Import Glass Wool — Buy in wholesale FOB from Supplier in China

Glass wool from Saint Firstman Group is a thermal and acoustic insulation material composed of fine glass fibres formed from silicate glass. The product is supplied in rolls, batts, boards, and loose-fill formats, with densities spanning 10 to 100 kg per cubic metre and thermal conductivity between 0.034 and 0.040 W per metre Kelvin. These properties make it effective for reducing heat transfer in building envelopes and industrial applications. The material’s fibrous structure traps air, providing both insulation and sound absorption, while its non-combustible nature meets Grade A fire resistance standards typical for mineral wool products. Typical applications include walls, roofs, floors, and HVAC systems in residential, commercial, and industrial construction projects. Glass wool is also used in industrial settings such as pipe insulation and acoustic panels, where its lightweight and flexible nature simplifies installation. International buyers often source it in bulk for large-scale projects, benefiting from its cost-effective thermal performance and ease of handling.

The material is manufactured from silicate glass fibres, with average fibre diameters ranging from 4.0 to 6.0 micrometres, a standard measurement for glass wool products. It is hydrophobic, with a typical moisture resistance of over 98.5%, ensuring long-term performance in damp environments. The product’s highest usage temperature is 400 degrees Celsius, a standard threshold for glass wool in industrial and construction applications. Its heat absorption coefficient is approximately 1.03 using the reverberation method, a typical value for this category. Standard roll dimensions range from 600 to 20000 mm in length and 600 to 1200 mm in width, with thicknesses between 25 and 200 mm, allowing customisation for different insulation requirements.

Glass wool is primarily sourced by contractors, builders, and distributors for infrastructure and commercial building projects, where energy efficiency and fire safety are critical. The product is traded internationally in standardised formats, making it a key material for global insulation markets. Buyers should confirm packaging, lead times, and compliance with local building codes, as these can vary by region. Saint Firstman Group’s offering aligns with typical industry specifications, ensuring compatibility with standard installation practices.

Saint Firstman Group is based in Nanjing, Jiangsu Province, China, with its registered address at No.16, Suojin Fifth Village, Xuanwu District. The company operates as an imported-tier supplier, indicating it sources or distributes materials for international trade. Its profile does not list a response rate or average response time, so buyers should expect to follow up directly for inquiries. The supplier specialises in insulation materials, with glass wool as a key product line, catering to construction and industrial sectors.

The company’s focus on insulation aligns with its role as a material supplier for large-scale projects. While its trust tier is classified as harbor, suggesting a baseline level of verification, buyers should confirm details such as certifications, production capacity, and quality control measures directly with the supplier. Saint Firstman Group’s location in Nanjing, a major industrial hub in China, positions it well for logistics and export operations.
