Certifications & project submittals
The manufacturer literature identifies FM approval and GREENGUARD Gold for Aerocell Class 0. The download above is a Loneflex technical summary, not an approval certificate. Request the current manufacturer-issued certificate or test report and confirm its scope against your exact product, thickness and project requirements.
ASTM and BS references identify test methods or classifications; they are not separate product approvals. Class 0 does not identify a firestop system. Typical manufacturer test data should be checked against the project specification.
