The 3 Hour Fire Shutter is ideal for applications where there is high risk of fire or where open areas can channel the fire out of control. The Fire Shutter closes automatically when activated to prevent the fire from spreading into the adjacent area. It is commonly used for shopping malls, fire curtain dividers, supermarket entries, warehouses, office buildings and flammable storage buildings. Fire Shutters are highly recommended where flammable materials are present.
