ABSTRACT:
A water-resistant, fiberboard for use in making panels and tiles for building construction is disclosed. The fiberboard contains primary components which include mineral fiber, low density, nonfibrous inorganic filler and organic fiber. The fiberboard includes about 0.1-2 wt % of silicone fluid, preferably polymethylhydrogensiloxane, which improves water resistance without adversely affecting other physical properties.
