- Since 1998 Armstrong has produced more than 1 Billion square feet of ceilings with BioBlock performance. The market result:
- In five years, no claims for mold and mildew growth when installed and maintained in appropriate environmental conditions.
|
- All mineral fiber ceilings specified for high humidity spaces, with any organic content, should include the added protection
of a mold and mildew inhibitor, such as Armstrong's BioBlock.
- All 115 Armstrong mineral fiber HumiGuard Plus TM ceiling products include BioBlock to resist the growth of mold and mildew.
|
- SGS US Testing* - an independent ASTM-certified laboratory - tested Armstrong ceilings with BioBlock performance 43 times
since 1998:
- 40 tests: Ceilings with BioBlock® performance scored a perfect "no mold growth, 0%."
- 3 tests: Ceilings with BioBlock performance scored "traces" of mold growth, that is, less than 10% of the surface was affected.
- In all 43 tests, ceilings with BioBlock performed consistently. All samples tested had 0-10% growth.**
- The rating scale had no impact on the 43 test results. The G-21 rating scale requires that for a 0 or 1 to be awarded, it
must be verified with a microscope. SGS US Testing verified all 43 results with a 100x microscope.
- In SGS US Testing, the positive control (100% organic pine material) grew to "heavy mold growth." The negative controls had
"no mold growth," which is consistent and predictable with the test protocol.
|
- Our tests are certified and frequent, the results are consistent, and BioBlock® performance effectiveness is validated in
the lab (43 tests) and the marketplace. (Five years no claims)

*SGS US Testing is an independent, certified laboratory that has performed mold and mildew tests for 25 years. They performed
the ASTM D-3273 test of mold and mildew resistance on the 43 tests of Armstrong ceiling material described above. Please visit SGS US Testing to learn about their world leadership position in verification, testing and certification services.
**Armstrong ran one set of 27 tests in 2000 containing sample test results with two samples, and some with three samples.
Per ASTM D3273 7.1, duplicates are allowed instead of triplicates, if agreed upon by the parties involved.
