Why HVAC Wrap IS NOT Code Compliant
for Most Applications
Ceramic Fire Wrap Does Not Offer 2-Hour
Fire Inside Tested Protection* **
Many manufacturers only tell half the story:
Ceramic fire wrap for non-grease applications is only tested for 2-hour fire outside conditions.If project specifications call for ISO 6944 testing standards, industry veterans may assume a 2-hour Outside (Type A) wrap is compliant.† Not so – insist on full compliance!
Why Doesn’t Wrap Comply With Certain Code Testing Requirements?
ISO 6944 requires testing for all 4 conditions:
Horizontal and Vertical for Both Outside (Type A) and Inside (Type B)
Are you being told that a product meets all ISO 6944 test requirements? Wrap is not tested to 2-Hour Fire Inside (Type B) conditions.This could leave your projects non-code compliant and vulnerable.
How Could This Happen?
After years of use, and with ceramic fire wrap viewed as the industry standard – how can this be true? The answer: HVAC products are generally regulated by mechanical codes rather than building codes. However, you need to look in both code sources. As an alternate for drywall enclosures, fire-rated HVAC systems must comply with both, yet fire wrap does not fully comply with all code testing requirements. European countries typically do not accept Outside (Type A) tested solutions for full ISO 6944 compliance, because they do not test for 2-Hr fire Inside (Type B) conditions. Testing must be in place for both exposures.
What’s My Risk?
Code Officials across the US should expect full ISO 6944 compliance. If you specify or install fire wrap in buildings that has not been tested in accordance with Code requirements, you may be at risk for violating the Code. That could create significant exposure for your business and your profession.
