Import Glass Wool — Buy in Bulk from Supplier in China

The product offered is glass wool insulation blanket supplied in rolls ranging from 2 to 20 metres in length, 1200 mm in width and 50 to 100 mm in thickness. Its bulk density is specified between 12 and 20 kg per cubic metre, and the thermal conductivity coefficient lies between 0.042 and 0.049 W/m·K. The fibre diameter is 8 µm, and the material carries an A1 non‑combustibility rating, indicating it is non‑flaming. Water absorption is limited to 0.2%, while the water repellent treatment achieves a 99% resistance rate.

Glass wool of this construction is typical of high‑temperature insulation used in industrial furnaces and building envelope applications. The temperature service range of -120 to 400°C matches standard grade glass fibre products used for both cryogenic and high‑heat environments. A sound insulation coefficient of 0.8‑1.1 dB is common for blankets of the stated thickness, providing acoustic damping alongside thermal performance. The low slag nodule content, less than 0.3%, aligns with industry expectations for clean fibre structures.

Buyers such as plant engineers, construction contractors and HVAC system integrators often specify this material for its combined thermal and acoustic properties. The supplier packs the blankets under vacuum to reduce shipping volume and protect the fibres during transit. Importers should request the full trade terms, including incoterms and payment conditions, directly from the supplier before finalising any order.
