A MICROBIAL RESISTANCE EVALUATION OF INDOOR MATERIALS
air krete® INSULATION SAMPLE
prepared for air krete®
Executive Summary / Project
Description Air Quality Sciences, Inc. (AQS) is pleased
to present the results of its microbial resistance evaluation
of air krete's indoor material identified as “ air krete®
Insulation Sample”. AQS conducted this study using a
microbial test protocol following the requirements of ASTM
Guideline D 6329-98 (1). This ASTM method is established to
study indoor materials for their ability to support mold growth.
Testing of the indoor material was conducted using static
environmental chambers operating at 75% humidity (considered
a *high normal” for indoor commercial spaces) and 95%
humidity (considered an extreme moisture condition within
buildings). Air Krete's indoor material was inoculated with
two representative indoor molds, Stachvbotrvs chartarum and
Eurotium amstelodami, and growth rates were measured over
a three-week period as the materials were exposed in the two
humidity environments. Mold growth is considered significant
if it exceeds 20% of the initial baseline levels. Test methodology
and results are given in the attached summary reports.
Test Results
Results show that the “ air krete® Insulation Sample”
was resistant to mold growth at both 75% and 95% relative
humidities. Neither molds were found to amplify in the materials
at either humidity.
