MgO Board for Fire-Rated Ductwork
Board components for HVAC and smoke-exhaust duct systems that require a defined, project-specific assembly.
Sulfycor non-woven magnesium oxysulfate boards can be evaluated for duct enclosure or board-duct systems. Board thickness, joints, supports, access panels, seals and the required complete-system rating must be reviewed together.
