A method of preparing a fibrous panel including surface treating a mineral wool with a water repellent agent to provide a water-repellent surface treated mineral wool, admixing the water-repellent surface-treated mineral wool with water to provide a slurry, and dewatering and drying the slurry to provide a fibrous panel. A method of preparing a mineral wool having a surface treated with a water repellent agent including contacting a water repellent agent emulsion with a mineral wool and drying the mineral wool, and a method of preparing a water-repellent surface-treated fibrous panel including mineral wool having a surface pre-treated with a water repellent agent are also provided.

Disclosed herein are low density fiber cement articles, such as fiber cement building panels and sheets, comprised of multiple overlaying fiber cement substrate layers having small and uniform entrained air pockets and low density fillers distributed throughout. The combination of entrained air pockets and low density fillers provide a low density fiber cement matrix with physical and mechanical properties similar to comparable low density fiber cement matrix without entrained air pockets.
