Looking for a 1h+ fire rated wall covering material, moisture proof like cement board #green
I am looking for a ceiling/wall material to safely cover XPS in a 'wet area' such as a bathroom. Is there a material with the properties of type X or C drywall having the durability of cement board combined? In particular I need fire rating 1h+ and moisture / mold resistance as with cement boards. Can you recommend various materials I can use to cover XPS with above characteristics so I can install it in a 'wet' area indoors as wall panel or ceiling panel?
