The team responsible for on-site construction must formulate a careful external wall insulation construction process plan and process requirements. Within one week before the external wall insulation construction, the construction team technical person in charge must conduct on-site construction personnel training in professional construction and safety construction. Party A provides a detailed construction technology delivery plan to enable workers to master the comprehensive technical requirements and ensure that construction is carried out in strict accordance with the rules and regulations during the construction process.

Polystyrene board or extruded board and other auxiliary insulation materials must meet the design requirements of building structure drawings and meet the current building energy conservation standards; any unit or individual cannot change the external wall insulation system practices or reduce energy-saving design standards without authorization. If it is necessary to change the design requirements for external wall insulation, the original design unit must issue the change procedures and pass the quality supervision organization for approval before organizing the construction according to the approved change design documents.

The person in charge of material management must strictly control the insulation materials of the exterior walls of various types of entry. Products used for exterior wall insulation must use the specified energy-saving technology products that meet the policy requirements. The materials used in the external thermal insulation project must have the manufacturer's product qualification certificate and performance, the test report and seal, and the specifications, varieties and performance of various materials comply with the design specifications and relevant regulations. After the materials enter the site, they should be sampled and re-inspected according to the construction construction specifications. It is strictly forbidden to use materials that do not meet the requirements in the project.

Before the construction, it is required to do the inspection and acceptance of the related parts such as the door and window frame. The size and position of each window must meet the design requirements and quality requirements. During the construction, the joints of the external wall insulation system must be closed. The corners and the yin and yang angles should be partially strengthened, and the deformation prevention treatment should be done at the same time. When the temperature is above 15 °C and the relative humidity of the air is less than 80%, it is most suitable for the construction of external wall insulation.
