SECTION 074219 – FIRE RESISTIVE-CORE METAL WALL PANELS
PART 1 - GENERAL
1.1 SUMMARY
A. Section Includes:
1. Fire resistive mineral wool-core metal wall panels.
1.2 PERFORMANCE REQUIREMENTS
A. Structural Performance: Metal wall panel assemblies shall withstand the effects the following
loads and stresses within limits and under conditions indicated, based on testing according to
ASTM E 330:
1. Wind Loads: Determine loads based on the following minimum design wind pressures:
a. Uniform pressure of 30 lbf/sq. ft., acting inward or outward.
2. Deflection Limits: Metal wall panel assemblies shall withstand wind loads with
horizontal deflections no greater than 1/240 of the span.
B. Air Infiltration: Air infiltration shall not exceed .04 cfm per square foot of wall area when
tested per ASTM E 283 at a static pressure of 12.0 psf.
C. Static Water Penetration: There shall be no uncontrolled water penetration through the panel
joints at a static pressure of 20.0 psf when tested per ASTM E 331.
D. Surface Burning Characteristics: The insulated core shall have been tested in accordance with
ASTM E 84 for surface burning characteristics. The core shall have a maximum flame spread
of zero and a maximum smoke developed rating of zero.
E. Fire Resistance: Metal wall panel assemblies shall meet the requirements of fire endurance
rating for nonbearing wall in accordance with UL 263 Fire Endurance Tests, Design No. U050
and ASTM E 119 Fire Test of Building Construction and Materials.
1. The finished panel in a seven inch thickness shall meet the requirements of a two hour
fire endurance rating.
2. Through-Penetrations: The two hour fire rated wall panel shall meet the requirements of
composite panel penetration conditions listed by UL and in accordance with ASTM E
814 Fire Tests of Through-Penetration Fire Stops. Maximum diameter of opening is 6
and 7/8”. Openings can be located on or off panel unit joints.
