摘要： A glass facer for a constructions board includes a first non-woven layer of coarse fibers and a second non-woven layer of coarse fibers and microfibers. The glass facer also includes a binder that simultaneously binds or adheres the coarse fibers of the first non-woven layer together, the coarse fibers and the microfibers of the second non-woven layer together, and the first non-woven layer to the second non-woven layer. The first non-woven layer has a porosity and air permeability that enables the first non-woven layer to absorb a material of the construction board when the glass facer is positioned atop the construction board during manufacture of the construction board. The second non-woven layer is configured to block the material of the construction board from passing through the glass facer to an exterior surface of the second non-woven layer so that the material is not externally visible.
