[0004] However, when the existing composite insulation board is used, the internal stress in the composite insulation board is large, which makes the internal structure of the composite insulation board unstable, causing the composite insulation board to crack, and having a certain impact on the service life of the composite insulation board. At the same time, when external noise passes through the composite insulation board, the composite insulation board cannot effectively reduce the noise sound waves, which will cause the noise sound waves to continue to propagate inwardly. Therefore, a new type of low internal stress composite insulation board is provided. Utility Model Content
