed by the quality supervision agency can the construction be organized in accordance with the approved change design documents.
3. The person in charge of material management must strictly control all types of exterior wall insulation materials entering the site . All exterior wall insulation systems and products such as insulation panels used for exterior wall insulation must use energy-saving technology products that meet policy requirements stipulated by Beijing. The materials used in exterior wall insulation projects must have the manufacturer’s product qualification certificate and performance test report and be stamped. The specifications, varieties and performance of various materials must comply with the design specifications and relevant regulations. After the materials arrive at the site, they must be sampled and re-inspected in accordance with the building construction regulations. The use of materials that do not meet the regulations in the project is strictly prohibited.
4. The on-site construction team and on-site workers must hold certificates and undergo pre-job training, and strictly enforce safe production Awareness ensures safe production.
5. Exterior wall insulation panels must meet fire performance requirements. Achieve the flame retardant level according to the design requirements of the building drawings, and use fire isolation tape products at appropriate locations.
6. The exterior wall insulation board should be installed flat on the wall and the horizontal error should be controlled within the specified range.
7. Pay attention to the influence of weather factors during construction. In principle, when the humidity is relatively low, Construction is allowed under the conditions. If the air humidity is too high, it is required to apply interface agent or similar products on the base layer.
8. When constructing polystyrene board thin plastered exterior wall insulation projects, it is best to It will be carried out after the base wall has received the acceptance report from the Quality Supervision Bureau.
9. During construction, the joints of the exterior wall insulation system must be sealed . Parts such as corners and yin and yang corners should be strengthened locally and treated to prevent deformation.
10. Before construction, it is required that door and window frames and other related parts have been installed and passed the quality inspection For the department’s acceptance work, the size and position of each window must meet the design requirements and quality requirements.
11. The construction of exterior wall insulation is most suitable when the temperature of the working environment is above 15℃ , it is most suitable if the relative air humidity is less than 80%. Humidity problems will have less impact during the construction of Beijing exterior wall insulation projects.

12. The construction of polystyrene board exterior wall insulation should be based on “safety first, prevention Fire prevention safety is the top priority. Fire prevention measures must be taken to nip hidden dangers in the bud.
In short, the construction of building exterior wall insulation project is a complex system project, and its materials , the level of construction technology is a key factor affecting the quality of the project. Every step must be taken care of, and every process must be completed with quality and quantity.
