Closed Cell Polyisocyanurate Foam Core: Closed cell polyisocyanurate foam technology provides additional insulation value with lightweight and low water absorption characteristics.
Inorganic Coated Glass Facers: (With no cellulose) Provide improved resistance to mold growth, as well as a smooth surface that performs well with self-adhering systems, and efficient adhesive application in adhered single ply systems.
High R-Value (2.9 R): Has more than two times the R-value of wood fiber and more than four times the R-value of gypsum boards.
