Vertical fire curtains are a popular choice for commercial and industrial projects, such as shopping centers and office buildings. They are particularly useful in areas where maintaining large open spaces for access is necessary. These curtains are typically installed into ceilings and deploy vertically, making them ideal for floor-by-floor protection in multi-level buildings with large open areas like atriums, staircases, or escalators.
One of the key advantages of vertical fire curtains is their ability to remain hidden from view until deployment. This feature makes them an excellent option for designs that prioritize esthetics or need to conserve usable space. The DSI-C3HR Fire Protective Smoke Curtain is an example of an advanced vertical fire curtain system. It incorporates the latest electronic technology and is gravity fail-safe, making it one of the most advanced yet cost-effective systems available.
Horizontal Fire Curtains
Horizontal fire curtains are specifically designed to bisect atriums over two stories, effectively compartmentalizing smoke. They are particularly well-suited for multi-story buildings and can replace traditional fire protection equipment such as fire shutters, non-loadbearing firewalls, and fire-rated ceilings. This allows for the creation of modern, open multi-story ceiling voids while maintaining excellent fire compartmentation.
It’s worth noting that horizontal fire curtains are subject to unique regulations. ISO 21524 is the only product standard used in the UK with third-party certification from a Notified Body that specifically covers horizontal fire curtains. This certification ensures the reliability and effectiveness of these intricate systems in fire safety applications.
Concertina Fire Curtains
Concertina fire curtains are multi-sided vertical curtains that deploy from ceilings. They are ideal for shielding areas such as escalators and staircases, offering a versatile solution for open-plan building designs. One of the key advantages of concertina curtains is that they do not require side guides on corners, allowing for greater flexibility in architectural planning.
These curtains can also be used to create a reservoir for smoke on higher floors of atriums and other large spaces, enhancing overall fire safety. The DH60 concertina smoke curtain, for example, is third-party certified to EN12101, a certification achieved by only a handful of manufacturers.
Key Features of Modern Fire Curtains
Modern fire curtains have revolutionized building design, offering advanced protection and enabling complex structures to be safer. These innovative systems incorporate several key features that enhance their effectiveness in fire safety strategies.
Automatic Deployment
One of the most crucial features of modern fire curtains is their automatic deployment system. These curtains are designed to work in tandem with other fire protection systems, creating barriers where partitions are limited or absent. When a fire alarm is triggered, the system sends a signal to the fire curtain, causing it to drop from the ceiling. This automatic response prevents fire and smoke from spreading throughout the building, effectively compartmentalizing the affected area.
The mechanism behind this deployment is both robust and precise. Advanced engineering ensures that the curtain will function as intended when needed. To enhance reliability, a gravity fail-safe release mechanism is incorporated. This feature allows the curtain to descend even if the motorized control fails for any reason, ensuring protection in all scenarios.
Smoke Sealing Capabilities
Modern fire curtains excel in their ability to seal off areas from smoke infiltration. The SmokeShield® Fabric Smoke and Fire curtain, for example, boasts a UL1784 smoke and air infiltration listing. This certification demonstrates its effectiveness in preventing smoke spread, which is crucial for maintaining tenable conditions and allowing people time to use escape routes.
These curtains utilize patented technologies, such as GuideLock™, to positively seal the curtain within its guide channels. This feature ensures that smoke is cut off immediately after connected fire systems detect its presence, enhancing the overall safety of the building.
Fire Resistance Ratings
Fire resistance ratings are a critical aspect of modern fire curtains. These ratings indicate the amount of time a curtain can withstand standard fire exposure. The classifications are typically expressed in minutes, denoting the product’s performance under stipulated test conditions.
There are three main fire classifications:
- E (Integrity rating): Measures the curtain’s ability to prevent flames from passing through to the unexposed side.
- EW (Integrity and radiation rating): Assesses both integrity and the curtain’s ability to limit heat radiation.
- EI (Integrity and insulation rating): Considered the highest classification, it evaluates integrity and the curtain’s capacity to resist heat conduction.
Modern fire curtains often achieve high ratings in these classifications. For instance, some curtains offer a UL10D three-hour fire protection rating, demonstrating their ability to withstand intense fire conditions for extended periods.
