The production, testing, and application of glass wool boards generally adhere to a series of national standards and industry specifications, which govern the material across three key dimensions: product performance, safety and environmental protection, and construction application.
Regarding product performance, a fundamental standard is "Glass Wool Products for Building Thermal Insulation" (e.g., GB/T 13350). This standard specifies parameters such as density, thermal conductivity, combustion performance, and dimensional tolerances to ensure the material meets uniform technical requirements for thermal insulation. Additionally, fire safety performance must typically comply with the "Classification for Burning Behavior of Building Materials and Products" (GB 8624), with a preference for meeting the Class A1 standard for non-combustible materials.
At the construction and application stage, compliance with regulations concerning building energy efficiency and fire safety design-such as the "Standard for Energy Efficiency Design of Buildings" and the "Code for Fire Protection Design of Buildings"-is required. These codes dictate how glass wool boards are applied in walls, roofs, suspended ceilings, and equipment insulation systems. Requirements cover aspects such as thickness selection, structural layering, and fire isolation measures to ensure the safety and effectiveness of the installed system.
Standards regarding environmental protection and occupational health are also becoming increasingly comprehensive, featuring clear requirements for dust control in fiber products, limits on formaldehyde emissions, and occupational health protections for construction personnel. Furthermore, certain regions or projects may adopt stricter green building assessment standards to enhance the material's environmental profile and sustainability performance.
