Fire-Rated Machine-Made Rock Wool Sandwich Panel Passes Class A Test as Anhui Jiufa Adds Magnesium Oxysulfide Option for Cold Storage

2026 05/09

HUAI NAN, China – A cold storage facility in Shanghai recently replaced its old insulation with Anhui Jiufa’s machine-made magnesium oxysulfide sandwich panel and cut energy loss by nearly one third. The panel resists moisture where rock wool cannot go.

Anhui Jiufa New Material Technology Co., Ltd. produces machine-made rock wool sandwich panels, machine-made magnesium oxysulfide sandwich panels, machine-made hollow glass magnesium sandwich panels, handmade rock wool sandwich panels, handmade glass magnesium rock wool sandwich panels, and mechanically made sandwich panels.

The machine-made rock wool version achieves Class A fire resistance, making it suitable for cleanrooms and industrial workshops. The magnesium oxysulfide panel offers moisture-proof performance for cold storage and prefabricated buildings. Handmade options allow thicker cores for specialized projects such as soundproof studios or high-impact zones.

All panels are manufactured inside an industrial park in Liugang Town, Shou County. The company serves construction contractors and prefabricated building manufacturers across domestic and export markets.
