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 constructed from a fiber wet-process mat and is covered with a latex-based, inorganic coating that can be used as a product component or a finished product.
