Sunjoy Technology Co., Ltd. produces rock wool insulation in various forms such as boards, rolls and pipe sections. The product is manufactured from natural volcanic rock and achieves a thermal conductivity between 0.034 and 0.040 W/mK. It tolerates continuous temperatures from 650 °C up to 1 000 °C and is classified as non‑combustible. The supplier lists fire resistance, acoustic absorption and customizable densities as key performance attributes.
Rock wool is widely accepted in the building sector for its ability to meet European EN 13162 and US ASTM C1589 insulation standards. Typical board thicknesses range from 25 mm to 200 mm with densities between 30 kg/m³ and 200 kg/m³, which Sunjoy can adapt to project specifications. Standard packaging for export consists of stacked pallets, each pallet holding up to 1 000 kg of product, and the material is recyclable, reflecting its eco‑friendly origin. Compared with glass fibre, rock wool offers superior fire resistance and higher sound attenuation, making it a preferred choice for high‑rise construction.
The insulation is used in walls, roofs, floors and pipe jackets across residential, commercial and industrial projects, and is purchased by contractors, HVAC firms and equipment manufacturers. Sunjoy advertises flexible minimum order quantities and offers both FOB and CIF shipping options from Tianjin ports. Buyers are advised to request the supplier’s ISO and CE certificates and to confirm packaging details before placing an order.

Before confirming any order, verify the supplier’s ISO and CE certificates and request the latest fire‑resistance test report. Because the response rate shown is zero, consider sending a preliminary inquiry to assess communication reliability and to obtain detailed product data such as density options and packaging specifications.
Logistics for rock wool from Tianjin typically involve FOB or CIF terms; however, exact incoterms, estimated lead times and payment conditions should be clarified with Sunjoy prior to contract signing. Buyers should also confirm whether the shipment will be palletised on standard 1 000 kg pallets and whether any special handling is required for high‑temperature applications.
For quality assurance, arrange a third‑party inspection that includes thermal conductivity verification, density measurement and fire‑test validation. Request a mill test report and, if possible, a pre‑shipment sample to evaluate acoustic performance. Proper documentation, including a certificate of conformity, will streamline customs clearance and ensure the product meets project specifications.
