FireWall 1HR & 2HR

FireWall® is a non-combustible, rigid stone wool insulation board that is designed for use as a component in Roxul non-combustible steel faced fire wall assemblies where a one or two hour fire rating is required.

Applications:
This product is designed for exterior and interior non-load bearing steel faced fire wall applications where a fire resistance of at least one hour is required.

Two product variations:
FireWall® 1HR holds a fire resistance rating of one hour, from the interior side, as specified in ULC Design No. W605 and UL Design No. U654. In addition, it holds a fire resistance rating of one hour from both sides, as specified in ULC Design No. W610 and UL Design No. U658.

FireWall® 2HR holds a fire resistance rating of two hours, from the interior side, as specified in ULC Design No. W606 and UL Design No. U655. In addition, it holds a fire resistance rating of two hours from both sides, as specified in ULC Design No. W611 and UL Design No. U659.
