1.Preparation: First of all, the wall should be cleaned and repaired to ensure that the surface of the wall is flat and firm, and there are no water leaks and other problems. If there are cracks or breakages, they should be repaired first.
2.Material selection: choose the appropriate insulation material according to the actual needs, the common ones are extruded polystyrene (XPS), polyurethane foam board, rock wool board, glass wool board, etc. When selecting, it is necessary to consider the thermal conductivity, fire performance, compressive strength and other indicators of the material, and refer to the relevant standards for selection.
3.Installation of insulation materials: In accordance with the requirements of the specification and construction drawings, the insulation materials are cut, pasted, fixed and other operations to ensure that there are no gaps and cracks between the insulation layer and the wall. Pay attention to ensure that the joints between the insulation materials are treated to ensure that the connection is firm and the sealing is good.
4.Waterproof layer construction: The waterproof layer is installed on the insulation layer, and different waterproof materials such as coatings and membranes can be used. The waterproof layer should be complete and firm, and the connection with the surrounding components should be sealed.
5.Finishing layer construction: According to the needs, select the appropriate finishing materials for construction. Common finishing materials are stone, paint, tile, plaster, etc. Ensure that the finishing material is well bonded to the insulation, and that it is beautiful and durable.
When carrying out exterior wall insulation construction, special attention needs to be paid to the following issues:
1.Construction environment: The construction of insulation materials should be carried out under suitable temperature and humidity conditions to avoid problems such as material deformation and cracking.
2.Building structure: Before construction, it is necessary to understand the structural characteristics and load requirements of the building, and pay attention not to damage the original building structure in the process of setting the insulation layer.
3.Construction quality control: construction is carried out in strict accordance with the specifications and design requirements to ensure that the thickness and quality of the insulation layer meet the requirements, and to ensure the insulation effect and safety performance.
4.High-rise building construction: For the external wall insulation construction of high-rise buildings, special attention should be paid to construction safety and protective measures to prevent accidents such as falls.
In short, exterior wall insulation construction needs to follow relevant specifications and requirements to ensure construction quality and safety. In practice, it is recommended to ask a professional designer or construction unit to provide guidance and supervision.
