The overall insulation decorative panel for exterior walls is a typical prefabricated component. It is a new type of external wall insulation material that is prefabricated in the factory, formed and transported to the site, and then installed in the form of "building blocks". Especially suitable for the exterior walls of prefabricated buildings. Compared with other external wall insulation materials, the effect is better. As for the phenomenon of thin plaster peeling off, it is not due to the insulation performance of rock wool. This is a systems engineering project, and there are many factors that cannot be attributed to the rock wool itself. The concept of green consumption and green development has been further strengthened. Rock wool composite board can save resources, protect the environment, reduce pollution, and provide people with a healthy, suitable, and efficient space for use.

The overall insulation system of the exterior wall panel should be able to adapt to the normal deformation of the base layer. Under long-term self weight, wind load, and outdoor climate change conditions, there should be no cracks, hollowing, detachment, or other damages. In rare earthquakes, it should not detach from the bottom. External wall insulation integrated board is a thermal insulation structural system that uses cement-based double-layer composite board as the external template, pours concrete inside, and is coated with anti cracking mortar protective layer. The double-sided rock wool composite insulation template is firmly connected to the concrete through connectors.

A large number of applications in the field of architecture: According to statistics, energy consumption accounts for over 60% of building energy consumption, and wall energy consumption exceeds the average level. This determines that polyurethane composite panel external wall insulation systems will become the main body of external wall insulation systems. This utility model is lightweight, has good insulation effect, is easy to construct, has good fire resistance, and has the same service life as buildings. Avoiding common quality issues such as hollowing, cracking, detachment, and fire in external wall insulation technology, it is in line with the implementation of building energy-saving technology.

Production and processing personnel should ensure that the surface of the external wall insulation board is flat, clean, dry, and firm. There shall be no peeling, hollowing or other phenomena that affect the quality of the board. Use a 2m ruler to check the flatness and verticality of the rock wool composite board. The maximum gap between the exterior wall base and the ruler shall not exceed 5mm. When stacking building materials and placing construction equipment on the floor, the load-bearing capacity of the floor structure should be checked and examined. If the load-bearing requirements cannot be met, necessary temporary reinforcement measures should be taken. The distance between the rock wool composite board and the construction wall should not be too far, generally within 20m.
