About Us
Industrial thermal insulation & refractory manufacturer since 1982.
Our Story
Rosetexwool Insulation Refractory Co., Ltd. has been at the forefront of industrial thermal insulation since 1982. Headquartered in Zhengzhou, Henan Province — the heart of China's refractory industry — we design, manufacture, and export a complete range of high-performance insulation materials including ceramic fiber, rock wool, calcium silicate, microporous boards, and nano aerogel products.
Over four decades, our solutions have been deployed in more than 60 countries across petrochemical plants, power stations, steel mills, cement kilns, and environmental protection facilities. We combine advanced production equipment, rigorous quality control, and deep application expertise to help customers reduce energy loss, improve process safety, and extend equipment life.
