Polyiso Exterior Sheathing
When applied to polyiso panels and used as a substrate, Atlas WEBTECH® Coated Glass Facer (CGF) protects against moisture and improves fire resistance. CGF is a dimensionally stable, fire-resistant substrate that will not shrink or expand and is not affected by moisture.
CGF is produced using a glass-fiber wet-process mat that is covered with a latex-based, inorganic coating that can be used as a product component or a finished product.
