Make U.S. Smoke & Fire your Basis of Design
UL Listed, UL Labeled, UL Certified, UL Recognized Fire protective smoke curtains (File# R26410)

Atrium Separation Case Study: The Max Plank Institute in Jupiter, FL

In this project, there is a three-floor atrium that is categorized as a two-floor atrium with a communicating space separated by a one-hour fire protective curtain.

The two-floor rule applies, which is 404.5 exception 6 that no active smoke control  is required for a two-floor atrium. Fire Protection  Engineers with the authority having jurisdiction are able to remove all active smoke extraction systems since the curtain is UL certified (see UL On-Line Certification Directory) for one hour. The curtain deploys by gravity and maintains tenable conditions for the egress corridors during the evacuation sequence.

Options:

  1. Provide an extraction system- this is not gravity fail-safe. Is four times the cost of curtain technology and increases life cycle cost.
  2. Provide a Glass Block wall- not possible since it needs to be open for the monumental stairway in non-alert times.
  3. Fire Shutter- No space in floating ceiling for this. The curtain is a housing of 12 inches for a 30-foot drop height and weighs only 10 pounds a linear foot.

Why Choose Fire Protective Smoke Curtains for Your Open Floor Plan?
  • Rated as for 1 hour, 2 hours and 3 hour smoke and fire partition, barrier and opening protective.
  • Only a 7 inch by 7 inch housing for up to a 18 feet length with a 10 feet drop height.
  • Housings of 7 inch by 11 inches for lengths longer than 19 feet.
  • Typical 60 feet length curtain housing with 40 foot drop only 8 inches by 13 inches.
  • Accordion smoke and fire barrier systems makes turns and angles without posts and rails.
  • Gravity Fail Safe Deployment.
  • Fully Integrates with Fire Alarm System with optional building management system relay per UL 864.
  • Report holder for Elevator smoke containment and elevator lobby smoke containment per ICC AC-77.
  • Utilized to Rate Corridor in lieu of fire rated glass, washing glass In lieu of horizontal accordion doors and cross corridor area separation with pass through egress.
  • Enclose monumental stairways and secondary Egress paths makes fixed glass draft curtains a thing of the past.
  • Curtains with redundant forms of egress, pass through egress, rewind switches, two stage descents, delayed descents.
  • Curtains used for stages per NFPA 80 guidelines.
  • Restricts Atrium Volume as part of an Atrium Smoke Management System per IBC 909 and IBC 404.5 exception 3.
  • Provides Atrium Separation per IBC 404.5 Exception 6 back to 2 floor rule for removal of smoke management system.
  • Horizontal Curtains to separate two floors allows architects to design more open floor plans.
It's not just what we make,
