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.

Multilayer facer

A system for forming a facer includes a hydroformer that receives a first fluid and a second fluid. A first fluid line is configured to deliver the first fluid to a first inlet pipe and a second fluid line configured to deliver the second fluid to a second inlet pipe. The first fluid line includes a first fiber source that stores a first type of fibers and a first thick stock pump that pumps the first type of fibers to the first inlet pipe. The second fluid line includes a second fiber source that stores a second type of fibers and a second thick stock pump that pumps the second fluid to the second inlet pipe. The first fluid and second fluid are simultaneously poured or delivered onto a porous belt or surface to form the facer.
