Taishi Rock Wool Co., Ltd. is a Chinese manufacturer and exporter of A1 non-combustible rock wool (stone wool) and glass wool insulation, supplying importers, insulation distributors, sandwich-panel producers and cold-storage contractors across Indonesia.
Rock Wool Insulation Supplier for Indonesia
Indonesian distributors and cold-storage contractors buy our rock wool boards, strips and pipe sections in 40HQ and LCL shipments through Tanjung Priok and Tanjung Perak. We regularly quote for cold rooms, sandwich panels, and factory roof and duct insulation.
We work with buyers in Jakarta, Surabaya, Medan, Bandung, Semarang and Denpasar — as the factory, not a trading company, so you deal directly with the producer.
Why Indonesian buyers source from Taishi
- Factory-direct pricing — 800,000 tonnes of annual capacity across seven production bases, with 10 basalt-fibre and stone wool production lines.
- Fire performance where it matters — rock wool is A1 non-combustible (EN 13501-1), the natural choice for high-rise facades, cold rooms and industrial plants.
- Specification flexibility — densities from 40 to 200 kg/m³, thickness 30–200 mm, custom sizes and facings.
- Samples before commitment — free samples with batch test reports before you place a container order.
- Export paperwork done properly — CO, packing list, invoice, and container or LCL shipping.
