Reward Wall Systems’ NoricF4 Custom Metal ICF Frames have received fire ratings of 1.5 hours to 3 hours and they have been evaluated to be in compliance with the prescriptive requirements of the Department of Defense Minimum Antiterrorism Standards for Buildings for blast/force protection.
The NoricF4 is structurally integrated to the
cast-in-place ICF concrete wall with an embedded flange around the entire
perimeter of door and window openings. The NoricF4 has been shown to satisfy
the Unified Facilities Criteria 4-010-01 for both door and window frames and
door and window mullions.
The UFC Antiterrorism Standard requires building
components to adopt and adhere to common criteria and minimum construction
standards to mitigate antiterrorism vulnerabilities and terrorist threats.
“There is an increase of government buildings and
educational facilities using insulating concrete forms to build structures,
with an added importance on safety. It’s important that Reward provides products
that meet the stringent requirements for fire ratings and blast protection,” said
P.E., vice president of Engineering and Technical
Services with Reward.
The allowable levels of protection and standoff
distance are summarized in various span tables. A doorframe meets the standard
at a maximum size of 96 inches wide and 156 inches high. A window frame meets
the standard at maximum width of 72 inches and a height of 156 inches. Door and
window mullions openings meet the requirements at a maximum opening size of 72
inches wide and 156 inches high. Additionally, fixed window frames with
integral window stops provide the necessary glazing bite for wet glazed (i.e.
silicone glazed) windows.
The company designed and created the NoricF4 custom
metal frames for doors and windows to further enhance the building envelope
required by commercial ICF construction.
