Smoke Guard’s M4000 fire-rated curtain does not require corner support posts and is the ideal solution for vertically deploying perimeter curtain applications. This type of fire curtain can shield staircases or escalators from smoke and flames, or provide a reservoir for smoke on the upper floors of an atrium or other open space. This perimeter curtain can be an effective complement to existing mechanical smoke and fire containment systems or additional fire curtains.
