Description
When used in combination with the proprietary U370 firewall design — the SANCTUARY Two-Hour Firewall — Greenfiber FRM Insulation meets the requirements for a two-hour fire rating, making it ideal for townhome and multifamily construction. Rated by Underwriters Laboratory, the U370 firewall works together with Greenfiber FRM Insulation to achieve defect-free installation. Two opposing and offset studded walls create an 8" cavity into which FRM is spray-applied, filling the entire cavity and reducing air infiltration in the assembly.
