Fire rated roller shutter doors are a key component to any building design. They are UL tested and approved to close during a fire event to prevent flames from spreading to areas that need additional protection. They can be installed in any opening, including doors and windows.
These shutters can be fabricated in a variety of sizes to fit any window or door opening, and are available with optional smoke control. They are also a great option for elevators to help prevent them from becoming chimneys, which can contribute to the spread of fire.
Understanding Fire Rated Roller Shutter Doors: Features and Benefits
A fire shutter curtain consists of interlocked laths of cold-rolled Galvalume / Galvanised / Stainless Steel that are securely held using alternate profile ends to eliminate lateral movement and provide a stable, high-integrity curtain. These shutters can resist fire for up to 4 hours. Regular inspection & maintenance of these shutters are essential for safety & reliability.
During a fire, the insulated rolling fire door protects egress points and wall openings with an insulated core that keeps temperatures steady. It can be triggered by a fire alarm, smoke or heat detector or a 165-degree melting fuse link and can be programmed to automatically close.
These fire rated counter shutters are custom-designed to match opening specifications and use compact guides, brackets and hoods that reduce coil, header and sill size for a smooth profile and tight fit. They are also UL labeled up to 3 hours for fire resistance and can be painted any color.
