FRM Insulation - SANCTUARY® Two-Hour Firewall Assembly

When used in combination with our 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. Designed to meet today’s stringent energy codes, FRM is spray-applied into an 8″ cavity between offset studded walls, completely filling gaps, reducing unintended airflow and helping achieve 3 ACH50. The result: builders meet stringent code and airtightness standards while delivering better sound control, indoor air quality and long-term comfort.
