Abstract:
According to one embodiment, a method of forming a facer includes forming a first layer of nonwoven glass fibers and positioning a second layer of reinforcement fibers atop the first layer of nonwoven glass fibers. The method also includes coating the first layer of nonwoven glass fibers and/or the second layer of reinforcement fibers with a binder composition and pressing the first layer of nonwoven glass fibers and the second layer of reinforcement fibers together between a pair of rollers. The binder composition is then dried to couple the first layer of nonwoven glass fibers and the second layer of reinforcement fibers to form the facer. The first layer of nonwoven glass fibers and/or the second layer of reinforcement fibers are free of a material coating prior to coating of the binder composition.
