Due to the widespread use of external insulation and integrated panels for building exterior walls, the installation of this material has become an important part of the exterior wall construction process. In order to improve installation and usage efficiency, and enhance the functional efficiency of materials, strict requirements have been put forward for the installation and construction of materials. Under normal circumstances, the insulation and decorative panels are securely and safely installed. This type of use can make panels and walls more comfortable, promote the integration of materials and walls, and also contribute to the decorative effect of materials, making the appearance smoother and more beautiful.

Installation requirements: Firstly, the wall surface should undergo strict foundation treatment before installation, including wall leveling, punching, installation of suspension components, application of adhesive materials, etc., in preparation for overall board installation. Secondly, when the temperature is above 5 degrees Celsius, the windy weather should be below 5 degrees Celsius to ensure that the adhesive material can function well. During the construction period, attention should be paid to rain and dust prevention. Finally, the joint should be sealed without holes.

As a new type of insulation material, insulation decorative panels are gradually entering our lives. As an external wall insulation material, waterproof performance has become an important basis for testing its quality. So, are insulation and decorative panels rainproof? The waterproof performance of insulation decorative panels is mainly judged from aspects such as water absorption, corrosion resistance, and impact resistance. The thermal insulation decorative plate is made of polyurethane foam plastic with low thermal conductivity. Its molecular structure has poor water absorption and does not absorb water.

Rainwater may contain a large amount of corrosive substances because the surface of insulation decorative panels is polymerized, so even if rainwater impacts its surface, it will not be corroded. Insulated decorative integrated panels have excellent impact resistance. Even if it is affected by heavy rainfall, it will not fall off or collapse. It is not difficult to see from the above three points that due to its non absorption, corrosion resistance, and impact resistance, its waterproof performance is beyond doubt.

The key of exterior wall insulation material is that the covering layer has the characteristics of non cracking, waterproof, impact resistance and aging resistance. External wall insulation materials have low thermal conductivity, good insulation effect, low water absorption, high strength, corrosion resistance, and good dimensional stability. The system lifespan can exceed 25 years. Spraying polyurethane rigid foam external wall insulation material is the external wall high-pressure insulation equipment. Materials A and B are the insulation layer, polymer dry mortar is the covering layer, and glass fiber mesh is the reinforcement layer spray and foam.
