Johns Manville manufactures customized glass fiber nonwoven facers to provide superior weather resistance for exterior gypsum sheathing.

Mineral-coated, microfiber alloyed and uncoated products feature tailor-made air permeability for controlled slurry penetration.  The smooth surface is designed to easily accept coatings or to act as the primary surface finish.  JM nonwoven facers effectively protect the gypsum core, product edges and other sensitive parts.
