ROXUL SAFE™ 55 & 65 are medium-density insulation products designed for exterior and interior non-load-bearing, steel-faced firewall applications where a fire resistance of at least one hour is required. 

ROXUL SAFE™ 65 holds a fire-resistance rating of one hour, while ROXUL SAFE™ 55 holds a fire-resistance rating of two hours—both from the interior side.
