Fire Resistance

Test Results

NFPA 285 Engineering Analysis Compliance Letter

 

ItemFire Resistance Time (minutes)
2" concrete 34
Air cavity (minimum 3.5") 20
5/8" Type x gypsum 20
Total Fire Resistance 74 minutes

The above analysis indicates that a SlenderWall assembly with 5/8" Type x gypsum wallboard or equivalent containing no insulation in the cavity would easily meet a one-hour fire resistance requirement.
