A 3-hour fire protective smoke curtain for rated barrier walls.
— APPLICATION
Openings in smoke barrier walls, openings in fire partition walls, elevator lobby interface, fire rating glass applications, and openings in corridors. Considered a "smoke barrier" in the IBC, the SD240GS® deploys to the floor in side guides (rails) recessed into the wall cavity or flush with the face of drywall. The headbox is bespoke, in two types — single roller or multi-roller — depending on the width of the opening.
