1. Advantages of metal-carved insulation board: The exterior wall board has moisture-proof and waterproof performance. The closed porosity of rigid polyurethane is more than 90%. It is a water-repellent material and will not leak due to the thermal conductivity of moisture absorption. With excellent heat insulation performance, under the same insulation requirements, the thickness of the outer structure of the building can be reduced, thereby increasing the indoor use area.

2. Wide application of thermal insulation board: The thermal insulation board is mainly used for exterior wall decoration and energy-saving renovation of various buildings such as stadiums, libraries, schools and hospitals; the main functions are architectural decoration, heat preservation and energy saving, thermal insulation and sound insulation. And waterproof and mildewproof.

The exterior wall panels have been widely used in many industries in China, and have made great contributions to China's construction industry, in line with China's sustainable development path, and made more contributions to people.

Compared with ordinary plates, thermal insulation decorative boards have many advantages, not only good thermal insulation performance, but also beautiful appearance, which is more favored by consumers. Although the performance of the product itself is very good, if the following changes still require type testing, the main inspections are:

1. When the materials, main raw materials or construction and production processes of the thermal insulation decorative panel system change.

2. When new products are put into production or product type identification.

3. When the factory inspection result of the thermal insulation decorative board is significantly different from the previous type inspection result.

4. When the production is suspended for more than half a year, the production will resume.

5. When the national quality supervision agency proposes the type inspection requirements.
