"GB/T 30807-2025 Thermal insulation products for buildings, long-term water-absorption determination by immersion method" stipulates the method of measuring long-term water-absorption of building thermal insulation products by immersion method. This standard provides a unified technical basis for evaluating the performance of thermal insulation products under long-term water absorption conditions. It is suitable for the production, testing and engineering application of building thermal insulation materials. It is of great significance to ensure the thermal insulation effect and durability of thermal insulation products and optimize the energy-saving design of buildings.
