SAFTI FIRST’s 2-Hour Fire Rated Curtain Wall Passes Rigorous Dynamic Tests Fire as Prescribed by CDC

CDC (Curtain Wall Design and Consulting) is a  leading independent firm providing a wide range of building envelope design,  engineering, and consulting services to design professionals nationwide.

SAN FRANCISCO, CA (October  30, 2012) – SAFTI FIRST, leading USA-manufacturer of  fire rated glass and framing systems, is pleased to announce that in addition  to meeting ASTM E-119/NFPA 251/UL263 with hose stream for up to 2 hours, the SAFTIfire CW Framing System meets or exceeds  the performance specifications of other leading U.S. manufacturers of either  fire rated or non-fire rated curtain wall systems by successfully passing the  following tests:

  • Air  Infiltration, ASTM E 283-04, Rate of Air Leakage Through Exterior Windows,  Curtain Walls and Doors.
  • Static  Pressure Water Resistance, ASTM E 331-00, Standard Test Method for Metal  Curtain Walls and Doors by Uniform Static Air Pressure Difference.
  • Dynamic  Water Pressure Resistance, AAMA 501.1-05, Standard Test Method for Metal  Curtain Walls and Doors by Uniform Dynamic Pressure.
  • Structural  Performance, ASTM E 330-2, Structural Performance of Exterior Windows, Curtain  Walls, and Doors by Uniform Static Air Pressure Difference.
  • Seismic  Movement, AAMA 501.4-09, Recommended Static Test Method for Evaluating Curtain  Wall and Storefront Systems Subjects to Seismic and Wind Induced Interstory  Drifts.
  • Thermal  Cycling and Condensation Evaluation.
  • Interstory  Vertical Displacement Tests.

“The  SAFTIfire CW Framing System is unique  because it performs as a fire barrier while still being part of the building’s  exterior skin.  It provides protection in  the event of a fire while enhancing the building’s overall aesthetics and  performance,” says Tim Nass, VP of National Sales at SAFTI FIRST.  “Our recent testing  based on the CDC prescribed project performance requirements provided empirical  data that demonstrates the SAFTIfire CW Framing System’s ability to prevent air and water infiltration under  non-static conditions, such as wind load or moving live loads that meets or  exceeds the performance of curtain wall systems offered by other leading U.S.  manufacturers.”

“The  dynamic testing performed on our mock up was designed to mimic real world  installations,” adds Tim.  “Our system’s  documented performance ensures that architects have a proven option for clear,  unobstructed views when faced with property line requirements or other  scenarios where the threat of fire comes from the outside.”

Meeting  property line requirements was exactly the case for The Kensington, a 27-story,  488,000 square foot, mixed-use, residential building in Boston, MA.  The west-facing elevation had to meet ASTM  E-119/NFPA 251/UL263 for 60 minutes, so SAFTI FIRST supplied SuperLite II-XL 60 insulated with Solarban 70XL in  SAFTIfire CW Framing.  CDC was hired to make sure that the building  was air and water tight.  They were  present during the dynamic testing performed by ATI (Architectural Testing,  Inc.), an independent testing laboratory, where the mock-up of the system  provided by SAFTI FIRST passed all  required testing.

The  aluminum covers used in the SAFTIfire CW  Framing System mimics the appearance of an aluminum pressure wall, making it  easy to match the non-rated exterior glazing systems seamlessly.  The ability to incorporate Solarban 70XL to  the fire resistive system also contributed to meeting an average U-value not  more than 0.40 and a solar heat gain coefficient no greater than 0.25 as required  in the specifications.  Since the SAFTIfire CW Framing system is thermally  broken, it is a natural selection for exterior fire resistive applications in  places that experience extreme weather like the Northeast.
