Abstract:
1. A method of forming a coated glass mat comprising: conveying a glass mat substrate having non-woven glass fibers into contact with an applicator roll; applying a coating comprising latex binder and inorganic pigment to the glass mat substrate having non-woven glass fibers with a surface of the applicator roll to form the coated glass mat; said coating being only partially permeated into said substrate while also imparting a tensile strength to the coated glass mat which on average in a machine direction is at least 1.33 times greater than the tensile strength of the glass mat substrate without the coating, said coated glass mat having a porosity in a range of from 1.3 CFM to 5.0 CFM per square foot.
