Fire Rated Roller Door

The door is designed to protect escape routes from the effects of fire, thus enabling building occupants to reach final exits. The fire curtain will protect the building contents by limiting the spread of fire and smoke while still allowing the passage of people or goods from one compartment to another. Fire shutters are manufactured in a similar way to conventional shutters, and can be fitted for manual closing or electrically operated for controlled descent.
