How to improve the quality of building exterior wall insulation projects

To improve the quality of building exterior wall insulation projects, we can start from the following aspects!

1. The team responsible for the on-site construction must formulate a thorough external wall insulation construction process plan and process requirements. Within one week before the external wall insulation construction, the technical leader of the construction team must conduct a thorough inspection of the on-site construction personnel. Provide training on professional construction and safe construction and provide Party A with a detailed construction technical explanation plan so that workers can master comprehensive 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 design requirements of the building composition paper and comply with the current building energy conservation standards; no unit or individual can change the external wall insulation system without authorization Or lower the energy-saving design standards. If it is really necessary to change the design requirements for exterior wall insulation, the original design unit must issue a change procedure and pass the review by the quality supervision agency before the construction can be organized in accordance with the approved change design document.

3. The person in charge of material management must strictly control all types of external 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 enter 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 to work, and undergo pre-job training, and have strict awareness of production safety to ensure safe production.

5. Exterior wall insulation panels must meet the requirements of fire protection performance, reach 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 panels should be installed flat on the wall and within the specified range of horizontal error control.

7. Pay attention to the influence of weather factors during construction. In principle, construction is allowed when the humidity is relatively low. 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 plaster exterior wall insulation projects, it is best to proceed 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 acceptance of the quality department. 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°C, and the relative humidity of the air is less than 80%. Humidity problems have less impact on the construction of exterior wall insulation projects in Beijing.

12. The construction of polystyrene board exterior wall insulation should be based on "safety first, prevention first". Fire 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. Its materials and construction technology level are key factors affecting the quality of the project. Every step must be taken care of to ensure quality and quantity. Complete every step. </p
