We offer glass fiber nonwovens 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.
Evalith® 89 series mats are unique, dense, nonwoven glass fiber mats. The glass fibers are oriented in a random pattern and bonded together with an acrylic resin binder. The density and composition of the bonded glass fibers form a product with smooth surface qualities, moisture and penetration resistance.
This product is a glass nonwoven with defined fiber diameter and fiber length. The fibers are longitudinally laid down randomly oriented and binder bonded. This type is finished with a mineral coating providing good sealing against gypsum slurry. Low calorific values are typical for this product series.
